From 66dbc325afcef909043c30e90930a36823fc734c Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Tue, 15 Mar 2011 16:12:09 -0400 Subject: evm: re-release EVM protects a file's security extended attributes(xattrs) against integrity attacks. This patchset provides the framework and an initial method. The initial method maintains an HMAC-sha1 value across the security extended attributes, storing the HMAC value as the extended attribute 'security.evm'. Other methods of validating the integrity of a file's metadata will be posted separately (eg. EVM-digital-signatures). While this patchset does authenticate the security xattrs, and cryptographically binds them to the inode, coming extensions will bind other directory and inode metadata for more complete protection. To help simplify the review and upstreaming process, each extension will be posted separately (eg. IMA-appraisal, IMA-appraisal-directory). For a general overview of the proposed Linux integrity subsystem, refer to Dave Safford's whitepaper: http://downloads.sf.net/project/linux-ima/linux-ima/Integrity_overview.pdf. EVM depends on the Kernel Key Retention System to provide it with a trusted/encrypted key for the HMAC-sha1 operation. The key is loaded onto the root's keyring using keyctl. Until EVM receives notification that the key has been successfully loaded onto the keyring (echo 1 > /evm), EVM can not create or validate the 'security.evm' xattr, but returns INTEGRITY_UNKNOWN. Loading the key and signaling EVM should be done as early as possible. Normally this is done in the initramfs, which has already been measured as part of the trusted boot. For more information on creating and loading existing trusted/encrypted keys, refer to Documentation/keys-trusted-encrypted.txt. A sample dracut patch, which loads the trusted/encrypted key and enables EVM, is available from http://linux-ima.sourceforge.net/#EVM. Based on the LSMs enabled, the set of EVM protected security xattrs is defined at compile. EVM adds the following three calls to the existing security hooks: evm_inode_setxattr(), evm_inode_post_setxattr(), and evm_inode_removexattr. To initialize and update the 'security.evm' extended attribute, EVM defines three calls: evm_inode_post_init(), evm_inode_post_setattr() and evm_inode_post_removexattr() hooks. To verify the integrity of a security xattr, EVM exports evm_verifyxattr(). Changelog v7: - Fixed URL in EVM ABI documentation Changelog v6: (based on Serge Hallyn's review) - fix URL in patch description - remove evm_hmac_size definition - use SHA1_DIGEST_SIZE (removed both MAX_DIGEST_SIZE and evm_hmac_size) - moved linux include before other includes - test for crypto_hash_setkey failure - fail earlier for invalid key - clear entire encrypted key, even on failure - check xattr name length before comparing xattr names Changelog: - locking based on i_mutex, remove evm_mutex - using trusted/encrypted keys for storing the EVM key used in the HMAC-sha1 operation. - replaced crypto hash with shash (Dmitry Kasatkin) - support for additional methods of verifying the security xattrs (Dmitry Kasatkin) - iint not allocated for all regular files, but only for those appraised - Use cap_sys_admin in lieu of cap_mac_admin - Use __vfs_setxattr_noperm(), without permission checks, from EVM Signed-off-by: Mimi Zohar Acked-by: Serge Hallyn --- Documentation/ABI/testing/evm | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 Documentation/ABI/testing/evm (limited to 'Documentation') diff --git a/Documentation/ABI/testing/evm b/Documentation/ABI/testing/evm new file mode 100644 index 000000000000..8374d4557e5d --- /dev/null +++ b/Documentation/ABI/testing/evm @@ -0,0 +1,23 @@ +What: security/evm +Date: March 2011 +Contact: Mimi Zohar +Description: + EVM protects a file's security extended attributes(xattrs) + against integrity attacks.

With its shared instruction cache there is a chance of generating an excessive number of cache cross-invalidates when running specific workloads on the cores of a compute module. This excessive amount of cross-invalidations can be observed if cache lines backed by shared physical memory alias in bits [14:12] of their virtual addresses, as those bits are used for the index generation. This patch addresses the issue by clearing all the bits in the [14:12] slice of the file mapping's virtual address at generation time, thus forcing those bits the same for all mappings of a single shared library across processes and, in doing so, avoids instruction cache aliases. It also adds the command line option "align_va_addr=(32|64|on|off)" with which virtual address alignment can be enabled for 32-bit or 64-bit x86 individually, or both, or be completely disabled. This change leaves virtual region address allocation on other families and/or vendors unaffected.

Inspecting the code, it is not immediately obvious that the functions sleep at all, as they run inside a spin_lock_irqsave, but under some conditions they can drop the lock and turn on irqs. If a driver incorrectly calls the pm_runtime apis, it can cause sleeping and irq processing when it expects to stay in atomic context. Add might_sleep_if to the majority of the __pm_runtime_* entry points to enforce correct usage. Add pm_runtime_put_sync_autosuspend to the list of functions that can be called in atomic context.

Encapsulating this notion seems preferable to open-coding the test all over the place. Signed-off-by: Alan Stern Acked-by: Greg Kroah-Hartman Signed-off-by: Rafael J.

Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.

It can operate without this shadow, but then it cannot tell which pixels have changed, and must send all. Saves host memory, but worsens the USB 2.0 bus bottleneck. This option allows users in very low memory situations (e.g. bifferboard) to optionally turn off this shadow framebuffer.

Also, print a single warning that data=journal implies that delayed allocation is not on by default (since it's not supported), and furthermore that O_DIRECT is not supported. Improve the text in Documentation/filesystems/ext4.txt so this is clear there as well. Similarly, if the dioread_nolock mount option is specified when the file system block size != PAGE_SIZE, fail the mount instead of printing a warning message and ignoring the mount option.

Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

At the same time, the irq parameter being invalid specifies that the mpu401 code has to work without an interrupt allocated by the caller. This implies that, if there is an interrupt and it is allocated by the caller, the irq parameter must be set to a valid-looking number which then isn't actually used. With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value, which forces us to handle the parameters differently. This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the device interrupt is handled by the caller, and makes the allocation of the interrupt to depend only on the irq parameter. As suggested by Takashi, the irq_flags parameter was dropped because, when used, it had the constant value IRQF_DISABLED.

In other words, the operational setting of the "accept_ra" sysctl is used. The change also makes the special "Hybrid Router" forwarding mode ("forwarding" sysctl set to 2) operate exactly the same as the standard Router mode (forwarding=1). The only difference between the two was that RSes was being sent in the Hybrid Router mode only. The sysctl documentation describing the special Hybrid Router mode has therefore been removed. Rationale for the change: Currently, the value of forwarding sysctl is the only thing determining whether or not to send RSes. If it has the value 0 or 2, they are sent, otherwise they are not. This leads to inconsistent behaviour in the following cases: * accept_ra=0, forwarding=0 * accept_ra=0, forwarding=2 * accept_ra=1, forwarding=2 * accept_ra=2, forwarding=1 In the first three cases, the kernel will send RSes, even though it will not accept any RAs received in reply. In the last case, it will not send any RSes, even though it will accept and process any RAs received. (Most routers will send unsolicited RAs periodically, so suppressing RSes in the last case will merely delay auto-configuration, not prevent it.) Also, it is my opinion that having the forwarding sysctl control RS sending behaviour (completely independent of whether RAs are being accepted or not) is simply not what most users would intuitively expect to be the case.

This is to take advantage of the features that x2apic brings in. Some of the OEM platforms are running into issues because of this, as their bios is not x2apic aware. For example, this was resulting in interrupt migration issues on one of the platforms. Also if the BIOS SMI handling uses APIC interface to send SMI's, then the BIOS need to be aware of x2apic mode that OS has enabled. On some of these platforms, BIOS doesn't have a HW mechanism to turnoff the x2apic feature to prevent OS from enabling it. To resolve this mess, recent changes to the VT-d2 specification: http://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf includes a mechanism that provides BIOS a way to request system software to opt out of enabling x2apic mode. Look at the x2apic optout flag in the DMAR tables before enabling the x2apic mode in the platform. Also print a warning that we have disabled x2apic based on the BIOS request. Kernel boot parameter "intremap=no_x2apic_optout" can be used to override the BIOS x2apic optout request.

That worked, but required hwspinlocks drivers to do a bit extra work when they were probed/removed. This patch changes hwspin_lock_{un}register() to allow a bank of hwspinlocks to be {un}registered in a single invocation. A new 'struct hwspinlock_device', which contains an array of 'struct hwspinlock's is now being passed to the core upon registration (so instead of wrapping each struct hwspinlock, a priv member has been added to allow drivers to piggyback their private data with each hwspinlock). While at it, several per-lock members were moved to be per-device: 1. struct device *dev 2. struct hwspinlock_ops *ops In addition, now that the array of locks is handled by the core, there's no reason to maintain a per-lock 'int id' member: the id of the lock anyway equals to its index in the bank's array plus the bank's base_id. Remove this per-lock id member too, and instead use a simple pointers arithmetic to derive it. As a result of this change, hwspinlocks drivers are now simpler and smaller (about %20 code reduction) and the memory footprint of the hwspinlock framework is reduced.

the hard VCPU count limit The patch raises the hard limit of VCPU count to 254. This will allow developers to easily work on scalability and will allow users to test high VCPU setups easily without patching the kernel. To prevent possible issues with current setups, KVM_CAP_NR_VCPUS now returns the recommended VCPU limit (which is still 64) - this should be a safe value for everybody, while a new KVM_CAP_MAX_VCPUS returns the hard limit which is now 254.

When set to 0, the non-snooping mode is used with the traffic control bit is set in each stream control register. This may allow better operations in the low power mode, but the actual implementation is depending pretty much on the chipset. As already implemented, more or less each chipset has own snoop-control register bit. Now this setup refers to the snoop option, too. Also, a new VIA chipset may require the non-snooping mode when set so in BIOS. In such a case, the option value is overridden. As default, it's still set to snoop=1 for keeping the same behavior as before. In near future, it'll be set to 0 as default after checking it works in every system well.

McKenney" Date: Mon, 27 Jun 2011 00:17:43 -0700 Subject: rcu: Simplify quiescent-state accounting There is often a delay between the time that a CPU passes through a quiescent state and the time that this quiescent state is reported to the RCU core. It is quite possible that the grace period ended before the quiescent state could be reported, for example, some other CPU might have deduced that this CPU passed through dyntick-idle mode. It is critically important that quiescent state be counted only against the grace period that was in effect at the time that the quiescent state was detected. Previously, this was handled by recording the number of the last grace period to complete when passing through a quiescent state. The RCU core then checks this number against the current value, and rejects the quiescent state if there is a mismatch. However, one additional possibility must be accounted for, namely that the quiescent state was recorded after the prior grace period completed but before the current grace period started. In this case, the RCU core must reject the quiescent state, but the recorded number will match. This is handled when the CPU becomes aware of a new grace period -- at that point, it invalidates any prior quiescent state. This works, but is a bit indirect. The new approach records the current grace period, and the RCU core checks to see (1) that this is still the current grace period and (2) that this grace period has not yet ended. This approach simplifies reasoning about correctness, and this commit changes over to this new approach. Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.

Instead, we hold three locks, one of which might be RCU related. +And maybe that lock really does protect this reference. If so, the fix +is to inform RCU, perhaps by changing __cfq_exit_single_io_context() to +take the struct request_queue "q" from cfq_exit_queue() as an argument, +which would permit us to invoke rcu_dereference_protected as follows: + + if (rcu_dereference_protected(ioc->ioc_data, + lockdep_is_held(&q->queue_lock)) == cic) { + +With this change, there would be no lockdep-RCU splat emitted if this +code was invoked either from within an RCU read-side critical section +or with the ->queue_lock held.

