* [PATCH] Generic HID layer - disable USB HIDJiri Kosina2006-12-08
| | | | | | | | | | | | | This patch is a part of generic HID layer introduction. USB HID is disabled, so that the code split and changes could be introduced in a way that is reviewable (i.e. separate patches), but not to break git bisect by uncompilable kernel throughout different stages of the code splitup and changes. The last patch of this series enables HID again.

* | [PATCH] dm: mpath: use noflush suspendingKiyoshi Ueda2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the pushback feature for the multipath target. The pushback request is used when: 1) there are no valid paths; 2) queue_if_no_path was set; 3) a suspend is being issued with the DMF_NOFLUSH_SUSPENDING flag. Otherwise bios are returned to applications with -EIO. To check whether queue_if_no_path is specified or not, you need to check both queue_if_no_path and saved_queue_if_no_path, because presuspend saves the original queue_if_no_path value to saved_queue_if_no_path. The check for 1 already exists in both map_io() and do_end_io(). So this patch adds __must_push_back() to check 2 and 3. Test results: See the test results in the preceding patch.

* | [PATCH] dm: suspend: add noflush pushbackKiyoshi Ueda2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In device-mapper I/O is sometimes queued within targets for later processing. For example the multipath target can be configured to store I/O when no paths are available instead of returning it -EIO. This patch allows the device-mapper core to instruct a target to transfer the contents of any such in-target queue back into the core. This frees up the resources used by the target so the core can replace that target with an alternative one and then resend the I/O to it. Without this patch the only way to change the target in such circumstances involves returning the I/O with an error back to the filesystem/application. In the multipath case, this patch will let us add new paths for existing I/O to try after all the existing paths have failed. DMF_NOFLUSH_SUSPENDING ---------------------- If the DM_NOFLUSH_FLAG ioctl option is specified at suspend time, the DMF_NOFLUSH_SUSPENDING flag is set in md->flags during dm_suspend(). It is always cleared before dm_suspend() returns. The flag must be visible while the target is flushing pending I/Os so it is set before presuspend where the flush starts and unset after the wait for md->pending where the flush ends. Target drivers can check this flag by calling dm_noflush_suspending(). DM_MAPIO_REQUEUE / DM_ENDIO_REQUEUE ----------------------------------- A target's map() function can now return DM_MAPIO_REQUEUE to request the device mapper core queue the bio. Similarly, a target's end_io() function can return DM_ENDIO_REQUEUE to request the same. This has been labelled 'pushback'. The __map_bio() and clone_endio() functions in the core treat these return values as errors and call dec_pending() to end the I/O. dec_pending ----------- dec_pending() saves the pushback request in struct dm_io->error. Once all the split clones have ended, dec_pending() will put the original bio on the md->pushback list. Note that this supercedes any I/O errors. It is possible for the suspend with DM_NOFLUSH_FLAG to be aborted while in progress (e.g. by user interrupt). dec_pending() checks for this and returns -EIO if it happened. pushdback list and pushback_lock -------------------------------- The bio is queued on md->pushback temporarily in dec_pending(), and after all pending I/Os return, md->pushback is merged into md->deferred in dm_suspend() for re-issuing at resume time. md->pushback_lock protects md->pushback. The lock should be held with irq disabled because dec_pending() can be called from interrupt context. Queueing bios to md->pushback in dec_pending() must be done atomically with the check for DMF_NOFLUSH_SUSPENDING flag. So md->pushback_lock is held when checking the flag. Otherwise dec_pending() may queue a bio to md->pushback after the interrupted dm_suspend() flushes md->pushback. Then the bio would be left in md->pushback. Flag setting in dm_suspend() can be done without md->pushback_lock because the flag is checked only after presuspend and the set value is already made visible via the target's presuspend function. The flag can be checked without md->pushback_lock (e.g. the first part of the dec_pending() or target drivers), because the flag is checked again with md->pushback_lock held when the bio is really queued to md->pushback as described above. So even if the flag is cleared after the lockless checkings, the bio isn't left in md->pushback but returned to applications with -EIO. Other notes on the current patch -------------------------------- - md->pushback is added to the struct mapped_device instead of using md->deferred directly because md->io_lock which protects md->deferred is rw_semaphore and can't be used in interrupt context like dec_pending(), and md->io_lock protects the DMF_BLOCK_IO flag of md->flags too. - Don't issue lock_fs() in dm_suspend() if the DM_NOFLUSH_FLAG ioctl option is specified, because I/Os generated by lock_fs() would be pushed back and never return if there were no valid devices. - If an error occurs in dm_suspend() after the DMF_NOFLUSH_SUSPENDING flag is set, md->pushback must be flushed because I/Os may be queued to the list already. (flush_and_out label in dm_suspend()) Test results ------------ I have tested using multipath target with the next patch. The following tests are for regression/compatibility: - I/Os succeed when valid paths exist; - I/Os fail when there are no valid paths and queue_if_no_path is not set; - I/Os are queued in the multipath target when there are no valid paths and queue_if_no_path is set; - The queued I/Os above fail when suspend is issued without the DM_NOFLUSH_FLAG ioctl option. I/Os spanning 2 multipath targets also fail. The following tests are for the normal code path of new pushback feature: - Queued I/Os in the multipath target are flushed from the target but don't return when suspend is issued with the DM_NOFLUSH_FLAG ioctl option; - The I/Os above are queued in the multipath target again when resume is issued without path recovery; - The I/Os above succeed when resume is issued after path recovery or table load; - Queued I/Os in the multipath target succeed when resume is issued with the DM_NOFLUSH_FLAG ioctl option after table load. I/Os spanning 2 multipath targets also succeed. The following tests are for the error paths of the new pushback feature: - When the bdget_disk() fails in dm_suspend(), the DMF_NOFLUSH_SUSPENDING flag is cleared and I/Os already queued to the pushback list are flushed properly. - When suspend with the DM_NOFLUSH_FLAG ioctl option is interrupted, o I/Os which had already been queued to the pushback list at the time don't return, and are re-issued at resume time; o I/Os which hadn't been returned at the time return with EIO.

