From 312f7da2824c82800ee78d6190f12854456957af Mon Sep 17 00:00:00 2001 From: Albert Lee Date: Tue, 27 Sep 2005 17:38:03 +0800 Subject: [PATCH] libata: interrupt driven pio for libata-core - add PIO_ST_FIRST for the state before sending ATAPI CDB or sending "ATA PIO data out" first data block. - add ATA_TFLAG_POLLING and ATA_DFLAG_CDB_INTR flags - remove the ATA_FLAG_NOINTR flag since the interrupt handler is now aware of the states - modify ata_pio_sector() and atapi_pio_bytes() to work in the interrupt context - modify the ata_host_intr() to handle PIO interrupts - modify ata_qc_issue_prot() to initialize states - atapi_packet_task() changed to handle "ATA PIO data out" first data block - support the pre-ATA4 ATAPI device which raise interrupt when ready to receive CDB Signed-off-by: Albert Lee Signed-off-by: Jeff Garzik --- drivers/scsi/libata-core.c | 333 ++++++++++++++++++++++++++++++++++++--------- include/linux/ata.h | 3 + include/linux/libata.h | 4 +- 3 files changed, 271 insertions(+), 69 deletions(-) diff --git a/drivers/scsi/libata-core.c b/drivers/scsi/libata-core.c index c4fcdc30f18c..cc2d1308826e 100644 --- a/drivers/scsi/libata-core.c +++ b/drivers/scsi/libata-core.c @@ -1292,6 +1292,9 @@ retry: ap->cdb_len = (unsigned int) rc;

The value written to the Index register is now a byte offset, no longer an index based upon the width of the Data register. This should fix IndexField problems seen on some machines where the Data register is not exactly one byte wide. The ACPI specification will be clarified on this point. Fixed a problem where several resource descriptor types could overrun the internal descriptor buffer due to size miscalculation: VendorShort, VendorLong, and Interrupt. This was noticed on IA64 machines, but could affect all platforms. Fixed a problem where individual resource descriptors were misaligned within the internal buffer, causing alignment faults on IA64 platforms.

This macro can be defined as necessary to assist kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL macro. The default definition is NULL. Added the ACPI_THREAD_ID type for the return value from acpi_os_get_thread_id(). This allows the host to define this as necessary to simplify kernel integration. The default definition is ACPI_NATIVE_UINT. Valery Podrezov fixed two interpreter problems related to error processing, the deletion of objects, and placing invalid pointers onto the internal operator result stack. http://bugzilla.kernel.org/show_bug.cgi?id=6028 http://bugzilla.kernel.org/show_bug.cgi?id=6151 Increased the reference count threshold where a warning is emitted for large reference counts in order to eliminate unnecessary warnings on systems with large namespaces (especially 64-bit.) Increased the value from 0x400 to 0x800. Due to universal disagreement as to the meaning of the 'c' in the calloc() function, the ACPI_MEM_CALLOCATE macro has been renamed to ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'. ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and ACPI_FREE.

Separate out libata-eh.c. ata_scsi_timed_out(), ata_scsi_error(), ata_qc_timeout(), ata_eng_timeout(), ata_eh_qc_complete() and ata_eh_qc_retry() are moved. No code is changed by this patch.

Note: this breaks userspace and requires users to upgrade to the newest open-iscsi tools. Sorry about his but open-iscsi is still too new to say we have a stable user-kernel api and we were not good nough designers to know that other hw iscsi drivers and iscsid itself would need such changes. Actually we sorta did but at the time we did not have the HW available to us so we could only guess. Luckily, the only tools hooking into the class are the open-iscsi ones or other tools like iscsitart hook into the open-iscsi engine from userspace or prgroams like anaconda call our tools so they are not affected.

To later restart it iscsid needs to be able to rebuild itself and part of that process is matching a session running the kernel with the iscsid representation. To do this the attached patch adds several required iscsi values. If the LLD does not provide them becuase, login is done in userspace, then the transport class and userspace set ths up for the LLD.

The attached patch: - Fixes the TMF issues. If a session is rebuilt then we do not send aborts. - Fixes the problem where if the host reset fired, we would return SUCCESS even though we had not really done anything yet. This ends up causing problem with scsi_error.c's TUR. - If someone has turned on the userspace nop daemon code to try and detect network problems before the scsi command timeout we can now drop and clean up the session before the scsi command timesout and fires the eh speeding up the time it takes for a command to go from one patch to another. For network problems we fail the command with DID_BUS_BUSY so if failfast is set scsi_decide_disposition fails the command up to dm for it to try on another path. - And we had to add some basic iscsi session block code. Previously if we were trying to repair a session we would retrun a MLQUEUE code in the queuecommand. This worked but it was not the most efficient or pretty thing to do since it would take a while to relogin to the target. For iscsi_tcp/open-iscsi a lot of the iscsi error handler is in userspace the block code is pretty bare. We will be adding to that for qla4xxx.

This patch puts the duplicated code in a lib. There is more code to move around but this takes care of the basics. For iscsi_offload if they use the lib we will probably move some things around. For example in the queuecommand we will not assume that the LLD wants to do queue_work, but it is better to handle that later when we know for sure what iscsi_offload looks like (we could probably do this for iscsi_iser though to). Ideally I would like to get the iscsi_transports modules to a place where all they really have to do is put data on the wire, but how to do that will hopefully be more clear when we see other modules like iscsi_offload. Or maybe iscsi_offload will not use the lib and it will just be iscsi_iser and iscsi_tcp and maybe the iscsi_tcp_tgt if that is allowed in mainline.

For this the driver uses page_address() which is broken on highmem. Apart from this the actual calculation of the virtual address is wrong (even without highmem). So, e.g., for reading it reads bytes from the driver to a wrong address and returns wrong data, I guess, for writing it would just output random data to the device. The proper fix, as suggested by many, is to dynamically map data using kmap_atomic(page, KM_BIO_SRC_IRQ) / kunmap_atomic(virt). The reason why it has not been done until now, although I've done some preliminary patches more than a year ago was that nobody interested in fixing this problem was able to reliably reproduce it. Now it changed - with the help from Sebastian Frei (CC'ed) I was able to trigger the PIO path. Thus, I was also able to test and debug it. There are 4 cases when PIO is used in dc395x - data-in / -out with and without scatter-gather. I was able to reproduce and test only data-in with and without SG. So, the data-out path is still untested, but it is also somewhat simpler than the data-in. Fredrik Roubert (also CC'ed) also had PIO triggering on his system, and in his case it was data-out without SG. It would be great if he could test the attached patch on his system, but even if he cannot, I would still request to apply the patch and just wait if anybody cries... Implementation: I put 2 new functions in scsi_lib.c and their declarations in scsi_cmnd.h. I exported them without _GPL, although, I don't feel strongly about that - not many drivers are likely to use them. But there is at least one more - I want to use them in tmscsim.c. Whether these are the right files for the functions and their declarations - not sure either. Actually, they are not scsi-specific, so, might go somewhere around other scattergather magic? They are not platform specific either, and most SG functions are defined under arch/*/... As these issues were discussed previously there were some more routines suggested to manipulate scattergather buffers, I think, some of them were needed around crypto code... So, might be a common place reasonable, like lib/scattergather.c? I am open here.

The GC thread would iterate through all the inodes on the system and check each of their data nodes. It would skip over inodes which had already been used or were already being read in by read_inode(), because their data nodes would have been examined anyway. However, we could sometimes reach the end of the for-each-inode loop and still have some unchecked space left, if an inode we'd skipped was _still_ in the process of being read. This fixes that race by actually waiting for read_inode() to finish rather than just moving on. Thanks to Ladislav Michl for coming up with a reproducible test case and helping to track it down.

It now accepts: Ki, Mi, Gi - the official prefixes for binary multiples, see http://physics.nist.gov/cuu/Units/binary.html, ki - mistake on my side and analog to "k" for decimal multiples, KiB, MiB, GiB - for people that prefer to add a "B" for byte, kiB - combination of the above. There were complaints about not accepting "k" for 1024. This has long been common practice, but is known to lead to confusion. Hence the new SI units and hence block2mtd only accepts units that cannot be confused with decimal units. Diverging from common practice doesn't always please people, even if the change is for the better.

Observe that it effectively does an 'rb_next()' operation to find the next (by value) node in the tree. That is; we go to the victim's right-hand child and then follow left-hand pointers all the way down the tree as far as we can until we find the next node 'node'. We end up with 'node' being either the same immediate right-hand child of 'old', or one of its descendants on the far left-hand side. For a start, we _know_ that 'node' has a parent. We can drop that check. We also know that if 'node's parent is 'old', then 'node' is the right-hand child of its parent. And that if 'node's parent is _not_ 'old', then 'node' is the left-hand child of its parent. So instead of checking for 'node->rb_parent == old' in one place and also checking 'node's heritage separately when we're trying to change its link from its parent, we can shuffle things around a bit and do it like this...

Panicking from an interrupt handler means we fail to EOI the interrupt, and so the second kernel never gets that interrupt ever again. We also see hangs on JS20 where we take interrupts in the second kernel early during boot. This patch fixes both those problems, and although it adds more code to the crash path I think it is the best solution.

This problem can be reproduced each time when the debugger is enabled and soft-reset is used to invoke kdump boot. The first CPU sends an IPI - setting the IPI priority for all secondary cpus (xics_cause_ipi()). But some CPUs will enter into the xmon via soft-reset, i.e, not executing xics_ipi_action(). Hence, IPI is not cleared. When exited from the debugger, one of these CPUs could become the primary kexec CPU. Since the IPI is not cleared, causing this issue in kdump boot. This patch clears and EOI IPI for kexec CPU as well before the kdump boot started.

The goal of doing this was to avoid an infinite loop of resets if a card is obviously dead. However, if the failures are rare, but the machine has a high uptime, this mechanism might still be triggered; this is too harsh. This patch will avoids this problem by decrementing the fail count after an hour. Thus, as long as a pci card BSOD's less than 6 times an hour, it will continue to be reset indefinitely. If it's failure rate is greater than that, it will be taken off-line permanently. This patch is larger than it might otherwise be because it changes indentation by removing a pointless while-loop. The while loop is not needed, as the handler is invoked once fo each event (by schedule_work()); the loop is leftover cruft from an earlier implementation.

I know zilch about the driver model, so I probably botched it in some way, but I've done some tests on an ixp23xx board which uses physmap, and it all seems to work. In order to not break existing physmap users, I've added some compat code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN is defined and != 0. Also, I've changed the default value for CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently compile in physmap (or new, platform-style, users of physmap) don't get burned. This works pretty well -- the new physmap driver is a drop-in replacement for the old one, and works on said ixp23xx board without any code changes needed. (This should hold as long as users don't touch 'physmap_map' directly.) Once all physmap users have been converted to instantiate their own platform devices, the compat code can go. (Or we decide that we can change all the in-tree users at the same time, and never merge the compat code.)

This keeps X from working on the Intel Tiger box. - The current kernel allows UC mmap of the 0-1MB region of /sys/.../legacy_mem even when the chipset doesn't support UC access. This causes an MCA when starting X on HP rx7620 and rx8620 boxes in the default configuration. There's more detail in the Documentation/ia64/aliasing.txt file this adds, but the general idea is that if a region might be covered by a granule-sized kernel identity mapping, any access via /dev/mem or mmap must use the same attribute as the identity mapping. Otherwise, we fall back to using an attribute that is supported according to the EFI memory map, or to using UC if the EFI memory map doesn't mention the region.

The ones of most interest to the Linux + kernel are: + + WB Write-back (cacheable) + UC Uncacheable + WC Write-coalescing + + System memory typically uses the WB attribute. The UC attribute is + used for memory-mapped I/O devices. The WC attribute is uncacheable + like UC is, but writes may be delayed and combined to increase + performance for things like frame buffers. + + The Itanium architecture requires that we avoid accessing the same + page with both a cacheable mapping and an uncacheable mapping[1]. + + The design of the chipset determines which attributes are supported + on which regions of the address space. For example, some chipsets + support either WB or UC access to main memory, while others support + only WB access. + +MEMORY MAP + + Platform firmware describes the physical memory map and the + supported attributes for each region. At boot-time, the kernel uses + the EFI GetMemoryMap() interface. ACPI can also describe memory + devices and the attributes they support, but Linux/ia64 currently + doesn't use this information. + + The kernel uses the efi_memmap table returned from GetMemoryMap() to + learn the attributes supported by each region of physical address + space. Unfortunately, this table does not completely describe the + address space because some machines omit some or all of the MMIO + regions from the map. + + The kernel maintains another table, kern_memmap, which describes the + memory Linux is actually using and the attribute for each region. + This contains only system memory; it does not contain MMIO space. + + The kern_memmap table typically contains only a subset of the system + memory described by the efi_memmap. Linux/ia64 can't use all memory + in the system because of constraints imposed by the identity mapping + scheme. + + The efi_memmap table is preserved unmodified because the original + boot-time information is required for kexec. + +KERNEL IDENTITY MAPPINGS + + Linux/ia64 identity mappings are done with large pages, currently + either 16MB or 64MB, referred to as "granules." Cacheable mappings + are speculative[2], so the processor can read any location in the + page at any time, independent of the programmer's intentions. This + means that to avoid attribute aliasing, Linux can create a cacheable + identity mapping only when the entire granule supports cacheable + access. + + Therefore, kern_memmap contains only full granule-sized regions that + can referenced safely by an identity mapping. + + Uncacheable mappings are not speculative, so the processor will + generate UC accesses only to locations explicitly referenced by + software. This allows UC identity mappings to cover granules that + are only partially populated, or populated with a combination of UC + and WB regions. + +USER MAPPINGS + + User mappings are typically done with 16K or 64K pages. The smaller + page size allows more flexibility because only 16K or 64K has to be + homogeneous with respect to memory attributes. + +POTENTIAL ATTRIBUTE ALIASING CASES + + There are several ways the kernel creates new mappings: + + mmap of /dev/mem + + This uses remap_pfn_range(), which creates user mappings. These + mappings may be either WB or UC. If the region being mapped + happens to be in kern_memmap, meaning that it may also be mapped + by a kernel identity mapping, the user mapping must use the same + attribute as the kernel mapping. + + If the region is not in kern_memmap, the user mapping should use + an attribute reported as being supported in the EFI memory map. + + Since the EFI memory map does not describe MMIO on some + machines, this should use an uncacheable mapping as a fallback. + + mmap of /sys/class/pci_bus/.../legacy_mem + + This is very similar to mmap of /dev/mem, except that legacy_mem + only allows mmap of the one megabyte "legacy MMIO" area for a + specific PCI bus. Typically this is the first megabyte of + physical address space, but it may be different on machines with + several VGA devices. + + "X" uses this to access VGA frame buffers. Using legacy_mem + rather than /dev/mem allows multiple instances of X to talk to + different VGA cards. + + The /dev/mem mmap constraints apply. + + However, since this is for mapping legacy MMIO space, WB access + does not make sense. This matters on machines without legacy + VGA support: these machines may have WB memory for the entire + first megabyte (or even the entire first granule). + + On these machines, we could mmap legacy_mem as WB, which would + be safe in terms of attribute aliasing, but X has no way of + knowing that it is accessing regular memory, not a frame buffer, + so the kernel should fail the mmap rather than doing it with WB. + + read/write of /dev/mem + + This uses copy_from_user(), which implicitly uses a kernel + identity mapping. This is obviously safe for things in + kern_memmap. + + There may be corner cases of things that are not in kern_memmap, + but could be accessed this way. For example, registers in MMIO + space are not in kern_memmap, but could be accessed with a UC + mapping. This would not cause attribute aliasing. But + registers typically can be accessed only with four-byte or + eight-byte accesses, and the copy_from_user() path doesn't allow + any control over the access size, so this would be dangerous. + + ioremap() + + This returns a kernel identity mapping for use inside the + kernel. + + If the region is in kern_memmap, we should use the attribute + specified there. Otherwise, if the EFI memory map reports that + the entire granule supports WB, we should use that (granules + that are partially reserved or occupied by firmware do not appear + in kern_memmap). Otherwise, we should use a UC mapping. + +PAST PROBLEM CASES + + mmap of various MMIO regions from /dev/mem by "X" on Intel platforms + + The EFI memory map may not report these MMIO regions. + + These must be allowed so that X will work. This means that + when the EFI memory map is incomplete, every /dev/mem mmap must + succeed. It may create either WB or UC user mappings, depending + on whether the region is in kern_memmap or the EFI memory map. + + mmap of 0x0-0xA0000 /dev/mem by "hwinfo" on HP sx1000 with VGA enabled + + See https://bugzilla.novell.com/show_bug.cgi?id=140858. + + The EFI memory map reports the following attributes: + 0x00000-0x9FFFF WB only + 0xA0000-0xBFFFF UC only (VGA frame buffer) + 0xC0000-0xFFFFF WB only + + This mmap is done with user pages, not kernel identity mappings, + so it is safe to use WB mappings. + + The kernel VGA driver may ioremap the VGA frame buffer at 0xA0000, + which will use a granule-sized UC mapping covering 0-0xFFFFF. This + granule covers some WB-only memory, but since UC is non-speculative, + the processor will never generate an uncacheable reference to the + WB-only areas unless the driver explicitly touches them. + + mmap of 0x0-0xFFFFF legacy_mem by "X" + + If the EFI memory map reports this entire range as WB, there + is no VGA MMIO hole, and the mmap should fail or be done with + a WB mapping. + + There's no easy way for X to determine whether the 0xA0000-0xBFFFF + region is a frame buffer or just memory, so I think it's best to + just fail this mmap request rather than using a WB mapping. As + far as I know, there's no need to map legacy_mem with WB + mappings. + + Otherwise, a UC mapping of the entire region is probably safe. + The VGA hole means the region will not be in kern_memmap. The + HP sx1000 chipset doesn't support UC access to the memory surrounding + the VGA hole, but X doesn't need that area anyway and should not + reference it. + + mmap of 0xA0000-0xBFFFF legacy_mem by "X" on HP sx1000 with VGA disabled + + The EFI memory map reports the following attributes: + 0x00000-0xFFFFF WB only (no VGA MMIO hole) + + This is a special case of the previous case, and the mmap should + fail for the same reason as above. + +NOTES + + [1] SDM rev 2.2, vol 2, sec 4.4.1. + [2] SDM rev 2.2, vol 2, sec 4.4.6. diff --git a/arch/ia64/kernel/efi.c b/arch/ia64/kernel/efi.c index 12cfedce73b1..c33d0ba7e300 100644 --- a/arch/ia64/kernel/efi.c +++ b/arch/ia64/kernel/efi.c @@ -8,6 +8,8 @@ * Copyright (C) 1999-2003 Hewlett-Packard Co. * David Mosberger-Tang * Stephane Eranian + * (c) Copyright 2006 Hewlett-Packard Development Company, L.P. + * Bjorn Helgaas * * All EFI Runtime Services are not implemented yet as EFI only * supports physical mode addressing on SoftSDV.

It was stuck at zero. From the RFC, it looks like if the login response PDU has a successful status then we should be incrementing that value. Also from the RFC, it looks like if when we drop a connection then reconnect, we should be using the exp_statsn from the old connection in the next relogin attempt.

It is is used just for permitting tcp_read_sock to read the portion of data in the socket. When iscsi_tcp_data_recv sees a partial header, it sets desc.count. However, it is possible that the next skb (containing the rest of the header) still does not come. So I'm not sure that this scheme is completely correct. Ideally, we should use the exact length of the data in the socket for desc.count. However, it is not so simple (see SIOCINQ in tcp_ioctl). So I think that iscsi_tcp_data_recv can just stop playing with desc.count and tell tcp_read_sock to read the all skbs. As proposed already, if iscsi_tcp_data_ready sets desc.count to non-zero, tcp_read_sock does that.

