-- cgit v1.2.3 From da3bc07171dff957906cbe2ad5abb443eccf57c4 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 18 Jan 2009 21:50:16 -0800 Subject: sfc: Replace LRO with GRO This patch makes sfc invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. Everything should appear identical to the user except that the offload is now controlled by the GRO ethtool option instead of LRO. I've kept the lro module parameter as is since that's for compatibility only. I have eliminated efx_rx_mk_skb as the GRO layer can take care of all packets regardless of whether GRO is enabled or not. So the only case where we don't call GRO is if the packet checksum is absent. This is to keep the behaviour changes of the patch to a minimum. Signed-off-by: Herbert Xu Signed-off-by: David S.

As GRO has a compatible external interface to LRO this is a very straightforward replacement. Three things of note: 1) I've kept the LRO Kconfig option until we decide to enable GRO across the board at which point it can also be killed. 2) The poll_controller stuff is broken in igb as it tries to do the same work as the normal poll routine. Since poll_controller can be called in the middle of a poll, this can't be good. I noticed this because poll_controller can invoke the GRO hooks without flushing held GRO packets. However, this should be harmless (assuming the poll_controller bug above doesn't kill you first :) since the next ->poll will clear the backlog. The only time when we'll have a problem is if we're already executing the GRO code on the same ring, but that's no worse than what happens now. 3) I kept the ip_summed check before calling GRO so that we're on par with previous behaviour.

As GRO has a compatible external interface to LRO this is a very straightforward replacement. I've kept the ioctl controls for per-queue LRO switches. However, we should not encourage anyone to use these. Because of that, I've also kept the skb construction code in cxgb3. Hopefully we can phase out those per-queue switches and then kill this too.

-- cgit v1.2.3 From a6bcf1c1d38e0672db35e0d9f2504ac04ddf3ed5 Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Wed, 21 Jan 2009 15:54:54 -0800 Subject: net: pppoe - introduce net-namespace functionality - each net-namespace for pppoe module is having own hash table and appropriate locks wich are allocated at time of namespace intialization. It requires about 140 bytes of memory for every new namespace but such approach allow us to escape from hash chains growing and additional lock contends (especially in SMP environment). - pppox code allows to create per-namespace sockets for PX_PROTO_OE protocol only (since at this moment support for pppol2tp net-namespace is not implemented yet).

Biederman" Date: Tue, 20 Jan 2009 11:07:17 +0000 Subject: tun: Fix races between tun_net_close and free_netdev. The tun code does not cope gracefully if the network device goes away before the tun file descriptor is closed. It looks like we can trigger this with rmmod, and moving tun devices between network namespaces will allow this to be triggered when network namespaces exit. To fix this I introduce an intermediate data structure tun_file which holds a count of users and a pointer to the struct tun_struct. tun_get increments that reference count if it is greater than 0. tun_put decrements that reference count and detaches from the network device if the count is 0. While we have a file attached to the network device I hold a reference to the network device keeping it from going away completely. When a network device is unregistered I decrement the count of the attached tun_file and if that was the last user I detach the tun_file, and all processes on read_wait are woken up to ensure they do not sleep indefinitely. As some of those sleeps happen with the count on the tun device elevated waking up the read waiters ensures that tun_file will be detached in a timely manner. Signed-off-by: Eric W.

Further it allows removal network namespace operations for the tun driver. Reducing the network namespace handling in the driver to the minimum. i.e. When we are creating a tun device.

It was observed by Don Ash that e1000e was acquiring this lock in the NAPI cleanup path. This is obviously a bug, as this is a leftover from when e1000 supported multiple tx queues and fake netdevs. another user reported this to us and tested routing with the 2.6.27 kernel and this patch and reported a 3.5 % improvement in packets forwarded in a multi-port test on 82571 parts.

However, this means that we _do_ make init_module() wait for it, and it takes a long time for now (since we're using ultra-conservative code in the FPGA for that too). The inner loop which uses swahb32p() was by Simon Farnsworth. Simon has patches which migrate us to request_firmware_nowait(), for which we'll actually need to take down the ATM devices, do the upgrade, then reregister them.

Both 16-bit and 32-bit CMT versions are supported, but only 32-bit is tested. This driver contains support for both clockevents and clocksources, but no unregistration is supported at this point. Works fine as clock source and/or event in periodic or oneshot mode. Tested on sh7722 and sh7723, but should work with any cpu/architecture. This version is lacking clocksource and early platform driver support for now - this to minimize the amount of dependencies.

Because this is an indirect register access has some costs attached to it (especially for USB hardware). We already store the value read from the register into the vgc_level value inside the link structure. Instead of reading from the register we can read that field directly and base the tuner on that value. This reduces the time the registers are locked with the csr_mutex and speeds up the link_tuner processing. Signed-off-by: Ivo van Doorn Signed-off-by: John W.

The contents of these fields are for the drivers and all fields are allowed to be changed to values the driver considers correct. This means that some fields need to be moved outside of this structure to restrict access only to rt2x00link itself. This allows some code to be moved outside of the rt2x00.h header and into rt2x00link.c. Signed-off-by: Ivo van Doorn Signed-off-by: John W.

The initial goal was to replace the channel info structure. Once we do that, and then include iwl-dev.h instead of iwl-3945.h, we still get build errors due to several routines and macro redefinitions. This is why this patch also includes: - TFD39_MAX_PAYLOAD definition for 3945. - CMD_SIZE, CMD_HUGE, CMD_SKB duplication removal. - iwl3945_queue replacement in order to also get rid of the duplicated get_cmd_index routine. Getting rid of any of those needs the iwl-dev.h inclusion which then creates build errors due to definitions duplication. This is why we include all those in the same patch.

Hence this patch changes the probing for 11g capabilities to discard 11g capabilities for ar5211 cards which allows this specific card to work fine in 11b and 11a modes.

This has implications on user space tools (like NetworkManager) relying on rfkill notifications to bring the interface up once the wireless gets enabled through a hw killswitch. Thus, enable the device already in iwl3945_pci_probe instead of iwl3945_up and poll the CSR_GP_CNTRL register to update the killswitch state every two seconds. The polling is only needed on 3945 hardware as this adapter does not use interrupts to signal rfkill changes to the driver (in case no firmware is loaded). The firmware loading is still done in iwl3945_up. Signed-off-by: Helmut Schaa Acked-by: Samuel Ortiz Signed-off-by: John W.

This has implications on user space tools (like NetworkManager) relying on rfkill notifications to bring the interface up once the wireless gets enabled through a hw killswitch. Thus, enable the device already in iwl_pci_probe instead of iwl_up and enable interrups while the interface is down in order to get notified about killswitch state changes.

Since the 3945 host command specific routines are identical to the agn ones, we can just remove them from the 3945 code.

A warning message "MAC is in deep sleep" sometimes happen when user removes the driver. This warning is related to card not being ready.

We only keep data we need to provide our own regulatory_hint(), reg_notifier() and information necessary for calibration. Atheros hardware supports 12 world regulatory domains, since these are custom we apply them through the the new wiphy_apply_custom_regulatory(). Although we have 12 we can consolidate these into 5 structures based on frequency and apply a different set of flags that differentiate them on a case by case basis through the reg_notifier(). If CRDA is not found our own custom world regulatory domain is applied, this is identical to cfg80211's except we enable passive scan on most frequencies. Signed-off-by: Luis R.