Values of 2 and above are now explictly reserved for future use. There are no existing targets using such values. The patch has no effect on existing behaviour. o Reserve return values of 2 and above from target map functions. Any positive value currently indicates "mapping complete", but all existing drivers use the value 1. We now make that a requirement so we can assign new meaning to higher values in future. The new definition of return values from target map functions is: < 0 : error = 0 : The target will handle the io (DM_MAPIO_SUBMITTED). = 1 : Mapping completed (DM_MAPIO_REMAPPED). > 1 : Reserved (undefined). Previously this was the same as '= 1'. o Reserve return values of 2 and above from target end_io functions for similar reasons. DM_ENDIO_INCOMPLETE is introduced for a return value of 1. Test results: I have tested by using the multipath target. I/Os succeed when valid paths exist. I/Os are queued in the multipath target when there are no valid paths and queue_if_no_path is set. I/Os fail when there are no valid paths and queue_if_no_path is not set.

* | [PATCH] backlight: do not power off backlight when unregisteringHenrique de Moraes Holschuh2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACPI drivers like ibm-acpi are moving to the backlight sysfs infrastructure. During ibm-acpi testing, I have noticed that backlight_device_unregister() sets the display brightness and power to zero. This causes the display to be dimmed on ibm-acpi module removal. It will affect all other ACPI drivers that are being converted to use the backlight class, as well. It also affects a number of framebuffer devices that are used on desktops and laptops which might also not want such behaviour. Since working around this behaviour requires undesireable hacks, Richard Purdie decided that we would be better off reverting the changes in the sysfs class, and adding the code to dim and power off the backlight device to the drivers that want it. This patch is my attempt to do so. Patch against latest linux-2.6.git. Changes untested, as I lack the required hardware. Still, they are trivial enough that, apart from typos, there is little chance of getting them wrong.

* | [PATCH] softcursor.c: avoid unaligned accessesFranck Bui-Huu2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix some possible unaligned accesses when accessing fields of 'image' pointer. Indeed this pointer was obtained by allocating a block of memory that embeds a temporary array plus an image structure. The temporary buffer was located at the start of the allocated block and depending on its size, the image structure which comes right after can be unaligned. For example when using mini fonts (4x6) (cursor's width is 4 and its height is 6) the temporary buf size is 6 bytes. Therefore this patch moves the image structure to the start of the block and moves the temporary buffer right after. It makes 'image' pointer always aligned and since the tempo buf is a buffer of char, it's always correctly aligned as well. It also fixes the file header alignement.

* | [PATCH] atyfb: Improve power managementVille Syrjala2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | Some register were only set in aty_init() which is not called on resume. I added the aty_resume_chip() function to reset those registers on resume. Susped-to-ram now works on a HP Omnibook 6000 with acpi_sleep=s3_bios. Signed-off-by: Ville Syrjala <syrjala@sci.fi> Cc: "Antonino A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a way to create and use the video plane (YUV overlay) and scaling video scaling features of the chip. The overlay is configured, resized and modified using a device specific ioctl. Also included in this patch: - If no platform data was passed, print an error and exit instead of crashing. - Added a write_reg(_dly) macro. This improves readability when manipulating chip registers. (no more udelay() after each write). - Comments about some issues. Signed-off-by: Raphael Assenat <raph@8d.com> Cc: "Antonino A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for stn displays on the s3c2410 arm SoC. The LCD type is choosen by a new field in the s3c2410fb_mach_info structure and its value is the value of the PNRMODE bits. This worth to be noted as a value of 0 means that you configure a 4 bit dual scan stn display. Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Cc: "Antonino A.