There are some significant differences from previous version posted at last December. The biggest change is addition of EBS(Erase Block Summary) support. Currently, both kernel and usermode utility (sumtool) can recognize xattr nodes which have JFFS2_NODETYPE_XATTR/_XREF nodetype. In addition, some bugs are fixed. - A potential race condition was fixed. - Unexpected fail when updating a xattr by same name/value pair was fixed. - A bug when removing xattr name/value pair was fixed. The fundamental structures (such as using two new nodetypes and exclusion mechanism by rwsem) are unchanged. But most of implementation were reviewed and updated if necessary. Espacially, we had to change several internal implementations related to load_xattr_datum() to avoid a potential race condition.

In original implementation, jffs2_garbage_collect_xattr(c, ic) returns with holding a spinlock if 'ic' is inode_cache. But it returns after releasing a spinlock if 'ic' is xattr_datum/ref. It looks so confusable behavior. Thus, this patch makes caller manage locking/unlocking.

Memory is allocated to the variable 'name' with kmalloc() by the parse_name() function, but if we leave by way of the parse_err() macro, then that memory is never kfree()'d, nor is it ever used with register_device() so it won't be freed later either - leak. Found by the Coverity checker as #593 - simple fix below.

We currently get fairly poor behaviour with files which get many short writes, such as system logs. This is because we end up with many tiny data nodes, and the rbtree gets massive. None of these nodes are actually obsolete, so they are counted as 'clean' space. Eraseblocks can be entirely full of these nodes (which are REF_NORMAL instead of REF_PRISTINE), and still they count entirely towards 'used_size' and the eraseblocks can sit on the clean_list for a long time without being picked for GC. One way to alleviate this in the long term is to account REF_NORMAL space separately from REF_PRISTINE space, rather than counting them both towards used_size. Then these eraseblocks can be picked for GC and the offending nodes will be garbage collected. The short-term fix, though -- which probably makes sense even if we do eventually implement the above -- is to merge these nodes as they're written. When we write the last byte in a page, write the _whole_ page. This obsoletes the earlier nodes in the page _immediately_ and we don't even need to wait for the garbage collection to do it.

This can be _very_ suboptimal on architectures like ARM. Ideally, we want an attribute which just tells GCC not to do any padding, without the alignment side-effects. In the absense of that, we'll just drop the 'packed' attribute and hope that everything stays as it was (which to be fair is fairly much what we expect).

This patch adds shost->host_eh_scheduled to implement such behavior. Currently the only user of this feature is libata and no general interface is defined. This patch simply adds handling for host_eh_scheduled where needed and exports scsi_eh_wakeup() to modules. The rest is upto libata. This is the result of the following discussion. http://thread.gmane.org/gmane.linux.scsi/23853/focus=9760 In short, SCSI host is not supposed to know about exceptions unrelated to specific device or command. Such exceptions should be handled by transport layer proper. However, the distinction is not essential to ATA and libata is planning to depart from SCSI, so, for the time being, libata will be using SCSI EH to handle such exceptions.

These functions replace scr_{read|write}() and sata_dev_present(). Major difference between between the new SCR functions and the old ones is that the new ones have a way to signal error to the caller. This makes handling SCR-available and SCR-unavailable cases in the same path easier. Also, it eases later PM implementation where SCR access can fail due to various reasons. ata_port_{online|offline}() functions return 1 only when they are affirmitive of the condition. e.g. if SCR is unaccessible or presence cannot be determined for other reasons, these functions return 0. So, ata_port_online() != !ata_port_offline(). This distinction is useful in many exception handling cases.

This change is necessary for later PM support because devices and links should be identified differently depending on how they are attached. This also helps unifying device id strings. Currently, there are two forms in use (P is the port number D device number) - 'ataP(D):', and 'ataP: dev D '. These macros also make it harder to forget proper ID string (e.g. printing only port number when a device is in question). Debug message handling can be integrated into these printk macros by passing debug type and level via @lv.

Every qc starts owned by normal execution path - PIO, interrupt or whatever. When an exception condition occurs which affects the qc, the qc gets scheduled for EH. Note that some events (say, link lost and regained, command timeout) may schedule qc's which are not directly related but could have been affected for EH too. Scheduling for EH is atomic w.r.t. ap->host_set->lock and once schedule for EH, normal execution path is not allowed to access the qc in whatever way. (PIO synchronization acts a bit different and will be dealt with later) This patch make ata_qc_from_tag() check whether a qc is active and owned by normal path before returning it. If conditions don't match, NULL is returned and thus access to the qc is denied. __ata_qc_from_tag() is the original ata_qc_from_tag() and is used by libata core/EH layers to access inactive/failed qc's.

This patch implements one of them - completing a qc with ATA_QCFLAG_FAILED set or with non-zero qc->err_mask. ALL such qc's are examined by EH. New EH schedules a qc for EH from completion iff ->error_handler is implemented, qc is marked as failed or qc->err_mask is non-zero and the command is not an internal command (internal cmd is handled via ->post_internal_cmd). The EH scheduling itself is performed by asking SCSI midlayer to schedule EH for the specified scmd. For drivers implementing old-EH, nothing changes. As this change makes ata_qc_complete() rather large, it's not inlined anymore and __ata_qc_complete() is exported to other parts of libata for later use.

Also, libata makes sure that no new qc gets issued to a frozen port. A frozen port is thawed after a reset operation completes successfully, so reset methods must do its job while the port is frozen. During initialization all ports get frozen before requesting IRQ, so reset methods are always invoked on a frozen port. Optional ->freeze and ->thaw operations notify LLDD that the port is being frozen and thawed, respectively. LLDD can disable/enable hardware interrupt in these callbacks if the controller's IRQ mask can be changed dynamically. If the controller doesn't allow such operation, LLDD can check for frozen state in the interrupt handler and ack/clear interrupts unconditionally while frozen.

As the state of the controller is unknown if a qc has timed out, the port is frozen in such cases. Note that ata_scsi_timed_out() isn't used for new EH. This is because a timed out qc cannot be claimed by EH without freezing the port and freezing the port in ata_scsi_timed_out() results in unnecessary abortion of other active qcs. ata_scsi_timed_out() can be removed once all drivers are converted to new EH.

Also, when ata_exec_internal() detects a timeout condition and new EH is in place, it freezes the port as timeout for normal commands would do. Note that ata_port_flush_task() is called regardless of wait_for_completion status. This is necessary as exceptions unrelated to the qc can abort the qc, in which case PIO task could still be running after the wait for completion returns.

Execution path describes detected error condition in ap->eh_info and EH recovers the port using it. To avoid missing error conditions detected during EH, EH makes its own copy of eh_info and clears it on entry allowing error info to accumulate during EH. Most EH states including EH's copy of eh_info are stored in ap->eh_context (struct ata_eh_context) which is owned by EH and thus doesn't require any synchronization to access and alter. This standardized context makes it easy to integrate various parts of EH and extend EH to handle multiple links (for PM).

Note that NCQ commands don't use ata_rwcmd_protocol() to choose ATA command. This is because, unlike non-NCQ RW commands, NCQ commands can only be used for NCQ protocol and FUA handling is done with a flag rather than separate command. NCQ enabled device will have queue depth larger than one but no two non-NCQ commands can be issued simultaneously, neither can a non-NCQ command and NCQ commands. This patch makes ata_scsi_translate() return SCSI_MLQUEUE_DEVICE_BUSY if such exclusion is necessary. SCSI midlayer will retry the command later. As SCSI midlayer always retries once a command completes, this doesn't incur unnecessary delays and as most commands will be NCQ ones for NCQ device, so the overhead should be negligible. Initial implementation is from Jens Axboe and using SCSI_MLQUEUE_DEVICE_BUSY for exclusion is suggested by Jeff Garzik.

So, the current driver allows nand_base.c to drive -CE manually during the entire sector read. When the PCMCIA driver is enabled however, occasionally the ECC errors occur on NAND reads. This happens because the PCMCIA driver polls sockets periodically and reads one of the board's control/status regs (BCSRs) which are on the same static bus as the NAND flash, and just use another chip select (and the NOR flash also resides on that bus), so as the NAND driver forces NAND chip select asserted and the -RE signal is shared, a contention occurs on the static bus when BCSR or NOR flash is read while we're reading from NAND. So, we either can't keep interrupts enabled during the whole NAND sector read (which is hardly acceptable), or have to implement some interlocking scheme between multiple drivers (which is painful, and makes me shudder :-). There's a third way which has proven to work: to force -CE asserted only while we're waiting for a NAND chip to become ready after a read command, disabling interrupts for a maximum of 25 microseconds (according to Toshiba TC58DVM92A1FT00 datasheet -- this chip is mentioned in the board schematics); for Samsung NAND chip which seems to be actually used this delay is even less, 12 us.

I hope the patch will not get damaged as I'm posting it from gmail account, thanks to Jorn. The patch adds previously missing concat_writev(), concat_writev_ecc(), concat_block_isbad(), concat_block_markbad() functions to make concatenation layer compatible with Sibley and NAND chips. Patch has been cleared from whitespaces, fixed some lines of code as requested. Also I have added code for alignment check that should support Jorn's "writesize" patch.

Because of this, if a broken PCI card is present, the kernel will attempt to reset it an infinite number of times. (This is annoying but mostly harmless: each reset takes about 10-20 seconds, and uses almost no CPU time). This patch preserves the failure count across resets.

In particular, it's not early enough to do things like mem=x or crashkernel=blah, which is annoying. So do it earlier. I've checked all the early param handlers, and none of them look like they should have any trouble with this. I haven't tested the booke_wdt ones though.

And as benh pointed out I wrote two of them. Now that we parse command line parameters earlier we can clean this mess up. Moving the parsing out of prom_init means the device tree might be allocated above the memory limit. If that happens we'd have to move it. As it happens we already have logic to do that for kdump, so just genericise it. This also means we might have reserved regions above the memory limit, if we do the bootmem allocator will blow up, so we have to modify lmb_enforce_memory_limit() to truncate the reserves as well. Tested on P5 LPAR, iSeries, F50, 44p. Tested moving device tree on P5 and 44p and F50.

The following patch will explicitly reserve the "blob" as it was given to us and stops prom_init.c from creating a reserved mapping for the blob.

Both of these additional module parameters deal with embedded, non-intel or complicated system scenarios. Aif_timeout can be increased past the default 2 minute timeout to drop application registrations when a system has an unusually high event load resulting from continuing management requests, or simultaneous builds, or sluggish user space as a result of system load. Startup_timeout can be increased past the default 3 minute timeout to drop an adapter initialization for systems that have a very large number of targets, or slow to spin-up targets, or a complicated set of array configurations that extend the time for the firmware to declare that it is operational. This timeout would only have an affect on non-intel based systems, as the (more patient) BIOS would generally be where the startup delay would be dealt with.

But it can still happen even if it's unlikely. If the first call that allocates 'PhysicalDeviceInfo' fails but the one that allocates 'InquiryUnitSerialNumber' succeeds, then we will leak the memory allocated to 'InquiryUnitSerialNumber' when the variable goes out of scope. A simple fix for this is to change the existing code that frees 'PhysicalDeviceInfo' if that one was allocated but 'InquiryUnitSerialNumber' was not, into a check for either pointer being NULL and if so just free both. This is safe since kfree() can deal with being passed a NULL pointer and it avoids the leak. While I was there I also removed the casts of the kmalloc() return value since it's pointless. I also updated the driver version since this patch changes the workings of the code (however slightly). This issue could probably be fixed a lot more elegantly, but the code is a big mess IMHO and I just took the least intrusive route to a fix that I could find instead of starting on a cleanup as well (that can come later). Please consider for inclusion.

This will cause commands to needlessly swing around on us and remove goofy recovery_failed field and replace with state value. And do not start recovery from within the host reset function. This causeis too many problems becuase open-iscsi was desinged to call out to userspace then have userpscae decide if we should go into recovery or kill the session.

We used to read the last page of the eraseblock twice -- once to find the offset of the summary node, and again to actually _read_ the summary node. Now we read the last page only once, and read more only if we need to. We also don't allocate a new buffer just for the summary code -- we use the buffer which was already allocated for the scan. Better still, if the 'buffer' for the scan is actually just a pointer directly into NOR flash, we use that too, avoiding the memcpy() which we used to do.

We'll actually keep a 'TEST_TOTLEN' macro set for now, and keep doing some paranoia checks to make sure it's all working correctly. But if TEST_TOTLEN is unset, the size of struct jffs2_raw_node_ref drops from 16 bytes to 12 on 32-bit machines. That's a saving of about half a megabyte of memory on the OLPC prototype board, with 125K or so nodes in its 512MiB of flash.

Those flashes disallow clearing of single bits, unlike regular NOR flashes, so the new flag models their behaviour better. o Remove MTD_ECC. After the STMicro/Sibley merge, this flag is only set and never checked.

We don't need the upper layers to deal with the physical offset. It's _always_ c->nextblock->offset + c->sector_size - c->nextblock->free_size so we might as well just let the actual write functions deal with that.

As the first step towards eliminating the ref->next_phys member and saving memory by using an _array_ of struct jffs2_raw_node_ref per eraseblock, stop the write functions from allocating their own refs; have them just _reserve_ the appropriate number instead. Then jffs2_link_node_ref() can just fill them in. Use a linked list of pre-allocated refs in the superblock, for now. Once we switch to an array, it'll just be a case of extending that array.

The code in it is 90%+ common with the powerpc specific version, so the powerpc version is redundant. This patch makes the necessary changes to use the generic bitops in powerpc, and removes the powerpc specific version.

The handling of out of band data on NAND was accompanied by tons of fruitless discussions and halfarsed patches to make it work for a particular problem. Sufficiently annoyed by I all those "I know it better" mails and the resonable amount of discarded "it solves my problem" patches, I finally decided to go for the big rework. After removing the _ecc variants of mtd read/write functions the solution to satisfy the various requirements was to refactor the read/write _oob functions in mtd. The major change is that read/write_oob now takes a pointer to an operation descriptor structure "struct mtd_oob_ops".instead of having a function with at least seven arguments. read/write_oob which should probably renamed to a more descriptive name, can do the following tasks: - read/write out of band data - read/write data content and out of band data - read/write raw data content and out of band data (ecc disabled) struct mtd_oob_ops has a mode field, which determines the oob handling mode. Aside of the MTD_OOB_RAW mode, which is intended to be especially for diagnostic purposes and some internal functions e.g. bad block table creation, the other two modes are for mtd clients: MTD_OOB_PLACE puts/gets the given oob data exactly to/from the place which is described by the ooboffs and ooblen fields of the mtd_oob_ops strcuture. It's up to the caller to make sure that the byte positions are not used by the ECC placement algorithms. MTD_OOB_AUTO puts/gets the given oob data automaticaly to/from the places in the out of band area which are described by the oobfree tuples in the ecclayout data structre which is associated to the devicee. The decision whether data plus oob or oob only handling is done depends on the setting of the datbuf member of the data structure. When datbuf == NULL then the internal read/write_oob functions are selected, otherwise the read/write data routines are invoked. Tested on a few platforms with all variants. Please be aware of possible regressions for your particular device / application scenario Disclaimer: Any whining will be ignored from those who just contributed "hot air blurb" and never sat down to tackle the underlying problem of the mess in the NAND driver grown over time and the big chunk of work to fix up the existing users. The problem was not the holiness of the existing MTD interfaces. The problems was the lack of time to go for the big overhaul. It's easy to add more mess to the existing one, but it takes alot of effort to go for a real solution. Improvements and bugfixes are welcome!

This patch also implements ata_std_prereset(). Most controllers should be able to use this function directly or with some wrapping. After hotplug, different controllers need different actions to resume the PHY and detect the newly attached device. Controllers can be categorized as follows. * Controllers which can wait for the first D2H FIS after hotplug. Note that if the waiting is implemented by polling TF status, there needs to be a way to set BSY on PHY status change. It can be implemented by hardware or with the help of the driver. * Controllers which can wait for the first D2H FIS after sending COMRESET. These controllers need to issue COMRESET to wait for the first FIS. Note that the received D2H FIS could be the first D2H FIS after POR (power-on-reset) or D2H FIS in response to the COMRESET. Some controllers use COMRESET as TF status synchronization point and clear TF automatically (sata_sil). * Controllers which cannot wait for the first D2H FIS reliably. Blindly issuing SRST to spinning-up device often results in command issue failure or timeout, causing extended delay. For these controllers, ata_std_prereset() explicitly waits ATA_SPINUP_WAIT (currently 8s) to give newly attached device time to spin up, then issues reset. Note that failing to getting ready in ATA_SPINUP_WAIT is not critical. libata will retry. So, the timeout needs to be long enough to spin up most devices. LLDDs can tell ata_std_prereset() which of above action is needed with ATA_FLAG_HRST_TO_RESUME and ATA_FLAG_SKIP_D2H_BSY flags. These flags are PHY-specific property and will be moved to ata_link later. While at it, this patch unifies function typedef's such that they all have named arguments.

Further improvements are possible, in both 2 and 4 ports versions, we can get all status with only one readl and using custom bmdma operations can further cut down register accesses.

While loading, ata_host_add() simply schedules probing and invokes EH. After EH completes, ata_host_add() scans and assicates them with SCSI devices. EH path is slightly modified to handle this (e.g. no autopsy during bootplug). The SCSI part is left in ata_host_add() because it's shared with legacy path and to keep probing order as before (ATA scan all ports in host_set then attach all).

(LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS (rev 01)) o Problem is easily reproducible, if system crashed while some disk activity like cp operation was going on. o After a system crash, devices are not shutdown and capture kernel starts booting while skipping BIOS. Hence underlying device is left in operational state. In this case scsi contoller was left with interrupt line asserted reply FIFO was not empty. When driver starts initializing in the second kernel, it receives the interrupt the moment request_irq() is called. Interrupt handler, reads the message from reply FIFO and tries to access the associated message frame and panics, as in the new kernel's context that message frame is not valid at all. o In this scenario, probably we should delay the request_irq() call.

There was a problem with the construction of the security blob in the older code. Currently requires /proc/fs/cifs/Experimental to be set to 2 and /proc/fs/cifs/SecurityFlags to be set to 0x4004 (to require using NTLMv2 instead of default of NTLM) Next we will check signing to make sure optional NTLMv2 packet signing also works.

While the freeing extent function has sorted the extents based on AGF number before entering into transaction, however, when the file system space is very limited, the allocation of space would try every AGF to get space allocated, this could potentially cause out-of-order locking, thus deadlock could happen. This fix mitigates the scarce space for allocation by setting aside a few blocks without reservation, and avoid deadlock by maintaining ascending order of AGF locking.

This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

That would cause the hardware to possibly to a write back to the hash table to set it on the first store access, which in addition to being a performance issue, might also hit a bug when running with native hash management (non-HV) as our code is specifically optimized for the case where no write back happens. Thus there is a very small therocial window were a hash PTE can become corrupted if that HPTE has just been upgraded to read write, a store access happens on it, and that races with another processor evicting that same slot. Since eviction (caused by an almost full hash) is extremely rare, the bug is very unlikely to happen fortunately. This fixes by allowing the updating of the protection bits in the native hash handling to also set (but not clear) the "C" bit, and, in order to also improve performances in the general case, by always setting that bit on newly inserted hash PTE so that writeback really never happens.

This new prctl is intended for changing the execution mode of the processor, on processors that support both a little-endian mode and a big-endian mode. It is intended for use by programs such as instruction set emulators (for example an x86 emulator on PowerPC), which may find it convenient to use the processor in an alternate endianness mode when executing translated instructions. Note that this does not imply the existence of a fully-fledged ABI for both endiannesses, or of compatibility code for converting system calls done in the non-native endianness mode. The program is expected to arrange for all of its system call arguments to be presented in the native endianness. Switching between big and little-endian mode will require some care in constructing the instruction sequence for the switch. Generally the instructions up to the instruction that invokes the prctl system call will have to be in the old endianness, and subsequent instructions will have to be in the new endianness.