8cab7581dba90b0519e25784e08feb5dedde737f Mon Sep 17 00:00:00 2001 From: Alina Friedrichsen Date: Fri, 23 Jan 2009 05:39:13 +0100 Subject: ath5k: Read and write the TSF via debugfs This patch updates

This way around it's a win-win situation. 1) If proprietary fw is available, it will work. 2) If opensource firmware is available, but no proprietary (Distros can only ship open fw) it might work. 3) If both open and proprietary are available, it will work, because it selects the proprietary. We currently don't prefer the open fw in this case, because it doesn't work on all devices. It would introduce a regression otherwise. The remaining FIXMEs in this patch are harmless, because they only matter on multiband devices, which are not implemented yet anyway. Signed-off-by: Michael Buesch Signed-off-by: John W.

This enables us to dynamically enable debugging messages (or disable info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose. This increases the module size by about 3k. But in practice it reduces the module size for the user, because some distributions ship the b43 module with CONFIG_B43_DEBUG set, which increases the module by about 15k. So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG. There is no reason to keep it in a production-release kernel. So we have a net reduction in size by about 12k. This patch also adds a printk of the wireless core revision, so people don't have to enable SSB debugging to get the wireless core revision. Signed-off-by: Michael Buesch Signed-off-by: John W.

But for SOC ethernets we have separate devices. So, in SOC case, checking whether MDIO controller may wakeup is not only makes little sense, but also prevents us from doing per-netdevice wakeup management. This patch reworks suspend/resume code so that now it checks for net device's wakeup flags, not MDIO controller's ones. Each netdevice should manage its wakeup flags, and phylib will decide whether suspend an attached PHY or not. Signed-off-by: Anton Vorontsov Signed-off-by: David S.

If you launch the test from Documentation/connector and change it a bit to send a high flow of data, you will see thousands of events coming to the "cqueue" workqueue by looking at the workqueue tracer. This flow of events can be sent very quickly. So, to not encumber the kevent workqueue and delay other jobs, the "cqueue" workqueue should remain. But this workqueue is pointless most of the time, it will always be created (assuming you have built it of course) although only developpers with specific needs will use it. So avoid this "most of the time useless task", this patch proposes to create this workqueue only when needed once. The first jobs to be sent to connector callbacks will be sent to kevent while the "cqueue" thread creation will be scheduled to kevent too. The following jobs will continue to be scheduled to keventd until the cqueue workqueue is created, and then the rest of the jobs will continue to perform as usual, through this dedicated workqueue. Each time I tested this patch, only the first event was sent to keventd, the rest has been sent to cqueue which have been created quickly. Also, this patch fixes some trailing whitespaces on the connector files. Signed-off-by: Frederic Weisbecker Acked-by: Evgeniy Polyakov Signed-off-by: David S.

The control transaction consists of one or more "out" sg entries and one or more "in" sg entries. The first out entry contains a header defining the class and command. Additional out entries may provide data for the command. The last in entry provides a status response back from the command. Virtqueues typically run asynchronous, running a callback function when there's data in the channel. We can't readily make use of this in the command paths where we need to use this. Instead, we kick the virtqueue and spin. The kick causes an I/O write, triggering an immediate trap into the hypervisor. Signed-off-by: Alex Williamson Acked-by: Rusty Russell Signed-off-by: David S.

This means that the user-space sender may be able to pin down arbitrary amounts of kernel memory by continuing to send data to an end-point that is congested. Even when this isn't an issue because of limited queueing at most end points, this can also be a problem because its only response to congestion is packet loss. That is, when those local queues at the end-point fills up, the tuntap device will start wasting system time because it will continue to send data there which simply gets dropped straight away. Of course one could argue that everybody should do congestion control end-to-end, unfortunately there are people in this world still hooked on UDP, and they don't appear to be going away anywhere fast. In fact, we've always helped them by performing accounting in our UDP code, the sole purpose of which is to provide congestion feedback other than through packet loss. This patch attempts to apply the same bandaid to the tuntap device. It creates a pseudo-socket object which is used to account our packets just as a normal socket does for UDP. Of course things are a little complex because we're actually reinjecting traffic back into the stack rather than out of the stack. The stack complexities however should have been resolved by preceding patches. So this one can simply start using skb_set_owner_w. For now the accounting is essentially disabled by default for backwards compatibility. In particular, we set the cap to INT_MAX.

With this patch, the caller knows if the delivery of any of the messages to the listeners have failed: 1) If it fails to deliver any message (for whatever reason), return -ENOBUFS. 2) Otherwise, if all messages were delivered OK, returns 0. 3) Otherwise, if no listeners, return -ESRCH. In the current ctnetlink code and in Netfilter in general, we can add reliable logging and connection tracking event delivery by dropping the packets whose events were not successfully delivered over Netlink. Of course, this option would be settable via /proc as this approach reduces performance (in terms of filtered connections per seconds by a stateful firewall) but providing reliable logging and event delivery (for conntrackd) in return. This patch also changes some clients of netlink_broadcast() that may report ENOBUFS errors via printk. This error handling is not of any help. Instead, the userspace daemons that are listening to those netlink messages should resync themselves with the kernel-side if they hit ENOBUFS. BTW, netlink_broadcast() clients include those that call cn_netlink_send(), nlmsg_multicast() and genlmsg_multicast() since they internally call netlink_broadcast() and return its error value.

So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host commands, since the command length as to be set according to the HW. As another precaution the reserved4 and reserved5 fields are cleared before being sent to the 3945. With the *39_rxon removal, a lot of duplicated code can be removed from the 3945 code base.

On some bladeservers this resulted in false link up reports if no link partner was connected. The RXSEQ treatment is not necessary, as the link can be monitored from the watchdog timer, and the false link indications cease.

The lock is used in user, bh and irq + * context, so when taken outside hardirq context it should always be + * taken with interrupts disabled. The lock protects both the + * hardware and the struct orinoco_private. + * + * Another flag, priv->hw_unavailable indicates that the hardware is + * unavailable for an extended period of time (e.g. suspended, or in + * the middle of a hard reset). This flag is protected by the + * spinlock. All code which touches the hardware should check the + * flag after taking the lock, and if it is set, give up on whatever + * they are doing and drop the lock again. The orinoco_lock() + * function handles this (it unlocks and returns -EBUSY if + * hw_unavailable is non-zero). + */ + +#define DRIVER_NAME "orinoco" + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#include +#include + +#include "hermes_rid.h" +#include "hermes_dld.h" +#include "orinoco.h" + +/********************************************************************/ +/* Module information */ +/********************************************************************/ + +MODULE_AUTHOR("Pavel Roskin & " + "David Gibson "); +MODULE_DESCRIPTION("Driver for Lucent Orinoco, Prism II based " + "and similar wireless cards"); +MODULE_LICENSE("Dual MPL/GPL"); + +/* Level of debugging.