In this case, the critical section must span the use of the +return value from rcu_dereference(), or at least until there is some +reference count incremented or some such. One way to handle this is to +add rcu_read_lock() and rcu_read_unlock() as follows: + + rcu_read_lock(); + if (rcu_dereference(ioc->ioc_data) == cic) { + spin_lock(&ioc->lock); + rcu_assign_pointer(ioc->ioc_data, NULL); + spin_unlock(&ioc->lock); + } + rcu_read_unlock(); + +With this change, the rcu_dereference() is always within an RCU +read-side critical section, which again would have suppressed the +above lockdep-RCU splat. + +But in this particular case, we don't actually deference the pointer +returned from rcu_dereference(). Instead, that pointer is just compared +to the cic pointer, which means that the rcu_dereference() can be replaced +by rcu_access_pointer() as follows: + + if (rcu_access_pointer(ioc->ioc_data) == cic) { + +Because it is legal to invoke rcu_access_pointer() without protection, +this change would also suppress the above lockdep-RCU splat. -- cgit v1.2.3 From 4b801bc969364a980c1366e48155d1a29d20661b Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 29 Sep 2011 16:04:40 +0200 Subject: mac80211: document client powersave With the addition of uAPSD and driver buffering the powersave handling has gotten quite complex.

If this flag is set, + * mac80211 expects the driver to handle most of the state machine for + * powersaving clients and will ignore the PM bit in incoming frames. + * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of + * stations' powersave transitions.

When a + * station goes to sleep, we will stop transmitting to it. There is, + * however, a race condition: a station might go to sleep while there is + * data buffered on hardware queues. If the device has support for this + * it will reject frames, and the driver should give the frames back to + * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will + * cause mac80211 to retry the frame when the station wakes up. The + * driver is also notified of powersave transitions by calling its + * @sta_notify callback. + * + * When the station is asleep, it has three choices: it can wake up, + * it can PS-Poll, or it can possibly start a uAPSD service period. + * Waking up is implemented by simply transmitting all buffered (and + * filtered) frames to the station. This is the easiest case. When + * the station sends a PS-Poll or a uAPSD trigger frame, mac80211 + * will inform the driver of this with the @allow_buffered_frames + * callback; this callback is optional. mac80211 will then transmit + * the frames as usual and set the %IEEE80211_TX_CTL_POLL_RESPONSE + * on each frame. The last frame in the service period (or the only + * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to + * indicate that it ends the service period; as this frame must have + * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS. + * When TX status is reported for this frame, the service period is + * marked has having ended and a new one can be started by the peer. + * + * Another race condition can happen on some devices like iwlwifi + * when there are frames queued for the station and it wakes up + * or polls; the frames that are already queued could end up being + * transmitted first instead, causing reordering and/or wrong + * processing of the EOSP. The cause is that allowing frames to be + * transmitted to a certain station is out-of-band communication to + * the device. To allow this problem to be solved, the driver can + * call ieee80211_sta_block_awake() if frames are buffered when it + * is notified that the station went to sleep. When all these frames + * have been filtered (see above), it must call the function again + * to indicate that the station is no longer blocked. + * + * If the driver buffers frames in the driver for aggregation in any + * way, it must use the ieee80211_sta_set_buffered() call when it is + * notified of the station going to sleep to inform mac80211 of any + * TIDs that have frames buffered. Note that when a station wakes up + * this information is reset (hence the requirement to call it when + * informed of the station going to sleep). Then, when a service + * period starts for any reason, @release_buffered_frames is called + * with the number of frames to be released and which TIDs they are + * to come from. In this case, the driver is responsible for setting + * the EOSP (for uAPSD) and MORE_DATA bits in the released frames, + * to help the @more_data paramter is passed to tell the driver if + * there is more data on other TIDs -- the TIDs to release frames + * from are ignored since mac80211 doesn't know how many frames the + * buffers for those TIDs contain. + * + * If the driver also implement GO mode, where absence periods may + * shorten service periods (or abort PS-Poll responses), it must + * filter those response frames except in the case of frames that + * are buffered in the driver -- those must remain buffered to avoid + * reordering.

There are different kinds of FPGAs used on the boards, but only two are currently standard: "pixis", "ngpixis", and "qixis". Although there are minor differences among the boards that have one kind of FPGA, most of the functionality is the same, so it makes sense to create common compatibility strings. We also need to update the P1022DS platform file, because the compatible string for its PIXIS node has changed. This means that older kernels are not compatible with newer device trees. This is not a real problem, however, since that particular function doesn't work anyway. When the DIU is active, the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped device.

These are devices that control different aspects of package pins. Currently it handles pinmuxing, i.e. assigning electronic functions to groups of pins on primarily PGA and BGA type of chip packages which are common in embedded systems. The plan is to also handle other I/O pin control aspects such as biasing, driving, input properties such as schmitt-triggering, load capacitance etc within this subsystem, to remove a lot of ARM arch code as well as feature-creepy GPIO drivers which are implementing the same thing over and over again. This is being done to depopulate the arch/arm/* directory of such custom drivers and try to abstract the infrastructure they all need. See the Documentation/pinctrl.txt file that is part of this patch for more details. ChangeLog v1->v2: - Various minor fixes from Joe's and Stephens review comments - Added a pinmux_config() that can invoke custom configuration with arbitrary data passed in or out to/from the pinmux driver ChangeLog v2->v3: - Renamed subsystem folder to "pinctrl" since we will likely want to keep other pin control such as biasing in this subsystem too, so let us keep to something generic even though we're mainly doing pinmux now. - As a consequence, register pins as an abstract entity separate from the pinmux. The muxing functions will claim pins out of the pin pool and make sure they do not collide. Pins can now be named by the pinctrl core. - Converted the pin lookup from a static array into a radix tree, I agreed with Grant Likely to try to avoid any static allocation (which is crap for device tree stuff) so I just rewrote this to be dynamic, just like irq number descriptors. The platform-wide definition of number of pins goes away - this is now just the sum total of the pins registered to the subsystem. - Make sure mappings with only a function name and no device works properly. ChangeLog v3->v4: - Define a number space per controller instead of globally, Stephen and Grant requested the same thing so now maps need to define target controller, and the radix tree of pin descriptors is a property on each pin controller device. - Add a compulsory pinctrl device entry to the pinctrl mapping table. This must match the pinctrl device, like "pinctrl.0" - Split the file core.c in two: core.c and pinmux.c where the latter carry all pinmux stuff, the core is for generic pin control, and use local headers to access functionality between files. It is now possible to implement a "blank" pin controller without pinmux capabilities. This split will make new additions like pindrive.c, pinbias.c etc possible for combined drivers and chunks of functionality which is a GoodThing(TM). - Rewrite the interaction with the GPIO subsystem - the pin controller descriptor now handles this by defining an offset into the GPIO numberspace for its handled pin range. This is used to look up the apropriate pin controller for a GPIO pin. Then that specific GPIO range is matched 1-1 for the target controller instance. - Fixed a number of review comments from Joe Perches. - Broke out a header file pinctrl.h for the core pin handling stuff that will be reused by other stuff than pinmux. - Fixed some erroneous EXPORT() stuff. - Remove mispatched U300 Kconfig and Makefile entries - Fixed a number of review comments from Stephen Warren, not all of them - still WIP. But I think the new mapping that will specify which function goes to which pin mux controller address 50% of your concerns (else beat me up). ChangeLog v4->v5: - Defined a "position" for each function, so the pin controller now tracks a function in a certain position, and the pinmux maps define what position you want the function in. (Feedback from Stephen Warren and Sascha Hauer). - Since we now need to request a combined function+position from the machine mapping table that connect mux settings to drivers, it was extended with a position field and a name field. The name field is now used if you e.g. need to switch between two mux map settings at runtime. - Switched from a class device to using struct bus_type for this subsystem. Verified sysfs functionality: seems to work fine. (Feedback from Arnd Bergmann and Greg Kroah-Hartman) - Define a per pincontroller list of GPIO ranges from the GPIO pin space that can be handled by the pin controller. These can be added one by one at runtime. (Feedback from Barry Song) - Expanded documentation of regulator_[get|enable|disable|put] semantics. - Fixed a number of review comments from Barry Song. (Thanks!) ChangeLog v5->v6: - Create an abstract pin group concept that can sort pins into named and enumerated groups no matter what the use of these groups may be, one possible usecase is a group of pins being muxed in or so. The intention is however to also use these groups for other pin control activities. - Make it compulsory for pinmux functions to associate with at least one group, so the abstract pin group concept is used to define the groups of pins affected by a pinmux function. The pinmux driver interface has been altered so as to enforce a function to list applicable groups per function. - Provide an optional .group entry in the pinmux machine map so the map can select beteween different available groups to be used with a certain function. - Consequent changes all over the place so that e.g. debugfs present reasonable information about the world. - Drop the per-pin mux (*config) function in the pinmux_ops struct - I was afraid that this would start to be used for things totally unrelated to muxing, we can introduce that to the generic struct pinctrl_ops if needed. I want to keep muxing orthogonal to other pin control subjects and not mix these things up. ChangeLog v6->v7: - Make it possible to have several map entries matching the same device, pin controller and function, but using a different group, and alter the semantics so that pinmux_get() will pick all matching map entries, and store the associated groups in a list. The list will then be iterated over at pinmux_enable()/pinmux_disable() and corresponding driver functions called for each defined group. Notice that you're only allowed to map multiple *groups* to the same { device, pin controller, function } triplet, attempts to map the same device to multiple pin controllers will for example fail. This is hopefully the crucial feature requested by Stephen Warren. - Add a pinmux hogging field to the pinmux mapping entries, and enable the pinmux core to hog pinmux map entries. This currently only works for pinmuxes without assigned devices as it looks now, but with device trees we can look up the corresponding struct device * entries when we register the pinmux driver, and have it hog each pinmux map in turn, for a simple approach to non-dynamic pin muxing. This addresses an issue from Grant Likely that the machine should take care of as much of the pinmux setup as possible, not the devices. By supplying a list of hogs, it can now instruct the core to take care of any static mappings. - Switch pinmux group retrieveal function to grab an array of strings representing the groups rather than an array of unsigned and rewrite accordingly. - Alter debugfs to show the grouplist handled by each pinmux. Also add a list of hogs. - Dynamically allocate a struct pinmux at pinmux_get() and free it at pinmux_put(), then add these to the global list of pinmuxes active as we go along. - Go over the list of pinmux maps at pinmux_get() time and repeatedly apply matches. - Retrieve applicable groups per function from the driver as a string array rather than a unsigned array, then lookup the enumerators. - Make the device to pinmux map a singleton - only allow the mapping table to be registered once and even tag the registration function with __init so it surely won't be abused. - Create a separate debugfs file to view the pinmux map at runtime. - Introduce a spin lock to the pin descriptor struct, lock it when modifying pin status entries. Reported by Stijn Devriendt. - Fix up the documentation after review from Stephen Warren. - Let the GPIO ranges give names as const char * instead of some fixed-length string. - add a function to unregister GPIO ranges to mirror the registration function. - Privatized the struct pinctrl_device and removed it from the API, the drivers do not need to know the members of this struct. It is now in the local header "core.h". - Rename the concept of "anonymous" mux maps to "system" muxes and add convenience macros and documentation. ChangeLog v7->v8: - Delete the leftover pinmux_config() function from the header. - Fix a race condition found by Stijn Devriendt in pin_request() ChangeLog v8->v9: - Drop the bus_type and the sysfs attributes and all, we're not on the clear about how this should be used for e.g. userspace interfaces so let us save this for the future. - Use the right name in MAINTAINERS, PIN CONTROL rather than PINMUX - Don't kfree() the device state holder, let the .remove() callback handle this. - Fix up numerous kerneldoc headers to have one line for the function description and more verbose documentation below the parameters ChangeLog v9->v10: - pinctrl: EXPORT_SYMBOL needs export.h, folded in a patch from Steven Rothwell - fix pinctrl_register error handling, folded in a patch from Axel Lin - Various fixes to documentation text so that it's consistent. - Removed pointless comment from drivers/Kconfig - Removed dependency on SYSFS since we removed the bus in v9. - Renamed hopelessly abbreviated pctldev_* functions to the more verbose pinctrl_dev_* - Drop mutex properly when looking up GPIO ranges - Return NULL instead of ERR_PTR() errors on registration of pin controllers, using cast pointers is fragile. We can live without the detailed error codes for sure.