This also extends the alignment exception handler to be able to fix up alignment exceptions that occur in little-endian mode, both for "PowerPC" little-endian and true little-endian. We always enter signal handlers in big-endian mode -- the support for little-endian mode does not amount to the creation of a little-endian user/kernel ABI. If the signal handler returns, the endian mode is restored to what it was when the signal was delivered. We have two new kernel CPU feature bits, one for PPC little-endian and one for true little-endian. Most of the classic 32-bit processors support PPC little-endian, and this is reflected in the CPU feature table. There are two corresponding feature bits reported to userland in the AT_HWCAP aux vector entry. This is based on an earlier patch by Anton Blanchard.

Our "benchmark" is ls -R /etc, which spits out about 27866 characters. The theoretical maximum speed would be about 2.2 seconds, the current code takes ~50 seconds. The core of the problem is that sometimes when the tty layer asks us to push characters the firmware isn't able to handle some or all of them, and so returns an error. The current code sees this and just returns to the tty code with the buffer half sent. The khvcd thread will eventually wake up and try to push more characters, which will usually work because by then the firmware's had time to make room. But the khvcd thread only wakes up every 10 milliseconds, which isn't fast enough. So change the khvcd thread logic so that if there's an incomplete write we yield() and then immediately try writing again. Doing so makes POLL_QUICK and POLL_WRITE synonymous, so remove POLL_QUICK. With this patch our "benchmark" takes ~2.8 seconds.

This improves DRC behavior on the server by using the same port when reconnecting for the same mount point, but using a different port for fresh mounts. The Linux TCP implementation already does this for nonprivileged ports. Note that TCP sockets in TIME_WAIT will prevent quick reuse of a random ephemeral port number by leaving the port INUSE until the connection transitions out of TIME_WAIT. Test plan: Connectathon against every known server implementation using multiple mount points. Locking especially.

NFS_ROOT starts up before the random driver, though, so get_random_bytes doesn't set a random XID for NFS_ROOT. This causes NFS_ROOT mount points to reuse XIDs every time the client is booted. If the client boots often enough, the server will start serving old replies out of its DRC. Use net_random() instead. Test plan: I/O intensive workloads should perform well and generate no errors. Traces taken during client reboots should show that NFS_ROOT mounts use unique XIDs after every reboot.

(*) fs/nfs/super.c Superblock management functions for NFS and NFS4, normal access, clones and referrals. The NFS4 superblock functions _could_ move out into a separate conditionally compiled file, but it's probably not worth it as there're so many common bits. (*) fs/nfs/namespace.c Some namespace-specific functions have been moved here. (*) fs/nfs/nfs4namespace.c NFS4-specific namespace functions (this could be merged into the previous file). This file is conditionally compiled. (*) fs/nfs/internal.h Inter-file declarations, plus a few simple utility functions moved from fs/nfs/inode.c. Additionally, all the in-.c-file externs have been moved here, and those files they were moved from now includes this file. For the most part, the functions have not been changed, only some multiplexor functions have changed significantly. I've also: (*) Added some extra banner comments above some functions. (*) Rearranged the function order within the files to be more logical and better grouped (IMO), though someone may prefer a different order. (*) Reduced the number of #ifdefs in .c files. (*) Added missing __init and __exit directives.

The effect of this timer is to extend the total time that a target will be missing beyond the value associated with the transport's timer. This patch changes the firmware timer to a default of one second which significantly reduces the lag between when a target goes missing and the notification of the fibre channel transport.

This patch installs a "SETUP RESET" handler which calls fc_remote_port_delete() for all registered rports. This blocks the target which prevents the loop. Additionally, should the reset fail to complete, the transport will now terminate i/o to the target.

IRQ stays asserted even after SIEN is masked and IRQ is acked. Also, even while frozen, any SATA PHY event including hardreset raises SATA IRQ. Clearing SError seems to be the only way to deassert SATA IRQ. This patch makes sil_host_intr() clear SError on SATA IRQs and ignore SATA IRQs reported while frozen so that hardreset doesn't trigger hotplug event (which ends up hardresetting again). In such cases, the port still gets re-frozen to minimize the danger of screaming interrupts. This results in one nil EH repeat on controllers with broken SIEN but other than that does no harm.

There was no connection between the two hosts making it impossible to traverse all ports related to the controller. This patch adds host_set->next which points to the second host_set and makes ata_pci_remove_one() remove all associated host_sets. * On device removal, all ports hanging off the device are properly detached. Prior to this patch, ports on the first host_set weren't detached casuing oops on driver unloading. * On device removal, both host_sets are properly freed This will also be used by new power management code to suspend and resume all ports of a controller. host_set/port representation will be improved to handle legacy controllers better and this host_set linking will go away with it.

If this interrupt occurs, the "LinkControl.CycleMaster" bit of the host controller is reseted. This implies, that the host controller does not send "cycle start" packet anymore freezing then the isochronous communication. The management of the interrupt added by the patch is that when the interrupt occurs, the OHCI irq handler prints a kernel log warning and then sets the "LinkControl.CycleMaster" bit again resuming the isochronous communication.

A probing function is added to nodemgr's config ROM fetching routine which adjusts the allowable speed if an access problem was encountered. Pros and Cons of the approach: + minimum code footprint to support this less widely used hardware + nearly no overhead for unaffected hardware - ineffective before nodemgr began to read the ROM of affected nodes - ineffective if ieee1394 is loaded with disable_nodemgr=1 The speed map CSRs which are published to the bus are not touched by the patch.

Like in patch ''ohci1394, sbp2: fix "scsi_add_device failed" with PL-3507 based devices'', 1 TeraByte is chosen as physical upper bound. This leaves a window for the middle address range. This choice is only relevant for adapters which actually have a programmable pysical upper bound register. (Only ALi and Fujitsu adapters are known for this. Most adapters have a fixed bound at 4 GB.) The middle address range is suitable for posted writes. AFAIK, PCILynx does not support physical DMA nor posted writes, therefore no equivalent change in the pcilynx driver is necessary. There is also a driver for GP2Lynx, although not in mainline Linux. I assume this hardware does not support these OHCI features either.

I found that unloading the ohci1394 module before suspend and reloading it after resume made the problem go away. Diffing the dmesg output from resume, with and without the module loaded, I found that with the module loaded I was missing these: PM: Writing back config space on device 0000:02:00.0 at offset 1. (Was 2100080, writing 2100007) PM: Writing back config space on device 0000:02:00.0 at offset 3. (Was 0, writing 8008) PM: Writing back config space on device 0000:02:00.0 at offset 4.

(Was 20000100, writing 2000010a) The default PCI driver performs the pci_restore_state when no driver is loaded for the device. When the ohci1394 driver is loaded, it is supposed to do this, however it appears not to do so. I created the patch below and tested it, and it appears to resolve the suspend problems I was having with the module loaded. I only added in the pci_save_state and pci_restore_state - however, though I know little of this hardware, surely the driver should really be doing more than this when suspending and resuming? Currently it does almost nothing, what if there are commands in progress, etc?

Since there are about 1000 static nodes in a typical system, this will decrease memory use for cache implementations that minimize per-allocation overhead (such as a slab allocator.) Removed the reference count mechanism for internal namespace nodes, since it was deemed unnecessary. This reduces the size of each namespace node by about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case, and 32 bytes for the 64-bit case. Optimized several internal data structures to reduce object size on 64-bit platforms by packing data within the 64-bit alignment. This includes the frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static instances corresponding to the namespace objects. Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1" and "Windows 2006". Split the allocation tracking mechanism out to a separate file, from utalloc.c to uttrack.c. This mechanism appears to be only useful for application-level code. Kernels may wish to not include uttrack.c in distributions. Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING macros.)

With this support, all current and known ACPI tables are now defined in the ACPICA headers and are available for use by device drivers and other software. Implemented support to allow tables that contain ACPI names with invalid characters to be loaded. Previously, this would cause the table load to fail, but since there are several known cases of such tables on existing machines, this change was made to enable ACPI support for them. Also, this matches the behavior of the Microsoft ACPI implementation. https://bugzilla.novell.com/show_bug.cgi?id=147621 Fixed a couple regressions introduced during the memory optimization in the 20060317 release. The namespace node definition required additional reorganization and an internal datatype that had been changed to 8-bit was restored to 32-bit. (Valery Podrezov) Fixed a problem where a null pointer passed to acpi_ut_delete_generic_state() could be passed through to acpi_os_release_object which is unexpected. Such null pointers are now trapped and ignored, matching the behavior of the previous implementation before the deployment of acpi_os_release_object(). (Valery Podrezov, Fiodor Suietov) Fixed a memory mapping leak during the deletion of a SystemMemory operation region where a cached memory mapping was not deleted. This became a noticeable problem for operation regions that are defined within frequently used control methods. (Dana Meyers) Reorganized the ACPI table header files into two main files: one for the ACPI tables consumed by the ACPICA core, and another for the miscellaneous ACPI tables that are consumed by the drivers and other software. The various FADT definitions were merged into one common section and three different tables (ACPI 1.0, 1.0+, and 2.0) Signed-off-by: Bob Moore Signed-off-by: Len Brown --- arch/i386/kernel/acpi/boot.c | 4 +- drivers/acpi/bus.c | 2 +- drivers/acpi/dispatcher/dsmethod.c | 2 +- drivers/acpi/dispatcher/dswexec.c | 1 - drivers/acpi/events/evrgnini.c | 13 +- drivers/acpi/executer/exdump.c | 6 +- drivers/acpi/executer/exnames.c | 2 +- drivers/acpi/hardware/hwtimer.c | 4 +- drivers/acpi/namespace/nsalloc.c | 2 + drivers/acpi/namespace/nsdump.c | 3 + drivers/acpi/namespace/nssearch.c | 50 +-- drivers/acpi/parser/psloop.c | 12 + drivers/acpi/parser/psscope.c | 4 +- drivers/acpi/resources/rslist.c | 8 +- drivers/acpi/system.c | 2 +- drivers/acpi/tables.c | 4 +- drivers/acpi/tables/tbconvrt.c | 31 +- drivers/acpi/tables/tbrsdt.c | 3 +- drivers/acpi/tables/tbutils.c | 122 ++++--- drivers/acpi/tables/tbxfroot.c | 9 +- drivers/acpi/utilities/utdebug.c | 38 ++- drivers/acpi/utilities/utdelete.c | 16 +- drivers/acpi/utilities/utglobal.c | 2 +- drivers/acpi/utilities/utinit.c | 6 +- drivers/acpi/utilities/utmisc.c | 104 +++++- drivers/acpi/utilities/utresrc.c | 6 +- drivers/acpi/utilities/utstate.c | 10 +- include/acpi/acconfig.h | 2 +- include/acpi/acdisasm.h | 141 +++++++- include/acpi/acglobal.h | 7 +- include/acpi/aclocal.h | 14 +- include/acpi/acmacros.h | 7 +- include/acpi/acobject.h | 4 + include/acpi/acparser.h | 9 +- include/acpi/acpi_bus.h | 2 +- include/acpi/acpiosxf.h | 2 - include/acpi/acstruct.h | 2 +- include/acpi/actables.h | 6 +- include/acpi/actbl.h | 400 +++++++++++++---------- include/acpi/actbl1.h | 639 +++++++++++++++++++++++++++++++++---- include/acpi/actbl2.h | 230 +------------ include/acpi/acutils.h | 10 +- include/acpi/platform/acenv.h | 4 +- 43 files changed, 1314 insertions(+), 631 deletions(-) diff --git a/arch/i386/kernel/acpi/boot.c b/arch/i386/kernel/acpi/boot.c index 033066176b3e..a6fe91225202 100644 --- a/arch/i386/kernel/acpi/boot.c +++ b/arch/i386/kernel/acpi/boot.c @@ -621,9 +621,9 @@ extern u32 pmtmr_ioport;

This optimization could cause problems because it could allow _INI methods to be run within a not-present device subtree (If a not-present device had no _INI, _STA would not be run, the not-present status would not be discovered, and the children of the device would be incorrectly traversed.) Implemented a new _STA optimization where namespace subtrees that do not contain _INI are identified and ignored during device initialization. Selectively running _STA can significantly improve boot time on large machines (with assistance from Len Brown.) Implemented support for the device initialization case where the returned _STA flags indicate a device not-present but functioning. In this case, _INI is not run, but the device children are examined for presence, as per the ACPI specification. Implemented an additional change to the IndexField support in order to conform to MS behavior. The value written to the Index Register is not simply a byte offset, it is a byte offset in units of the access width of the parent Index Field. (Fiodor Suietov) Defined and deployed a new OSL interface, acpi_os_validate_address(). This interface is called during the creation of all AML operation regions, and allows the host OS to exert control over what addresses it will allow the AML code to access. Operation Regions whose addresses are disallowed will cause a runtime exception when they are actually accessed (will not affect or abort table loading.) Defined and deployed a new OSL interface, acpi_os_validate_interface(). This interface allows the host OS to match the various "optional" interface/behavior strings for the _OSI predefined control method as appropriate (with assistance from Bjorn Helgaas.) Restructured and corrected various problems in the exception handling code paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod (with assistance from Takayoshi Kochi.) Modified the Linux source converter to ignore quoted string literals while converting identifiers from mixed to lower case. This will correct problems with the disassembler and other areas where such strings must not be modified. The ACPI_FUNCTION_* macros no longer require quotes around the function name. This allows the Linux source converter to convert the names, now that the converter ignores quoted strings.

The major difference is that the new interface does not have a Priority parameter, this appeared to be useless and has been replaced by a Type parameter. The Type tells the OS what type of execution is being requested, such as global lock handler, notify handler, GPE handler, etc. This allows the host to queue and execute the request as appropriate for the request type, possibly using different work queues and different priorities for the various request types. This enables fixes for multithreading deadlock problems such as http://bugzilla.kernel.org/show_bug.cgi?id=5534 (Alexey Starikovskiy and Bob Moore) Fixed a possible memory leak associated with the support for the so-called "implicit return" ACPI extension. Reported by FreeBSD (Fiodor Suietov) http://bugzilla.kernel.org/show_bug.cgi?id=6514 Fixed a problem with the Load() operator where a table load from an operation region could overwrite an internal table buffer by up to 7 bytes and cause alignment faults on IPF systems.

(With assistance from Mikhail Kouzmich) Fixed a problem with the CopyObject operator where the first parameter was not typed correctly for the parser, interpreter, compiler, and disassembler. Caused various errors and unexpected behavior. Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits produced incorrect results with some C compilers. Since the behavior of C compilers when the shift value is larger than the datatype width is apparently not well defined, the interpreter now detects this condition and simply returns zero as expected in all such cases.

This change should eliminate all problems caused by attempting to acquire a semaphore at interrupt level, and it means that all ACPICA external interfaces that directly access the ACPI hardware can be safely called from interrupt level. Fixed a regression introduced in 20060526 where the ACPI device initialization could be prematurely aborted with an AE_NOT_FOUND if a device did not have an optional _INI method. Fixed an IndexField issue where a write to the Data Register should be limited in size to the AccessSize (width) of the IndexField itself. (BZ 433, Fiodor Suietov) Fixed problem reports (Valery Podrezov) integrated: - Allow store of ThermalZone objects to Debug object. http://bugzilla.kernel.org/show_bug.cgi?id=5369 http://bugzilla.kernel.org/show_bug.cgi?id=5370 Fixed problem reports (Fiodor Suietov) integrated: - acpi_get_table_header() doesn't handle multiple instances correctly (BZ 364) Removed four global mutexes that were obsolete and were no longer being used.

This patch lets us use 64k hardware pages for most user processes on such machines (assuming the kernel has been configured with CONFIG_PPC_64K_PAGES=y). User processes start out using 64k pages and get switched to 4k pages if they use any non-cacheable mappings. With this, we use 64k pages for the vmalloc region and 4k pages for the imalloc region. If anything creates a non-cacheable mapping in the vmalloc region, the vmalloc region will get switched to 4k pages. I don't know of any driver other than the DRM that would do this, though, and these machines don't have AGP. When a region gets switched from 64k pages to 4k pages, we do not have to clear out all the 64k HPTEs from the hash table immediately. We use the _PAGE_COMBO bit in the Linux PTE to indicate whether the page was hashed in as a 64k page or a set of 4k pages. If hash_page is trying to insert a 4k page for a Linux PTE and it sees that it has already been inserted as a 64k page, it first invalidates the 64k HPTE before inserting the 4k HPTE. The hash invalidation routines also use the _PAGE_COMBO bit, to determine whether to look for a 64k HPTE or a set of 4k HPTEs to remove. With those two changes, we can tolerate a mix of 4k and 64k HPTEs in the hash table, and they will all get removed when the address space is torn down.

The rest of the MSI functions are superfluous for what is needed at this time. Many of which can have machdep calls added as needed. Ben and Michael Ellerman are looking into rewrite the MSI layer to be more generic. However, in the meantime this works as a interim solution.

The firmware of these machines returns -1 and 1 respectively when getprop is called for the bootargs property of /chosen, causing Linux to ignore its builtin command line in favor of a null string. This patch makes Linux use its builtin command line if getprop returns an error or a null string.

The first change adds a bit indicating that 802.11h rules are to be applied to a channel. As discussed earlier in this list, a single bit is unlikely to be sufficient; however, at this time I have been unable to find any regulations implementing differences between 802.11a and 802.11h other than DFS, radar detection and passive scanning. A single bit is thus sufficient to convey to the driver that these rules should be obeyed. The second change adds comments to the freq and max_power fields of struct ieee80211_channel to indicate the units that are used. Signed-Off-By: Larry Finger Signed-off-by: John W.

This README will help you +understand the configuration data and give you some guidance for +adding support for other panels if you wish. + + +lcd-panels.h +------------ + +There is no way, at present, to detect which panel is attached to the +system at runtime. Thus the kernel configuration is static. The file +arch/arm/mach-ld7a40x/lcd-panels.h (or similar) defines all of the +panel specific parameters. + +It should be possible for this data to be shared among several device +families. The current layout may be insufficiently general, but it is +amenable to improvement. + + +PIXEL_CLOCK +----------- + +The panel data sheets will give a range of acceptable pixel clocks. +The fundamental LCDCLK input frequency is divided down by a PCD +constant in field '.tim2'. It may happen that it is impossible to set +the pixel clock within this range. A clock which is too slow will +tend to flicker. For the highest quality image, set the clock as high +as possible. + + +MARGINS +------- + +These values may be difficult to glean from the panel data sheet. In +the case of the Sharp panels, the upper margin is explicitly called +out as a specific number of lines from the top of the frame. The +other values may not matter as much as the panels tend to +automatically center the image. + + +Sync Sense +---------- + +The sense of the hsync and vsync pulses may be called out in the data +sheet. On one panel, the sense of these pulses determine the height +of the visible region on the panel. Most of the Sharp panels use +negative sense sync pulses set by the TIM2_IHS and TIM2_IVS bits in +'.tim2'. + + +Pel Layout +---------- + +The Sharp color TFT panels are all configured for 16 bit direct color +modes. The amba-lcd driver sets the pel mode to 565 for 5 bits of +each red and blue and 6 bits of green. -- cgit v1.2.3 From a5a503038e71a6b7d4bd9e596ac13087274e60c7 Mon Sep 17 00:00:00 2001 From: Vitaly Wool Date: Tue, 16 May 2006 11:54:36 +0100 Subject: [ARM] 3465/1: [1/3] Support for Philips PNX4008 platform: headers Patch from Vitaly Wool This patch adds kernel headers for PNX4008 ARM platform. It's basically the same as the previos one, but with the rmk's comments taken into account.

Thumb sys_syscall broken Patch from Paul Brook The old-abi sys_syscall syscall is broken when called from Thumb mode. It assumes the syscall number is an Arm syscall number (ie. starts from __NR_OABI_SYSCALL_BASE). In thumb mode syscall numbers start from zero. The patch below fixes this by clearing the nigh bits of the syscall number instead of inverting them. Technically this means we accept some invalid syscall numbers, but I can't see how that could be a problem. The two sets of numbers far apart that unimplemented syscalls should still be rejected.

