2012-08-29drm/radeon/atom: rework DIG modesetting on DCE3+Alex Deucher
The ordering is important and the current drm code wasn't cutting it for modern DIG encoders. We need to have information about crtc before setting up the encoders so I've shifted the ordering a bit. Probably we'll need a full rework akin to danvet's recent intel patchs. This patch fixes numerous issues with DP bridge chips and makes link training much more reliable.

2012-08-29drm/radeon: add proper checking of RESOLVE_BOX command for r600-r700Marek Olšák
Checking of the second colorbuffer was skipped on r700, because CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff, so we must set the number of samples of the second colorbuffer to 1 in order to pass the CS checker. The DRM version is bumped, because RESOLVE_BOX is always rejected without this fix on r600.

2012-08-28Btrfs: fix that repair code is spuriously executed for transid failuresStefan Behrens
If verify_parent_transid() fails for all mirrors, the current code calls repair_io_failure() anyway which means: - that the disk block is rewritten without repairing anything and - that a kernel log message is printed which misleadingly claims that a read error was corrected. This is an example: parent transid verify failed on 615015833600 wanted 110423 found 110424 parent transid verify failed on 615015833600 wanted 110423 found 110424 btrfs read error corrected: ino 1 off 615015833600 (dev /dev/...) It is wrong to ignore the results from verify_parent_transid() and to call repair_eb_io_failure() when the verification of the transids failed. This commit fixes the issue.

2012-08-28Btrfs: revert checksum error statistic which can cause a BUG()Stefan Behrens
Commit 442a4f6308e694e0fa6025708bd5e4e424bbf51c added btrfs device statistic counters for detected IO and checksum errors to Linux 3.5. The statistic part that counts checksum errors in end_bio_extent_readpage() can cause a BUG() in a subfunction: "kernel BUG at fs/btrfs/volumes.c:3762!" That part is reverted with the current patch. However, the counting of checksum errors in the scrub context remains active, and the counting of detected IO errors (read, write or flush errors) in all contexts remains active.

2012-08-28Btrfs: remove superblock writing after fatal errorStefan Behrens
With commit acce952b0, btrfs was changed to flag the filesystem with BTRFS_SUPER_FLAG_ERROR and switch to read-only mode after a fatal error happened like a write I/O errors of all mirrors. In such situations, on unmount, the superblock is written in btrfs_error_commit_super(). This is done with the intention to be able to evaluate the error flag on the next mount. A warning is printed in this case during the next mount and the log tree is ignored. The issue is that it is possible that the superblock points to a root that was not written (due to write I/O errors). The result is that the filesystem cannot be mounted. btrfsck also does not start and all the other btrfs-progs tools fail to start as well. However, mount -o recovery is working well and does the right things to recover the filesystem (i.e., don't use the log root, clear the free space cache and use the next mountable root that is stored in the root backup array). This patch removes the writing of the superblock when BTRFS_SUPER_FLAG_ERROR is set, and removes the handling of the error flag in the mount function. These lines can be used to reproduce the issue (using /dev/sdm): SCRATCH_DEV=/dev/sdm SCRATCH_MNT=/mnt echo 0 25165824 linear $SCRATCH_DEV 0 | dmsetup create foo ls -alLF /dev/mapper/foo mkfs.btrfs /dev/mapper/foo mount /dev/mapper/foo $SCRATCH_MNT echo bar > $SCRATCH_MNT/foo sync echo 0 25165824 error | dmsetup reload foo dmsetup resume foo ls -alF $SCRATCH_MNT touch $SCRATCH_MNT/1 ls -alF $SCRATCH_MNT sleep 35 echo 0 25165824 linear $SCRATCH_DEV 0 | dmsetup reload foo dmsetup resume foo sleep 1 umount $SCRATCH_MNT btrfsck /dev/mapper/foo dmsetup remove foo Signed-off-by: Stefan Behrens <sbehrens@giantdisaster.de> Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
2012-08-28Btrfs: allow delayed refs to be mergedJosef Bacik
Daniel Blueman reported a bug with fio+balance on a ramdisk setup. Basically what happens is the balance relocates a tree block which will drop the implicit refs for all of its children and adds a full backref. Once the block is relocated we have to add the implicit refs back, so when we cow the block again we add the implicit refs for its children back. The problem comes when the original drop ref doesn't get run before we add the implicit refs back. The delayed ref stuff will specifically prefer ADD operations over DROP to keep us from freeing up an extent that will have references to it, so we try to add the implicit ref before it is actually removed and we panic. This worked fine before because the add would have just canceled the drop out and we would have been fine. But the backref walking work needs to be able to freeze the delayed ref stuff in time so we have this ever increasing sequence number that gets attached to all new delayed ref updates which makes us not merge refs and we run into this issue. So to fix this we need to merge delayed refs. So everytime we run a clustered ref we need to try and merge all of its delayed refs. The backref walking stuff locks the delayed ref head before processing, so if we have it locked we are safe to merge any refs inside of the sequence number. If there is no sequence number we can merge all refs. Doing this not only fixes our bug but keeps the delayed ref code from adding and removing useless refs and batching together multiple refs into one search instead of one search per delayed ref, which will really help our commit times. I ran this with Daniels test and 276 and I haven't seen any problems. Thanks, Reported-by: Daniel J Blueman <daniel@quora.org> Signed-off-by: Josef Bacik <jbacik@fusionio.com>
2012-08-28Btrfs: fix enospc problems when deleting a subvolJosef Bacik
Subvol delete is a special kind of awful where we use the global reserve to cover the ENOSPC requirements. The problem is once we're done removing everything we do a btrfs_update_inode(), which by default will try to do the delayed update stuff which will use it's own reserve. There will be no space in this reserve and we'll return ENOSPC. So instead use btrfs_update_inode_fallback() which will just fallback to updating the inode item in the case of enospc. This is fine because the global reserve covers the space requirements for this. With this patch I can now delete a subvol on a problem image Dave Sterba sent me.