This flag is protected by the - * spinlock. All code which touches the hardware should check the - * flag after taking the lock, and if it is set, give up on whatever - * they are doing and drop the lock again. The orinoco_lock() - * function handles this (it unlocks and returns -EBUSY if - * hw_unavailable is non-zero). - */ - -#define DRIVER_NAME "orinoco" - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include - -#include "hermes_rid.h" -#include "hermes_dld.h" -#include "orinoco.h" - -/********************************************************************/ -/* Module information */ -/********************************************************************/ - -MODULE_AUTHOR("Pavel Roskin & " - "David Gibson "); -MODULE_DESCRIPTION("Driver for Lucent Orinoco, Prism II based " - "and similar wireless cards"); -MODULE_LICENSE("Dual MPL/GPL"); - -/* Level of debugging.

Single-thread access must be ensured for ICH8 NVM and PHY operations. This synchronization is provided by the nvm_mutex. To assist in understanding the contexts from which this code could be reached, a WARN was output if the mutex was not going to be immediately acquirable (if !mutex_trylock()). The code has now been optimized, and we have verified that the few remaining mutex contentions are reasonable and non-blocking, and it is time to remove the mutex_trylock() and WARN messages.

Due to hardware limitations it is not possible to verify reliably which packet was time stamped when multiple were pending for sending; this could be solved by only allowing one packet marked for hardware time stamping into the queue (not implemented yet). RX time stamping relies on the flag in the packet descriptor which marks packets that were time stamped. In "all packet" mode this flag is not set.

This patch changes this so that advanced descriptors are used throughout and all mentions of legacy descriptors are removed.

If we free an existing path whose valid flag was zero, (but do not detach it from the list) we cause corruption of the path list (of which it is a member), and get a kernel crash. The simplest solution is to not free an existing path -- just leave it in the list as-is (i.e., with its valid flag cleared). Thanks to Yossi Etigin of Voltaire for identifying the problem flow which caused the kernel crash.

(regular mod_timer() re-activates non-pending timers.) This is useful for the networking code in that it can allow unserialized mod_timer_pending() timer-forwarding calls, but a single del_timer*() will stop the timer from being reactivated again. Also while at it: - optimize the regular mod_timer() path some more, the timer-stat and a debug check was needlessly duplicated in __mod_timer(). - make the exports come straight after the function, as most other exports in timer.c already did. - eliminate __mod_timer() as an external API, change the users to mod_timer(). The regular mod_timer() code path is not impacted significantly, due to inlining optimizations and due to the simplifications.

This read will cause a clear-by-read which leads to two TLP being inserted in the PCIe retry buffer leading to an overflow of the buffer and corruption of TLPs. The solution is different depending where the reading of EICR takes place. For ixgbe_msix_lsc() since we are in MSIX mode and know OCD is enabled a clear-by-write is done instead of the normal clear-by-read. For ixgbe_intr() 0xffffffff is written to EIMC before the read, masking the interrupts. Signed-off-by: Don Skidmore Acked-by: Peter P Waskiewicz Jr Signed-off-by: Jeff Kirsher Signed-off-by: David S.

Further to a71558d, this is round five of fixes to make etherh work again. As mainline kernels stand, the fixes in b9a9b4b were the wrong approach. The 8390 driver was structured by Al Viro to allow the flexibility required by platforms. lib8390.c contains the core code which drivers explicitly include: - 8390.c includes lib8390.c to provide the standard ISA based driver. - etherh.c includes it with the accessors defined for RiscPC platforms, where it is addressed via the MMIO accessors with a device dependent register spacing. Other platform drivers do something similar. However, b9a9b4b caused the kernel to contain not only the etherh private build of lib8390 (included in etherh.c) but also lib8390.c itself, and referred the new net_device_ops methods to the ISA version. The result of this is is not pretty: Unable to handle kernel paging request at virtual address 12032030 pgd = c8330000 [12032030] *pgd=00000000 Internal error: Oops: 18331805 [#1] Modules linked in: ipv6 CPU: 0 Not tainted (2.6.29-rc3 #167) PC is at do_set_multicast_list+0xd0/0x190 LR is at bitrev32+0x28/0x34 pc : [] lr : [] psr: a0000093 sp : c8321d9c ip : c8321d84 fp : c8321dbc r10: c80c6800 r9 : 00000000 r8 : c80c6b60 r7 : c80c6b80 r6 : cc80c800 r5 : c80c6800 r4 : 00000000 r3 : cc80c80c r2 : 00000004 r1 : 00000007 r0 : e0000000 Flags: NzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user ...

(16kB - header size) / 2048 = 7 or 8 pages, which would far exceed 3 adjust the driver to account for these large pages, the hardware can support DMA to up to 16kB for each descriptor.

The old code allows device unregister to proceed even if some sysfs files are open, which leaves a window where userspace can open a file before a device is removed but then end up reading the file after the device is removed, which leads to various kernel crashes either because the device data structure is freed or because the low-level driver code is gone after module removal. By not returning from ib_unregister_device() until after all sysfs entries are removed, we make sure that data structures and/or module code is not freed until after all sysfs access is done.

This patch updates the maple bus to support asynchronous block reads and writes as well as generally improving the quality of the code and supporting concurrency (all needed to support the Dreamcast visual memory unit - a driver will also be posted for that). Changes in the bus driver necessitate some changes in the two maple bus input drivers that are currently in mainline. As well as supporting block reads and writes this code clean up removes some poor handling of locks, uses an atomic status variable to serialise access to devices and more robusly handles the general performance problems of the bus.

While the APD feature only works for 5761 and 5784 asic revisions, the (harmless portion of the) code was applied to all 5705 and newer devices. However, the 5906 phy departs from the usual design. This commit was interfering with the 5906's ability to negotiate link against some switches. This patch corrects the problem.

To preserve the logic at the call sites, this patch also inverts every call to tg3_nvram_read() and tg3_nvram_read_swab(). The call swap gets confusing within tg3_nvram_read_le() (LE is a misnomer), but the reader should be able to convince himself / herself that the resulting behavior is still unchanged.

For the former case, a direct replacement of tg3_nvram_read_swab() with tg3_nvram_read_be32() is in order. For the latter case, we remove tg3_nvram_read_swab() and document what the code is really doing.

This is useful for processors with limited interrupt masking support such as sh7750 and sh7780. With this patch in place we can add logic to the intc code that merges all RTC vectors into a single linux interrupt with proper masking/unmasking support. Specify a single IRQ in the platform data to use this new shared IRQ feature. Separate Periodic/Carry/Alarm IRQs are still supported.

This helps processors such as sh7750, sh7780 and sh7785 which have more vectors than masking ability. With this patch in place we can modify the intc tables to use one irq per maskable irq source. Please note the following: - If multiple vectors share the same enum then only the first vector will be available as a linux irq. - Drivers may need to be rewritten to get pending irq source from the hardware block instead of irq number. This patch together with the sh7785 specific intc tables solves DMA controller irq issues related to buggy interrupt masking.

In this case, local_completions() will be called with local->mad_priv == NULL. The code does check for this case and skips calling recv_mad_agent->agent.recv_handler() but recv == 0 so kmem_cache_free() is called with a NULL pointer.