As such, we should not pass the log2 block size to host drivers, but instead pass the byte size. However, ARM MMCI can only work with log2 block size, so continue to pass both the log2 block size and byte block size. This means that for the moment, the byte block size must remain a power of two, but this is the first stage of removing this restriction for other hosts.

Replace calls to DBG() with pr_debug(). 2. 'host' can never be null, so don't bother checking for that case. 3. Remove SA_SAMPLE_RANDOM from request_irq(). [Patch from Matt Mackall] 4. clk_get() doesn't return NULL on error - need to test returned value with IS_ERR(). 5. Free resources if clk_get() or request_irq() fails.

The changes include: 1. USB Host device renamed to "at91_ohci" since the driver is also usable on the AT91SAM9261 processor. 2. Enabling multidrive on the USB Device's pullup pin should not be done for all boards. Moved into board-specific files. [Patch from David Brownell] 3. Move enabling of PCMCIA/Compact Flash pins out of the driver. 4. Added SPI device and resources. 5. Added Watchdog device and resources. [Patch from David Brownell] 6. Added UART device and resources. 7. The simple devices (watchdog, rtc, i2c) are now automatically registered and don't have to be registered separately in each board-specific file.

Andrew Victor Date: Mon, 19 Jun 2006 17:26:23 +0100 Subject: [ARM] 3588/1: AT91RM9200 CSB337/637 board update Patch from Andrew Victor This patch updates the support for the Cogent CSB337 and CSB637 boards. The changes include: 1. Use the new at91_uart_config structure and device registration functions for the UARTs. 2. Registration of I2C and SPI platform devices. 3. The CSB337 board uses PB0 & PB1 (and not PB2) for the LEDs.

Changes include: 1. Conversion to a platform_driver. [Ivan Kokshaysky] 2. Replaced all references to AT91RM9200 with AT91. This driver can now also be used for the AT91SAM9216. 3. Allow TIOCM_LOOP to configure local loopback mode. 4. Cleaned up the 'read_status_mask' usage and interrupt handler code. [Chip Coldwell] 5. Suspend/resume support.

It appears that this is an unintended consequence of relinquinshing the queue lock while transmitting. That in turn is needed for devices that spend a lot of time in their transmit routine. There are no advantages to be had as devices with queues are inherently single-threaded (the loopback device is not but then it doesn't have a queue). Even if you were to add a queue to a parallel virtual device (e.g., bolt a tbf filter in front of an ipip tunnel device), you would still want to process the queue in sequence to ensure that the packets are ordered correctly. The solution here is to steal a bit from net_device to prevent this. BTW, as qdisc_restart is no longer used by anyone as a module inside the kernel (IIRC it used to with netif_wake_queue), I have not exported the new __qdisc_run function.

Miller" Date: Tue, 20 Jun 2006 01:21:29 -0700 Subject: [SPARC]: Kill __irq_itoa(). This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S.

Miller" Date: Tue, 20 Jun 2006 01:22:35 -0700 Subject: [SPARC64]: Virtualize IRQ numbers. Inspired by PowerPC XICS interrupt support code. All IRQs are virtualized in order to keep NR_IRQS from needing to be too large. Interrupts on sparc64 are arbitrary 11-bit values, but we don't need to define NR_IRQS to 2048 if we virtualize the IRQs. As PCI and SBUS controller drivers build device IRQs, we divy out virtual IRQ numbers incrementally starting at 1. Zero is a special virtual IRQ used for the timer interrupt. So device drivers all see virtual IRQs, and all the normal interfaces such as request_irq(), enable_irq(), etc. translate that into a real IRQ number in order to configure the IRQ. At this point knowledge of the struct ino_bucket is almost entirely contained within arch/sparc64/kernel/irq.c There are a few small bits in the PCI controller drivers that need to be swept away before we can remove ino_bucket's definition out of asm-sparc64/irq.h and privately into kernel/irq.c Signed-off-by: David S.

Miller" Date: Tue, 20 Jun 2006 01:23:32 -0700 Subject: [SPARC64]: Move over to GENERIC_HARDIRQS. This is the long overdue conversion of sparc64 over to the generic IRQ layer. The kernel image is slightly larger, but the BSS is ~60K smaller due to the reduced size of struct ino_bucket. A lot of IRQ implementation details, including ino_bucket, were moved out of asm-sparc64/irq.h and are now private to arch/sparc64/kernel/irq.c, and most of the code in irq.c totally disappeared. One thing that's different at the moment is IRQ distribution, we do it at enable_irq() time. If the cpu mask is ALL then we round-robin using a global rotating cpu counter, else we pick the first cpu in the mask to support single cpu targetting. This is similar to what powerpc's XICS IRQ support code does. This works fine on my UP SB1000, and the SMP build goes fine and runs on that machine, but lots of testing on different setups is needed.

Solution: create skb and put them into a queue instead of sending; once we are done, send what we've got on the list.

To summarize, I made the following changes: 1. Changed sys_msgctl() and semctl_down() so that an IPC_SET_PERM record is emitted in the failure case as well as the success case. This matches the behavior in sys_shmctl(). I could simplify the code in sys_msgctl() and semctl_down() slightly but it would mean that in some error cases we could get an IPC_SET_PERM record without an IPC record and that seemed odd. 2. No change to the IPC record type, given no feedback on the backward compatibility question. 3. Removed the qbytes field from the IPC record. It wasn't being set and when audit_ipc_obj() is called from ipcperms(), the information isn't available. If we want the information in the IPC record, more extensive changes will be necessary. Since it only applies to message queues and it isn't really permission related, it doesn't seem worth it. 4. Removed the obj field from the IPC_SET_PERM record. This means that the kern_ipc_perm argument is no longer needed. 5. Removed the spaces and renamed the IPC_SET_PERM field names. Replaced iuid and igid fields with ouid and ogid in the IPC record. I tested this with the lspp.22 kernel on an x86_64 box. I believe it applies cleanly on the latest kernel. -- ljk Signed-off-by: Linda Knippers Signed-off-by: Al Viro --- include/linux/audit.h | 4 ++-- ipc/msg.c | 9 +++++---- ipc/sem.c | 8 +++++--- ipc/shm.c | 2 +- kernel/auditsc.c | 22 +++++----------------- 5 files changed, 18 insertions(+), 27 deletions(-) diff --git a/include/linux/audit.h b/include/linux/audit.h index 8f6424f2b604..da5f521be04b 100644 --- a/include/linux/audit.h +++ b/include/linux/audit.h @@ -325,7 +325,7 @@ extern void auditsc_get_stamp(struct audit_context *ctx, extern int audit_set_loginuid(struct task_struct *task, uid_t loginuid);

Wilson" Date: Wed, 24 May 2006 16:09:55 -0500 Subject: [PATCH] Audit of POSIX Message Queue Syscalls v.2 This patch adds audit support to POSIX message queues. It applies cleanly to the lspp.b15 branch of Al Viro's git tree. There are new auxiliary data structures, and collection and emission routines in kernel/auditsc.c. New hooks in ipc/mqueue.c collect arguments from the syscalls. I tested the patch by building the examples from the POSIX MQ library tarball. Build them -lrt, not against the old MQ library in the tarball. Here's the URL: http://www.geocities.com/wronski12/posix_ipc/libmqueue-4.41.tar.gz Do auditctl -a exit,always -S for mq_open, mq_timedsend, mq_timedreceive, mq_notify, mq_getsetattr. mq_unlink has no new hooks. Please see the corresponding userspace patch to get correct output from auditd for the new record types.

When audit's inotify event handler is called, it updates any affected rules based on the filesystem event. If the parent directory is renamed, removed, or its filesystem is unmounted, audit removes all rules referencing that inotify watch. To keep things simple, this implementation limits location-based auditing to the directory entries in an existing directory. Given a path-based rule for /foo/bar/passwd, the following table applies: passwd modified -- audit event logged passwd replaced -- audit event logged, rules list updated bar renamed -- rule removed foo renamed -- untracked, meaning that the rule now applies to the new location Audit users typically want to have many rules referencing filesystem objects, which can significantly impact filtering performance. This patch also adds an inode-number-based rule hash to mitigate this situation. The patch is relative to the audit git tree: http://kernel.org/git/?p=linux/kernel/git/viro/audit-current.git;a=summary and uses the inotify kernel API: http://lkml.org/lkml/2006/6/1/145 Signed-off-by: Amy Griffis Signed-off-by: Al Viro --- include/linux/audit.h | 1 + init/Kconfig | 3 +- kernel/audit.c | 41 ++- kernel/audit.h | 38 ++- kernel/auditfilter.c | 785 +++++++++++++++++++++++++++++++++++++++++++++++--- kernel/auditsc.c | 124 +++++--- 6 files changed, 903 insertions(+), 89 deletions(-) diff --git a/include/linux/audit.h b/include/linux/audit.h index 7c8780b150e6..c78327507f4e 100644 --- a/include/linux/audit.h +++ b/include/linux/audit.h @@ -165,6 +165,7 @@ #define AUDIT_INODE 102 #define AUDIT_EXIT 103 #define AUDIT_SUCCESS 104 /* exit >= 0; value ignored */ +#define AUDIT_WATCH 105 #define AUDIT_ARG0 200 #define AUDIT_ARG1 (AUDIT_ARG0+1) diff --git a/init/Kconfig b/init/Kconfig index 3b36a1d53656..c4d0fa655d5d 100644 --- a/init/Kconfig +++ b/init/Kconfig @@ -182,7 +182,8 @@ config AUDITSYSCALL help Enable low-overhead system-call auditing infrastructure that can be used independently or with another kernel subsystem, - such as SELinux. + such as SELinux.

It will support suspend-to-RAM and standby modes. The suspend-to-RAM functionality is not 100% complete. The code that needs to be execute from the internal SRAM to restore the system is outstanding. For now we just fall through to Standby mode. The AT91-specific at91_suspend_entering_slow_clock() function will eventually be replaced by clk_must_disable() once that functionality is added to mainline clock API. Patch from David Brownell.

It doesn't yet handle some of the RAS interrupts (the ones described in iic_is/iic_irr), I'm still working on a proper way to expose these. They are essentially a cascaded controller by themselves (sic !) though I may just handle them locally to the iic driver. I need also to sync with David Erb on the way he hooked in the performance monitor interrupt. So that's all for 2.6.17 and I'll do more work on that with my rework of the powerpc interrupt layer that I'm hacking on at the moment.

This patch hardcodes the data structures to a 64k page alignment, which also guarantees 4k alignment but unfortunately wastes 60k of memory per SPU context that is created in the running system. We will follow up on this with another patch to reduce that overhead or maybe redo the context save/restore logic to do this part entirely different, but for now it should make experimental systems work with either page size.

ddf5f75a16b3e7460ffee881795aa168dffcd0cf Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 20 Jun 2006 02:30:33 +0200 Subject: [POWERPC] disable floating point exceptions for init Floating point exceptions should not be enabled by default, as this setting impacts the performance on some CPUs, in particular the Cell BE. Since the bits are inherited from parent processes, the place to change the default is the thread struct used for init. glibc sets this up correctly per thread in its fesetenv function, so user space should not be impacted by this setting. None of the other common libc implementations (uClibc, dietlibc, newlib, klibc) has support for fp exceptions, so they are unlikely to be hit by this either. There is a small risk that somebody wrote their own application that manually sets the fpscr bits instead of calling fesetenv, without changing the MSR bits as well. Those programs will break with this change. It probably makes sense to change glibc in the future to be more clever about FE bits, so that when running on a CPU where this is expensive, it disables exceptions ASAP, while it keeps them enabled on CPUs where running with exceptions on is cheaper than changing the state often.

The reason is that the generic mdelay(n) does n delays of 1 millisecond each. However, with 1/10 of a processor, we only get a one-millisecond timeslice every 10ms. Thus each 1 millisecond delay loop ends up taking 10ms elapsed time. The solution is just to use the PPC64 udelay function, which uses the timebase to ensure that the delay is based on elapsed time rather than how much processing time the partition has been given. (Yes, the generic mdelay uses the PPC64 udelay, but the problem is that the start time gets reset every millisecond, and each time it gets reset we lose another 9ms.)

Peter Anvin" Date: Tue, 18 Apr 2006 17:19:52 -0700 Subject: [PATCH] PCI: Ignore pre-set 64-bit BARs on 32-bit platforms [pci] Ignore pre-set 64-bit BARs on 32-bit platforms Currently, Linux always rejects a device which has a pre-set 64-bit address on a 32-bit platform. On systems which do not do PCI initialization in firmware, this causes some devices which don't correctly power up with all BARs zero to fail. This patch makes the kernel automatically zero out such an address (thus treating it as if it had not been set at all, meaning it will assign an address if necessary).

This can happen either if the firmware assigns 64-bit addresses; additionally, some cards have been found "in the wild" which do not come out of reset with all the BAR registers set to zero. Unfortunately, the patch that implemented this tested the low part of the address instead of the high part of the address. This patch fixes that. Signed-off-by: Bjorn Helgaas Signed-off-by: H.

The FPGA may be access by DSPs in the system and those DSPs expect the FPGA at a fixed PCI address.

When read it shows the "enabled-ness" of the device, but you can write a "0" into it to disable a device, and a "1" to enable it. This later is needed for X and other cases where userspace wants to enable the BARs on a device (typical example: to run the video bios on a secundary head). Right now X does all this "by hand" via bitbanging, that's just evil. This allows X to no longer do that but to just let the kernel do this.

This patch disables resource decode for the PCI device being disabled, making it symmetric with the enable call. I saw this while doing something else, not because of a problem report.

After some good feedback on the PCI Parity detection code and interface (http://www.ussg.iu.edu/hypermail/linux/kernel/0603.1/0897.html) this patch ADDs an new attribute to the pci_dev structure: Namely the 'broken_parity_status' bit. When set this indicates that the respective hardware generates false positives of Parity errors. The EDAC "blacklist" solution was inferior and will be removed in a future patch. Also in this patch is a PCI quirk.c entry for an Infiniband PCI-X card which generates false positive parity errors. I am requesting comments on this AND on the possibility of a exposing this 'broken_parity_status' bit to userland via the PCI device sysfs directory for devices. This access would allow for enabling of this feature on new devices and for old devices that have their drivers updated. (SLES 9 SP3 did this on an ATI motherboard video device). There is a need to update such a PCI attribute between kernel releases. This patch just adds a storage place for the attribute and a quirk entry for a known bad PCI device.

MSI was enabled for the device in the main kernel when it crashed. The e1000 driver tried to enable MSI on the kexec kernel, but the code bailed early when it found that MSI was already enabled in the hardware, even though the software state was not properly set up in the kexec'd kernel. This patch fixes the problem by moving the early return to after making sure that the software state is properly initialized.

In another hand, suspend/resume needs disable msi mode, as device should stop working completely. This patch try to workaround this issue.

It simply adds another exclusion (which already includes classless devices and host bridges) to the function pbus_assign_resources_sorted so that it will not move the ioapic.

All interrupt handlers should be registered with SA_SHIRQ and use the devid to map IRQs to devices (remember that all PCI interrupts are shared). -- cgit v1.2.3 From d71374dafbba7ec3f67371d3b7e9f6310a588808 Mon Sep 17 00:00:00 2001 From: Zhang Yanmin Date: Fri, 2 Jun 2006 12:35:43 +0800 Subject: [PATCH] PCI: fix race with pci_walk_bus and pci_destroy_dev pci_walk_bus has a race with pci_destroy_dev. When cb is called in pci_walk_bus, pci_destroy_dev might unlink the dev pointed by next. Later on in the next loop, pointer next becomes NULL and cause kernel panic. Below patch against 2.6.17-rc4 fixes it by changing pci_bus_lock (spin_lock) to pci_bus_sem (rw_semaphore).

Reading this attribute a userland program can determine if PCI device provides false positives (value of 1) in its generation of PCI Parity status, or not (value of 0). As PCI devices are found to be 'bad' in this regard, userland programs can also set the appropriate value (root access only) of a faulty device. This per device information will be used in the EDAC PCI Parity scanner code in a future patch once this interface becomes available.

According to Petr Vandrovec: ... "What is important (and checked) is address of MMCONFIG reported by MCFG table... Unfortunately code does not bother with printing that address :-( "Another problem is that code has hardcoded that MMCONFIG area is 256MB large. Unfortunately for the code PCI specification allows any power of two between 2MB and 256MB if vendor knows that such amount of busses (from 2 to 128) will be sufficient for system. With notebook it is quite possible that not full 8 bits are implemented for MMCONFIG bus number." So here is a patch. Unfortunately my system still fails the test because it doesn't reserve any part of the MMCONFIG area, but this may fix others. Booted on x86_64, only compiled on i386. x86_64 still remaps the max area (256MB) even though only 2MB is checked... but 2.6.16 had no check at all so it is still better. PCI: reduce size of x86 MMCONFIG reserved area check 1. Print the address of the MMCONFIG area when the test for that area being reserved fails. 2. Only check if the first 2MB is reserved, as that is the minimum.

In the course of that, I suggested a seperate ISA bus might be best; Russell King agreed and suggested this bus could use the .match() method for the actual device discovery. The attached does this. For this old non (generically) discoverable ISA hardware only the driver itself can do discovery so as a difference with the platform_bus, this isa_bus also distributes match() up to the driver. As another difference: these devices only exist in the driver model due to the driver creating them because it might want to drive them, meaning that all device creation has been made internal as well. The usage model this provides is nice, and has been acked from the ALSA side by Takashi Iwai and Jaroslav Kysela. The ALSA driver module_init's now (for oldisa-only drivers) become: static int __init alsa_card_foo_init(void) { return isa_register_driver(&snd_foo_isa_driver, SNDRV_CARDS); } static void __exit alsa_card_foo_exit(void) { isa_unregister_driver(&snd_foo_isa_driver); } Quite like the other bus models therefore. This removes a lot of duplicated init code from the ALSA ISA drivers. The passed in isa_driver struct is the regular driver struct embedding a struct device_driver, the normal probe/remove/shutdown/suspend/resume callbacks, and as indicated that .match callback. The "SNDRV_CARDS" you see being passed in is a "unsigned int ndev" parameter, indicating how many devices to create and call our methods with. The platform_driver callbacks are called with a platform_device param; the isa_driver callbacks are being called with a "struct device *dev, unsigned int id" pair directly -- with the device creation completely internal to the bus it's much cleaner to not leak isa_dev's by passing them in at all. The id is the only thing we ever want other then the struct device * anyways, and it makes for nicer code in the callbacks as well. With this additional .match() callback ISA drivers have all options. If ALSA would want to keep the old non-load behaviour, it could stick all of the old .probe in .match, which would only keep them registered after everything was found to be present and accounted for. If it wanted the behaviour of always loading as it inadvertently did for a bit after the changeover to platform devices, it could just not provide a .match() and do everything in .probe() as before. If it, as Takashi Iwai already suggested earlier as a way of following the model from saner buses more closely, wants to load when a later bind could conceivably succeed, it could use .match() for the prerequisites (such as checking the user wants the card enabled and that port/irq/dma values have been passed in) and .probe() for everything else. This is the nicest model. To the code... This exports only two functions; isa_{,un}register_driver(). isa_register_driver() register's the struct device_driver, and then loops over the passed in ndev creating devices and registering them. This causes the bus match method to be called for them, which is: int isa_bus_match(struct device *dev, struct device_driver *driver) { struct isa_driver *isa_driver = to_isa_driver(driver); if (dev->platform_data == isa_driver) { if (!isa_driver->match || isa_driver->match(dev, to_isa_dev(dev)->id)) return 1; dev->platform_data = NULL; } return 0; } The first thing this does is check if this device is in fact one of this driver's devices by seeing if the device's platform_data pointer is set to this driver. Platform devices compare strings, but we don't need to do that with everything being internal, so isa_register_driver() abuses dev->platform_data as a isa_driver pointer which we can then check here. I believe platform_data is available for this, but if rather not, moving the isa_driver pointer to the private struct isa_dev is ofcourse fine as well. Then, if the the driver did not provide a .match, it matches. If it did, the driver match() method is called to determine a match. If it did _not_ match, dev->platform_data is reset to indicate this to isa_register_driver which can then unregister the device again. If during all this, there's any error, or no devices matched at all everything is backed out again and the error, or -ENODEV, is returned. isa_unregister_driver() just unregisters the matched devices and the driver itself. More global points/questions... - I'm introducing include/linux/isa.h. It was available but is ofcourse a somewhat generic name. Moving more isa stuff over to it in time is ofcourse fine, so can I have it please? :) - I'm using device_initcall() and added the isa.o (dependent on CONFIG_ISA) after the base driver model things in the Makefile. Will this do, or I really need to stick it in drivers/base/init.c, inside #ifdef CONFIG_ISA? It's working fine. Lastly -- I also looked, a bit, into integrating with PnP. "Old ISA" could be another pnp_protocol, but this does not seem to be a good match, largely due to the same reason platform_devices weren't -- the devices do not have a life of their own outside the driver, meaning the pnp_protocol {get,set}_resources callbacks would need to callback into driver -- which again means you first need to _have_ that driver. Even if there's clean way around that, you only end up inventing fake but valid-form PnP IDs and generally catering to the PnP layer without any practical advantages over this very simple isa_bus. The thing I also suggested earlier about the user echoing values into /sys to set up the hardware from userspace first is... well, cute, but a horrible idea from a user standpoint. Comments ofcourse appreciated. Hope it's okay. As said, the usage model is nice at least.