This pin space may + be sparse - i.e. there may be gaps in the space with numbers where no + pin exists. + +When a PIN CONTROLLER is instatiated, it will register a descriptor to the +pin control framework, and this descriptor contains an array of pin descriptors +describing the pins handled by this specific pin controller. + +Here is an example of a PGA (Pin Grid Array) chip seen from underneath: + + A B C D E F G H + + 8 o o o o o o o o + + 7 o o o o o o o o + + 6 o o o o o o o o + + 5 o o o o o o o o + + 4 o o o o o o o o + + 3 o o o o o o o o + + 2 o o o o o o o o + + 1 o o o o o o o o + +To register a pin controller and name all the pins on this package we can do +this in our driver: + +#include + +const struct pinctrl_pin_desc __refdata foo_pins[] = { + PINCTRL_PIN(0, "A1"), + PINCTRL_PIN(1, "A2"), + PINCTRL_PIN(2, "A3"), + ... + PINCTRL_PIN(61, "H6"), + PINCTRL_PIN(62, "H7"), + PINCTRL_PIN(63, "H8"), +}; + +static struct pinctrl_desc foo_desc = { + .name = "foo", + .pins = foo_pins, + .npins = ARRAY_SIZE(foo_pins), + .maxpin = 63, + .owner = THIS_MODULE, +}; + +int __init foo_probe(void) +{ + struct pinctrl_dev *pctl; + + pctl = pinctrl_register(&foo_desc, , NULL); + if (IS_ERR(pctl)) + pr_err("could not register foo pin driver\n"); +} + +Pins usually have fancier names than this. You can find these in the dataheet +for your chip. Notice that the core pinctrl.h file provides a fancy macro +called PINCTRL_PIN() to create the struct entries. As you can see I enumerated +the pins from 0 in the upper left corner to 63 in the lower right corner, +this enumeration was arbitrarily chosen, in practice you need to think +through your numbering system so that it matches the layout of registers +and such things in your driver, or the code may become complicated. You must +also consider matching of offsets to the GPIO ranges that may be handled by +the pin controller. + +For a padring with 467 pads, as opposed to actual pins, I used an enumeration +like this, walking around the edge of the chip, which seems to be industry +standard too (all these pads had names, too): + + + 0 ..... 104 + 466 105 + . . + . . + 358 224 + 357 .... 225 + + +Pin groups +========== + +Many controllers need to deal with groups of pins, so the pin controller +subsystem has a mechanism for enumerating groups of pins and retrieving the +actual enumerated pins that are part of a certain group. + +For example, say that we have a group of pins dealing with an SPI interface +on { 0, 8, 16, 24 }, and a group of pins dealing with an I2C interface on pins +on { 24, 25 }. + +These two groups are presented to the pin control subsystem by implementing +some generic pinctrl_ops like this: + +#include + +struct foo_group { + const char *name; + const unsigned int *pins; + const unsigned num_pins; +}; + +static unsigned int spi0_pins[] = { 0, 8, 16, 24 }; +static unsigned int i2c0_pins[] = { 24, 25 }; + +static const struct foo_group foo_groups[] = { + { + .name = "spi0_grp", + .pins = spi0_pins, + .num_pins = ARRAY_SIZE(spi0_pins), + }, + { + .name = "i2c0_grp", + .pins = i2c0_pins, + .num_pins = ARRAY_SIZE(i2c0_pins), + }, +}; + + +static int foo_list_groups(struct pinctrl_dev *pctldev, unsigned selector) +{ + if (selector >= ARRAY_SIZE(foo_groups)) + return -EINVAL; + return 0; +} + +static const char *foo_get_group_name(struct pinctrl_dev *pctldev, + unsigned selector) +{ + return foo_groups[selector].name; +} + +static int foo_get_group_pins(struct pinctrl_dev *pctldev, unsigned selector, + unsigned ** const pins, + unsigned * const num_pins) +{ + *pins = (unsigned *) foo_groups[selector].pins; + *num_pins = foo_groups[selector].num_pins; + return 0; +} + +static struct pinctrl_ops foo_pctrl_ops = { + .list_groups = foo_list_groups, + .get_group_name = foo_get_group_name, + .get_group_pins = foo_get_group_pins, +}; + + +static struct pinctrl_desc foo_desc = { + ... + .pctlops = &foo_pctrl_ops, +}; + +The pin control subsystem will call the .list_groups() function repeatedly +beginning on 0 until it returns non-zero to determine legal selectors, then +it will call the other functions to retrieve the name and pins of the group. +Maintaining the data structure of the groups is up to the driver, this is +just a simple example - in practice you may need more entries in your group +structure, for example specific register ranges associated with each group +and so on. + + +Interaction with the GPIO subsystem +=================================== + +The GPIO drivers may want to perform operations of various types on the same +physical pins that are also registered as pin controller pins. + +Since the pin controller subsystem have its pinspace local to the pin +controller we need a mapping so that the pin control subsystem can figure out +which pin controller handles control of a certain GPIO pin. Since a single +pin controller may be muxing several GPIO ranges (typically SoCs that have +one set of pins but internally several GPIO silicon blocks, each modeled as +a struct gpio_chip) any number of GPIO ranges can be added to a pin controller +instance like this: + +struct gpio_chip chip_a; +struct gpio_chip chip_b; + +static struct pinctrl_gpio_range gpio_range_a = { + .name = "chip a", + .id = 0, + .base = 32, + .npins = 16, + .gc = &chip_a; +}; + +static struct pinctrl_gpio_range gpio_range_a = { + .name = "chip b", + .id = 0, + .base = 48, + .npins = 8, + .gc = &chip_b; +}; + + +{ + struct pinctrl_dev *pctl; + ... + pinctrl_add_gpio_range(pctl, &gpio_range_a); + pinctrl_add_gpio_range(pctl, &gpio_range_b); +} + +So this complex system has one pin controller handling two different +GPIO chips. Chip a has 16 pins and chip b has 8 pins. They are mapped in +the global GPIO pin space at: + +chip a: [32 .. 47] +chip b: [48 .. 55] + +When GPIO-specific functions in the pin control subsystem are called, these +ranges will be used to look up the apropriate pin controller by inspecting +and matching the pin to the pin ranges across all controllers. When a +pin controller handling the matching range is found, GPIO-specific functions +will be called on that specific pin controller. + +For all functionalities dealing with pin biasing, pin muxing etc, the pin +controller subsystem will subtract the range's .base offset from the passed +in gpio pin number, and pass that on to the pin control driver, so the driver +will get an offset into its handled number range. Further it is also passed +the range ID value, so that the pin controller knows which range it should +deal with. + +For example: if a user issues pinctrl_gpio_set_foo(50), the pin control +subsystem will find that the second range on this pin controller matches, +subtract the base 48 and call the +pinctrl_driver_gpio_set_foo(pinctrl, range, 2) where the latter function has +this signature: + +int pinctrl_driver_gpio_set_foo(struct pinctrl_dev *pctldev, + struct pinctrl_gpio_range *rangeid, + unsigned offset); + +Now the driver knows that we want to do some GPIO-specific operation on the +second GPIO range handled by "chip b", at offset 2 in that specific range. + +(If the GPIO subsystem is ever refactored to use a local per-GPIO controller +pin space, this mapping will need to be augmented accordingly.) + + +PINMUX interfaces +================= + +These calls use the pinmux_* naming prefix. No other calls should use that +prefix. + + +What is pinmuxing? +================== + +PINMUX, also known as padmux, ballmux, alternate functions or mission modes +is a way for chip vendors producing some kind of electrical packages to use +a certain physical pin (ball, pad, finger, etc) for multiple mutually exclusive +functions, depending on the application. By "application" in this context +we usually mean a way of soldering or wiring the package into an electronic +system, even though the framework makes it possible to also change the function +at runtime. + +Here is an example of a PGA (Pin Grid Array) chip seen from underneath: + + A B C D E F G H + +---+ + 8 | o | o o o o o o o + | | + 7 | o | o o o o o o o + | | + 6 | o | o o o o o o o + +---+---+ + 5 | o | o | o o o o o o + +---+---+ +---+ + 4 o o o o o o | o | o + | | + 3 o o o o o o | o | o + | | + 2 o o o o o o | o | o + +-------+-------+-------+---+---+ + 1 | o o | o o | o o | o | o | + +-------+-------+-------+---+---+ + +This is not tetris. The game to think of is chess. Not all PGA/BGA packages +are chessboard-like, big ones have "holes" in some arrangement according to +different design patterns, but we're using this as a simple example. Of the +pins you see some will be taken by things like a few VCC and GND to feed power +to the chip, and quite a few will be taken by large ports like an external +memory interface. The remaining pins will often be subject to pin multiplexing. + +The example 8x8 PGA package above will have pin numbers 0 thru 63 assigned to +its physical pins. It will name the pins { A1, A2, A3 ... H6, H7, H8 } using +pinctrl_register_pins() and a suitable data set as shown earlier. + +In this 8x8 BGA package the pins { A8, A7, A6, A5 } can be used as an SPI port +(these are four pins: CLK, RXD, TXD, FRM). In that case, pin B5 can be used as +some general-purpose GPIO pin. However, in another setting, pins { A5, B5 } can +be used as an I2C port (these are just two pins: SCL, SDA). Needless to say, +we cannot use the SPI port and I2C port at the same time. However in the inside +of the package the silicon performing the SPI logic can alternatively be routed +out on pins { G4, G3, G2, G1 }. + +On the botton row at { A1, B1, C1, D1, E1, F1, G1, H1 } we have something +special - it's an external MMC bus that can be 2, 4 or 8 bits wide, and it will +consume 2, 4 or 8 pins respectively, so either { A1, B1 } are taken or +{ A1, B1, C1, D1 } or all of them. If we use all 8 bits, we cannot use the SPI +port on pins { G4, G3, G2, G1 } of course. + +This way the silicon blocks present inside the chip can be multiplexed "muxed" +out on different pin ranges. Often contemporary SoC (systems on chip) will +contain several I2C, SPI, SDIO/MMC, etc silicon blocks that can be routed to +different pins by pinmux settings. + +Since general-purpose I/O pins (GPIO) are typically always in shortage, it is +common to be able to use almost any pin as a GPIO pin if it is not currently +in use by some other I/O port. + + +Pinmux conventions +================== + +The purpose of the pinmux functionality in the pin controller subsystem is to +abstract and provide pinmux settings to the devices you choose to instantiate +in your machine configuration. It is inspired by the clk, GPIO and regulator +subsystems, so devices will request their mux setting, but it's also possible +to request a single pin for e.g. GPIO. + +Definitions: + +- FUNCTIONS can be switched in and out by a driver residing with the pin + control subsystem in the drivers/pinctrl/* directory of the kernel. The + pin control driver knows the possible functions. In the example above you can + identify three pinmux functions, one for spi, one for i2c and one for mmc. + +- FUNCTIONS are assumed to be enumerable from zero in a one-dimensional array. + In this case the array could be something like: { spi0, i2c0, mmc0 } + for the three available functions. + +- FUNCTIONS have PIN GROUPS as defined on the generic level - so a certain + function is *always* associated with a certain set of pin groups, could + be just a single one, but could also be many. In the example above the + function i2c is associated with the pins { A5, B5 }, enumerated as + { 24, 25 } in the controller pin space. + + The Function spi is associated with pin groups { A8, A7, A6, A5 } + and { G4, G3, G2, G1 }, which are enumerated as { 0, 8, 16, 24 } and + { 38, 46, 54, 62 } respectively. + + Group names must be unique per pin controller, no two groups on the same + controller may have the same name. + +- The combination of a FUNCTION and a PIN GROUP determine a certain function + for a certain set of pins. The knowledge of the functions and pin groups + and their machine-specific particulars are kept inside the pinmux driver, + from the outside only the enumerators are known, and the driver core can: + + - Request the name of a function with a certain selector (>= 0) + - A list of groups associated with a certain function + - Request that a certain group in that list to be activated for a certain + function + + As already described above, pin groups are in turn self-descriptive, so + the core will retrieve the actual pin range in a certain group from the + driver. + +- FUNCTIONS and GROUPS on a certain PIN CONTROLLER are MAPPED to a certain + device by the board file, device tree or similar machine setup configuration + mechanism, similar to how regulators are connected to devices, usually by + name. Defining a pin controller, function and group thus uniquely identify + the set of pins to be used by a certain device. (If only one possible group + of pins is available for the function, no group name need to be supplied - + the core will simply select the first and only group available.) + + In the example case we can define that this particular machine shall + use device spi0 with pinmux function fspi0 group gspi0 and i2c0 on function + fi2c0 group gi2c0, on the primary pin controller, we get mappings + like these: + + { + {"map-spi0", spi0, pinctrl0, fspi0, gspi0}, + {"map-i2c0", i2c0, pinctrl0, fi2c0, gi2c0} + } + + Every map must be assigned a symbolic name, pin controller and function. + The group is not compulsory - if it is omitted the first group presented by + the driver as applicable for the function will be selected, which is + useful for simple cases. + + The device name is present in map entries tied to specific devices. Maps + without device names are referred to as SYSTEM pinmuxes, such as can be taken + by the machine implementation on boot and not tied to any specific device. + + It is possible to map several groups to the same combination of device, + pin controller and function. This is for cases where a certain function on + a certain pin controller may use different sets of pins in different + configurations. + +- PINS for a certain FUNCTION using a certain PIN GROUP on a certain + PIN CONTROLLER are provided on a first-come first-serve basis, so if some + other device mux setting or GPIO pin request has already taken your physical + pin, you will be denied the use of it. To get (activate) a new setting, the + old one has to be put (deactivated) first. + +Sometimes the documentation and hardware registers will be oriented around +pads (or "fingers") rather than pins - these are the soldering surfaces on the +silicon inside the package, and may or may not match the actual number of +pins/balls underneath the capsule. Pick some enumeration that makes sense to +you. Define enumerators only for the pins you can control if that makes sense. + +Assumptions: + +We assume that the number possible function maps to pin groups is limited by +the hardware. I.e. we assume that there is no system where any function can be +mapped to any pin, like in a phone exchange. So the available pins groups for +a certain function will be limited to a few choices (say up to eight or so), +not hundreds or any amount of choices. This is the characteristic we have found +by inspecting available pinmux hardware, and a necessary assumption since we +expect pinmux drivers to present *all* possible function vs pin group mappings +to the subsystem. + + +Pinmux drivers +============== + +The pinmux core takes care of preventing conflicts on pins and calling +the pin controller driver to execute different settings. + +It is the responsibility of the pinmux driver to impose further restrictions +(say for example infer electronic limitations due to load etc) to determine +whether or not the requested function can actually be allowed, and in case it +is possible to perform the requested mux setting, poke the hardware so that +this happens. + +Pinmux drivers are required to supply a few callback functions, some are +optional. Usually the enable() and disable() functions are implemented, +writing values into some certain registers to activate a certain mux setting +for a certain pin. + +A simple driver for the above example will work by setting bits 0, 1, 2, 3 or 4 +into some register named MUX to select a certain function with a certain +group of pins would work something like this: + +#include +#include + +struct foo_group { + const char *name; + const unsigned int *pins; + const unsigned num_pins; +}; + +static