Rework: - There is not a case when IWLCORE should not be selected. At the same time the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of these two. With IWLWIFI being the driver name we proceed to use just it and replace instances of IWLCORE with it. The module name does not change and is still iwlcore. - Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move this up to one select when IWLWIFI is selected. - IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series. - Now that 3945 depends on IWLWIFI we can also indicate its dependency on MAC80211_LEDS and LEDS_CLASS at this level. - IWLAGN_LEDS is not used by driver - remove it. - IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part of iwlcore module. Move this config up in Kconfig to reflect that and also change name to IWLWIFI_SPECTRUM_MEASUREMENT. - CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to description that indicates this. - CONFIG_IWL3945_RFKILL does not exist - remove usage from driver. - Add "iwlagn" to end of description of IWLAGN to help people understand what iwlagn means in rest of Kconfig text. - Add "iwl3945" to end of description of IWL3945 to help people understand what iwlagn means in rest of Kconfig text. - Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports it (for now).

This is because iwlwifi driver calls DMA mapping with PCI_DMA_TODEVICE which is read only in mapping PTE. But iwlwifi device actually writes to the mapped page to update its contents. This issue is not exposed in swiotlb. But VT-d hardware can capture this fault and stop the fault transaction. The iwl TX command contains a scratch field that is updated by uCode to indicate retry counts. For 5000 series the patch is required also for regular frames, but this patch does not differenciate.

Double the number of TX slots, so we have an effective hardware queue of 128 frames per QoS queue. Also optimize the TX header cache handling. We don't need a cached TX header for slots that will never carry an actual header. So we reduce the memory consumption of the cache by 50%. So as a net result we end up with more or less the same memory usage before and after this patch (except a few tiny meta structures), but have twice the number of TX slots available.

cgit v1.2.3 From 235ea828a1640ed493562a5fe08aa666ff84fbc4 Mon Sep 17 00:00:00 2001 From: PJ Waskiewicz Date: Fri, 27 Feb 2009 15:44:48 +0000 Subject: ixgbe: Add DCB for 82599, remove BCN support This patch adds the DCB (Data Center Bridging) support for 82599 hardware. This is similar to how the 82598 DCB code works. This patch also removes the BCN (Backwards Congestion Notification) netlink configuration code from the driver. BCN was a pre-standard congestion notification framework, and was not what the IEEE body decided upon for standard congestion management. QCN (802.1Qau), Quantized Congestion Notification is the accepted standard, which is not supported by 82599, hence we remove the support altogether.

The firmware loader will try them in sequence until one loads. Thus, if a user doesn't have the latest and greatest firmware that a newly installed kernel would require, the driver would fall back to the firmware from a previous release. To support this, the i2400m->bus_fw_name is changed to be a NULL terminated array firmware file names (and renamed to bus_fw_names) and we add a new entry (i2400m->fw_name) that points to the name of the firmware being currently used. All code that needs to print the firmware file name uses i2400m->fw_name instead of the old i2400m->bus_fw_name. The code in i2400m_dev_bootstrap() that loads the firmware is changed with an iterator over the firmware file name list that tries to load each form user space, using the first one that succeeds in request_firmware() (and thus stopping the iteration). The USB and SDIO bus drivers are updated to take advantage of this and reflect which firmwares they support. Signed-off-by: Inaky Perez-Gonzalez Signed-off-by: David S.

In this mode, the device pages the base-station regularly and when data is ready to be transmitted, the link is revived. This patch allows the user to control the time the device has to be idle before it decides to go to idle mode from a sysfs interace. It also updates the initialization code to acknowledge the module variable 'idle_mode_disabled' when the firmware is a newer version (upcoming 1.4 vs 2.6.29's v1.3). The method for setting the idle mode timeout in the older firmwares is much more limited and can be only done at initialization time. Thus, the sysfs file will return -ENOSYS on older ones.

This header is mainly used to implement host reordeing (which is addressed in later commits). However, this header also allows us to overwrite it (once data has been extracted) with an Ethernet header and deliver to the networking stack without having to reallocate the skb (as it happened in fw <= v1.3) to make room for it. - control.c: indicate the device [dev_initialize()] that the driver wants to use the extended data RX protocol. Also involves adding the definition of the needed data types in include/linux/wimax/i2400m.h. - rx.c: handle the new payload type for the extended RX data protocol. Prepares the skb for delivery to netdev.c:i2400m_net_erx(). - netdev.c: Introduce i2400m_net_erx() that adds the fake ethernet address to a prepared skb and delivers it to the networking stack. - cleanup: in most instances in rx.c, the variable 'single' was renamed to 'single_last' for it better conveys its meaning.

When that is done, the device will indicate the driver if a packet has to be held in a (sorted) queue. It will also tell the driver when held packets have to be released to the OS. This is done to improve the WiMAX-protocol level retransmission support when missing frames are detected. The code docs provide details about the implementation. In general, this just hooks into the RX path in rx.c; if a packet with the reorder bit in the RX header is detected, the reorder information in the header is extracted and one of the four main reorder operations are executed. In one case (queue) no packet will be delivered to the networking stack, just queued, whereas in the others (reset, update_ws and queue_update_ws), queued packet might be delivered depending on the window start for the specific queue. The modifications to files other than rx.c are: - control.c: during device initialization, enable reordering support if the rx_reorder_disabled module parameter is not enabled - driver.c: expose a rx_reorder_disable module parameter and call i2400m_rx_setup/release() to initialize/shutdown RX reorder support. - i2400m.h: introduce members in 'struct i2400m' needed for implementing reorder support. - linux/i2400m.h: introduce TLVs, commands and constant definitions related to RX reorder Last but not least, the rx reorder code includes an small circular log where the last N reorder operations are recorded to be displayed in case of inconsistency. Otherwise diagnosing issues would be almost impossible. Signed-off-by: Inaky Perez-Gonzalez Signed-off-by: David S.

The call was added to improve performance but did so by allowing the skb to be removed from the socket which gave the socket more window space to transmit. The performance gain is not worth the extra problems that this kind of workaround can introduce as this could lead to a potential DoS if a UDP stream decided to monopolize the transmit path.

Due to the complexity of the FW and HW, there are a lot of different regions in the chip - to keep the code as clean as possible, the ranges were put in an H file. Some areas cannot be read if the driver is running - so by default, the driver will not access those areas - but any programmer facing a problem will be able to easily manipulate the driver to extract full dump.

Otherwise, the ib_mad_send_buf will be leaked and the mad_agent reference count will never go to zero and the IB device module cannot be unloaded. The above can happen without this patch if process_mad() returns (IB_MAD_RESULT_SUCCESS | IB_MAD_RESULT_CONSUMED).

Allow multiple VIPs to be registered. Though, number of beaconing VIFs is still limited by ATH_BCBUF (currently 1). Multiple virtual STAs support is not yet complete, but at least the data structures should now be able to handle this. Signed-off-by: Jouni Malinen Signed-off-by: John W.

The goal of virtual radios is to allow the same radio to be shared for multiple virtual interfaces that may operate on different channels. The mac80211 virtual interface support is designed only for single channel operation and as such, it is not suitable for this type of use. Anyway, it can be used on top of the virtual radio concept, if desired (e.g., use two virtual radios to handle two channels and then add multiple mac80211 virtual interfaces on top of each virtual radio). The new struct ath_wiphy is now registered as the driver data structure for wiphy. This structure has a pointer to the shared (among virtual wiphys of the same physical radio) struct ath_softc data. The primary wiphy maintains the allocated memory for ath_softc. Secondary (virtual) wiphys will only allocate the new ath_wiphy structure. Registration of secondary wiphys is added in a separate patch. Signed-off-by: Jouni Malinen Signed-off-by: John W.