However it turns out that even though they don't actually switch power, they do ignore all events on a port until told to turn on the power! This problem has been reported by several users. This revised patch (as672b) makes the hub driver always try to turn on port power to all hubs, regardless of what the hub descriptor says. It also adds a comment explaining the need for this.

The scsi layer is now much more likely to pass down scatterlists instead of plain buffers. So you have to make sure that they're handled correctly. In one of the changes along the way, usbat_write_block and friends stopped obeying the srb->use_sg flag. Anyway, with the appended patch, and the one I'm putting in the next email, it all seems to work for the HP cd4e. Of course, someone's going to have to test it with the flash drives as well.... This patch teaches the usbat_{read,write}_block functions to obey the use_sg flag in the scsi-request.

Now that Peter Chubb's patch has simplified the detection of 99% of the HP CD writers out there, we have a much smaller range of hardware to work with on the shared device ID, so it should be possible to try some of the previous probe options again: we just need to find another tester with a USBAT2-based HP CD writer. This patch hardcodes the flash detection until someone comes along with one of these obscure CD drives. Note that these devices are extremely rare, so even if we can't ever find a decent probe method, at least we will be supporting almost all of the USBAT-based hardware out there.

When an HID event is then sent up to the input layer, it may then be discarded as irrelevant because the wrong capability bit is set. Further, the quirks for the Apple Mighty Mouse are not quite right: the horizontal scrolling needs its axis reversed, and the left and center buttons are transposed. Also, the mouse is labeled in the kernel with its earlier name (I think) of Apple PowerMouse. Steps to reproduce problem: Plug in an Apple Mighty Mouse. Note that horizontal scrolling doesn't work at all, and in fact doesn't generate any input events on /dev/input/eventN. Note also that pushing the middle button performs the right button action, and vice versa. Once you have the horizontal scrolling working, note that it is backward WRT both to vertical scrolling and to common sense. This patch maybe should be broken up, as it does address two problems. The transposed code in hidinput_configure_usage() probably creates bugs beyond just the Mighty Mouse. The rest of the patch renames POWERMOUSE to MIGHTYMOUSE everywhere (which I *believe* is correct), fixes the MIGHTYMOUSE quirk to swap the center and right mouse buttons, and adds a new quirk HID_QUIRK_INVERT_HWHEEL also assigned to the MIGHTYMOUSE with code in hidinput_hid_event() to implement it.

This won't cure all the problems since some devices don't support the boot protocol, but it's simple and easy and it should fix quite a few problems.

It keeps track of which endpoint queues have advanced, and when none have advanced for a sufficiently long time, FSBR is turned off. The next TD on each of the non-moving queues is modified to generate an interrupt on completion, so that FSBR can be re-enabled as soon as the hardware starts to make some progress.

The USB spec does not specify a strict limit on the size of an entire control transfer. It does, however, state that the data stage "follows the same protocol rules as bulk transfers." (USB 2, 8.5.3) The level of support for large control transfers in real host controllers varies, but it's important to support at least 4K transfers. Windows enforces a maximum control transfer size of 4K, so there exists some hardware that requires a full 4096 byte data stage. Without this patch, we fall short of that by 8 bytes on architectures with a 4K page size, and it becomes impossible to support such hardware with a user-space driver. Since any limit placed on control transfers by usbfs would be arbitrary, this patch replaces the PAGE_SIZE limit with the same arbitrary limit used by bulk transfers.

The new scheduler is selected by a config option, marked as EXPERIMENTAL so it can be tested (and more broadly reviewed) for a while until it seems safe to remove the original scheduler.

FSBR puts a noticeable load on a computer's PCI bus, so it should be disabled as soon as possible when it isn't in use. The patch leaves it running for only 10 ms after the last URB stops using it, on the theory that this should be long enough for a driver to submit another URB if it wants keep FSBR going.

It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus GmbH. It's based on a kernel 2.4 driver (cyport) by Marcus Maul which I ported to kernel 2.6 using sysfs. I intend to support more controllers of this family (and more features) as soon as I get hold of the required IDs etc. Please see the source code's header for more information.

Due to non-existent ordering between cpu_hotplug lock and dbs_mutex. Basically a race condition between cpu_down() and do_dbs_timer(). cpu_down() flow: * cpu_down() call for CPU 1 * Takes hot plug lock * Calls pre down notifier * cpufreq notifier handler calls cpufreq_driver_target() which takes cpu_hotplug lock again. OK as cpu_hotplug lock is recursive in same process context * CPU 1 goes down * Calls post down notifier * cpufreq notifier handler calls ondemand event stop which takes dbs_mutex So, cpu_hotplug lock is taken before dbs_mutex in this flow. do_dbs_timer is triggerred by a periodic timer event. It first takes dbs_mutex and then takes cpu_hotplug lock in cpufreq_driver_target(). Note the reverse order here compared to above. So, if this timer event happens at right moment during cpu_down, system will deadlok. Attached patch fixes the issue for both ondemand and conservative.

Unfortunately, the kernel hard-codes VFP instructions into the thread switch, which prevents this being run-time selectable. Solve this by introducing a notifier which things such as VFP can hook into to be informed of events which affect the VFP subsystem (eg, creation and destruction of threads, switches between threads.)

Moreover, we must not use the mrrc/mcrr versions since these will not be recognised by the assembler. We do not convert all instructions to the VFP-equivalent (yet) since binutils appears to barf on "fmrx rn, fpinst" and doesn't provide any other way (other than using the mrc equivalent) to encode this instruction - which is rather a problem when you have a VFP implementation which requires these instructions.

Use the 'smsc47m1' driver for fan monitoring and control. + +Voltages and temperatures are measured by an 8-bit ADC, the resolution +of the temperatures is 1 bit per degree C. +Voltages are scaled such that the nominal voltage corresponds to +192 counts, i.e. 3/4 of the full range. Thus the available range for +each voltage channel is 0V ... 255/192*(nominal voltage), the resolution +is 1 bit per (nominal voltage)/192. +Both voltage and temperature values are scaled by 1000, the sys files +show voltages in mV and temperatures in units of 0.001 degC. + +The +12V analog voltage input channel (in4_input) is multiplexed with +bit 4 of the encoded CPU voltage.

Contrary to the old aggregated "alarms" and "beeps" files, individual files constitute a standard way to access the status information, making it finally possible to implement a chip-independant hardware monitoring chip access library (once all drivers have been added this new interface, that is.) If future drivers need more individual files, the interface will be extended as needed at the same time these drivers are merged into the kernel tree.

Greer" Date: Tue, 25 Apr 2006 13:04:54 +0200 Subject: [PATCH] I2C: m41t00: Add support for the ST M41T81 and M41T85 This patch adds support for the ST m41t81 and m41t85 i2c rtc chips to the existing m41t00 driver. Since there is no way to reliably determine what type of rtc chip is in use, the chip type is passed in via platform_data. The i2c address and square wave frequency are passed in via platform_data as well. To accommodate the use of platform_data, a new header file include/linux/m41t00.h has been added. The m41t81 and m41t85 chips halt the updating of their time registers while they are being accessed. They resume when a stop condition exists on the i2c bus or when non-time related regs are accessed. To make the best use of that facility and to make more efficient use of the i2c bus, this patch replaces multiple i2c_smbus_xxx calls with a single i2c_transfer call. Signed-off-by: Mark A.

This patch updates the documentation and adds new IRQ mode check so we are sure not to miss any new "unusual" value. The PCI quirk for users of fix_hstcfg was not developed because the chipset lacks of subsystem ID registers and DMI is stated "To be filled". Impact to existing systems is minimal because the problem showed up on motherboards like 10 years back. On the other hand users of newer Serverworks and HT1000 systems won't be misleaded by the message suggesting to try the fix_hstcfg any more.

If you know the address of the chip, use a 'force' +parameter; this will put it into a more well-behaved state first. + +The driver implements three temperature sensors, five fan rotation speed +sensors, and ten voltage sensors. + +Temperatures are measured in degrees Celsius and measurement resolution is 1 +degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when +the temperature gets higher than the Overtemperature Shutdown value; it stays +on until the temperature falls below the Hysteresis value. + +Fan rotation speeds are reported in RPM (rotations per minute). An alarm is +triggered if the rotation speed has dropped below a programmable limit. Fan +readings can be divided by a programmable divider (1, 2, 4, 8 for fan 1/2/3 +and 1, 2, 4, 8, 16, 32, 64 or 128 for fan 4/5) to give the readings more +range or accuracy. + +Voltage sensors (also known as IN sensors) report their values in millivolts. +An alarm is triggered if the voltage has crossed a programmable minimum +or maximum limit. + +Alarms are provided as output from a "realtime status register".

The data I have got on uGuru have I assembled through +my weak knowledge in "backwards engineering". +And just for the record, you may have noticed uGuru isn't a chip developed by +Abit, as they claim it to be. It's realy just an microprocessor (uC) created by +Winbond (W83L950D).

I would like to express my thanks to Olle, this +document and the Linux driver could not have been written without his efforts. + +Note: because of the lack of specs only the sensors part of the uGuru is +described here and not the CPU / RAM / etc voltage & frequency control. + +Hans de Goede , 28-01-2006 + + +Detection +========= + +As far as known the uGuru is always placed at and using the (ISA) I/O-ports +0xE0 and 0xE4, so we don't have to scan any port-range, just check what the two +ports are holding for detection. We will refer to 0xE0 as CMD (command-port) +and 0xE4 as DATA because Abit refers to them with these names. + +If DATA holds 0x00 or 0x08 and CMD holds 0x00 or 0xAC an uGuru could be +present. We have to check for two different values at data-port, because +after a reboot uGuru will hold 0x00 here, but if the driver is removed and +later on attached again data-port will hold 0x08, more about this later. + +After wider testing of the Linux kernel driver some variants of the uGuru have +turned up which will hold 0x00 instead of 0xAC at the CMD port, thus we also +have to test CMD for two different values. On these uGuru's DATA will initally +hold 0x09 and will only hold 0x08 after reading CMD first, so CMD must be read +first! + +To be really sure an uGuru is present a test read of one or more register +sets should be done. + + +Reading / Writing +================= + +Addressing +---------- + +The uGuru has a number of different addressing levels. The first addressing +level we will call banks. A bank holds data for one or more sensors. The data +in a bank for a sensor is one or more bytes large. + +The number of bytes is fixed for a given bank, you should always read or write +that many bytes, reading / writing more will fail, the results when writing +less then the number of bytes for a given bank are undetermined. + +See below for all known bank addresses, numbers of sensors in that bank, +number of bytes data per sensor and contents/meaning of those bytes. + +Although both this document and the kernel driver have kept the sensor +terminoligy for the addressing within a bank this is not 100% correct, in +bank 0x24 for example the addressing within the bank selects a PWM output not +a sensor. + +Notice that some banks have both a read and a write address this is how the +uGuru determines if a read from or a write to the bank is taking place, thus +when reading you should always use the read address and when writing the +write address. The write address is always one (1) more then the read address. + + +uGuru ready +----------- + +Before you can read from or write to the uGuru you must first put the uGuru +in "ready" mode. + +To put the uGuru in ready mode first write 0x00 to DATA and then wait for DATA +to hold 0x09, DATA should read 0x09 within 250 read cycles. + +Next CMD _must_ be read and should hold 0xAC, usually CMD will hold 0xAC the +first read but sometimes it takes a while before CMD holds 0xAC and thus it +has to be read a number of times (max 50). + +After reading CMD, DATA should hold 0x08 which means that the uGuru is ready +for input. As above DATA will usually hold 0x08 the first read but not always. +This step can be skipped, but it is undetermined what happens if the uGuru has +not yet reported 0x08 at DATA and you proceed with writing a bank address. + + +Sending bank and sensor addresses to the uGuru +---------------------------------------------- + +First the uGuru must be in "ready" mode as described above, DATA should hold +0x08 indicating that the uGuru wants input, in this case the bank address. + +Next write the bank address to DATA. After the bank address has been written +wait for to DATA to hold 0x08 again indicating that it wants / is ready for +more input (max 250 reads). + +Once DATA holds 0x08 again write the sensor address to CMD. + + +Reading +------- + +First send the bank and sensor addresses as described above. +Then for each byte of data you want to read wait for DATA to hold 0x01 +which indicates that the uGuru is ready to be read (max 250 reads) and once +DATA holds 0x01 read the byte from CMD. + +Once all bytes have been read data will hold 0x09, but there is no reason to +test for this. Notice that the number of bytes is bank address dependent see +above and below. + +After completing a successfull read it is advised to put the uGuru back in +ready mode, so that it is ready for the next read / write cycle. This way +if your program / driver is unloaded and later loaded again the detection +algorithm described above will still work. + + + +Writing +------- + +First send the bank and sensor addresses as described above. +Then for each byte of data you want to write wait for DATA to hold 0x00 +which indicates that the uGuru is ready to be written (max 250 reads) and +once DATA holds 0x00 write the byte to CMD. + +Once all bytes have been written wait for DATA to hold 0x01 (max 250 reads) +don't ask why this is the way it is. + +Once DATA holds 0x01 read CMD it should hold 0xAC now. + +After completing a successfull write it is advised to put the uGuru back in +ready mode, so that it is ready for the next read / write cycle. This way +if your program / driver is unloaded and later loaded again the detection +algorithm described above will still work. + + +Gotchas +------- + +After wider testing of the Linux kernel driver some variants of the uGuru have +turned up which do not hold 0x08 at DATA within 250 reads after writing the +bank address. With these versions this happens quite frequent, using larger +timeouts doesn't help, they just go offline for a second or 2, doing some +internal callibration or whatever. Your code should be prepared to handle +this and in case of no response in this specific case just goto sleep for a +while and then retry. + + +Address Map +=========== + +Bank 0x20 Alarms (R) +-------------------- +This bank contains 0 sensors, iow the sensor address is ignored (but must be +written) just use 0.

The sensors for higher voltages however are +connected through a division circuit. The currently known division circuits +in use result in ranges of: 0-4361mV, 0-6248mV or 0-14510mV. 3.3 volt sources +use the 0-4361mV range, 5 volt the 0-6248mV and 12 volt the 0-14510mV . + +Temp sensors also use a linear scale, a reading of 0 corresponds with 0 degree +Celsius and a reading of 255 with a reading of 255 degrees Celsius. + + +Bank 0x22 Sensor Bank1 Settings (R) +Bank 0x23 Sensor Bank1 Settings (W) +----------------------------------- + +This bank contains 16 sensors, for each sensor it contains 3 bytes.

The LM70 temperature sensor chip supports a single temperature sensor. It communicates with a host processor (or microcontroller) via an SPI/Microwire Bus interface. Communication with the LM70 is simple: when the temperature is to be sensed, the driver accesses the LM70 using SPI communication: 16 SCLK cycles comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's complement digital temperature (sent via the SIO line), is available in the driver for interpretation.

Consisting of many modules, it currently replaces snd-powermac for all layout-id based machines and handles many more (for example new powerbooks and powermacs with digital output that previously couldn't be used at all). It also has support for all layout-IDs that Apple has (judging from their Info.plist file) but not all are tested. The driver currently has 2 known regressions over snd-powermac: * it doesn't handle powermac 7,2 and 7,3 * it doesn't have a DRC control on snapper-based machines I will fix those during the 2.6.18 development cycle.

You can + * see this when for example recording stereo in + * audacity, or recording the tas output via cable + * on another machine (use a sinus generator or so). + * I tried programming the BiQuads but couldn't + * make the delay work, maybe someone can read the + * datasheet and fix it.

OTOH, they all + * derive the clocks from common clocks, so it + * might just be possible. The framework allows the + * codec to refine the transfer_info items in the + * usable callback, so we can simply remove the + * rates the second instance is not using when it + * actually is in use. + * Maybe we'll need to make the sound busses have + * a 'clock group id' value so the codec can + * determine if the two outputs can be driven at + * the same time.

However this is ABI dependent and there is a mismatch with the way __NR_restart_syscall gets defined when the kernel is compiled for EABI. There is also a long standing bug in the thumb case since with OABI the __NR_restart_syscall value includes __NR_SYSCALL_BASE which should not be the case for Thumb syscalls.

Incorporate new flask headers from a modified version of the SELinux reference policy, with support for the new security class representing retained keys. Extend the "key_alloc" security hook with a task parameter representing the intended ownership context for the key being allocated. Attach security information to root's default keyrings within the SELinux initialization routine. Has passed David's testsuite.

The patch then uses this to maintain a reference on the task_struct of the process that calls request_key() for as long as the authorisation key remains unrevoked. This fixes a potential race between two processes both of which have assumed the authority to instantiate a key (one may have forked the other for example). The problem is that there's no locking around the check for revocation of the auth key and the use of the task_struct it points to, nor does the auth key keep a reference on the task_struct. Access to the "context" pointer in the auth key must thenceforth be done with the auth key semaphore held. The revocation method is called with the target key semaphore held write-locked and the search of the context process's keyrings is done with the auth key semaphore read-locked. The check for the revocation state of the auth key just prior to searching it is done after the auth key is read-locked for the search. This ensures that the auth key can't be revoked between the check and the search. The revocation notification method is added so that the context task_struct can be released as soon as instantiation happens rather than waiting for the auth key to be destroyed, thus avoiding the unnecessary pinning of the requesting process.

The steal_locks() function has an effect on applications doing: clone(CLONE_FILES) /* in child */ lock execve lock POSIX locks acquired before execve (by "child", "parent" or any further task sharing files_struct) will after the execve be owned exclusively by "child". According to Chris Wright some LSB/LTP kind of suite triggers without the stealing behavior, but there's no known real-world application that would also fail. Apps using NPTL are not affected, since all other threads are killed before execve. Apps using LinuxThreads are only affected if they - have multiple threads during exec (LinuxThreads doesn't kill other threads, the app may do it with pthread_kill_other_threads_np()) - rely on POSIX locks being inherited across exec Both conditions are documented, but not their interaction. Apps using clone() natively are affected if they - use clone(CLONE_FILES) - rely on POSIX locks being inherited across exec The above scenarios are unlikely, but possible. If the patch is vetoed, there's a plan B, that involves mostly keeping the weird stealing semantics, but changing the way lock ownership is handled so that network and local filesystems work consistently. That would add more complexity though, so this solution seems to be preferred by most people.