const unsigned spi0_0_pins[] = { 0, 8, 16, 24 }; +static const unsigned spi0_1_pins[] = { 38, 46, 54, 62 }; +static const unsigned i2c0_pins[] = { 24, 25 }; +static const unsigned mmc0_1_pins[] = { 56, 57 }; +static const unsigned mmc0_2_pins[] = { 58, 59 }; +static const unsigned mmc0_3_pins[] = { 60, 61, 62, 63 }; + +static const struct foo_group foo_groups[] = { + { + .name = "spi0_0_grp", + .pins = spi0_0_pins, + .num_pins = ARRAY_SIZE(spi0_0_pins), + }, + { + .name = "spi0_1_grp", + .pins = spi0_1_pins, + .num_pins = ARRAY_SIZE(spi0_1_pins), + }, + { + .name = "i2c0_grp", + .pins = i2c0_pins, + .num_pins = ARRAY_SIZE(i2c0_pins), + }, + { + .name = "mmc0_1_grp", + .pins = mmc0_1_pins, + .num_pins = ARRAY_SIZE(mmc0_1_pins), + }, + { + .name = "mmc0_2_grp", + .pins = mmc0_2_pins, + .num_pins = ARRAY_SIZE(mmc0_2_pins), + }, + { + .name = "mmc0_3_grp", + .pins = mmc0_3_pins, + .num_pins = ARRAY_SIZE(mmc0_3_pins), + }, +}; + + +static int foo_list_groups(struct pinctrl_dev *pctldev, unsigned selector) +{ + if (selector >= ARRAY_SIZE(foo_groups)) + return -EINVAL; + return 0; +} + +static const char *foo_get_group_name(struct pinctrl_dev *pctldev, + unsigned selector) +{ + return foo_groups[selector].name; +} + +static int foo_get_group_pins(struct pinctrl_dev *pctldev, unsigned selector, + unsigned ** const pins, + unsigned * const num_pins) +{ + *pins = (unsigned *) foo_groups[selector].pins; + *num_pins = foo_groups[selector].num_pins; + return 0; +} + +static struct pinctrl_ops foo_pctrl_ops = { + .list_groups = foo_list_groups, + .get_group_name = foo_get_group_name, + .get_group_pins = foo_get_group_pins, +}; + +struct foo_pmx_func { + const char *name; + const char * const *groups; + const unsigned num_groups; +}; + +static const char * const spi0_groups[] = { "spi0_1_grp" }; +static const char * const i2c0_groups[] = { "i2c0_grp" }; +static const char * const mmc0_groups[] = { "mmc0_1_grp", "mmc0_2_grp", + "mmc0_3_grp" }; + +static const struct foo_pmx_func foo_functions[] = { + { + .name = "spi0", + .groups = spi0_groups, + .num_groups = ARRAY_SIZE(spi0_groups), + }, + { + .name = "i2c0", + .groups = i2c0_groups, + .num_groups = ARRAY_SIZE(i2c0_groups), + }, + { + .name = "mmc0", + .groups = mmc0_groups, + .num_groups = ARRAY_SIZE(mmc0_groups), + }, +}; + +int foo_list_funcs(struct pinctrl_dev *pctldev, unsigned selector) +{ + if (selector >= ARRAY_SIZE(foo_functions)) + return -EINVAL; + return 0; +} + +const char *foo_get_fname(struct pinctrl_dev *pctldev, unsigned selector) +{ + return myfuncs[selector].name; +} + +static int foo_get_groups(struct pinctrl_dev *pctldev, unsigned selector, + const char * const **groups, + unsigned * const num_groups) +{ + *groups = foo_functions[selector].groups; + *num_groups = foo_functions[selector].num_groups; + return 0; +} + +int foo_enable(struct pinctrl_dev *pctldev, unsigned selector, + unsigned group) +{ + u8 regbit = (1 << group); + + writeb((readb(MUX)|regbit), MUX) + return 0; +} + +int foo_disable(struct pinctrl_dev *pctldev, unsigned selector, + unsigned group) +{ + u8 regbit = (1 << group); + + writeb((readb(MUX) & ~(regbit)), MUX) + return 0; +} + +struct pinmux_ops foo_pmxops = { + .list_functions = foo_list_funcs, + .get_function_name = foo_get_fname, + .get_function_groups = foo_get_groups, + .enable = foo_enable, + .disable = foo_disable, +}; + +/* Pinmux operations are handled by some pin controller */ +static struct pinctrl_desc foo_desc = { + ... + .pctlops = &foo_pctrl_ops, + .pmxops = &foo_pmxops, +}; + +In the example activating muxing 0 and 1 at the same time setting bits +0 and 1, uses one pin in common so they would collide. + +The beauty of the pinmux subsystem is that since it keeps track of all +pins and who is using them, it will already have denied an impossible +request like that, so the driver does not need to worry about such +things - when it gets a selector passed in, the pinmux subsystem makes +sure no other device or GPIO assignment is already using the selected +pins. Thus bits 0 and 1 in the control register will never be set at the +same time. + +All the above functions are mandatory to implement for a pinmux driver. + + +Pinmux interaction with the GPIO subsystem +========================================== + +The function list could become long, especially if you can convert every +individual pin into a GPIO pin independent of any other pins, and then try +the approach to define every pin as a function. + +In this case, the function array would become 64 entries for each GPIO +setting and then the device functions. + +For this reason there is an additional function a pinmux driver can implement +to enable only GPIO on an individual pin: .gpio_request_enable(). The same +.free() function as for other functions is assumed to be usable also for +GPIO pins. + +This function will pass in the affected GPIO range identified by the pin +controller core, so you know which GPIO pins are being affected by the request +operation. + +Alternatively it is fully allowed to use named functions for each GPIO +pin, the pinmux_request_gpio() will attempt to obtain the function "gpioN" +where "N" is the global GPIO pin number if no special GPIO-handler is +registered. + + +Pinmux board/machine configuration +================================== + +Boards and machines define how a certain complete running system is put +together, including how GPIOs and devices are muxed, how regulators are +constrained and how the clock tree looks. Of course pinmux settings are also +part of this. + +A pinmux config for a machine looks pretty much like a simple regulator +configuration, so for the example array above we want to enable i2c and +spi on the second function mapping: + +#include + +static struct pinmux_map pmx_mapping[] = { + { + .ctrl_dev_name = "pinctrl.0", + .function = "spi0", + .dev_name = "foo-spi.0", + }, + { + .ctrl_dev_name = "pinctrl.0", + .function = "i2c0", + .dev_name = "foo-i2c.0", + }, + { + .ctrl_dev_name = "pinctrl.0", + .function = "mmc0", + .dev_name = "foo-mmc.0", + }, +}; + +The dev_name here matches to the unique device name that can be used to look +up the device struct (just like with clockdev or regulators). The function name +must match a function provided by the pinmux driver handling this pin range. + +As you can see we may have several pin controllers on the system and thus +we need to specify which one of them that contain the functions we wish +to map. The map can also use struct device * directly, so there is no +inherent need to use strings to specify .dev_name or .ctrl_dev_name, these +are for the situation where you do not have a handle to the struct device *, +for example if they are not yet instantiated or cumbersome to obtain. + +You register this pinmux mapping to the pinmux subsystem by simply: + + ret = pinmux_register_mappings(&pmx_mapping, ARRAY_SIZE(pmx_mapping)); + +Since the above construct is pretty common there is a helper macro to make +it even more compact which assumes you want to use pinctrl.0 and position +0 for mapping, for example: + +static struct pinmux_map pmx_mapping[] = { + PINMUX_MAP_PRIMARY("I2CMAP", "i2c0", "foo-i2c.0"), +}; + + +Complex mappings +================ + +As it is possible to map a function to different groups of pins an optional +.group can be specified like this: + +... +{ + .name = "spi0-pos-A", + .ctrl_dev_name = "pinctrl.0", + .function = "spi0", + .group = "spi0_0_grp", + .dev_name = "foo-spi.0", +}, +{ + .name = "spi0-pos-B", + .ctrl_dev_name = "pinctrl.0", + .function = "spi0", + .group = "spi0_1_grp", + .dev_name = "foo-spi.0", +}, +... + +This example mapping is used to switch between two positions for spi0 at +runtime, as described further below under the heading "Runtime pinmuxing". + +Further it is possible to match several groups of pins to the same function +for a single device, say for example in the mmc0 example above, where you can +additively expand the mmc0 bus from 2 to 4 to 8 pins. If we want to use all +three groups for a total of 2+2+4 = 8 pins (for an 8-bit MMC bus as is the +case), we define a mapping like this: + +... +{ + .name "2bit" + .ctrl_dev_name = "pinctrl.0", + .function = "mmc0", + .group = "mmc0_0_grp", + .dev_name = "foo-mmc.0", +}, +{ + .name "4bit" + .ctrl_dev_name = "pinctrl.0", + .function = "mmc0", + .group = "mmc0_0_grp", + .dev_name = "foo-mmc.0", +}, +{ + .name "4bit" + .ctrl_dev_name = "pinctrl.0", + .function = "mmc0", + .group = "mmc0_1_grp", + .dev_name = "foo-mmc.0", +}, +{ + .name "8bit" + .ctrl_dev_name = "pinctrl.0", + .function = "mmc0", + .group = "mmc0_0_grp", + .dev_name = "foo-mmc.0", +}, +{ + .name "8bit" + .ctrl_dev_name = "pinctrl.0", + .function = "mmc0", + .group = "mmc0_1_grp", + .dev_name = "foo-mmc.0", +}, +{ + .name "8bit" + .ctrl_dev_name = "pinctrl.0", + .function = "mmc0", + .group = "mmc0_2_grp", + .dev_name = "foo-mmc.0", +}, +... + +The result of grabbing this mapping from the device with something like +this (see next paragraph): + + pmx = pinmux_get(&device, "8bit"); + +Will be that you activate all the three bottom records in the mapping at +once. Since they share the same name, pin controller device, funcion and +device, and since we allow multiple groups to match to a single device, they +all get selected, and they all get enabled and disable simultaneously by the +pinmux core. + + +Pinmux requests from drivers +============================ + +Generally it is discouraged to let individual drivers get and enable pinmuxes. +So if possible, handle the pinmuxes in platform code or some other place where +you have access to all the affected struct device * pointers. In some cases +where a driver needs to switch between different mux mappings at runtime +this is not possible. + +A driver may request a certain mux to be activated, usually just the default +mux like this: + +#include + +struct foo_state { + struct pinmux *pmx; + ... +}; + +foo_probe() +{ + /* Allocate a state holder named "state" etc */ + struct pinmux pmx; + + pmx = pinmux_get(&device, NULL); + if IS_ERR(pmx) + return PTR_ERR(pmx); + pinmux_enable(pmx); + + state->pmx = pmx; +} + +foo_remove() +{ + pinmux_disable(state->pmx); + pinmux_put(state->pmx); +} + +If you want to grab a specific mux mapping and not just the first one found for +this device you can specify a specific mapping name, for example in the above +example the second i2c0 setting: pinmux_get(&device, "spi0-pos-B"); + +This get/enable/disable/put sequence can just as well be handled by bus drivers +if you don't want each and every driver to handle it and you know the +arrangement on your bus. + +The semantics of the get/enable respective disable/put is as follows: + +- pinmux_get() is called in process context to reserve the pins affected with + a certain mapping and set up the pinmux core and the driver. It will allocate + a struct from the kernel memory to hold the pinmux state. + +- pinmux_enable()/pinmux_disable() is quick and can be called from fastpath + (irq context) when you quickly want to set up/tear down the hardware muxing + when running a device driver. Usually it will just poke some values into a + register. + +- pinmux_disable() is called in process context to tear down the pin requests + and release the state holder struct for the mux setting. + +Usually the pinmux core handled the get/put pair and call out to the device +drivers bookkeeping operations, like checking available functions and the +associated pins, whereas the enable/disable pass on to the pin controller +driver which takes care of activating and/or deactivating the mux setting by +quickly poking some registers. + +The pins are allocated for your device when you issue the pinmux_get() call, +after this you should be able to see this in the debugfs listing of all pins. + + +System pinmux hogging +===================== + +A system pinmux map entry, i.e. a pinmux setting that does not have a device +associated with it, can be hogged by the core when the pin controller is +registered. This means that the core will attempt to call pinmux_get() and +pinmux_enable() on it immediately after the pin control device has been +registered. + +This is enabled by simply setting the .hog_on_boot field in the map to true, +like this: + +{ + .name "POWERMAP" + .ctrl_dev_name = "pinctrl.0", + .function = "power_func", + .hog_on_boot = true, +}, + +Since it may be common to request the core to hog a few always-applicable +mux settings on the primary pin controller, there is a convenience macro for +this: + +PINMUX_MAP_PRIMARY_SYS_HOG("POWERMAP", "power_func") + +This gives the exact same result as the above construction. + + +Runtime pinmuxing +================= + +It is possible to mux a certain function in and out at runtime, say to move +an SPI port from one set of pins to another set of pins. Say for example for +spi0 in the example above, we expose two different groups of pins for the same +function, but with different named in the mapping as described under +"Advanced mapping" above. So we have two mappings named "spi0-pos-A" and +"spi0-pos-B". + +This snippet first muxes the function in the pins defined by group A, enables +it, disables and releases it, and muxes it in on the pins defined by group B: + +foo_switch() +{ + struct pinmux pmx; + + /* Enable on position A */ + pmx = pinmux_get(&device, "spi0-pos-A"); + if IS_ERR(pmx) + return PTR_ERR(pmx); + pinmux_enable(pmx); + + /* This releases the pins again */ + pinmux_disable(pmx); + pinmux_put(pmx); + + /* Enable on position B */ + pmx = pinmux_get(&device, "spi0-pos-B"); + if IS_ERR(pmx) + return PTR_ERR(pmx); + pinmux_enable(pmx); + ... +} + +The above has to be done from process context. diff --git a/MAINTAINERS b/MAINTAINERS index ae8820e173a2..e113be50cc08 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -5010,6 +5010,11 @@ L: linux-mtd@lists.infradead.org S: Maintained F: drivers/mtd/devices/phram.c +PIN CONTROL SUBSYSTEM +M: Linus Walleij +S: Maintained +F: drivers/pinmux/ + PKTCDVD DRIVER M: Peter Osterlund S: Maintained diff --git a/drivers/Kconfig b/drivers/Kconfig index 95b9e7eefadc..e73aaaee0138 100644 --- a/drivers/Kconfig +++ b/drivers/Kconfig @@ -56,6 +56,8 @@ source "drivers/pps/Kconfig" source "drivers/ptp/Kconfig" +source "drivers/pinctrl/Kconfig" + source "drivers/gpio/Kconfig" source "drivers/w1/Kconfig" diff --git a/drivers/Makefile b/drivers/Makefile index 7fa433a7030c..e7afb3acbc67 100644 --- a/drivers/Makefile +++ b/drivers/Makefile @@ -5,6 +5,8 @@ # Rewritten to use lists instead of if-statements. # +# GPIO must come after pinctrl as gpios may need to mux pins etc +obj-y += pinctrl/ obj-y += gpio/ obj-$(CONFIG_PCI) += pci/ obj-$(CONFIG_PARISC) += parisc/ diff --git a/drivers/pinctrl/Kconfig b/drivers/pinctrl/Kconfig new file mode 100644 index 000000000000..02b4d4e92ffe --- /dev/null +++ b/drivers/pinctrl/Kconfig @@ -0,0 +1,29 @@ +# +# PINCTRL infrastructure and drivers +# + +menuconfig PINCTRL + bool "PINCTRL Support" + depends on EXPERIMENTAL + help + This enables the PINCTRL subsystem for controlling pins + on chip packages, for example multiplexing pins on primarily + PGA and BGA packages for systems on chip. + + If unsure, say N. + +if PINCTRL + +config PINMUX + bool "Support pinmux controllers" + help + Say Y here if you want the pincontrol subsystem to handle pin + multiplexing drivers. + +config DEBUG_PINCTRL + bool "Debug PINCTRL calls" + depends on DEBUG_KERNEL + help + Say Y here to add some extra checks and diagnostics to PINCTRL calls. + +endif diff --git a/drivers/pinctrl/Makefile b/drivers/pinctrl/Makefile new file mode 100644 index 000000000000..596ce9f22896 --- /dev/null +++ b/drivers/pinctrl/Makefile @@ -0,0 +1,6 @@ +# generic pinmux support + +ccflags-$(CONFIG_DEBUG_PINMUX) += -DDEBUG + +obj-$(CONFIG_PINCTRL) += core.o +obj-$(CONFIG_PINMUX) += pinmux.o diff --git a/drivers/pinctrl/core.c b/drivers/pinctrl/core.c new file mode 100644 index 000000000000..b2eaf8d4412a --- /dev/null +++ b/drivers/pinctrl/core.c @@ -0,0 +1,599 @@ +/* + * Core driver for the pin control subsystem + * + * Copyright (C) 2011 ST-Ericsson SA + * Written on behalf of Linaro for ST-Ericsson + * Based on bits of regulator core, gpio core and clk core + * + * Author: Linus Walleij + * + * License terms: GNU General Public License (GPL) version 2 + */ +#define pr_fmt(fmt) "pinctrl core: " fmt + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include "core.h" +#include "pinmux.h" + +/* Global list of pin control devices */ +static DEFINE_MUTEX(pinctrldev_list_mutex);

