* ptp: Added a brand new class driver for ptp clocks.Richard Cochran2011-05-238-0/+863
| | | | | | | | | | | | | | | This patch adds an infrastructure for hardware clocks that implement IEEE 1588, the Precision Time Protocol (PTP). A class driver offers a registration method to particular hardware clock drivers. Each clock is presented as a standard POSIX clock. The ancillary clock features are exposed in two different ways, via the sysfs and by a character device.

| * | md: allow resync_start to be set while an array is active.NeilBrown2011-05-113-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sysfs attribute 'resync_start' (known internally as recovery_cp), records where a resync is up to. A value of 0 means the array is not known to be in-sync at all. A value of MaxSector means the array is believed to be fully in-sync. When the size of member devices of an array (RAID1,RAID4/5/6) is increased, the array can be increased to match. This process sets resync_start to the old end-of-device offset so that the new part of the array gets resynced. However with RAID1 (and RAID6) a resync is not technically necessary and may be undesirable. So it would be good if the implied resync after the array is resized could be avoided. So: change 'resync_start' so the value can be changed while the array is active, and as a precaution only allow it to be changed while resync/recovery is 'frozen'. Changing it once resync has started is not going to be useful anyway. This allows the array to be resized without a resync by: write 'frozen' to 'sync_action' write new size to 'component_size' (this will set resync_start) write 'none' to 'resync_start' write 'idle' to 'sync_action'. Also slightly improve some tests on recovery_cp when resizing raid1/raid5. Now that an arbitrary value could be set we should be more careful in our tests. Signed-off-by: NeilBrown <neilb@suse.de>
| * | md/raid10: reformat some loops with less indenting.NeilBrown2011-05-111-108/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a loop ends with an 'if' with a large body, it is neater to make the if 'continue' on the inverse condition, and then the body is indented less.

| * | md/raid10: some tidying up in fix_read_errorNeilBrown2011-05-111-40/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the rdev on which a read error happened could be removed before we perform the fix_error handling. This requires extra tests for NULL. So delay the rdev_dec_pending call until after the call to fix_read_error so that we can be sure that the rdev still exists. This allows an 'if' clause to be removed so the body gets re-indented back one level. Signed-off-by: NeilBrown <neilb@suse.de>
| * | md/raid1: improve handling of pages allocated for write-behind.NeilBrown2011-05-112-30/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current handling and freeing of these pages is a bit fragile. We only keep the list of allocated pages in each bio, so we need to still have a valid bio when freeing the pages, which is a bit clumsy. So simply store the allocated page list in the r1_bio so it can easily be found and freed when we are finished with the r1_bio. Signed-off-by: NeilBrown <neilb@suse.de>
| * | md/raid1: try fix_sync_read_error before process_checks.NeilBrown2011-05-111-14/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we get a read error during resync/recovery we current repeat with single-page reads to find out just where the error is, and possibly read each page from a different device. With check/repair we don't currently do that, we just fail. However it is possible that while all devices fail on the large 64K read, we might be able to satisfy each 4K from one device or another. So call fix_sync_read_error before process_checks to maximise the chance of finding good data and writing it out to the devices with read errors. For this to work, we need to set the 'uptodate' flags properly after fix_sync_read_error has succeeded. Signed-off-by: NeilBrown <neilb@suse.de>
| * | md/raid1: tidy up new functions: process_checks and fix_sync_read_error.NeilBrown2011-05-111-89/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes are mostly cosmetic: 1/ change mddev->raid_disks to conf->raid_disks because the later is technically safer, though in current practice it doesn't matter in this particular context. 2/ Rearrange two for / if loops to have an early 'continue' so the body of the 'if' doesn't need to be indented so much.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | read_balance has two loops which both look for a 'best' device based on slightly different criteria.

| * | md/bitmap: fix saving of events_cleared and other state.NeilBrown2011-05-111-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a bitmap is found to be 'stale' the events_cleared value is set to match 'events'. However if the array is degraded this does not get stored on disk. This can subsequently lead to incorrect behaviour. So change bitmap_update_sb to always update events_cleared in the superblock from the known events_cleared. For neatness also set ->state from ->flags. This requires updating ->state whenever we update ->flags, which makes sense anyway. This is suitable for any active -stable release. cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
| * | md: reject a re-add request that cannot be honoured.NeilBrown2011-05-111-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'add_new_disk' ioctl can be used to add a device either as a spare, or as an active disk that just needs to be resynced based on write-intent-bitmap information (re-add) Currently if a re-add is requested but fails we add as a spare instead. This makes it impossible for user-space to check for failure. So change to require that a re-add attempt will either succeed or completely fail. User-space can then decide what to do next.

| * | md: Fix race when creating a new md device.NeilBrown2011-05-111-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race when creating an md device by opening /dev/mdXX. If two processes do this at much the same time they will follow the call path __blkdev_get -> get_gendisk -> kobj_lookup The first will call -> md_probe -> md_alloc -> add_disk -> blk_register_region and the race happens when the second gets to kobj_lookup after add_disk has called blk_register_region but before it returns to md_alloc. In the case the second will not call md_probe (as the probe is already done) but will get a handle on the gendisk, return to __blkdev_get which will then call md_open (via the ->open) pointer. As mddev->gendisk hasn't been set yet, md_open will think something is wrong an return with ERESTARTSYS. This can loop endlessly while the first thread makes no progress through add_disk. Nothing is blocking it, but due to scheduler behaviour it doesn't get a turn. So this is essentially a live-lock. We fix this by simply moving the assignment to mddev->gendisk before the call the add_disk() so md_open doesn't get confused. Also move blk_queue_flush earlier because add_disk should be as late as possible. To make sure that md_open doesn't complete until md_alloc has done all that is needed, we take mddev->open_mutex during the last part of md_alloc. md_open will wait for this. This can cause a lock-up on boot so Cc:ing for stable. For 2.6.36 and earlier a different patch will be needed as the 'blk_queue_flush' call isn't there.

| | * | | | viafb: remove unused max_hres/vresFlorian Tobias Schandinat2011-03-232-137/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the max_hres and max_vres which are not used at the moment. In general they could be useful but it would be better to get them via any standard EDID implementation and not the buggy incomplete one currently used which is also removed as far as possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the iga path is the only remaining information which is also handled by the active devices there is no reason to keep it. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

| * | | | viafb: reduce OLPC refresh a bitFlorian Tobias Schandinat2011-04-243-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When allowing some PLL calculation we get a frequency that seems to be a bit higher than what the OLPC DCON likes resulting in a still readable but not so good image. We don't really know whether this is a problem with the calculation formula or the OLPC but as other displays seem to be happy with the other modes adjusting the OLPC refresh looks like the better thing. This patch prevents a regression when dynamic PLL calculation is allowed. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
| * | | | viafb: fix OLPC XO 1.5 device connectionFlorian Tobias Schandinat2011-04-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the devices connected on OLPC. The OLPC panel seems to be connected to DVP1 and LVDS2 for some reasons and if not both are handled correct the display does not work correct or not at all. This patch prevents regressions on the OLPC where it worked by accident but would break in future as the driver did not know the correct devices connected. This might also fix hardware scaling. Hopefully the OLPC is the only device with such a requirement but it will be certainly better to actually know what devices are actually connected and to not work by accident.