If it does, then it will call in to iput on the inode while the dentry is no longer able to be found by the umounting process. If iput takes a while, generic_shutdown_super could get all the way though shrink_dcache_parent and shrink_dcache_anon and invalidate_inodes without ever waiting on this particular inode. Eventually the superblock gets freed anyway and if the iput tried to touch it (which some filesystems certainly do), it will lose. The promised "Self-destruct in 5 seconds" doesn't lead to a nice day. The race is closed by holding s_umount while calling prune_one_dentry on someone else's dentry. As a down_read_trylock is used, shrink_dcache_memory will no longer try to prune the dentry of a filesystem that is being unmounted, and unmount will not be able to start until any such active prune_one_dentry completes. This requires that prune_dcache *knows* which filesystem (if any) it is doing the prune on behalf of so that it can be careful of other filesystems. shrink_dcache_memory isn't called it on behalf of any filesystem, and so is careful of everything. shrink_dcache_anon is now passed a super_block rather than the s_anon list out of the superblock, so it can get the s_anon list itself, and can pass the superblock down to prune_dcache. If prune_dcache finds a dentry that it cannot free, it leaves it where it is (at the tail of the list) and exits, on the assumption that some other thread will be removing that dentry soon. To try to make sure that some work gets done, a limited number of dnetries which are untouchable are skipped over while choosing the dentry to work on.

It makes sense to do this to vga_vram_base, because we're going to access memory between vga_vram_base and vga_vram_end. But it doesn't really make sense to map starting at vga_vram_end, because we aren't going to access memory starting there. On ia64, which always has to be different, ioremapping vga_vram_end gives you something completely incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being nonsense. As a bonus, we often know the size up front, so we can use ioremap() correctly, rather than giving it a zero size. Signed-off-by: Bjorn Helgaas Cc: "Antonino A.

The code in the kernel is about seven years old and I noticed that the external zlib library's inflate performance was significantly faster (~50%) than the code in the kernel on ARM (and faster again on x86_32). For comparison the newer deflate code is 20% slower on ARM and 50% slower on x86_32 but gives an approx 1% compression ratio improvement. I don't consider this to be an improvement for kernel use so have no plans to change the zlib_deflate code. Various changes have been made to the zlib code in the kernel, the most significant being the extra functions/flush option used by ppp_deflate. This update reimplements the features PPP needs to ensure it continues to work. This code has been tested on ARM under both JFFS2 (with zlib compression enabled) and ppp_deflate and on x86_32. JFFS2 sees an approx. 10% real world file read speed improvement. This patch also removes ZLIB_VERSION as it no longer has a correct value. We don't need version checks anyway as the kernel's module handling will take care of that for us.

The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available. So the only thing the flush parameter actually does is: + when flush is set to Z_FINISH, inflate() cannot return Z_OK.

The time it costs to decode the longer codes is - then traded against the time it takes to make longer tables. - - This results of this trade are in the variables lbits and dbits - below. lbits is the number of bits the first level table for literal/ - length codes can decode in one step, and dbits is the same thing for - the distance codes. Subsequent tables are also less than or equal to - those sizes. These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each. The literal/length table - codes 286 possible values, or in a flat code, a little over eight - bits. The distance table codes 30 possible values, or a little less - than five bits, flat. The optimum values for speed end up being - about one bit more than those, so lbits is 8+1 and dbits is 5+1. - The optimum values may differ though from machine to machine, and - possibly even between compilers.

EH used to exploit ehi->dev to do selective revalidation on a ATA bus. However, this is a bit hacky and makes it impossible to request selective revalidation from outside of EH or add another per-dev EH action. This patch adds per-dev EH action mask eh_info->dev_action[] and update EH to use this field for REVALIDATE. Note that per-dev actions can still be specified at port-level and it has the same effect of specifying the action for all devices on the port.

More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu Signed-off-by: David S.

In particular, the spin_unlock_wait call at the end has no effect on the xmit routine of lockless drivers. With a little bit of work, we can make it much more useful by providing the guarantee that when it returns, no more calls to the xmit routine of the underlying driver will be made. The idea is simple. There are two entry points in to the xmit routine. The first comes from dev_queue_xmit. That one is easily stopped by using synchronize_rcu. This works because we set the qdisc to noop_qdisc before the synchronize_rcu call. That in turn causes all subsequent packets sent to dev_queue_xmit to be dropped. The synchronize_rcu call also ensures all outstanding calls leave their critical section. The other entry point is from qdisc_run. Since we now have a bit that indicates whether it's running, all we have to do is to wait until the bit is off. I've removed the loop to wait for __LINK_STATE_SCHED to clear. This is useless because netif_wake_queue can cause it to be set again. It is also harmless because we've disarmed qdisc_run. I've also removed the spin_unlock_wait on xmit_lock because its only purpose of making sure that all outstanding xmit_lock holders have exited is also given by dev_watchdog_down.

So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu Signed-off-by: David S.

The idea is to tap into the potential savings of TSO without hardware support by postponing the allocation of segmented skb's until just before the entry point into the NIC driver. The same structure can be used to support software IPv6 TSO, as well as UFO and segmentation offload for other relevant protocols, e.g., DCCP. Signed-off-by: Herbert Xu Signed-off-by: David S.

This can happen when a NIC driver injects GSO packets into the stack which are then forwarded to another host. The primary application of this is going to be Xen where its backend driver may inject GSO packets into dom0. Of course this also can be used by other virtualisation schemes such as VMWare or UML since the tap device could be modified to inject GSO packets received through splice.

The filesystem is then required to manually set the superblock and root dentry pointers. For most filesystems, this should be done with simple_set_mnt() which will set the superblock pointer and then set the root dentry to the superblock's s_root (as per the old default behaviour). The get_sb() op now returns an integer as there's now no need to return the superblock pointer. This patch permits a superblock to be implicitly shared amongst several mount points, such as can be done with NFS to avoid potential inode aliasing. In such a case, simple_set_mnt() would not be called, and instead the mnt_root and mnt_sb would be set directly. The patch also makes the following changes: (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount pointer argument and return an integer, so most filesystems have to change very little. (*) If one of the convenience function is not used, then get_sb() should normally call simple_set_mnt() to instantiate the vfsmount. This will always return 0, and so can be tail-called from get_sb(). (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the dcache upon superblock destruction rather than shrink_dcache_anon(). This is required because the superblock may now have multiple trees that aren't actually bound to s_root, but that still need to be cleaned up. The currently called functions assume that the whole tree is rooted at s_root, and that anonymous dentries are not the roots of trees which results in dentries being left unculled. However, with the way NFS superblock sharing are currently set to be implemented, these assumptions are violated: the root of the filesystem is simply a dummy dentry and inode (the real inode for '/' may well be inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries with child trees. [*] Anonymous until discovered from another tree. (*) The documentation has been adjusted, including the additional bit of changing ext2_* into foo_* in the documentation.

This complements the get_sb() patch. That reduced the significance of sb->s_root, allowing NFS to place a fake root there. However, NFS does require a dentry to use as a target for the statfs operation. This permits the root in the vfsmount to be used instead. linux/mount.h has been added where necessary to make allyesconfig build successfully. Interest has also been expressed for use with the FUSE and XFS filesystems.

Where they do not we will incorrectly merge pages cross zone boundaries. This can lead to pages from the wrong zone being handed out. Originally the buddy allocator would check that buddies were in the same zone by referencing the zone start and end page frame numbers. This was removed as it became very expensive and the buddy allocator already made the assumption that zones boundaries were aligned. It is clear that not all configurations and architectures are honouring this alignment requirement. Therefore it seems safest to reintroduce support for non-aligned zone boundaries. This patch introduces a new check when considering a page a buddy it compares the zone_table index for the two pages and refuses to merge the pages where they do not match. The zone_table index is unique for each node/zone combination when FLATMEM/DISCONTIGMEM is enabled and for each section/zone combination when SPARSEMEM is enabled (a SPARSEMEM section is at least a MAX_ORDER size).

But MemoryHotplug can add new zone/pgdat. It must be updated. This patch modifies build_all_zonelists(). By this, build_all_zonelist() can reconfig pgdat's zonelists. To update them safety, this patch use stop_machine_run(). Other cpus don't touch among updating them by using it. In old version (V2 of node hotadd), kernel updated them after zone initialization. But present_page of its new zone is still 0, because online_page() is not called yet at this time. Build_zonelists() checks present_pages to find present zone. It was too early.

When sysctl vm.panic_on_oom = 1, the kernel panics intead of killing rogue processes. And if vm.panic_on_oom is 0 the kernel will do oom_kill() in the same way as it does today. Of course, the default value is 0 and only root can modifies it. In general, oom_killer works well and kill rogue processes. So the whole system can survive. But there are environments where panic is preferable rather than kill some processes.

This has been possible with util-linux-2.12b (via e2fsprogs 1.36 libblkid), and is used by at least FC3 and later. The kernel doesn't really care about this, but the space shouldn't accidentally be used by something else either. Also make the on-disk structures be fixed-size types, instead of "int", though I don't know of any architecture in use where an "int" isn't the same size as a "__u32" (all current kernel arches have it as "unsigned int").

This assumption often reserves (or lock down) a lot more pages then necessary if application maps at none zero file offset. libhugetlbfs is one example that requires proper reservation on shared mapping starts at none zero offset. This patch extends the reservation and hugetlb strict accounting to support any arbitrary pair of (offset, len), resulting a much more robust and accurate scheme. More importantly, it won't lock down any hugetlb pages outside file mapping.

Wysocki" Date: Fri, 23 Jun 2006 02:03:18 -0700 Subject: [PATCH] swsusp: rework memory shrinker MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rework the swsusp's memory shrinker in the following way: - Simplify balance_pgdat() by removing all of the swsusp-related code from it. - Make shrink_all_memory() use shrink_slab() and a new function shrink_all_zones() which calls shrink_active_list() and shrink_inactive_list() directly for each zone in a way that's optimized for suspend. In shrink_all_memory() we try to free exactly as many pages as the caller asks for, preferably in one shot, starting from easier targets.  If slab caches are huge, they are most likely to have enough pages to reclaim.  The inactive lists are next (the zones with more inactive pages go first) etc. Each time shrink_all_memory() attempts to shrink the active and inactive lists for each zone in 5 passes.  In the first pass, only the inactive lists are taken into consideration.  In the next two passes the active lists are also shrunk, but mapped pages are not reclaimed.  In the last two passes the active and inactive lists are shrunk and mapped pages are reclaimed as well. The aim of this is to alter the reclaim logic to choose the best pages to keep on resume and improve the responsiveness of the resumed system. Signed-off-by: Rafael J.

The purpose of this change is to eliminate the touching of the actual memory being allocated. Since the change modifies the interface, a change to the uncached allocator (arch/ia64/kernel/uncached.c) is also required. Both Andrey Volkov and Jes Sorenson have expressed a desire that the gen_pool allocator not write to the memory being managed.

On 64-bit machines this causes nearly 600 bytes to be used for every <= 4K file in pagecache. Re-introduce this feature, root tags stored in spare ->gfp_mask bits. Simplify radix_tree_delete's complex tag clearing arrangement (which would become even more complex) by just falling back to tag clearing functions (the pagecache radix-tree never uses this path anyway, so the icache savings will mean it's actually a speedup). On my 4GB G5, this saves 8MB RAM per kernel kernel source+object tree in pagecache. Pagecache lookup, insertion, and removal speed for small files will also be improved. This makes RCU radix tree harder, but it's worth it.

Sometimes it's useful to be able to differentiate between these two types of information. Add double-free detection to redzone verification when freeing an object. As explained by Manfred, when we are freeing an object, both redzones should be RED_ACTIVE. However, if both are RED_INACTIVE, we are trying to free an object that was already free'd.

Hence if 'index' is larger than the maxindex; the item _cannot_ be presen; it should also be a BUG. Also, this allows the following statement (assume a fresh tree): radix_tree_tag_set(root, 16, 1); to fail silently, but when preceded by: radix_tree_insert(root, 32, item); it would BUG, because the height has been extended by the insert.

Because we're currently overloading (start == 0 && end == 0) to mean "this is not a write-a-range request". To make all this sane, the patch changes range of writeback_control. So caller does: If it is calling ->writepages() to write pages, it sets range (range_start/end or range_cyclic) always. And if range_cyclic is true, ->writepages() thinks the range is cyclic, otherwise it just uses range_start and range_end. This patch does, - Add LLONG_MAX, LLONG_MIN, ULLONG_MAX to include/linux/kernel.h -1 is usually ok for range_end (type is long long). But, if someone did, range_end += val; range_end is "val - 1" u64val = range_end >> bits; u64val is "~(0ULL)" or something, they are wrong. So, this adds LLONG_MAX to avoid nasty things, and uses LLONG_MAX for range_end. - All callers of ->writepages() sets range_start/end or range_cyclic. - Fix updates of ->writeback_index. It seems already bit strange. If it starts at 0 and ended by check of nr_to_write, this last index may reduce chance to scan end of file. So, this updates ->writeback_index only if range_cyclic is true or whole-file is scanned. Signed-off-by: OGAWA Hirofumi Cc: Nathan Scott Cc: Anton Altaparmakov Cc: Steven French Cc: "Vladimir V.

The VM is modified to handle the migration entries. migration entries can only be encountered when the page they are pointing to is locked. This limits the number of places one has to fix. We also check in copy_pte_range and in mprotect_pte_range() for migration ptes. We check for migration ptes in do_swap_cache and call a function that will then wait on the page lock. This allows us to effectively stop all accesses to apge. Migration entries are created by try_to_unmap if called for migration and removed by local functions in migrate.c From: Hugh Dickins Several times while testing swapless page migration (I've no NUMA, just hacking it up to migrate recklessly while running load), I've hit the BUG_ON(!PageLocked(p)) in migration_entry_to_page. This comes from an orphaned migration entry, unrelated to the current correctly locked migration, but hit by remove_anon_migration_ptes as it checks an address in each vma of the anon_vma list. Such an orphan may be left behind if an earlier migration raced with fork: copy_one_pte can duplicate a migration entry from parent to child, after remove_anon_migration_ptes has checked the child vma, but before it has removed it from the parent vma. (If the process were later to fault on this orphaned entry, it would hit the same BUG from migration_entry_wait.) This could be fixed by locking anon_vma in copy_one_pte, but we'd rather not. There's no such problem with file pages, because vma_prio_tree_add adds child vma after parent vma, and the page table locking at each end is enough to serialize. Follow that example with anon_vma: add new vmas to the tail instead of the head. (There's no corresponding problem when inserting migration entries, because a missed pte will leave the page count and mapcount high, which is allowed for. And there's no corresponding problem when migrating via swap, because a leftover swap entry will be correctly faulted. But the swapless method has no refcounting of its entries.) From: Ingo Molnar pte_unmap_unlock() takes the pte pointer as an argument. From: Hugh Dickins Several times while testing swapless page migration, gcc has tried to exec a pointer instead of a string: smells like COW mappings are not being properly write-protected on fork. The protection in copy_one_pte looks very convincing, until at last you realize that the second arg to make_migration_entry is a boolean "write", and SWP_MIGRATION_READ is 30. Anyway, it's better done like in change_pte_range, using is_write_migration_entry and make_migration_entry_read. From: Hugh Dickins Remove unnecessary obfuscation from sys_swapon's range check on swap type, which blew up causing memory corruption once swapless migration made MAX_SWAPFILES no longer 2 ^ MAX_SWAPFILES_SHIFT.

Processes can therefore be migrated back and forth without loosing their connection to pagecache pages. Note that we implement the migration entries only for linear mappings. Nonlinear mappings still require the unmapping of the ptes for migration. And another writepage() ugliness shows up. writepage() can drop the page lock. Therefore we have to remove migration ptes before calling writepages() in order to avoid having migration entries point to unlocked pages.

Until now, we don't do any verification for this if CONFIG_DEBUG_SLAB is disabled. As suggested by Linus, add PageSlab check to page_to_cache() and page_to_slab() to verify pointers passed to kfree(). Also, move the stronger check from cache_free_debugcheck() to kmem_cache_free() to ensure the passed pointer actually belongs to the cache we're about to free the object. For page_to_cache() and page_to_slab(), the assertions should have virtually no extra cost (two instructions, no data cache pressure) and for kmem_cache_free() the overhead should be minimal.

This facility permits the filesystem or driver to: (*) Implement storage allocation/reservation on attempted write, and so to deal with problems such as ENOSPC more gracefully (perhaps by generating SIGBUS). (*) Delay making the page writable until the contents have been written to a backing cache. This is useful for NFS/AFS when using FS-Cache/CacheFS. It permits the filesystem to have some guarantee about the state of the cache. (*) Account and limit number of dirty pages. This is one piece of the puzzle needed to make shared writable mapping work safely in FUSE. Needed by cachefs (Or is it cachefiles? Or fscache? ). At least four other groups have stated an interest in it or a desire to use the functionality it provides: FUSE, OCFS2, NTFS and JFFS2. Also, things like EXT3 really ought to use it to deal with the case of shared-writable mmap encountering ENOSPC before we permit the page to be dirtied. From: Peter Zijlstra get_user_pages(.write=1, .force=1) can generate COW hits on read-only shared mappings, this patch traps those as mkpage_write candidates and fails to handle them the old way.

Extract two functions from migrate_pages() and get rid of the gotos. Plus we can just unconditionally set the locked bit on the new page since we are the only one holding a reference. Locking is to stop others from accessing the page once we establish references to the new page. Remove the list_del from move_to_lru in order to have finer control over list processing.

The function can be used to determine the location of pages and to move them onto the desired node. move_pages() returns status information for each page. long move_pages(pid, number_of_pages_to_move, addresses_of_pages[], nodes[] or NULL, status[], flags); The addresses of pages is an array of void * pointing to the pages to be moved. The nodes array contains the node numbers that the pages should be moved to. If a NULL is passed instead of an array then no pages are moved but the status array is updated. The status request may be used to determine the page state before issuing another move_pages() to move pages. The status array will contain the state of all individual page migration attempts when the function terminates. The status array is only valid if move_pages() completed successfullly. Possible page states in status[]: 0..MAX_NUMNODES The page is now on the indicated node. -ENOENT Page is not present -EACCES Page is mapped by multiple processes and can only be moved if MPOL_MF_MOVE_ALL is specified. -EPERM The page has been mlocked by a process/driver and cannot be moved. -EBUSY Page is busy and cannot be moved. Try again later. -EFAULT Invalid address (no VMA or zero page). -ENOMEM Unable to allocate memory on target node. -EIO Unable to write back page. The page must be written back in order to move it since the page is dirty and the filesystem does not provide a migration function that would allow the moving of dirty pages. -EINVAL A dirty page cannot be moved. The filesystem does not provide a migration function and has no ability to write back pages. The flags parameter indicates what types of pages to move: MPOL_MF_MOVE Move pages that are only mapped by the process. MPOL_MF_MOVE_ALL Also move pages that are mapped by multiple processes. Requires sufficient capabilities. Possible return codes from move_pages() -ENOENT No pages found that would require moving. All pages are either already on the target node, not present, had an invalid address or could not be moved because they were mapped by multiple processes. -EINVAL Flags other than MPOL_MF_MOVE(_ALL) specified or an attempt to migrate pages in a kernel thread. -EPERM MPOL_MF_MOVE_ALL specified without sufficient priviledges. or an attempt to move a process belonging to another user. -EACCES One of the target nodes is not allowed by the current cpuset. -ENODEV One of the target nodes is not online. -ESRCH Process does not exist. -E2BIG Too many pages to move. -ENOMEM Not enough memory to allocate control array. -EFAULT Parameters could not be accessed. A test program for move_pages() may be found with the patches on ftp.kernel.org:/pub/linux/kernel/people/christoph/pmig/patches-2.6.17-rc4-mm3 From: Christoph Lameter Detailed results for sys_move_pages() Pass a pointer to an integer to get_new_page() that may be used to indicate where the completion status of a migration operation should be placed. This allows sys_move_pags() to report back exactly what happened to each page. Wish there would be a better way to do this. Looks a bit hacky.

The existing code calculated the wrong address in the array since I used void to avoid having to specify a type. I now use the correct type "compat_uptr_t __user *" in the definition of the function in kernel/compat.c. However, I used __u32 in syscalls.h. Would have to include compat.h there in order to provide the same definition which would generate an ugly include situation. On both ia64 and x86_64 compat_uptr_t is u32.