This property specifies the PCI address of MSIIR (message signaled interrupt index register). In commit 3da34aae ("powerpc/fsl: Support unique MSI addresses per PCIe Root Complex"), the msi_addr_hi/msi_addr_lo fields of struct fsl_msi were redefined from an actual address to just an offset, but the fields were not renamed accordingly. These fields are replace with a single field, msiir_offset, to reflect the new meaning.

The +Freescale MSI driver calculates the address of MSIIR (in the MSI register +block) and sets that address as the MSI message address. + +In a virtualized environment, the hypervisor may need to create an IOMMU +mapping for MSIIR. The Freescale ePAPR hypervisor has this requirement +because of hardware limitations of the Peripheral Access Management Unit +(PAMU), which is currently the only IOMMU that the hypervisor supports. +The ATMU is programmed with the guest physical address, and the PAMU +intercepts transactions and reroutes them to the true physical address. + +In the PAMU, each PCI controller is given only one primary window. The +PAMU restricts DMA operations so that they can only occur within a window. +Because PCI devices must be able to DMA to memory, the primary window must +be used to cover all of the guest's memory space. + +PAMU primary windows can be divided into 256 subwindows, and each +subwindow can have its own address mapping ("guest physical" to "true +physical"). However, each subwindow has to have the same alignment, which +means they cannot be located at just any address. Because of these +restrictions, it is usually impossible to create a 4KB subwindow that +covers MSIIR where it's normally located. + +Therefore, the hypervisor has to create a subwindow inside the same +primary window used for memory, but mapped to the MSIR block (where MSIIR +lives). The first subwindow after the end of guest memory is used for +this. The address specified in the msi-address-64 property is the PCI +address of MSIIR. The hypervisor configures the PAMU to map that address to +the true physical address of MSIIR. diff --git a/arch/powerpc/sysdev/fsl_msi.c b/arch/powerpc/sysdev/fsl_msi.c index 1cca25146b1f..e5c344d336ea 100644 --- a/arch/powerpc/sysdev/fsl_msi.c +++ b/arch/powerpc/sysdev/fsl_msi.c @@ -30,7 +30,7 @@ LIST_HEAD(msi_head); struct fsl_msi_feature { u32 fsl_pic_ip; - u32 msiir_offset; + u32 msiir_offset; /* Offset of MSIIR, relative to start of MSIR bank */ }; struct fsl_msi_cascade_data { @@ -126,10 +126,19 @@ static void fsl_compose_msi_msg(struct pci_dev *pdev, int hwirq, { struct fsl_msi *msi_data = fsl_msi_data; struct pci_controller *hose = pci_bus_to_host(pdev->bus); - u64 base = fsl_pci_immrbar_base(hose); + u64 address; /* Physical address of the MSIIR */ + int len; + const u64 *reg; + + /* If the msi-address-64 property exists, then use it */ + reg = of_get_property(hose->dn, "msi-address-64", &len); + if (reg && (len == sizeof(u64))) + address = be64_to_cpup(reg); + else + address = fsl_pci_immrbar_base(hose) + msi_data->msiir_offset; - msg->address_lo = msi_data->msi_addr_lo + lower_32_bits(base); - msg->address_hi = msi_data->msi_addr_hi + upper_32_bits(base); + msg->address_lo = lower_32_bits(address); + msg->address_hi = upper_32_bits(address); msg->data = hwirq; @@ -359,8 +368,7 @@ static int __devinit fsl_of_msi_probe(struct platform_device *dev) msi->irqhost->host_data = msi; - msi->msi_addr_hi = 0x0; - msi->msi_addr_lo = features->msiir_offset + (res.start & 0xfffff); + msi->msiir_offset = features->msiir_offset + (res.start & 0xfffff); rc = fsl_msi_init_allocator(msi); if (rc) { diff --git a/arch/powerpc/sysdev/fsl_msi.h b/arch/powerpc/sysdev/fsl_msi.h index 624580c252d7..1313abbc5200 100644 --- a/arch/powerpc/sysdev/fsl_msi.h +++ b/arch/powerpc/sysdev/fsl_msi.h @@ -28,8 +28,7 @@ struct fsl_msi { unsigned long cascade_irq; - u32 msi_addr_lo; - u32 msi_addr_hi; + u32 msiir_offset; /* Offset of MSIIR, relative to start of CCSR */ void __iomem *msi_regs; u32 feature; int msi_virqs[NR_MSI_REG]; -- cgit v1.2.3 From 873c07da6abd5519a7850caa90f226d3b15e3fba Mon Sep 17 00:00:00 2001 From: Renzo Dani Date: Sun, 9 Oct 2011 06:43:50 -0300 Subject: [media] update az6027 firmware URL Signed-off-by: Renzo Dani Signed-off-by: Mauro Carvalho Chehab --- Documentation/dvb/get_dvb_firmware | 13 ++----------- 1 file changed, 2 insertions(+), 11 deletions(-) (limited to 'Documentation') diff --git a/Documentation/dvb/get_dvb_firmware b/Documentation/dvb/get_dvb_firmware index 996f5786099f..e67be7afc78b 100755 --- a/Documentation/dvb/get_dvb_firmware +++ b/Documentation/dvb/get_dvb_firmware @@ -576,19 +576,10 @@ sub ngene { } sub az6027{ - my $file = "AZ6027_Linux_Driver.tar.gz"; - my $url = "http://linux.terratec.de/files/$file"; my $firmware = "dvb-usb-az6027-03.fw"; + my $url = "http://linux.terratec.de/files/TERRATEC_S7/$firmware"; - wgetfile($file, $url); - - #untar - if( system("tar xzvf $file $firmware")){ - die "failed to untar firmware"; - } - if( system("rm $file")){ - die ("unable to remove unnecessary files"); - } + wgetfile($firmware, $url); $firmware; } -- cgit v1.2.3 From aecc3130da7d3a02439bcba428e9fe470ec11f6f Mon Sep 17 00:00:00 2001 From: Vikas Chaudhary Date: Fri, 7 Oct 2011 16:55:40 -0700 Subject: [SCSI] qla4xxx: Update license Signed-off-by: Vikas Chaudhary Reviewed-by: Mike Christie Signed-off-by: James Bottomley --- Documentation/scsi/00-INDEX | 2 + Documentation/scsi/LICENSE.qla4xxx | 310 +++++++++++++++++++++++++++++++++++++ 2 files changed, 312 insertions(+) create mode 100644 Documentation/scsi/LICENSE.qla4xxx (limited to 'Documentation') diff --git a/Documentation/scsi/00-INDEX b/Documentation/scsi/00-INDEX index c2e18e109858..b48ded55b555 100644 --- a/Documentation/scsi/00-INDEX +++ b/Documentation/scsi/00-INDEX @@ -28,6 +28,8 @@ LICENSE.FlashPoint - Licence of the Flashpoint driver LICENSE.qla2xxx - License for QLogic Linux Fibre Channel HBA Driver firmware. +LICENSE.qla4xxx + - License for QLogic Linux iSCSI HBA Driver.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6.