2012-08-28Btrfs: increase the size of the free space cacheJosef Bacik
Arne was complaining about the space cache having mismatching generation numbers when debugging a deadlock. This is because we can run out of space in our preallocated range for our space cache if you have a pretty fragmented amount of space in your pinned space. So just increase the amount of space we preallocate for space cache so we can be sure to have enough space. This will only really affect data ranges since their the only chunks that end up larger than 256MB.

2012-08-28Btrfs: barrier before waitqueue_activeJosef Bacik
We need a barrir before calling waitqueue_active otherwise we will miss wakeups.

2012-08-28Btrfs: fix deadlock in wait_for_more_refsArne Jansen
Commit a168650c introduced a waiting mechanism to prevent busy waiting in btrfs_run_delayed_refs. This can deadlock with btrfs_run_ordered_operations, where a tree_mod_seq is held while waiting for the io to complete, while the end_io calls btrfs_run_delayed_refs. This whole mechanism is unnecessary. If not enough runnable refs are available to satisfy count, just return as count is more like a guideline than a strict requirement. In case we have to run all refs, commit transaction makes sure that no other threads are working in the transaction anymore, so we just assert here that no refs are blocked.

2012-08-28Btrfs: don't allocate a seperate csums array for direct readsJosef Bacik
We've been allocating a big array for csums instead of storing them in the io_tree like we do for buffered reads because previously we were locking the entire range, so we didn't have an extent state for each sector of the range. But now that we do the range locking as we map the buffers we can limit the mapping lenght to sectorsize and use the private part of the io_tree for our csums. This allows us to avoid an extra memory allocation for direct reads which could incur latency. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

2012-08-28Btrfs: lock extents as we map them in DIOJosef Bacik
A deadlock in xfstests 113 was uncovered by commit d187663ef24cd3d033f0cbf2867e70b36a3a90b8 This is because we would not return EIOCBQUEUED for short AIO reads, instead we'd wait for the DIO to complete and then return the amount of data we transferred, which would allow our stuff to unlock the remaning amount. But with this change this no longer happens, so if we have a short AIO read (for example if we try to read past EOF), we could leave the section from EOF to the end of where we tried to read locked. Fixing this is tricky since there is no clear way to know exactly how much data DIO truly submitted for IO, so to make this less hard on ourselves and less combersome we need to lock the extents as we try to map them, and then we unlock any areas we didn't actually map. This makes us completely safe from deadlocks and reliance on a particular behavior of the DIO code. This also lays the groundwork for allowing us to use the normal csum storage method for reads which means we can remove an allocation. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

Pull MIPS fixes from Ralf Baechle: "Random fixes across the MIPS tree. The two hotspots are several bugs in the module loader and the ath79 SOC support; also noteworthy is the restructuring of the code to synchronize CPU timers across CPUs on startup; the old code recently ceased to work due to unrelated changes. All except one of these patches have sat for a significant time in linux-next for testing." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: pci-ar724x: avoid data bus error due to a missing PCIe module MIPS: Malta: Delete duplicate PCI fixup.

Pull block-related fixes from Jens Axboe: - Improvements to the buffered and direct write IO plugging from Fengguang. - Abstract out the mapping of a bio in a request, and use that to provide a blk_bio_map_sg() helper. Useful for mapping just a bio instead of a full request. - Regression fix from Hugh, fixing up a patch that went into the previous release cycle (and marked stable, too) attempting to prevent a loop in __getblk_slow(). - Updates to discard requests, fixing up the sizing and how we align them. Also a change to disallow merging of discard requests, since that doesn't really work properly yet. - A few drbd fixes. - Documentation updates. * 'for-linus' of git://git.kernel.dk/linux-block: block: replace __getblk_slow misfix by grow_dev_page fix drbd: Write all pages of the bitmap after an online resize drbd: Finish requests that completed while IO was frozen drbd: fix drbd wire compatibility for empty flushes Documentation: update tunable options in block/cfq-iosched.txt Documentation: update tunable options in block/cfq-iosched.txt Documentation: update missing index files in block/00-INDEX block: move down direct IO plugging block: remove plugging at buffered write time block: disable discard request merge temporarily bio: Fix potential memory leak in bio_find_or_create_slab() block: Don't use static to define "void *p" in show_partition_start() block: Add blk_bio_map_sg() helper block: Introduce __blk_segment_map_sg() helper fs/block-dev.c:fix performance regression in O_DIRECT writes to md block devices block: split discard into aligned requests block: reorganize rounding of max_discard_sectors