Additionally, this adds back (in different places, and conditionalized upon a new module option) some messages removed by a previous patch.

Later on, when the irq is acked, kernel would calls move_native_irq=>desc->handler->set_affinity to change the irq affinity. However, every function pointed by hw_interrupt_type->set_affinity(unsigned int irq, cpumask_t cpumask) always changes irq_affinity[irq] to cpumask. Next time when recalling do_irq_balance, it has to do cpu_ands again with irq_affinity[selected_irq], but irq_affinity[selected_irq] already becomes one cpu selected by the first irq balance. 2) Function balance_irq in file arch/i386/kernel/io_apic.c has the same issue.

This patch makes the kernel warn about those partitions. We still permit these patitions to be used. Quoting Andries Brouwer : Case 1: The kernel is mistaken about the size of the disk. (There are commands to clip a disk to a certain capacity, there are jumpers to tell a disk that it should report a certain capacity etc. Usually this is because of BIOS bugs. In bad cases the machine will crash in the BIOS and hence fail to boot if the disk reports full capacity.) In such cases actually accessing the blocks of the partition may work fine, or may work fine after running an unclip utility. I wrote "setmax" some years ago precisely for this reason. Case 2: There was a messy partition table (maybe just a rounding error) but the actual filesystem on the partition is contained in the physical disk. Now using the filesystem goes without problem. Case 3: Both partition and filesystem extend beyond the end of the disk. In forensic or debugging situations one often uses a copy of the start of a disk. Now access beyond the end gives an expected I/O error.

It turns out the problem was that this losetup was only issuing the LOOP_SET_FD ioctl and not issuing a subsequent LOOP_SET_STATUS ioctl. This losetup didn't have any special status to set, so it left out the call. The deeper cause is that loop_set_fd sets the transfer function to NULL, which causes no transfer to happen lo_do_transfer. This patch fixes the problem by setting transfer to transfer_none in loop_set_fd.

It also causes performance problems when one does a lot of async io and then proceeds to sync it. Part of the io will go out as async, and the other part as sync. This causes a disconnect between the previously submitted io and the synced io. For io schedulers such as CFQ, this will cause us lost merges and suboptimal behaviour in scheduling. Remove PF_SYNCWRITE completely from the fsync/msync paths, and let the O_DIRECT path just directly indicate that the writes are sync by using WRITE_SYNC instead.

So the process 1 will work like with priority of process 2. I propose not to call cfq_init_prio_data() on io-priority change, but only mark queue as queue with changed prority. Every time when new request comes cfq-scheduler checks for this flag and atomaticaly changes priority of queue to new value.

Now it's true think/idle time. - Take advantage of TCQ/NCQ/queueing for seeky sync workloads, but keep it in control for sync and sequential (or close to) workloads. - Expire queues immediately and move on to other busy queues, if we are not going to idle after the current one finishes. - Don't rearm idle timer if there are no busy queues.

Miller" Date: Thu, 22 Jun 2006 00:01:56 -0700 Subject: [SPARC64]: Fix for Niagara memory corruption. On some sun4v systems, after netboot the ethernet controller and it's DMA mappings can be left active. The net result is that the kernel can end up using memory the ethernet controller will continue to DMA into, resulting in corruption. To deal with this, we are more careful about importing IOMMU translations which OBP has left in the IO-TLB. If the mapping maps into an area the firmware claimed was free and available memory for the kernel to use, we demap instead of import that IOMMU entry. This is going to cause the network chip to take a PCI master abort on the next DMA it attempts, if it has been left going like this. All tests show that this is handled properly by the PCI layer and the e1000 drivers. Signed-off-by: David S.

This fixes some more problems with flickering (bug #6637). drm may not be appropriate place for this, since doing that flush there might both be overkill and insufficient in some cases. However, it's hard to figure out when that flush is needed, so this has to suffice. There does not seem to be a performance penalty associated with it.

To support direct asynchronous scatter-gather writes, the write rescheduler in fs/nfs/direct.c must not depend on the I/O parameters in the controlling nfs_direct_req structure. iovecs can be somewhat arbitrarily complex, so there could be an unbounded amount of information to save for a rarely encountered requirement. Refactor the direct write rescheduler so it uses information from each nfs_write_data structure to reschedule writes, instead of caching that information in the controlling nfs_direct_req structure.

Instead of tracking one large page array per dreq/iocb, track pages per nfs_read/write_data, just like the cached I/O path does. An array for pages is already allocated for us by nfs_readdata_alloc() (and the write and commit equivalents). This is also required for adding support for vectored I/O to the NFS direct I/O path. The original reason to pin the user buffer and allocate all the NFS data structures before trying to schedule I/O was to ensure all needed resources are allocated on the client before starting to send requests. This reduces the chance that resource exhaustion on the client will cause a short read or write. On the other hand, for an application making very large application I/O requests, this means that it will be nearly impossible for the application to make forward progress on a resource-limited client. Thus, moving the buffer pinning functionality into the I/O scheduling loops should be good for scalability. The next patch will do the same for NFS data structure allocation.

This function adds support for stripping modules while they are being installed. CONFIG_DEBUG_KERNEL (which will probably become more popular as developers use kdump) causes the size of the installed modules to grow by a factor of 9 or so. Some kernel package systems solve this problem by stripping the debug information from /lib/modules after running "make modules_install", but that may not work for people who are installing directly into /lib/modules --- root partitions that were sized to handle 16 megs worth of modules may not be quite so happy with 145 megs of modules, so the "make modules_install" never succeeds. This patch allows such users to request modules_install to strip the modules as they are installed.

The dump format is the name of the type defined, followed by its definition (which is almost C): s#list_head struct list_head { s#list_head * next , * prev ; } The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef. The exported symbols do not define types, and thus do not have an x# prefix: nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 ) The symbol type defintion of a single file can be generated with: make fs/jbd/journal.symtypes If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that export symbols are generated. The single *.symtypes files can be combined into a single file after a kernel build with a script like the following: for f in $(find -name '*.symtypes' | sort); do f=${f#./} echo "/* ${f%.symtypes}.o */" cat $f echo done \ | sed -e '\:UNKNOWN:d' \ -e 's:[,;] }:}:g' \ -e 's:\([[({]\) :\1:g' \ -e 's: \([])},;]\):\1:g' \ -e 's: $::' \ $f \ | awk ' /^.#/ { if (defined[$1] == $0) { print $1 next } defined[$1] = $0 } { print } ' When the kernel ABI changes, diffing individual *.symtype files, or the combined files, against each other will show which symbol changes caused the ABI changes. This can save a tremendous amount of time.

As Al so eloquently points out, the patch is crap. The old code was fine, the new code was bogus. It never dereferenced a user pointer, the "->" operator was to an array member, which gives the _address_ of the member (in user space), not an actual dereference at all.

Some saa7115-based cards use a different crystal frequency and a different audio clock generation. Add a new VIDIOC_INT_S_CRYSTAL_FREQ command to be able to set these values. Also change the default APLL setting to 0. It makes no sense to have the audio clock independent from the video clock, this can lead to audio/video synchronization problems. Setting this to 0 is also consistent with the old saa7114.c source and the way the Hauppauge Windows driver sets it.

Previously you had to kinda look through dmesg and hope that it hadn't been dumped out of the buffer. This makes debugging a lot easier if the system has been up for a long time! This is done by adding an extra 'struct device *' parameter to dvb_register_adapter(). It will work with any kind of standard linux 'device'. Additionally, if someone has an embedded system which does things differently, they can simply supply 'NULL' and the behaviour will be as before - the link will simply not appear.

The driver populates these fields +with values for all the parameters required by the call. The driver overwrites +these fields with result values returned by the call. The API specifics may be +found in the fw-*-api.txt documents. + +The timeout value protects the card from a hung driver thread. If the driver +doesn't handle the completed call within the timeout specified, the firmware +will reset that mailbox. + +To make an API call, the driver iterates over each mailbox looking for the +first one available (bit 0 has been cleared). The driver sets that bit, fills +in the command enumerator, the timeout value and any required parameters. The +driver then sets the parameter ready bit (bit 1). The firmware scans the +mailboxes for pending commands, processes them, sets the result code, populates +the result value array with that call's return values and sets the call +complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results +and clear all the flags. If the driver does not perform this task within the +time set in the timeout register, the firmware will reset that mailbox. + +Event notifications are sent from the firmware to the host. The host tells the +firmware which events it is interested in via an API call. That call tells the +firmware which notification mailbox to use. The firmware signals the host via +an interrupt. Only the 16 Results fields are used, the Flags, Command, Return +value and Timeout words are not used. + diff --git a/Documentation/video4linux/cx2341x/fw-decoder-api.txt b/Documentation/video4linux/cx2341x/fw-decoder-api.txt new file mode 100644 index 000000000000..59193b6b5572 --- /dev/null +++ b/Documentation/video4linux/cx2341x/fw-decoder-api.txt @@ -0,0 +1,319 @@ +Decoder firmware API description +================================ + +Note: this API is part of the decoder firmware, so it's cx23415 only. + +------------------------------------------------------------------------------- + +Name CX2341X_DEC_PING_FW +Enum 0/0x00 +Description + This API call does nothing.

This means it has a DMA +engine to efficiently transfer large volumes of data between the card and main +memory without requiring help from a CPU. Like most hardware, it must operate +on contiguous physical memory. This is difficult to come by in large quantities +on virtual memory machines. + +Therefore, it also supports a technique called "scatter-gather". The card can +transfer multiple buffers in one operation. Instead of allocating one large +contiguous buffer, the driver can allocate several smaller buffers. + +In practice, I've seen the average transfer to be roughly 80K, but transfers +above 128K were not uncommon, particularly at startup. The 128K figure is +important, because that is the largest block that the kernel can normally +allocate. Even still, 128K blocks are hard to come by, so the driver writer is +urged to choose a smaller block size and learn the scatter-gather technique. + +Mailbox #10 is reserved for DMA transfer information. + +Flow +==== + +This section describes, in general, the order of events when handling DMA +transfers. Detailed information follows this section. + +- The card raises the Encoder interrupt. +- The driver reads the transfer type, offset and size from Mailbox #10. +- The driver constructs the scatter-gather array from enough free dma buffers + to cover the size. +- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call. +- The card raises the DMA Complete interrupt. +- The driver checks the DMA status register for any errors. +- The driver post-processes the newly transferred buffers. + +NOTE! It is possible that the Encoder and DMA Complete interrupts get raised +simultaneously. (End of the last, start of the next, etc.) + +Mailbox #10 +=========== + +The Flags, Command, Return Value and Timeout fields are ignored. + +Name: Mailbox #10 +Results[0]: Type: 0: MPEG. +Results[1]: Offset: The position relative to the card's memory space. +Results[2]: Size: The exact number of bytes to transfer. + +My speculation is that since the StartCapture API has a capture type of "RAW" +available, that the type field will have other values that correspond to YUV +and PCM data. + +Scatter-Gather Array +==================== + +The scatter-gather array is a contiguously allocated block of memory that +tells the card the source and destination of each data-block to transfer. +Card "addresses" are derived from the offset supplied by Mailbox #10. Host +addresses are the physical memory location of the target DMA buffer. + +Each S-G array element is a struct of three 32-bit words. The first word is +the source address, the second is the destination address. Both take up the +entire 32 bits. The lowest 16 bits of the third word is the transfer byte +count. The high-bit of the third word is the "last" flag. The last-flag tells +the card to raise the DMA_DONE interrupt. From hard personal experience, if +you forget to set this bit, the card will still "work" but the stream will +most likely get corrupted. + +The transfer count must be a multiple of 256. Therefore, the driver will need +to track how much data in the target buffer is valid and deal with it +accordingly. + +Array Element: + +- 32-bit Source Address +- 32-bit Destination Address +- 16-bit reserved (high bit is the last flag) +- 16-bit byte count + +DMA Transfer Status +=================== + +Register 0x0004 holds the DMA Transfer Status: + +Bit +4 Scatter-Gather array error +3 DMA write error +2 DMA read error +1 write completed +0 read completed diff --git a/Documentation/video4linux/cx2341x/fw-encoder-api.txt b/Documentation/video4linux/cx2341x/fw-encoder-api.txt new file mode 100644 index 000000000000..64cd111349ad --- /dev/null +++ b/Documentation/video4linux/cx2341x/fw-encoder-api.txt @@ -0,0 +1,672 @@ +Encoder firmware API description +================================ + +------------------------------------------------------------------------------- + +Name CX2341X_ENC_PING_FW +Enum 128/0x80 +Description + Does nothing.

I then checked for more and added them in where necessary. They may not actually be necessary in all these locations, but if not, they'll simply have no effect. Add small delay to stv0299 pll gate control to fix tuning problems.

That's why every demod-driver is having a field of dvb_frontend_ops in its private-state-struct and using the reference for filling the pointer-field in dvb_frontend. - It saves at least two lines of code per demod-driver, - reduces object size (one less dereference per frontend_ops-access), - be coherent with dvb_tuner_ops, - makes it a little bit easier for newbies to understand how it works and - avoids stupid mistakes because you would have to copy the dvb_frontend_ops always, before you could assign the static pointer directly, which was dangerous.

Within the kernel, that's not a problem because already includes . However, there are user apps that try to include videodev2.h (e.g., ekiga) and at least on ia64, it causes compilation failures since doesn't get included for any other reason, leaving __u8 etc. undefined.

It shouldn't have there any kernel-specific stuff. Those were moved to v4l2-dev.h. This patch removes some uneeded headers and include v4l2-common.h on all V4L driver. This header includes device implementation of V4L2 API provided on v4l2-dev.h as well as V4L2 internal ioctls that provides connections between master driver and its i2c devices.

The zoran driver uses strncpy() in an unsafe way. This patch uses the proper sizeof()-1 size parameter. Since all strncpy() targets are initialised with memset() the trailing '\0' is already set. Where std->name was the target for the strncpy() we overwrote 8 Bytes of the std structure with zeros.

What happens is that we lock cam->busy_lock, then proceed to free resources, and in the case of (--cam->open_count == 0) we finish off by doing a kfree(cam) and then at the end of the function we do a mutex_unlock(&cam->busy_lock) which will explode since it'll dereference the free'd `cam' : ... mutex_lock(&cam->busy_lock); ... if (--cam->open_count == 0) { ... if (!cam->present) { video_unregister_device(dev); kfree(cam); } } mutex_unlock(&cam->busy_lock); <--- PROBLEM, cam no longer around. ... Since this only happens in the case of open_count going down to zero I don't see a problem with just releasing the mutex after unregistering the device and just before the kfree(). In this case there is nothing around that we can race against; we are in the release method, open_count is zero, (!cam->present) and the device has just been unregistered, so letting go of the mutex at this point looks safe to me.

Control processing is often duplicated in the various drivers. Unfortunately, simple things like the names of controls are often different between drivers, even though it is the same controls. Adding in the new extended controls and the need for having control helper functions became apparent. Several functions have now been added to v4l2-common to do things like filling the v4l2_queryctrl and v4l2_querymenu structs, to check for valid control input and to move to the next control when enumerating over all controls.

Most uses a tda988[5/6/7] IF demodulator as part of the device. Having this as a separate stuff makes harder to configure it, since there are some tda9887 options that are tuner-dependent and should be bound into tuner-types structures. This patch merges tda9887 module into tuner. More work is required to make tuner-types to properly use it.

Failing to do so hid them from the VM. A_T_P just means that the aop method unlocked the page rather than performing IO. It would be very rare that the page was truncated between the unlock and testing A_T_P. So we leave the pages in the LRU for likely reuse soon rather than backing them back out of the page cache. We do this by matching the behaviour before the A_T_P introduction which added pages to the LRU regardless of what ->readpage() did. This doesn't include the unrelated cleanup in Nick's initial fix which changed read_pages() to return void to match its only caller's behaviour of ignoring errors.

There is no need to set VM_SHM since it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not place pages on the LRU. The pages are therefore never subject to swap anyways.

That function may perform page migration on its own (some vmas may not contain page structs and therefore cannot be handled by regular page migration. Pages in a vma may require special preparatory treatment before migration is possible etc) . Only mmap_sem is held when the migration function is called. The migrate() function gets passed two sets of nodemasks describing the source and the target of the migration. The flags parameter either contains MPOL_MF_MOVE which means that only pages used exclusively by the specified mm should be moved or MPOL_MF_MOVE_ALL which means that pages shared with other processes should also be moved. The migration function returns 0 on success or an error condition. An error condition will prevent regular page migration from occurring. On its own this patch cannot be included since there are no users for this functionality. But it seems that the uncached allocator will need this functionality at some point.

This change moves all the code from the asm-i386/mach-*/setup_arch_pre/post.h headers, into arch/i386/mach-*/setup.c. mach-*/setup_arch_pre.h is renamed to setup_arch.h, and contains only things which should be in header files. It is purely code-motion; there should be no functional changes at all. Several functions in arch/i386/kernel/setup.c needed to be made non-static so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is used to hold the prototypes for these functions.

For those architectures with optimized per-cpu implementations, namely ia64, powerpc, s390, sparc64 and x86_64, per_cpu() turns into more and slower code than __get_cpu_var(), so it would be preferable to use __get_cpu_var on those platforms. This defines a __raw_get_cpu_var(x) macro which turns into per_cpu(x, raw_smp_processor_id()) on architectures that use the generic per-cpu implementation, and turns into __get_cpu_var(x) on the architectures that have an optimized per-cpu implementation.

The situation the same: in ufs_trunc_(not direct), we read block, check if count of links to it is equal to one, if so we finish cycle, if not continue.

When file is growing its tail occupy 1 fragment, 2 fragments... At some stage decision to allocate whole block is made and all fragments are moved to one block. How this situation was handled before: ufs_prepare_write ->block_prepare_write ->ufs_getfrag_block ->... ->ufs_new_fragments: bh = sb_bread bh->b_blocknr = result + i; mark_buffer_dirty (bh); This is wrong solution, because: - it didn't take into consideration that there is another cache: "inode page cache" - because of sb_getblk uses not b_blocknr, (it uses page->index) to find certain block, this breaks sb_getblk. How this situation is handled now: we go though all "page inode cache", if there are no such page in cache we load it into cache, and change b_blocknr.

The main bugs: * for i in `seq 1 1000`; do touch $i; done - crash system * mkdir create directory without "." and ".." entries The suggested solution is work with page cache instead of straight work with blocks. Such solution has following advantages * reduce code size and its complexity * some global locks go away * fix bugs The most part of code is stolen from ext2, because of it has similar directory structure. Patches testes with UFS1 and UFS2 file systems. This patch installs i_mapping->a_ops for directory inodes and removes some duplicated code.

} and USPI_UBH has some sence, ucpi looks like struct { struct not_ufs_buffer_head; } To prevent bugs in future, this patch convert macros to inline function and fix "ucpi" structure.

Currently, there are two methods to work with ufs super block: 1) split structure which describes ufs super blocks into structures with size <=512 2) use one structure which describes ufs super block, and hope that array of "buffer_head" which holds "super block", has such construction: bh[n]->b_data + bh[n]->b_size == bh[n + 1]->b_data The second variant may cause some problems in the future, and usage of two variants cause unnecessary code duplication. This patch remove the second variant. Also patch contains some CodingStyle fixes.

UFS1 hold this information in one location and uses 32bit integers for such information, UFS2 hold statistic in another location and uses 64bit integers. There is transition variant, if UFS1 has type 44BSD and flags field in super block has some special value this mean that we work with statistic like UFS2 does. and this also means that nobody care about old(UFS1) statistic. So if start fsck against such file system, after usage linux ufs driver, it found error: at now only UFS1 like statistic is updated. This patch should fix this. Also it contains some minor cleanup: CodingSytle and remove unused variables.