We can check it through 'suspend_stats' entry in debugfs. The motivation of the patch: We are enabling power features on Medfield. Comparing with PC/notebook, a mobile enters/exits suspend-2-ram (we call it s3 on Medfield) far more frequently. If it can't enter suspend-2-ram in time, the power might be used up soon. We often find sometimes, a device suspend fails. Then, system retries s3 over and over again. As display is off, testers and developers don't know what happens. Some testers and developers complain they don't know if system tries suspend-2-ram, and what device fails to suspend. They need such info for a quick check. The patch adds suspend_stats under debugfs for users to check suspend to RAM statistics quickly. If not using this patch, we have other methods to get info about what device fails. One is to turn on CONFIG_PM_DEBUG, but users would get too much info and testers need recompile the system. In addition, dynamic debug is another good tool to dump debug info. But it still doesn't match our utilization scenario closely. 1) user need write a user space parser to process the syslog output; 2) Our testing scenario is we leave the mobile for at least hours. Then, check its status. No serial console available during the testing. One is because console would be suspended, and the other is serial console connecting with spi or HSU devices would consume power. These devices are powered off at suspend-2-ram.

Wysocki" Date: Mon, 26 Sep 2011 20:32:27 +0200 Subject: PM / Hibernate: Freeze kernel threads after preallocating memory There is a problem with the current ordering of hibernate code which leads to deadlocks in some filesystems' memory shrinkers. Namely, some filesystems use freezable kernel threads that are inactive when the hibernate memory preallocation is carried out. Those same filesystems use memory shrinkers that may be triggered by the hibernate memory preallocation. If those memory shrinkers wait for the frozen kernel threads, the hibernate process deadlocks (this happens with XFS, for one example). Apparently, it is not technically viable to redesign the filesystems in question to avoid the situation described above, so the only possible solution of this issue is to defer the freezing of kernel threads until the hibernate memory preallocation is done, which is implemented by this change. Unfortunately, this requires the memory preallocation to be done before the "prepare" stage of device freeze, so after this change the only way drivers can allocate additional memory for their freeze routines in a clean way is to use PM notifiers.

For example, drivers/mmc/host/sdhci.c launches a 200ms delayed work to detect MMC partitions then add disk. We have wait_for_device_probe() and scsi_complete_async_scans() before calling swsusp_check(), but it is not enough to wait for MMC. This patch adds resumewait kernel param just like rootwait so that we have enough time to wait until MMC is ready. The difference is that we wait for resume partition whereas rootwait waits for rootfs partition (which may be on a different device). This patch will make hibernation support many embedded products without SCSI devices, but with devices like MMC.

Numerous platforms like embedded PPC, ARM, and X86 have support for systems with larger physical address than logical. Since 'addr' may contain a physical, logical, or virtual address the easiest solution is to just change the type to 'phys_addr_t' which should always be greater than or equal to the sizeof(void *) such that it can properly hold any of the address types. For physical address we can support up to a 44-bit physical address on a typical 32-bit system as we utilize remap_pfn_range() for the mapping of the memory region and pfn's are represnted by shifting the address by the page size (typically 4k).

What are the issues involved in CPU hotplug? + ------------------------------------------- + +There are some interesting situations involving CPU hotplug and microcode +update on the CPUs, as discussed below: + +[Please bear in mind that the kernel requests the microcode images from +userspace, using the request_firmware() function defined in +drivers/base/firmware_class.c] + + +a. When all the CPUs are identical: + + This is the most common situation and it is quite straightforward: we want + to apply the same microcode revision to each of the CPUs. + To give an example of x86, the collect_cpu_info() function defined in + arch/x86/kernel/microcode_core.c helps in discovering the type of the CPU + and thereby in applying the correct microcode revision to it. + But note that the kernel does not maintain a common microcode image for the + all CPUs, in order to handle case 'b' described below. + + +b. When some of the CPUs are different than the rest: + + In this case since we probably need to apply different microcode revisions + to different CPUs, the kernel maintains a copy of the correct microcode + image for each CPU (after appropriate CPU type/model discovery using + functions such as collect_cpu_info()). + + +c. When a CPU is physically hot-unplugged and a new (and possibly different + type of) CPU is hot-plugged into the system: + + In the current design of the kernel, whenever a CPU is taken offline during + a regular CPU hotplug operation, upon receiving the CPU_DEAD notification + (which is sent by the CPU hotplug code), the microcode update driver's + callback for that event reacts by freeing the kernel's copy of the + microcode image for that CPU. + + Hence, when a new CPU is brought online, since the kernel finds that it + doesn't have the microcode image, it does the CPU type/model discovery + afresh and then requests the userspace for the appropriate microcode image + for that CPU, which is subsequently applied. + + For example, in x86, the mc_cpu_callback() function (which is the microcode + update driver's callback registered for CPU hotplug events) calls + microcode_update_cpu() which would call microcode_init_cpu() in this case, + instead of microcode_resume_cpu() when it finds that the kernel doesn't + have a valid microcode image. This ensures that the CPU type/model + discovery is performed and the right microcode is applied to the CPU after + getting it from userspace. + + +d. Handling microcode update during suspend/hibernate: + + Strictly speaking, during a CPU hotplug operation which does not involve + physically removing or inserting CPUs, the CPUs are not actually powered + off during a CPU offline. They are just put to the lowest C-states possible. + Hence, in such a case, it is not really necessary to re-apply microcode + when the CPUs are brought back online, since they wouldn't have lost the + image during the CPU offline operation. + + This is the usual scenario encountered during a resume after a suspend. + However, in the case of hibernation, since all the CPUs are completely + powered off, during restore it becomes necessary to apply the microcode + images to all the CPUs. + + [Note that we don't expect someone to physically pull out nodes and insert + nodes with a different type of CPUs in-between a suspend-resume or a + hibernate/restore cycle.] + + In the current design of the kernel however, during a CPU offline operation + as part of the suspend/hibernate cycle (the CPU_DEAD_FROZEN notification), + the existing copy of microcode image in the kernel is not freed up. + And during the CPU online operations (during resume/restore), since the + kernel finds that it already has copies of the microcode images for all the + CPUs, it just applies them to the CPUs, avoiding any re-discovery of CPU + type/model and the need for validating whether the microcode revisions are + right for the CPUs or not (due to the above assumption that physical CPU + hotplug will not be done in-between suspend/resume or hibernate/restore + cycles). + + +III. Are there any known problems when regular CPU hotplug and suspend race + with each other? + +Yes, they are listed below: + +1. When invoking regular CPU hotplug, the 'tasks_frozen' argument passed to + the _cpu_down() and _cpu_up() functions is *always* 0. + This might not reflect the true current state of the system, since the + tasks could have been frozen by an out-of-band event such as a suspend + operation in progress. Hence, it will lead to wrong notifications being + sent during the cpu online/offline events (eg, CPU_ONLINE notification + instead of CPU_ONLINE_FROZEN) which in turn will lead to execution of + inappropriate code by the callbacks registered for such CPU hotplug events. + +2. If a regular CPU hotplug stress test happens to race with the freezer due + to a suspend operation in progress at the same time, then we could hit the + situation described below: + + * A regular cpu online operation continues its journey from userspace + into the kernel, since the freezing has not yet begun. + * Then freezer gets to work and freezes userspace. + * If cpu online has not yet completed the microcode update stuff by now, + it will now start waiting on the frozen userspace in the + TASK_UNINTERRUPTIBLE state, in order to get the microcode image. + * Now the freezer continues and tries to freeze the remaining tasks. But + due to this wait mentioned above, the freezer won't be able to freeze + the cpu online hotplug task and hence freezing of tasks fails. + + As a result of this task freezing failure, the suspend operation gets + aborted. -- cgit v1.2.3 From 773e3206e6a8b4c81826dc76057a96ba3cc96672 Mon Sep 17 00:00:00 2001 From: Ike Panhc Date: Tue, 6 Sep 2011 02:32:52 +0800 Subject: ideapad: add debugfs support Add two nodes in debugfs which shows cfg value and its meaning, and status info read from VPC2004.