This solution prefers to use 4KB PBLs over two level 256B PBLs until the number of 4KB PBLs falls below a threshold. At this point the 4KB PBL structure is converted to use 256B PBLs which prevents the driver from running out of 4KB PBLs too quickly.

To handle MPA Reject call, following changes are done: *Handle inbound/outbound MPA Reject response message. When nes_reject() is called for pending MPA request reply, send the MPA Reject message to its peer (active side)cm_node. The peer cm_node (active side) will indicate Reject message event for the pending Connect Request. *Handle MPA Reject response message for loopback connections and listener. When MPA Request is rejected, check if it is a loopback connection and if it is then it will send Reject message event to its peer loopback node. Also when destroying listener, check if the cm_nodes for that listener are loopback or not. *Add gracefull connection close with the MPA Reject response message. Send gracefull close (FIN, FIN ACK..) to terminate the cm_nodes. *Some code re-org while making the above changes. Removed recv_list and recv_list_lock from the cm_node structure as there can be only one receive close entry on the timer. Also implemented handle_recv_entry() as receive close entry is processed from both nes_rem_ref_cm_node() as well as nes_cm_timer_tick().

This patch adds support for the Sega Dreamcast visual memory unit as a flash mapping. It requires changes in the maple bus driver (posted separately) to support block reads and writes. The VMU is a 'smart' flash device, with a built-in 8-bit controller - for instance there is an erase before a write but it is hidden from the user. But the device's overall behaviour means it works well with the mtd layer and it is appropriate to add it as an mtd mapping.

This will be mode where interrupt moderation logic will dynamically switch between pure throughput mode and poll based (called 'cpu') mode. Also, for newer chipsets, the timer irq is not needed for throughput mode. Secondly, since we are modifying the irqmask to change between modes, msix is not supported.

If there has been a large amount of time without any burst of network load, the code will transition to pure throughput mode (where each tx/rx/other will cause an interrupt). If bursts of network load occurs, it will transition to poll based mode to help reduce cpu utilization (it will not interrupt on each packet) while maintaining the optimum network bandwidth utilization.

There is no checking of the mac address set on the macvlan. Allowing a misconfiguration to grab packets from the the underlying device or another macvlan. To resolve these problems I update the hash table of macvlans when the mac address of a macvlan changes, and when updating the hash table I verify that the new mac address is usable. The result is well defined and predictable if not perfect handling of mac vlan mac addresses. To keep the code clear I have created a set of hash table maintenance in macvlan so I am not open coding the hash function and the logic needed to update the hash table all over the place.

We should allow receiving frames of up to 1518 bytes in length, instead of 1514. Based on patch written by Ben McKeegan for 2.4.x kernels. It is archived at http://www.candelatech.com/~greear/vlan/howto.html#tulip I've adjusted a few things to make it apply on 2.6.x kernels. Tested on D-Link DFE-570TX quad-fastethernet card.

Problem Description: As the "ppp_mp_explode" function fragments the sk_buff buffer evenly among the PPP channels that are connected to a certain PPP unit to make up a bundle, if we are transmitting using an upper layer protocol that requires an Ack before sending the next packet (like TCP/IP for example), we will have a bandwidth bottleneck on the slowest channel of the bundle. Let's clarify by an example. Let's consider a scenario where we have two PPP links making up a bundle: a slow link (10KB/sec) and a fast link (1000KB/sec) working at the best (full bandwidth). On the top we have a TCP/IP stack sending a 1000 Bytes sk_buff buffer down to the PPP subsystem. The "ppp_mp_explode" function will divide the buffer in two fragments of 500B each (we are neglecting all the headers, crc, flags etc?.). Before the TCP/IP stack sends out the next buffer, it will have to wait for the ACK response from the remote peer, so it will have to wait for both fragments to have been sent over the two PPP links, received by the remote peer and reconstructed. The resulting behaviour is that, rather than having a bundle working @1010KB/sec (the sum of the channels bandwidths), we'll have a bundle working @20KB/sec (the double of the slowest channels bandwidth). Problem Solution: The problem has been solved by redesigning the "ppp_mp_explode" function in such a way to make it split the sk_buff buffer according to the speeds of the underlying PPP channels (the speeds of the serial interfaces respectively attached to the PPP channels). Referring to the above example, the redesigned "ppp_mp_explode" function will now divide the 1000 Bytes buffer into two fragments whose sizes are set according to the speeds of the channels where they are going to be sent on (e.g . 10 Byets on 10KB/sec channel and 990 Bytes on 1000KB/sec channel). The reworked function grants the same performances of the original one in optimal working conditions (i.e. a bundle made up of PPP links all working at the same speed), while greatly improving performances on the bundles made up of channels working at different speeds.

The feature is being enabled for NX3031, NX2031 (old) will be enabled later. This depends on msi-x and compatibility with msi and legacy is maintained by enabling single rx ring.

We simply stop hardware on suspend and start it again on resume. For RGB panels this is trivial, but for SYS panels in deferred io mode this becomes a bit more difficult - we need to wait for a frame end interrupt to make sure the clocks are balanced before stopping the actual hardware.

This patch causes all f_flags changes after file open/creation time to be done under protection of f_lock. This allows the removal of some BKL usage and fixes a number of longstanding (if microscopic) races.

But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

Subsequently, this reduces the number of warnings, too. Thanks to Joe Perches for pointing this out! v3: Ran the whole file through Lindent first... which does most of the work for me. :) Again, thanks to Joe Perches for this. This is my final answer!

As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out wiht the correct hardware checksum. Thanks to Kand Ly for discovering the issue and the coming up with a solution. This patch is based upon his work.

If the case of reset timeout, emac_report_timeout_error() function is called to report an error. The problem is this function uses net_device name to report device related, which is not correct, as a result in the kernel log buffer we see: eth%d: reset timeout The solution is to print device_node full_name instead.

There are times when we'd like to send these packets out without having to configure a vlan on the interface.

This patch changes the behavior: header_size = 8 now passes the header quadlet followed by the timestamp quadlet. When header_size > 8, quadlets are stripped from the payload. The header_size = 4 case remains identical. Since this alters the semantics of the API, the firewire API version needs to be bumped concurrently with this change. This change also refactors the header copying code slightly to be much easier to read.

Therefore prevent requests with wrong tcodes from entering the transaction layer. Maybe fw_send_request should check them itself, but I am not inclined to change it and fw_fill_request from void-valued functions to ones which return error codes and pass those up. Besides, maybe fw_send_request is going to support one more tcode than ioctl_send_request in the future (TCODE_STREAM_DATA).

By changing to an idr we can be safe from counter wrap-around giving two resources the same handle. Furthermore, the deallocation ioctls now check whether the resource to be freed is of the intended type. Signed-off-by: Jay Fenlason Some rework by Stefan R: - The idr API documentation says we get an ID within 0...0x7fffffff. Hence we can rest assured that idr handles fit into cdev handles. - Fix some races. Add a client->in_shutdown flag for this purpose. - Add allocation retry to add_client_resource(). - It is possible to use idr_for_each() in fw_device_op_release(). - Fix ioctl_send_response() regression. - Small style changes.