The stated explanation is that console drivers may require per-cpu resources, or otherwise barf, because the system is not yet setup correctly. Fair enough. However some console drivers might be quite happy running early during boot, in fact we have one, and so it'd be nice if printk understood that. So I added a flag (which I would have called CON_BOOT, but that's taken) called CON_ANYTIME, which indicates that a console is happy to be called anytime, even if the cpu is not yet online. Tested on a Power 5 machine, with both a CON_ANYTIME driver and a bogus console driver that BUG()s if called while offline. No problems AFAICT. Built for i386 UP & SMP.

This is a forward port to 2.6.16 (from RHEL) of the minimal changes for the end of media problem. It may not be sufficient for some controllers (promise notably) and it does not touch the locking so the error path locking is as horked as in mainstream. From: Ingo Molnar I have ported the patch to 2.6.17-rc4 and tested it by provoking end-of-media IO errors with an unaligned ISO image. Unlike the vanilla kernel, the patched kernel interpreted the error condition correctly with 512 byte granularity: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown ATAPI device hdc: Error: Illegal request -- (Sense key=0x05) Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00) The failed "Read 10" packet command was: "28 00 00 04 fb 78 00 00 06 00 00 00 00 00 00 00 " end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 Buffer I/O error on device hdc, logical block 163261 Buffer I/O error on device hdc, logical block 163262 the unpatched kernel produces an incorrect error dump: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306088 Buffer I/O error on device hdc, logical block 163261 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306096 Buffer I/O error on device hdc, logical block 163262 I do not have the right type of CD-ROM drive to reproduce the end-of-media data corruption bug myself, but this same patch in RHEL solved it.

Rework it so that we do one 8192-byte allocation and then a pile of tiny ones, via alloc_percpu(). This has a much higher chance of success (100% in the current VM). This also has the effect of reducing the memory requirements from NR_CPUS*n to num_possible_cpus()*n.

This second kernel is booted with very little memory. The first kernel -reserves the section of memory that the second kernel uses. This ensures that -on-going DMA from the first kernel does not corrupt the second kernel. +Overview +======== -All the necessary information about Core image is encoded in ELF format and -stored in reserved area of memory before crash. Physical address of start of -ELF header is passed to new kernel through command line parameter elfcorehdr=. +Kdump uses kexec to quickly boot to a dump-capture kernel whenever a +dump of the system kernel's memory needs to be taken (for example, when +the system panics). The system kernel's memory image is preserved across +the reboot and is accessible to the dump-capture kernel. -On i386, the first 640 KB of physical memory is needed to boot, irrespective -of where the kernel loads. Hence, this region is backed up by kexec just before -rebooting into the new kernel. +You can use common Linux commands, such as cp and scp, to copy the +memory image to a dump file on the local disk, or across the network to +a remote system. -In the second kernel, "old memory" can be accessed in two ways. +Kdump and kexec are currently supported on the x86, x86_64, and ppc64 +architectures. -- The first one is through a /dev/oldmem device interface. A capture utility - can read the device file and write out the memory in raw format. This is raw - dump of memory and analysis/capture tool should be intelligent enough to - determine where to look for the right information. ELF headers (elfcorehdr=) - can become handy here. +When the system kernel boots, it reserves a small section of memory for +the dump-capture kernel. This ensures that ongoing Direct Memory Access +(DMA) from the system kernel does not corrupt the dump-capture kernel. +The kexec -p command loads the dump-capture kernel into this reserved +memory. -- The second interface is through /proc/vmcore. This exports the dump as an ELF - format file which can be written out using any file copy command - (cp, scp, etc). Further, gdb can be used to perform limited debugging on - the dump file. This method ensures methods ensure that there is correct - ordering of the dump pages (corresponding to the first 640 KB that has been - relocated). +On x86 machines, the first 640 KB of physical memory is needed to boot, +regardless of where the kernel loads. Therefore, kexec backs up this +region just before rebooting into the dump-capture kernel. -SETUP -===== +All of the necessary information about the system kernel's core image is +encoded in the ELF format, and stored in a reserved area of memory +before a crash.

This is a problem because a concurrent read (which admittedly is an odd thing to do) might see zeros rather that was there before the write, or what was there after, or some mixture of the two (any of these being a reasonable thing to see). If the copy did fail, it will immediately be retried with preemption re-enabled so any transient problem with accessing the source won't cause an error. The first copying does not need to zero any uncopied bytes, and doing so causes the problem. It uses copy_from_user_atomic rather than copy_from_user so the simple expedient is to change copy_from_user_atomic to *not* zero out bytes on failure. The first of these two patches prepares for the change by fixing two places which assume copy_from_user_atomic does zero the tail. The two usages are very similar pieces of code which copy from a userspace iovec into one or more page-cache pages. These are changed to remove the assumption. The second patch changes __copy_from_user_inatomic* to not zero the tail. Once these are accepted, I will look at similar patches of other architectures where this is important (ppc, mips and sparc being the ones I can find). This patch: There is a problem with __copy_from_user_inatomic zeroing the tail of the buffer in the case of an error. As it is called in atomic context, the error may be transient, so it results in zeros being written where maybe they shouldn't be. In the usage in filemap, this opens a window for a well timed read to see data (zeros) which is not consistent with any ordering of reads and writes. Most cases where __copy_from_user_inatomic is called, a failure results in __copy_from_user being called immediately. As long as the latter zeros the tail, the former doesn't need to. However in *copy_from_user_iovec implementations (in both filemap and ntfs/file), it is assumed that copy_from_user_inatomic will zero the tail. This patch removes that assumption, so that after this patch it will be safe for copy_from_user_inatomic to not zero the tail. This patch also adds some commentary to filemap.h and asm-i386/uaccess.h. After this patch, all architectures that might disable preempt when kmap_atomic is called need to have their __copy_from_user_inatomic* "fixed".

This patch implements that change for i386. For the _nocache version, a new __copy_user_intel_nocache is defined similar to copy_user_zeroio_intel_nocache, and this is ultimately used for the copy. For the regular version, __copy_from_user_ll_nozero is defined which uses __copy_user and __copy_user_intel - the later needs casts to reposition the __user annotations. If copy_from_user_atomic is given a constant length of 1, 2, or 4, then we do still zero the destintion on failure. This didn't seem worth the effort of fixing as the places where it is used really don't care.

While trying to fix them, it seems quite confusing in the ext3 code where some blocks are filesystem-wide blocks, some are group relative offsets that need to be signed value (as -1 has special meaning). So it seem saner to define two types of physical blocks: one is filesystem wide blocks, another is group-relative blocks. The following patches clarify these two types of blocks in the ext3 code, and fix the type bugs which limit current 32 bit ext3 filesystem limit to 8TB. With this series of patches and the percpu counter data type changes in the mm tree, we are able to extend exts filesystem limit to 16TB. This work is also a pre-request for the recent >32 bit ext3 work, and makes the kernel to able to address 48 bit ext3 block a lot easier: Simply redefine ext3_fsblk_t from unsigned long to sector_t and redefine the format string for ext3 filesystem block corresponding. Two RFC with a series patches have been posted to ext2-devel list and have been reviewed and discussed: http://marc.theaimsgroup.com/?l=ext2-devel&m=114722190816690&w=2 http://marc.theaimsgroup.com/?l=ext2-devel&m=114784919525942&w=2 Patches are tested on both 32 bit machine and 64 bit machine, <8TB ext3 and >8TB ext3 filesystem(with the latest to be released e2fsprogs-1.39). Tests includes overnight fsx, tiobench, dbench and fsstress. This patch: Defines ext3_fsblk_t and ext3_grpblk_t, and the printk format string for filesystem wide blocks. This patch classifies all block group relative blocks, and ext3_fsblk_t blocks occurs in the same function where used to be confusing before. Also include kernel bug fixes for filesystem wide in-kernel block variables. There are some fileystem wide blocks are treated as int/unsigned int type in the kernel currently, especially in ext3 block allocation and reservation code. This patch fixed those bugs by converting those variables to ext3_fsblk_t(unsigned long) type.

Like I explained in another email, and directly to Arjan, this can't happen in reality because of the explicit check at eventpoll.c:592, that does not allow to drop an epoll fd inside the same epoll fd. Since lockdep is working on per-structure locks, it will never be able to know of policies enforced in other parts of the code. It was decided time ago of having the ability to drop epoll fds inside other epoll fds, that triggers a very trick wakeup operations (due to possibly reentrant callback-driven wakeups) handled by the ep_poll_safewake() function. While looking again at the code though, I noticed that all the operations done on the epoll's main structure wait queue head (->wq) are already protected by the epoll lock (->lock), so that locked-style functions can be used to manipulate the ->wq member. This makes both a lock-acquire save, and lockdep happy.

I normally do not run with timestamps (since syslog handles that in a good manner), but for measuring small kernel delays (e.g. irq probing - see parport thread) I needed subsecond precision, but then again, just for some minutes rather than all kernel messages to come. The following patch adds a module_param() with which the timestamps can be en-/disabled in a live system through /sys/modules/printk/parameters/printk_time.

There's a whole cluster of RTCs that are very similar, but the 1337 driver was a bit too picky to work with most of them. Still no support for RTC alarm IRQs (on chips that support them).

This makes UIE-less rtc drivers work better with programs doing read/poll on /dev/rtc, such as hwclock. This emulation should not harm rtc drivers with UIE support, since rtc_dev_ioctl() calls underlaying rtc driver's ioctl() first.

Among the NPTL test failures seen are some arising from sigsuspend problems for N32: it blocks the wrong signals, so SIGCANCEL (SIGRTMIN) is blocked despite glibc's carefully excluding it from sets of signals to block. Specifically, testing suggests it blocks signal N^32 instead of signal N, so (in the example tested) blocking SIGUSR1 (17) blocks signal 49 instead. glibc's sigset_t uses an array of unsigned long, as does the kernel. In both cases, signal N+1 is represented as (1UL << (N % (8 * sizeof (unsigned long)))) in word number (N / (8 * sizeof (unsigned long))). Thus the N32 glibc uses an array of 32-bit words and the N64 kernel uses an array of 64-bit words. For little-endian, the layout is the same, with signals 1-32 in the first 4 bytes, signals 33-64 in the second, etc.; for big-endian, userspace has that layout while in the kernel each 8 bytes have the two halves swapped from the userspace layout. The N32 sigsuspend syscall uses sigset_from_compat to convert the userspace sigset to kernel format. If __COMPAT_ENDIAN_SWAP__ is *not* set, this uses logic of the form set->sig[0] = compat->sig[0] | (((long)compat->sig[1]) << 32 ) to convert the userspace sigset to a kernel one. This looks correct to me for both big and little endian, given that in userspace compat->sig[1] will represent signals 33-64, and so will the high 32 bits of set->sig[0] in the kernel. If however __COMPAT_ENDIAN_SWAP__ *is* set, as it is for __MIPSEL__, it uses set->sig[0] = compat->sig[1] | (((long)compat->sig[0]) << 32 ); which seems incorrect for both big and little endian, and would explain the observed symptoms. This code is the only use of __COMPAT_ENDIAN_SWAP__, so if incorrect then that macro serves no purpose, in which case something like the following patch would seem appropriate to remove it.

Quoth SUSv3: open(2): If O_TRUNC is set and the file did previously exist, upon successful completion, open() shall mark for update the st_ctime and st_mtime fields of the file. truncate(2): Upon successful completion, if the file size is changed, this function shall mark for update the st_ctime and st_mtime fields of the file, and the S_ISUID and S_ISGID bits of the file mode may be cleared. ftruncate(2): Upon successful completion, if fildes refers to a regular file, the ftruncate() function shall mark for update the st_ctime and st_mtime fields of the file and the S_ISUID and S_ISGID bits of the file mode may be cleared. If the ftruncate() function is unsuccessful, the file is unaffected. The open(O_TRUNC) and truncate cases were being handled correctly, but the ftruncate case was being handled like the truncate case. The semantics of truncate and ftruncate don't quite match, so ftruncate needs to be handled slightly differently. The attached patch addresses this issue for ftruncate(2).

Michael Tokarev described the problem as: [QUOTE] Suppose there's a CD-rom with a scratch/etc, one sector is unreadable. In order to "fix" it, one have to read it and write to another CD-rom, or something.. or just ignore the error (if it's just a skip in a video stream). Let's assume the unreadable block is number U. But current behavior is just insane. An application requests block number N, which is before U. Kernel tries to read-ahead blocks N..U. Cdrom drive tries to read it, re-read it.. for some time. Finally, when all the N..U-1 blocks are read, kernel returns block number N (as requested) to an application, successefully. Now an app requests block number N+1, and kernel tries to read blocks N+1..U+1. Retrying again as in previous step. And so on, up to when an app requests block number U-1. And when, finally, it requests block U, it receives read error. So, kernel currentry tries to re-read the same failing block as many times as the current readahead value (256 (times?) by default). This whole process already killed my cdrom drive (I posted about it to LKML several months ago) - literally, the drive has fried, and does not work anymore. Ofcourse that problem was a bug in firmware (or whatever) of the drive *too*, but.. main problem with that is current readahead logic as described above. [/QUOTE] Which was confirmed by Jens Axboe : [QUOTE] For ide-cd, it tends do only end the first part of the request on a medium error. So you may see a lot of repeats :/ [/QUOTE] With this patch, retries are expected to be reduced from, say, 256, to 5.

An empty directory '/sys/fs/fuse/connections' is still created in sysfs, and mounting the control filesystem here provides backward compatibility. Advantages of the control filesystem over the previous solution: - allows the object directory and the attributes to be owned by the filesystem owner, hence letting unpriviled users abort the filesystem connection - does not suffer from module unload race [akpm@osdl.org: fix this fs for recent dhowells depredations] [akpm@osdl.org: fix 64-bit printk warnings] Signed-off-by: Miklos Szeredi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- Documentation/filesystems/fuse.txt | 30 +++-- fs/fuse/Makefile | 2 +- fs/fuse/control.c | 218 +++++++++++++++++++++++++++++++++++++ fs/fuse/dev.c | 2 +- fs/fuse/fuse_i.h | 53 +++++++-- fs/fuse/inode.c | 141 ++++++++---------------- 6 files changed, 331 insertions(+), 115 deletions(-) create mode 100644 fs/fuse/control.c diff --git a/Documentation/filesystems/fuse.txt b/Documentation/filesystems/fuse.txt index e7747774ceb9..324df27704cc 100644 --- a/Documentation/filesystems/fuse.txt +++ b/Documentation/filesystems/fuse.txt @@ -18,6 +18,14 @@ Non-privileged mount (or user mount): user.

This implementation doesn't keep any locking state in kernel. Unlocking on close() is handled by the FLUSH message, which now contains the lock owner id. Mandatory locking is not supported. The filesystem may enfoce mandatory locking in userspace if needed.

So scramble it with XTEA using a per connection random key, known only to the kernel. Only one direction needs to be implemented, since the ID is never sent in the reverse direction. The XTEA algorithm is implemented inline since it's simple enough to do so, and this adds less complexity than if the crypto API were used. Thanks to Jesper Juhl for the idea.

When the verbose (-v) option is used with scripts/kernel-doc, this option reports when the kernel-doc format is malformed and apparently contains function description lines before function parameters. In these cases, the kernel-doc script will print something like: Warning(filemap.c:335): contents before sections I have fixed the problems in mm/filemap.c and added lots of kernel-doc to that file (posted to the linux-mm mailing list Mon. 2006-June-12). The real goal (as requested by Andrew Morton) is to allow the short function description to be more than one line long. This patch is both a kernel-doc checker and a tool en route to that goal.

The following patch should change that. My tests show that this is all that's needed. If OLDNAME is a symlink setting the flag causes linkat to follow the symlink and create a hardlink with the target. This is actually the behavior POSIX demands for link() as well but Linux wisely does not do this. With this flag (which will most likely be in the next POSIX revision) the programmer can choose the behavior, defaulting to the safe variant. As a side effect it is now possible to implement a POSIX-compliant link(2) function for those who are interested. touch file ln -s file symlink linkat(fd, "symlink", fd, "newlink", 0) -> newlink is hardlink of symlink linkat(fd, "symlink", fd, "newlink", AT_SYMLINK_FOLLOW) -> newlink is hardlink of file The value of AT_SYMLINK_FOLLOW is determined by the definition we already use in glibc.

Previously the code effectively treated a size of 0 as a size of 4G (on 32-bit systems), with other checks preventing it from actually trying to emit the string - but the terminal \0 would still be written, which would crash if the buffer is NULL. This change changes the boundary check so that 'end' points to the putative location of the terminal '\0', which is only written if size > 0. vsnprintf still allows the buffer size to be set very large, to allow unbounded buffer sizes (to implement sprintf, etc).

Some applications (radio/satellite modems, connections to legacy military hardware) require non-standard patterns.

There is a possibility this exitcode is not the group leader's one. --- include/linux/acct.h | 8 ++++---- include/linux/sched.h | 2 ++ kernel/acct.c | 42 ++++++++++++++++++++++++------------------ kernel/exit.c | 4 ++-- 4 files changed, 32 insertions(+), 24 deletions(-) diff --git a/include/linux/acct.h b/include/linux/acct.h index 5bca9b3ef2d7..e86bae7324d2 100644 --- a/include/linux/acct.h +++ b/include/linux/acct.h @@ -122,16 +122,16 @@ struct super_block; extern void acct_auto_close_mnt(struct vfsmount *m); extern void acct_auto_close(struct super_block *sb); extern void acct_init_pacct(struct pacct_struct *pacct); -extern void acct_collect(); -extern void acct_process(long exitcode); +extern void acct_collect(long exitcode, int group_dead); +extern void acct_process(void); extern void acct_update_integrals(struct task_struct *tsk); extern void acct_clear_integrals(struct task_struct *tsk); #else #define acct_auto_close_mnt(x) do { } while (0) #define acct_auto_close(x) do { } while (0) #define acct_init_pacct(x) do { } while (0) -#define acct_collect() do { } while (0) -#define acct_process(x) do { } while (0) +#define acct_collect(x,y) do { } while (0) +#define acct_process() do { } while (0) #define acct_update_integrals(x) do { } while (0) #define acct_clear_integrals(task) do { } while (0) #endif diff --git a/include/linux/sched.h b/include/linux/sched.h index abada7c1d5e4..d8429dc250f0 100644 --- a/include/linux/sched.h +++ b/include/linux/sched.h @@ -359,6 +359,8 @@ struct sighand_struct { }; struct pacct_struct { + int ac_flag; + long ac_exitcode; unsigned long ac_mem; }; diff --git a/kernel/acct.c b/kernel/acct.c index b35263137824..4c85fdf615da 100644 --- a/kernel/acct.c +++ b/kernel/acct.c @@ -75,7 +75,7 @@ int acct_parm[3] = {4, 2, 30}; /* * External references and all of the globals. */ -static void do_acct_process(long, struct file *); +static void do_acct_process(struct file *); /* * This structure is used so that all the data protected by lock @@ -196,7 +196,7 @@ static void acct_file_reopen(struct file *file) if (old_acct) { mnt_unpin(old_acct->f_vfsmnt); spin_unlock(&acct_globals.lock); - do_acct_process(0, old_acct); + do_acct_process(old_acct); filp_close(old_acct, NULL); spin_lock(&acct_globals.lock); } @@ -419,7 +419,7 @@ static u32 encode_float(u64 value) /* * do_acct_process does all actual work.

The pacct facility also uses it as a per-process data structure to store stime, utime, minflt, majflt. But those members are saved in __exit_signal(). It's too late. For example, if some threads exits at same time, pacct facility has a possibility to drop accountings for a part of those threads. (see, the following 'The results of original 2.6.17 kernel') I think accounting information should be completely collected into the per-process data structure before writing out an accounting record. This patch fixes this matter. Accumulation of stime, utime, minflt and majflt are done before generating accounting record.

The code in arch/x86_64/kernel/setup.c to reserve boot memory for the crash kernel uses the non-numa aware "reserve_bootmem" function instead of the NUMA aware "reserve_bootmem_generic". I checked to make sure that no other function was using "reserve_bootmem" and found none, except the ones that had NUMA ifdef'ed out.