The +protocol is implemented over the industry-standard SMBus serial interface and +enables programming, control, and real-time monitoring of compliant power +conversion products. This flexible and highly versatile standard allows for +communication between devices based on both analog and digital technologies, and +provides true interoperability which will reduce design complexity and shorten +time to market for power system designers. Pioneered by leading power supply and +semiconductor companies, this open power system standard is maintained and +promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters +with the objective to provide support to, and facilitate adoption among, users. + +Unfortunately, while PMBus commands are standardized, there are no mandatory +commands, and manufacturers can add as many non-standard commands as they like. +Also, different PMBUs devices act differently if non-supported commands are +executed. Some devices return an error, some devices return 0xff or 0xffff and +set a status error flag, and some devices may simply hang up. + +Despite all those difficulties, a generic PMBus device driver is still useful +and supported since kernel version 2.6.39. However, it was necessary to support +device specific extensions in addition to the core PMBus driver, since it is +simply unknown what new device specific functionality PMBus device developers +come up with next. + +To make device specific extensions as scalable as possible, and to avoid having +to modify the core PMBus driver repeatedly for new devices, the PMBus driver was +split into core, generic, and device specific code. The core code (in +pmbus_core.c) provides generic functionality. The generic code (in pmbus.c) +provides support for generic PMBus devices. Device specific code is responsible +for device specific initialization and, if needed, maps device specific +functionality into generic functionality. This is to some degree comparable +to PCI code, where generic code is augmented as needed with quirks for all kinds +of devices. + +PMBus device capabilities auto-detection +======================================== + +For generic PMBus devices, code in pmbus.c attempts to auto-detect all supported +PMBus commands. Auto-detection is somewhat limited, since there are simply too +many variables to consider. For example, it is almost impossible to autodetect +which PMBus commands are paged and which commands are replicated across all +pages (see the PMBus specification for details on multi-page PMBus devices). + +For this reason, it often makes sense to provide a device specific driver if not +all commands can be auto-detected. The data structures in this driver can be +used to inform the core driver about functionality supported by individual +chips. + +Some commands are always auto-detected. This applies to all limit commands +(lcrit, min, max, and crit attributes) as well as associated alarm attributes. +Limits and alarm attributes are auto-detected because there are simply too many +possible combinations to provide a manual configuration interface. + +PMBus internal API +================== + +The API between core and device specific PMBus code is defined in +drivers/hwmon/pmbus/pmbus.h. In addition to the internal API, pmbus.h defines +standard PMBus commands and virtual PMBus commands. + +Standard PMBus commands +----------------------- + +Standard PMBus commands (commands values 0x00 to 0xff) are defined in the PMBUs +specification. + +Virtual PMBus commands +---------------------- + +Virtual PMBus commands are provided to enable support for non-standard +functionality which has been implemented by several chip vendors and is thus +desirable to support. + +Virtual PMBus commands start with command value 0x100 and can thus easily be +distinguished from standard PMBus commands (which can not have values larger +than 0xff). Support for virtual PMBus commands is device specific and thus has +to be implemented in device specific code. + +Virtual commands are named PMBUS_VIRT_xxx and start with PMBUS_VIRT_BASE. All +virtual commands are word sized. + +There are currently two types of virtual commands. + +- READ commands are read-only; writes are either ignored or return an error. +- RESET commands are read/write. Reading reset registers returns zero + (used for detection), writing any value causes the associated history to be + reset. + +Virtual commands have to be handled in device specific driver code. Chip driver +code returns non-negative values if a virtual command is supported, or a +negative error code if not. The chip driver may return -ENODATA or any other +Linux error code in this case, though an error code other than -ENODATA is +handled more efficiently and thus preferred. Either case, the calling PMBus +core code will abort if the chip driver returns an error code when reading +or writing virtual registers (in other words, the PMBus core code will never +send a virtual command to a chip). + +PMBus driver information +------------------------ + +PMBus driver information, defined in struct pmbus_driver_info, is the main means +for device specific drivers to pass information to the core PMBus driver. +Specifically, it provides the following information. + +- For devices supporting its data in Direct Data Format, it provides coefficients + for converting register values into normalized data. This data is usually + provided by chip manufacturers in device datasheets. +- Supported chip functionality can be provided to the core driver. This may be + necessary for chips which react badly if non-supported commands are executed, + and/or to speed up device detection and initialization. +- Several function entry points are provided to support overriding and/or + augmenting generic command execution. This functionality can be used to map + non-standard PMBus commands to standard commands, or to augment standard + command return values with device specific information. + + API functions + ------------- + + Functions provided by chip driver + --------------------------------- + + All functions return the command return value (read) or zero (write) if + successful. A return value of -ENODATA indicates that there is no manufacturer + specific command, but that a standard PMBus command may exist. Any other + negative return value indicates that the commands does not exist for this + chip, and that no attempt should be made to read or write the standard + command. + + As mentioned above, an exception to this rule applies to virtual commands, + which _must_ be handled in driver specific code. See "Virtual PMBus Commands" + above for more details. + + Command execution in the core PMBus driver code is as follows. + + if (chip_access_function) { + status = chip_access_function(); + if (status != -ENODATA) + return status; + } + if (command >= PMBUS_VIRT_BASE) /* For word commands/registers only */ + return -EINVAL; + return generic_access(); + + Chip drivers may provide pointers to the following functions in struct + pmbus_driver_info. All functions are optional. + + int (*read_byte_data)(struct i2c_client *client, int page, int reg); + + Read byte from page , register . + may be -1, which means "current page". + + int (*read_word_data)(struct i2c_client *client, int page, int reg); + + Read word from page , register . + + int (*write_word_data)(struct i2c_client *client, int page, int reg, + u16 word); + + Write word to page , register . + + int (*write_byte)(struct i2c_client *client, int page, u8 value); + + Write byte to page , register . + may be -1, which means "current page". + + int (*identify)(struct i2c_client *client, struct pmbus_driver_info *info); + + Determine supported PMBus functionality. This function is only necessary + if a chip driver supports multiple chips, and the chip functionality is not + pre-determined. It is currently only used by the generic pmbus driver + (pmbus.c). + + Functions exported by core driver + --------------------------------- + + Chip drivers are expected to use the following functions to read or write + PMBus registers. Chip drivers may also use direct I2C commands. If direct I2C + commands are used, the chip driver code must not directly modify the current + page, since the selected page is cached in the core driver and the core driver + will assume that it is selected.

For such chips, checking the status register is mandatory when +trying to determine if a chip register exists or not. +Other PMBus chips don't support the STATUS_CML register, or report +communication errors for no explicable reason. For such chips, checking the +status register must be disabled. + +Some i2c controllers do not support single-byte commands (write commands with +no data, i2c_smbus_write_byte()). With such controllers, clearing the status +register is impossible, and the PMBUS_SKIP_STATUS_CHECK flag must be set. -- cgit v1.2.3 From 200855e52db1b1834121ba57fbd89c5b4911e02c Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Fri, 29 Jul 2011 22:21:53 -0700 Subject: hwmon: (pmbus) Add support for Intersil power management chips Add support for Intersil / Zilker Labs ZL2004, ZL2006, ZL2008, ZL2105, ZL2106, ZL6100, and ZL6105.

In order to reserve memory for the header in the 2nd kernel also the size is required. Current kdump architecture backends use different methods to do that, e.g. x86 uses the memmap= kernel parameter. On s390 there is no easy way to transfer this information. Therefore the elfcorehdr kernel parameter is extended to also pass the size. This now can also be used as standard mechanism by all future kdump architecture backends. The syntax of the kernel parameter is extended as follows: elfcorehdr=[size[KMG]@]offset[KMG] This change is backward compatible because elfcorehdr=size is still allowed.

In late 2010 we were seeing that various +different targets were rolling their own data strutures, for example: + +- Mikulas Patocka's multisnap implementation +- Heinz Mauelshagen's thin provisioning target +- Another btree-based caching target posted to dm-devel +- Another multi-snapshot target based on a design of Daniel Phillips + +Maintaining these data structures takes a lot of work, so if possible +we'd like to reduce the number. + +The persistent-data library is an attempt to provide a re-usable +framework for people who want to store metadata in device-mapper +targets. It's currently used by the thin-provisioning target and an +upcoming hierarchical storage target. + +Overview +======== + +The main documentation is in the header files which can all be found +under drivers/md/persistent-data. + +The block manager +----------------- + +dm-block-manager.[hc] + +This provides access to the data on disk in fixed sized-blocks. There +is a read/write locking interface to prevent concurrent accesses, and +keep data that is being used in the cache. + +Clients of persistent-data are unlikely to use this directly. + +The transaction manager +----------------------- + +dm-transaction-manager.[hc] + +This restricts access to blocks and enforces copy-on-write semantics. +The only way you can get hold of a writable block through the +transaction manager is by shadowing an existing block (ie. doing +copy-on-write) or allocating a fresh one. Shadowing is elided within +the same transaction so performance is reasonable. The commit method +ensures that all data is flushed before it writes the superblock. +On power failure your metadata will be as it was when last committed. + +The Space Maps +-------------- + +dm-space-map.h +dm-space-map-metadata.[hc] +dm-space-map-disk.[hc] + +On-disk data structures that keep track of reference counts of blocks. +Also acts as the allocator of new blocks. Currently two +implementations: a simpler one for managing blocks on a different +device (eg. thinly-provisioned data blocks); and one for managing +the metadata space. The latter is complicated by the need to store +its own data within the space it's managing. + +The data structures +------------------- + +dm-btree.[hc] +dm-btree-remove.c +dm-btree-spine.c +dm-btree-internal.h + +Currently there is only one data structure, a hierarchical btree. +There are plans to add more. For example, something with an +array-like interface would see a lot of use. + +The btree is 'hierarchical' in that you can define it to be composed +of nested btrees, and take multiple keys. For example, the +thin-provisioning target uses a btree with two levels of nesting. +The first maps a device id to a mapping tree, and that in turn maps a +virtual block to a physical block. + +Values stored in the btrees can have arbitrary size. Keys are always +64bits, although nesting allows you to use multiple keys. diff --git a/drivers/md/persistent-data/Kconfig b/drivers/md/persistent-data/Kconfig new file mode 100644 index 000000000000..ceb359050a59 --- /dev/null +++ b/drivers/md/persistent-data/Kconfig @@ -0,0 +1,8 @@ +config DM_PERSISTENT_DATA + tristate + depends on BLK_DEV_DM && EXPERIMENTAL + select LIBCRC32C + select DM_BUFIO + ---help--- + Library providing immutable on-disk data structure support for + device-mapper targets such as the thin provisioning target. diff --git a/drivers/md/persistent-data/Makefile b/drivers/md/persistent-data/Makefile new file mode 100644 index 000000000000..cfa95f662230 --- /dev/null +++ b/drivers/md/persistent-data/Makefile @@ -0,0 +1,11 @@ +obj-$(CONFIG_DM_PERSISTENT_DATA) += dm-persistent-data.o +dm-persistent-data-objs := \ + dm-block-manager.o \ + dm-space-map-checker.o \ + dm-space-map-common.o \ + dm-space-map-disk.o \ + dm-space-map-metadata.o \ + dm-transaction-manager.o \ + dm-btree.o \ + dm-btree-remove.o \ + dm-btree-spine.o diff --git a/drivers/md/persistent-data/dm-block-manager.c b/drivers/md/persistent-data/dm-block-manager.c new file mode 100644 index 000000000000..0317ecdc6e53 --- /dev/null +++ b/drivers/md/persistent-data/dm-block-manager.c @@ -0,0 +1,620 @@ +/* + * Copyright (C) 2011 Red Hat, Inc. + * + * This file is released under the GPL. + */ +#include "dm-block-manager.h" +#include "dm-persistent-data-internal.h" +#include "../dm-bufio.h" + +#include +#include +#include +#include +#include +#include + +#define DM_MSG_PREFIX "block manager" + +/*----------------------------------------------------------------*/ + +/* + * This is a read/write semaphore with a couple of differences. + * + * i) There is a restriction on the number of concurrent read locks that + * may be held at once.

The 'thin' target is used to create instances of the virtual devices that are hosted in the 'thin-pool' target. The thin-pool target provides data sharing among devices. This sharing is made possible using the persistent-data library in the previous patch. The main highlight of this implementation, compared to the previous implementation of snapshots, is that it allows many virtual devices to be stored on the same data volume, simplifying administration and allowing sharing of data between volumes (thus reducing disk usage). Another big feature is support for arbitrary depth of recursive snapshots (snapshots of snapshots of snapshots ...). The previous implementation of snapshots did this by chaining together lookup tables, and so performance was O(depth). This new implementation uses a single data structure so we don't get this degradation with depth.