Instead the caller is required to pass valid parameters. Since one of the callers of fw_core_add_address_handler() is the cdev userspace interface, we now check for valid input. If the client is buggy, we give it a hint with -EINVAL.

Any userspace client and in the future also kernelspace clients can allocate IR DMA contexts for any channel. We don't want them to interfere with each other, hence it is preferable to return -EBUSY if allocation of a second context for a channel is attempted. Notes: - This limitation is OHCI-1394 specific, therefore its proper place of implementation is down in the low-level driver. - Since the ABI simply maps one userspace iso client context to one hardware iso context, this OHCI-1394 limitation alas requires userspace to implement its own multiplexing of iso reception from the same channel and card to multiple clients when needed. - The limitation is independent of channel allocation at the IRM; the latter is really only important for the initiation of iso transmission but not of iso reception. - We don't need to do the same for IT DMA because OHCI-1394 does not have any ties between IT contexts and channels. Only the voluntary channel allocation protocol via the IRM, globally to the FireWire bus, can ensure proper isochronous transmit behaviour anyway.

Only the part of the ABI which enables auto-reallocation and auto-deallocation is included here. This implements ioctls for kernel-assisted allocation of isochronous channels and isochronous bandwidth. The benefits are: - The client does not have to have write access to the /dev/fw* device corresponding to the IRM. - The client does not have to perform reallocation after bus resets. - Channel and bandwidth are deallocated by the kernel if the file is closed before the client deallocated the resources. Thus resources are released even if the client crashes. It is anticipated that future in-kernel code (firewire-core IRM code; the firewire port of firedtv), will use the fw-iso.c portions of this code too.

In case of 1394a bus topologies, the maximum possible speed could be figured out with some effort by evaluation of the remote node's link speed field in the config ROM, the local node's link speed field, and the PHY speeds and topologic information in the local node's or IRM's topology map CSR. However, this does not work in case of 1394b buses. Hence add an ioctl to export the maximum speed which the kernel already determined.

A simplification: - fw_cdev_allocate_iso_resource.channels is now ordered like libdc1394's dc1394_iso_allocate_channel() channels_allowed argument. By the way, I looked closer at cards from NEC, TI, and VIA, and noticed that they all don't implement IEEE 1394a behaviour which is meant to deviate from IEEE 1212's notion of lock compare-swap. This means that we have to do two lock transactions instead of one in many cases where one transaction would already succeed on a fully 1394a compliant IRM.

In specific, if the local device the IRM, it allocates ISO channel 31 and sets the broadcast channel register of all devices on the local bus to BROADCAST_CHANNEL_INITIAL | BROADCAST_CHANNEL_VALID to indicate that channel 31 can be use for broadcast messages. One minor complication is that on startup the local device may become IRM before all the devices on the bus have been enumerated by the stack. Therefore we have to keep a "the local device is IRM" flag and possibly set the broadcast channel register of new devices at enumeration time.

An example policy is to deny write permission by default but grant write permission to files of AV/C video and audio devices and IIDC video devices. The FW_CDEV_IOC_ADD_DESCRIPTOR ioctl could be used to partly subvert such a policy: Find a device file with relaxed permissions, use the ioctl to add a descriptor with AV/C marker to the local node's ROM, thus gain access to the local node's character device file. (This is only possible if there are udev scripts installed which actively relax permissions for known device types and if there is a device of such a type connected.) Accessibility of the local node's device file is relevant to host security if the host contains two or more IEEE 1394 link layer controllers which are plugged into a single bus. Therefore change the ABI to deny FW_CDEV_IOC_ADD_DESCRIPTOR if the file belongs to a remote node. (This change has no impact on known implementers of the ABI: None of them uses the ioctl yet.) Also clarify the documentation: The ioctl affects all local nodes, not just one local node.

They used to return sizeof(struct fw_cdev_send_request *) + data_length which is obviously a failed attempt to emulate the return value of raw1394's respective interface which uses write() instead of ioctl(). However, the first summand, as size of a kernel pointer, is entirely meaningless to clients and the second summand is already known to clients. And the result does not resemble raw1394's write() return code anyway. So simplify it to a constant non-negative value, i.e. 0. The only dangers here would be that future client implementations check for error by ret != 0 instead of ret < 0 when running on top of an old kernel; or that current clients interpret ret = 0 or more as failure. But both are hypothetical cases which don't justify to return irritating values. While we touch this code, also remove "& 0x1f" from tcode in the call of fw_send_request. The tcode cannot be bigger than 0x1f at this point.

In at least one device (a Saitek Cyborg Gold 3D joystick), attempts to read the Configuration string cause the device to stop responding to Control requests. This patch (as1226) adds a quirks flag, telling the kernel not to read a device's Configuration or Interface strings, together with a new quirk for the offending joystick.

The issue is with hardware which needs help conforming to part of the USB 2.0 spec (section 8.5.3.2); some can automagically send a ZLP in response to an unexpected IN, but not all chips will do that. We don't need to check the packet length ourselves the way earlier code did, since the UDC must already check it. But we do need to tell the UDC when it must force a short packet termination of the data stage. (Based on a patch from Aric D.

By default usb-storage sets max_sectors to 240 (i.e., 120 KB) for all devices. But tape drives need a higher limit, since tapes can and do have very large block sizes. Without the ability to transfer an entire large block in a single command, such tapes can't be used. This fixes Bugzilla #12207.

At some point I dropped it, to save the batteries if nothing else. As it turned out, printers exist (e.g. Canon BJC-3000) that need prodding this way or else they stop. This patch restores the old behaviour. If you want to save battery, don't leave jobs in the print queue. I tested this on my printers by printing and examining usbmon traces to make sure status is being requested and printers continue to print. Tuomas Jäntti verified the fix on BJC-3000.

If the device is physically removed whilst the process still has its device node open, then other processes can sucessfully open the now non-existent device's node. I would expect that open() on a device that has been physically removed should return ENODEV. This is manifesting itself with getty on my system. I do the following: 1. set up inittab to spawn getty on ttyUSB0, eg: T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100 2. Plug in USB-serial converter cable 3. Wait for a login prompt on a terminal program attached to the serial cable 4. Login 5. Pull the USB-serial converter cable from the box 6. getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0 can still be opened. 7. Re-insert the USB-serial converter cable 8. You should no longer get a login prompt over the serial cable, as the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is trying to talk to /dev/ttyUSB0. The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return ENODEV after the USB-serial converter has been pulled. The patch was created against 2.6.28.1. I can supply it against something else if needs be. It is fairly simple, so should be OK. I am using a pl2303 device, although I don't think that makes any difference.

But the sat to cypress atacb translation supposed the ->cmnd buffer wasn't modified. This patch makes it set the ->cmnd buffer after scsi_eh_prep_cmnd call. The problem and a fix was reported by Matthieu CASTET It also removes all the hackery fiddling of scsi_cmnd and scsi_eh_save by requesting from scsi_eh_prep_cmnd to prepare a read into ->sense_buffer, which is much more suitable a buffer for HW transfers, then after the command execution the regs read is copied into regs buffer before actual preparation of sense_buffer. Also fix an alien comment character to my utf-8 editor.