This simplifies administration and +allows the sharing of data between volumes, thus reducing disk usage. + +Another significant feature is support for an arbitrary depth of +recursive snapshots (snapshots of snapshots of snapshots ...). The +previous implementation of snapshots did this by chaining together +lookup tables, and so performance was O(depth). This new +implementation uses a single data structure to avoid this degradation +with depth. Fragmentation may still be an issue, however, in some +scenarios. + +Metadata is stored on a separate device from data, giving the +administrator some freedom, for example to: + +- Improve metadata resilience by storing metadata on a mirrored volume + but data on a non-mirrored one. + +- Improve performance by storing the metadata on SSD. + +Status +====== + +These targets are very much still in the EXPERIMENTAL state. Please +do not yet rely on them in production. But do experiment and offer us +feedback. Different use cases will have different performance +characteristics, for example due to fragmentation of the data volume. + +If you find this software is not performing as expected please mail +dm-devel@redhat.com with details and we'll try our best to improve +things for you. + +Userspace tools for checking and repairing the metadata are under +development. + +Cookbook +======== + +This section describes some quick recipes for using thin provisioning. +They use the dmsetup program to control the device-mapper driver +directly. End users will be advised to use a higher-level volume +manager such as LVM2 once support has been added. + +Pool device +----------- + +The pool device ties together the metadata volume and the data volume. +It maps I/O linearly to the data volume and updates the metadata via +two mechanisms: + +- Function calls from the thin targets + +- Device-mapper 'messages' from userspace which control the creation of new + virtual devices amongst other things. + +Setting up a fresh pool device +------------------------------ + +Setting up a pool device requires a valid metadata device, and a +data device. If you do not have an existing metadata device you can +make one by zeroing the first 4k to indicate empty metadata. + + dd if=/dev/zero of=$metadata_dev bs=4096 count=1 + +The amount of metadata you need will vary according to how many blocks +are shared between thin devices (i.e. through snapshots). If you have +less sharing than average you'll need a larger-than-average metadata device. + +As a guide, we suggest you calculate the number of bytes to use in the +metadata device as 48 * $data_dev_size / $data_block_size but round it up +to 2MB if the answer is smaller. The largest size supported is 16GB. + +If you're creating large numbers of snapshots which are recording large +amounts of change, you may need find you need to increase this. + +Reloading a pool table +---------------------- + +You may reload a pool's table, indeed this is how the pool is resized +if it runs out of space. (N.B. While specifying a different metadata +device when reloading is not forbidden at the moment, things will go +wrong if it does not route I/O to exactly the same on-disk location as +previously.) + +Using an existing pool device +----------------------------- + + dmsetup create pool \ + --table "0 20971520 thin-pool $metadata_dev $data_dev \ + $data_block_size $low_water_mark" + +$data_block_size gives the smallest unit of disk space that can be +allocated at a time expressed in units of 512-byte sectors. People +primarily interested in thin provisioning may want to use a value such +as 1024 (512KB). People doing lots of snapshotting may want a smaller value +such as 128 (64KB). If you are not zeroing newly-allocated data, +a larger $data_block_size in the region of 256000 (128MB) is suggested. +$data_block_size must be the same for the lifetime of the +metadata device. + +$low_water_mark is expressed in blocks of size $data_block_size. If +free space on the data device drops below this level then a dm event +will be triggered which a userspace daemon should catch allowing it to +extend the pool device. Only one such event will be sent. +Resuming a device with a new table itself triggers an event so the +userspace daemon can use this to detect a situation where a new table +already exceeds the threshold. + +Thin provisioning +----------------- + +i) Creating a new thinly-provisioned volume. + + To create a new thinly- provisioned volume you must send a message to an + active pool device, /dev/mapper/pool in this example. + + dmsetup message /dev/mapper/pool 0 "create_thin 0" + + Here '0' is an identifier for the volume, a 24-bit number. It's up + to the caller to allocate and manage these identifiers. If the + identifier is already in use, the message will fail with -EEXIST. + +ii) Using a thinly-provisioned volume. + + Thinly-provisioned volumes are activated using the 'thin' target: + + dmsetup create thin --table "0 2097152 thin /dev/mapper/pool 0" + + The last parameter is the identifier for the thinp device. + +Internal snapshots +------------------ + +i) Creating an internal snapshot. + + Snapshots are created with another message to the pool. + + N.B. If the origin device that you wish to snapshot is active, you + must suspend it before creating the snapshot to avoid corruption. + This is NOT enforced at the moment, so please be careful! + + dmsetup suspend /dev/mapper/thin + dmsetup message /dev/mapper/pool 0 "create_snap 1 0" + dmsetup resume /dev/mapper/thin + + Here '1' is the identifier for the volume, a 24-bit number. '0' is the + identifier for the origin device. + +ii) Using an internal snapshot. + + Once created, the user doesn't have to worry about any connection + between the origin and the snapshot. Indeed the snapshot is no + different from any other thinly-provisioned device and can be + snapshotted itself via the same method. It's perfectly legal to + have only one of them active, and there's no ordering requirement on + activating or removing them both. (This differs from conventional + device-mapper snapshots.) + + Activate it exactly the same way as any other thinly-provisioned volume: + + dmsetup create snap --table "0 2097152 thin /dev/mapper/pool 1" + +Deactivation +------------ + +All devices using a pool must be deactivated before the pool itself +can be. + + dmsetup remove thin + dmsetup remove snap + dmsetup remove pool + +Reference +========= + +'thin-pool' target +------------------ + +i) Constructor + + thin-pool \ + [ []*] + + Optional feature arguments: + - 'skip_block_zeroing': skips the zeroing of newly-provisioned blocks. + + Data block size must be between 64KB (128 sectors) and 1GB + (2097152 sectors) inclusive. + + +ii) Status + + / + / + + + transaction id: + A 64-bit number used by userspace to help synchronise with metadata + from volume managers. + + used data blocks / total data blocks + If the number of free blocks drops below the pool's low water mark a + dm event will be sent to userspace.

They are just two device trees that happen to point to the + * same data blocks. + * + * When we get a write in we decide if it's to a shared data block using + * some timestamp magic. If it is, we have to break sharing. + * + * Let's say we write to a shared block in what was the origin. The + * steps are: + * + * i) plug io further to this physical block. (see bio_prison code). + * + * ii) quiesce any read io to that shared data block. Obviously + * including all devices that share this block. (see deferred_set code) + * + * iii) copy the data block to a newly allocate block. This step can be + * missed out if the io covers the block. (schedule_copy). + * + * iv) insert the new mapping into the origin's btree + * (process_prepared_mappings). This act of inserting breaks some + * sharing of btree nodes between the two devices. Breaking sharing only + * effects the btree of that specific device. Btrees for the other + * devices that share the block never change. The btree for the origin + * device as it was after the last commit is untouched, ie. we're using + * persistent data structures in the functional programming sense. + * + * v) unplug io to this physical block, including the io that triggered + * the breaking of sharing. + * + * Steps (ii) and (iii) occur in parallel. + * + * The metadata _doesn't_ need to be committed before the io continues. We + * get away with this because the io is always written to a _new_ block. + * If there's a crash, then: + * + * - The origin mapping will point to the old origin block (the shared + * one). This will contain the data as it was before the io that triggered + * the breaking of sharing came in. + * + * - The snap mapping still points to the old block. As it would after + * the commit. + * + * The downside of this scheme is the timestamp magic isn't perfect, and + * will continue to think that data block in the snapshot device is shared + * even after the write to the origin has broken sharing. I suspect data + * blocks will typically be shared by many different devices, so we're + * breaking sharing n + 1 times, rather than n, where n is the number of + * devices that reference this data block.

This should allow environments like qemu to use virtio-based block & network devices even on platforms without PCI support. One can define and register a platform device which resources will describe memory mapped control registers and "mailbox" interrupt. Such device can be also instantiated using the Device Tree node with compatible property equal "virtio,mmio".

Wrap dentry_lru_del() and use the new _prune() helper in the cases where we are about to unhash and kill the dentry. This will be used by Ceph to maintain a flag indicating whether the complete contents of a directory are contained in the dcache, allowing it to satisfy lookups and readdir without addition server communication. Renumber a few DCACHE_* #defines to group DCACHE_OP_PRUNE with the other DCACHE_OP_ bits.

The memcg implementation of comparing those lists instead reports whether the whole memcg is low on the requested type of inactive pages, considering all nodes and zones. This can lead to an oversized active list not being scanned because of the state of the other lists in the memcg, as well as an active list being scanned while its corresponding inactive list has enough pages. Not only is this wrong, it's also a scalability hazard, because the global memory state over all nodes and zones has to be gathered for each memcg and zone scanned. Make these calculations purely based on the size of the two LRU lists that are actually affected by the outcome of the decision.

The idle callback routine could then schedule a delayed suspend for some time later. However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend). No notifications were sent, and there was no clear mechanism to retry failed suspends. This caused problems for the usbhid driver, because it fails autosuspend attempts as long as a key is being held down. Therefore this patch (as1492) adds a mechanism for retrying failed autosuspends. If the callback routine updates the last_busy field so that the next autosuspend expiration time is in the future, the autosuspend will automatically be rescheduled.

Now, as the framework factored out the common +components, those drivers can be lightened making it a user of the framework. +This document shall guide you for this task. The necessary steps are described +as well as things to look out for. + + +Remove the file_operations struct +--------------------------------- + +Old drivers define their own file_operations for actions like open(), write(), +etc... These are now handled by the framework and just call the driver when +needed. So, in general, the 'file_operations' struct and assorted functions can +go. Only very few driver-specific details have to be moved to other functions. +Here is a overview of the functions and probably needed actions: + +- open: Everything dealing with resource management (file-open checks, magic + close preparations) can simply go. Device specific stuff needs to go to the + driver specific start-function. Note that for some drivers, the start-function + also serves as the ping-function. If that is the case and you need start/stop + to be balanced (clocks!), you are better off refactoring a separate start-function. + +- close: Same hints as for open apply. + +- write: Can simply go, all defined behaviour is taken care of by the framework, + i.e. ping on write and magic char ('V') handling. + +- ioctl: While the driver is allowed to have extensions to the IOCTL interface, + the most common ones are handled by the framework, supported by some assistance + from the driver: + + WDIOC_GETSUPPORT: + Returns the mandatory watchdog_info struct from the driver + + WDIOC_GETSTATUS: + Needs the status-callback defined, otherwise returns 0 + + WDIOC_GETBOOTSTATUS: + Needs the bootstatus member properly set. Make sure it is 0 if you + don't have further support! + + WDIOC_SETOPTIONS: + No preparations needed + + WDIOC_KEEPALIVE: + If wanted, options in watchdog_info need to have WDIOF_KEEPALIVEPING + set + + WDIOC_SETTIMEOUT: + Options in watchdog_info need to have WDIOF_SETTIMEOUT set + and a set_timeout-callback has to be defined. The core will also + do limit-checking, if min_timeout and max_timeout in the watchdog + device are set. All is optional. + + WDIOC_GETTIMEOUT: + No preparations needed + + Other IOCTLs can be served using the ioctl-callback. Note that this is mainly + intended for porting old drivers; new drivers should not invent private IOCTLs. + Private IOCTLs are processed first. When the callback returns with + -ENOIOCTLCMD, the IOCTLs of the framework will be tried, too.

The rest can go. + + +Remove the miscdevice +--------------------- + +Since the file_operations are gone now, you can also remove the 'struct +miscdevice'. The framework will create it on watchdog_dev_register() called by +watchdog_register_device(). + +-static struct miscdevice s3c2410wdt_miscdev = { +- .minor = WATCHDOG_MINOR, +- .name = "watchdog", +- .fops = &s3c2410wdt_fops, +-}; + + +Remove obsolete includes and defines +------------------------------------ + +Because of the simplifications, a few defines are probably unused now.

You can find it +explained in 'watchdog-kernel-api.txt' in this directory. start(), stop() and +owner must be set, the rest are optional. You will easily find corresponding +functions in the old driver. Note that you will now get a pointer to the +watchdog_device as a parameter to these functions, so you probably have to +change the function header. Other changes are most likely not needed, because +here simply happens the direct hardware access. If you have device-specific +code left from the above steps, it should be refactored into these callbacks. + +Here is a simple example: + ++static struct watchdog_ops s3c2410wdt_ops = { ++ .owner = THIS_MODULE, ++ .start = s3c2410wdt_start, ++ .stop = s3c2410wdt_stop, ++ .ping = s3c2410wdt_keepalive, ++ .set_timeout = s3c2410wdt_set_heartbeat, ++}; + +A typical function-header change looks like: + +-static void s3c2410wdt_keepalive(void) ++static int s3c2410wdt_keepalive(struct watchdog_device *wdd) + { +... ++ ++ return 0; + } + +... + +- s3c2410wdt_keepalive(); ++ s3c2410wdt_keepalive(&s3c2410_wdd); + + +Add the watchdog device +----------------------- + +Now we need to create a 'struct watchdog_device' and populate it with the +necessary information for the framework. The struct is also explained in detail +in 'watchdog-kernel-api.txt' in this directory. We pass it the mandatory +watchdog_info struct and the newly created watchdog_ops. Often, old drivers +have their own record-keeping for things like bootstatus and timeout using +static variables. Those have to be converted to use the members in +watchdog_device.