It gets invoked when the driver encounters transaction errors on an asynchronous endpoint. On many systems, hardware deficiencies cause such errors to occur if one device is unplugged while the host is communicating with another device. With the patch, the failed transactions are retried and generally succeed the second or third time through. This is based on code originally written by Koichiro Saito.

It makes the following large-scale changes: Remove a bunch of unnecessary #ifdef's from usb_usual.h. Not truly necessary, but it does clean things up. Move the USB device-ID table (which is duplicated between libusual and usb-storage) into its own source file, usual-tables.c, and arrange for this to be linked with either libusual or usb-storage according to whether USB_LIBUSUAL is configured. Add to usual-tables.c a new usb_usual_ignore_device() function to detect whether a particular device needs to be managed by a subdriver and not by the standard handlers in usb-storage. Export a whole bunch of functions in usb-storage, renaming some of them because their names don't already begin with "usb_stor_". These functions will be needed by the new subdriver modules. Split usb-storage's probe routine into two functions. The subdrivers will call the probe1 routine, then fill in their transport and protocol settings, and then call the probe2 routine. Take the default cases and error checking out of get_transport() and get_protocol(), which run during probe1, and instead put a check for invalid transport or protocol values into the probe2 function. Add a new probe routine to be used for standard devices, i.e., those that don't need a subdriver. This new routine checks whether the device should be ignored (because it should be handled by ub or by a subdriver), and if not, calls the probe1 and probe2 functions.

An unexpected complication arises because of DPCM devices, in which one LUN uses the sddr09 transport and one uses the standard CB transport. Since these devices can be used even when USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h require special treatment. If SDDR09 isn't configured then the entries remain in unusual_devs.h; if it is then the entries are present in unusual_sddr09.h instead.

This is correct for OTG hosts, where either SRP or an ID interrupt could turn VBUS on again. However, for non-OTG hosts there's no way to turn VBUS on again, so the host becomes unusable. And the procfs entry which once allowed a manual workaround for this is now gone.

The /dev/ttyUSB0 is not released until being closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is no longer usable by minicom. It is really a mess for a minicom user. This patch also adds the reset_resume callback to make it usable after resuming from STR or hibernation, for generally STR or hibernation will make the vbus of root-hub lost. Finally enable the driver's supports_autosuspend, for the device is in working order with it.

Currently we call usb_set_interface() for every interface in the active configuration; this is to put the interface into the same altsetting as before the reset and to make sure that the host's endpoint state matches the device's endpoint state. However, sending a Set-Interface request is a waste of time if an interface was already in altsetting 0 before the reset, since it is certainly in altsetting 0 afterward. In addition, many devices can't handle Set-Interface requests -- they crash when they receive them. So instead, the patch adds code to check each interface. If the interface wasn't in altsetting 0 before the reset, we go head with the Set-Interface request as before. But if it was then we skip sending the Set-Interface request, and we clear out the host-side endpoint state by calling usb_disable_interface() followed by usb_enable_interface(). The patch also adds a couple of new comments to explain what's going on.

These changes restore the configuration to proper functioning both as a tty and as a console. As Alan notes in that commit, these changes will need to be tweaked when we have a proper console abstraction.

The idea has been verified by the commit 6cd495860901, which leads to a faster boot. But the commit 6cd495860901 has the following drawbacks: 1),only does the quick check in the path of __driver_attach->driver_probe_device, not in other paths; 2),for a matched device and driver, check the same match twice. It is a waste of cpu ,especially for some drivers with long device id table (eg. usb-storage driver). This patch adds a helper of driver_match_device to check the match in all paths, and testes the match only once.

However, silicon IPs for these SoCs are usually shared heavily across a family of processors, even products from different companies. This makes the original simple driver name based matching insufficient, or simply not straight-forward. Introduce a module id table for platform devices, and makes it clear that a platform driver is able to support some shared IP and handle slight differences across different platforms (by 'driver_data'). Module alias is handled automatically when a MODULE_DEVICE_TABLE() is defined. To not disturb the current platform drivers too much, the matched id entry is recorded and can be retrieved by platform_get_device_id().

Koch" Date: Wed, 7 Jan 2009 00:15:39 +0100 Subject: UIO: Add name attributes for mappings and port regions If a UIO device has several memory mappings, it can be difficult for userspace to find the right one. The situation becomes even worse if the UIO driver can handle different versions of a card that have different numbers of mappings. Benedikt Spranger has such cards and pointed this out to me. Thanks, Bene! To address this problem, this patch adds "name" sysfs attributes for each mapping. Userspace can use these to clearly identify each mapping. The name string is optional. If a driver doesn't set it, an empty string will be returned, so this patch won't break existing drivers. The same problem exists for port region information, so a "name" attribute is added there, too. Signed-off-by: Hans J.

"Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei Acked-by: Henrique de Moraes Holschuh Acked-by: David Brownell Signed-off-by: Greg Kroah-Hartman --- arch/mips/basler/excite/excite_iodev.c | 27 ++++++++++++------------ drivers/char/tpm/tpm_atmel.c | 28 +++++++++++++++++-------- drivers/char/tpm/tpm_tis.c | 28 +++++++++++++++++-------- drivers/ide/au1xxx-ide.c | 36 ++++++++++++++++---------------- drivers/mtd/maps/pxa2xx-flash.c | 37 +++++++++++++++++---------------- drivers/mtd/nand/excite_nandflash.c | 25 +++++++++++----------- drivers/mtd/onenand/generic.c | 26 +++++++++++------------ drivers/net/mipsnet.c | 26 ++++++++++++----------- drivers/pcmcia/au1000_generic.c | 37 +++++++++++++++++++++------------ drivers/pcmcia/i82365.c | 28 ++++++++++++++++++------- drivers/pcmcia/m32r_cfc.c | 30 +++++++++++++++++++-------- drivers/pcmcia/m32r_pcc.c | 30 +++++++++++++++++++-------- drivers/pcmcia/sa1100_generic.c | 38 +++++++++++++++++++++++++--------- drivers/pcmcia/tcic.c | 30 +++++++++++++++++++-------- drivers/pcmcia/vrc4171_card.c | 34 +++++++++++++++++++++--------- drivers/scsi/a4000t.c | 26 ++++++++++++----------- drivers/scsi/bvme6000_scsi.c | 26 ++++++++++++----------- drivers/scsi/mvme16x_scsi.c | 26 ++++++++++++----------- drivers/video/au1100fb.c | 31 +++++++++++++-------------- drivers/video/au1200fb.c | 25 ++++++++++++---------- drivers/watchdog/rm9k_wdt.c | 27 +++++++++++------------- 21 files changed, 371 insertions(+), 250 deletions(-) (limited to 'drivers') diff --git a/arch/mips/basler/excite/excite_iodev.c b/arch/mips/basler/excite/excite_iodev.c index a1e3526b4a94..dfbfd7e2ac08 100644 --- a/arch/mips/basler/excite/excite_iodev.c +++ b/arch/mips/basler/excite/excite_iodev.c @@ -33,8 +33,8 @@ static const struct resource *iodev_get_resource(struct platform_device *, const char *, unsigned int);

Now all platform_driver is registered by platform_driver_register, which makes probe()/release()/... of platform_driver passed parameter of platform_device *, so platform driver can get platform_data from platform_device; 2. Other kind of devices do not need to use platform_data, we can decrease size of device if moving it to platform_device. Taking into consideration of thousands of files to be fixed and they can't be finished in one night(maybe it will take a long time), so we keep platform_data in device to allow two kind of cases coexist until all platform devices pass its platfrom data from platform_device->platform_data.

By this way, we can do it for other objects embedded with kobject. 2,It may save several bytes for each instance of struct device.(On my omap3(32bit ARM) based box, can save 8bytes per device object) This patch also introduces dev_set|get_uevent_suppress() helpers to set and query uevent_suppress attribute in case to help kobject as private part of struct device in future.

-- cgit v1.2.3 From ffa6a7054d172a2f57248dff2de600ca795c5656 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Wed, 4 Mar 2009 12:44:00 +0100 Subject: Driver core: Fix device_move() vs. dpm list ordering, v2 dpm_list currently relies on the fact that child devices will be registered after their parents to get a correct suspend order. Using device_move() however destroys this assumption, as an already registered device may be moved under a newly registered one. This patch adds a new argument to device_move(), allowing callers to specify how dpm_list should be adapted.

Vegard Nossum discovered that a poorly written sysfs ->store callback can repeatedly schedule remove callbacks on the same device over and over, e.g. $ while true ; do echo 1 > /sys/devices/.../remove ; done If the 'remove' attribute uses the sysfs_schedule_callback API and also does not protect itself from concurrent accesses, its callback handler will be called multiple times, and will eventually attempt to perform operations on a freed kobject, leading to many problems. Instead of requiring all callers of sysfs_schedule_callback to implement their own synchronization, provide the protection in the infrastructure. Now, sysfs_schedule_callback will only allow one scheduled callback per kobject. On subsequent calls with the same kobject, return -EAGAIN. This is a short term fix. The long term fix is to allow sysfs attributes to remove themselves directly, without any of this callback hokey pokey.

This is automatically handled by pci. Drop it. This might be needed on machines if the BIOS turns intx off during boot. However, there's no evidence of such behavior for ahci and the only such case seems to be ICH5 PATA according to ata_piix. Also, given the way ahci operates, it's highly unlikely BIOS ever disables IRQ for the controller. However, as this change has slight possibility of introducing failure, please schedule it for #upstream.

This feature can reduce total interrupt overhead for RAID setups in some situations, by deferring the interrupt signal until one or both of: a) a specified io_count (completed SATA commands) is achieved, or b) a specified time interval elapses after an IO completion. For now, module parameters are used to set the irq_coalescing_io_count and irq_coalescing_usecs (timeout) globally. These may eventually be supplemented with sysfs attributes, so that thresholds can be set on-the-fly and on a per-chip (or even per-host_controller) basis.

This prevents us from attempting to use dubious multi_count values ad infinitum. Reset dev->multi_count to zero and reprobe it each time through this routine, as it can change on device reset. Also ensure that the reported "maximum" value is valid and is a power of two, and that the reported "count" value is valid and also a power of two.

Open/close on a loop device acquires bd_mutex of the device before acquiring lo_ctl_mutex of the same device. For ioctl(LOOP_CLR_FD) after acquiring lo_ctl_mutex, fput on the backing_file might acquire the bd_mutex of a device, if backing file is a device and this is the last reference to the file being dropped . But it is guaranteed that it is impossible to have a circular list of backing devices.(say loop2->loop1->loop0->loop2 is not possible), which guarantees that this can never deadlock. So this warning should be suppressed. It is very difficult to annotate lockdep not to warn here in the correct way. A simple way to silence lockdep could be to mark the lo_ctl_mutex in ioctl to be a sub class, but this might mask some other real bugs. @@ -1164,7 +1164,7 @@ static int lo_ioctl(struct block_device *bdev, fmode_t mode, struct loop_device *lo = bdev->bd_disk->private_data; int err; - mutex_lock(&lo->lo_ctl_mutex); + mutex_lock_nested(&lo->lo_ctl_mutex, 1); switch (cmd) { case LOOP_SET_FD: err = loop_set_fd(lo, mode, bdev, arg); Or actually marking the bd_mutex after lo_ctl_mutex as a sub class could be a better solution. Luckily it is easy to avoid calling fput on backing file with lo_ctl_mutex held, so no lockdep annotation is required. If you do not like the special handling of the lo_ctl_mutex just for the LOOP_CLR_FD ioctl in lo_ioctl(), the mutex handling could be moved inside each of the individual ioctl handlers and I could send you another patch.

The new addressing scheme makes use of the fact that the actual number of heads is never larger then 15, so 12 bits of the head number can be redefined to be part of the cylinder address.

This patch adds a platform device driver that supports the OpenCores 10/100 Mbps Ethernet MAC. The driver expects three resources: one IORESOURCE_MEM resource defines the memory region for the core's memory-mapped registers while a second IORESOURCE_MEM resource defines the network packet buffer space. The third resource, of type IORESOURCE_IRQ, associates an interrupt with the driver. Signed-off-by: Thierry Reding Acked-by: Florian Fainelli Signed-off-by: David S.

Since the pagefault path determines that the lock order we use has to be mmap_sem -> struct_mutex, we can't allow page faults to occur while the struct_mutex is held. To fix this in pwrite, we first try optimistically to see if we can copy from user without faulting. If it fails, fall back to using get_user_pages to pin the user's memory, and map those pages atomically when copying it to the GPU.

The seq_file API was designed specifically for cases like this and greatly simplifies the process. Also, most of the files in /proc really don't belong there. This patch introduces the infrastructure for putting these into debugfs and exposes all of the proc files in debugfs as well.

however without support for automatic noise immunity, we can sometimes get an interrupt storm. The get_stats() callback reads the counters anyway so we can disable the interrupt for now until ANI is implemented. This fixes the issue reported in http://bugzilla.kernel.org/show_bug.cgi?id=12647.

Currently we have a bug somewhere which triggers this interrupt once in a while. (Depends on the network noise/quality). While this is nonfatal, it scares the hell out of users and we frequently receive bugreports that incorrectly identify this error message as the reason. There's another problem with this. The PHY TX error interrupt is protected with a watchdog that will restart the device if it keeps triggering very often. This is used to fix interrupt storms from completely broken devices. However, this watchdog might trigger in completely normal operation. If the TX capacity of the card is saturated, the likeliness of the watchdog triggering increases, as more TX errors occur. The current threshold for the watchdog is 1000 errors in 15 seconds. This patch adds a workaround for the issue by just enabling the interrupt if debugging is disabled (by Kconfig or by modparam). This has the downside that real fatal PHY TX errors are not caught anymore. But this is nonfatal due to the following reasons: * If the card is not able to transmit anymore, MLME will notice anyway. * I did _never_ see a real fatal PHY TX error in a mainline b43 driver. * It does _not_ result in interrupt storms or something like that. It will simply result in a stalled card. It can be debugged by enabling the debugging module parameter. Signed-off-by: Michael Buesch Signed-off-by: John W.

Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts. Signed-off-by: Johannes Berg Cc: Reinette Chattre Signed-off-by: John W.
