As we may try to power down the link at various times, it is not necessarily still coupled with an encoder and so we must be careful not to depend upon an operation that is only valid when the link is still attached to a pipe.

In order for bos to retire eventually, a request must be sent down the ring. This is expected, for example, by occlusion queries for which mesa will wait upon (whilst running glean) before issuing more batches and so the normal activity upon the ring is suspended and we need to emit a request to clear the idle ring.

Linus Torvalds pointed out that our code was unbalanced when powering on the panel with respect to the power off sequence in that we were failing to restore the panel-fitter. The consequence of this would be that across a simple DPMS off/on for a non-native mode, without an intervening modeset, the panel fitter would remain disabled and the output would shift on the panel.

There's not much we can do here but hope for the best. However the first failure happens quite frequently and if often remedied by the second attempt to reset HEAD.

Otherwise we can't really fix the abi-braindeadness of forcing libva to manually wait for rendering when switching rings.

ConnectX firmware is supposed to report the number blue flame registers per page as log2 of the value. However, due to a firmware bug, it reports actual number. This patch works around this by checking if the number of registers calculated fits within a page. If it does not, we use 8 registers per page.

Recent tests writing lots of small files showed the flusher thread being CPU bound and taking a long time to do allocations on a debug kernel. perf showed this as the prime reason: samples pcnt function DSO _______ _____ ___________________________ _________________ 224648.00 36.8% xfs_error_test [kernel.kallsyms] 86045.00 14.1% xfs_btree_check_sblock [kernel.kallsyms] 39778.00 6.5% prandom32 [kernel.kallsyms] 37436.00 6.1% xfs_btree_increment [kernel.kallsyms] 29278.00 4.8% xfs_btree_get_rec [kernel.kallsyms] 27717.00 4.5% random32 [kernel.kallsyms] Walking btree blocks during allocation checking them requires each block (a cache hit, so no I/O) call xfs_error_test(), which then does a random32() call as the first operation. IOWs, ~50% of the CPU is being consumed just testing whether we need to inject an error, even though error injection is not active.

When an inode has been marked stale because the cluster is being freed, we don't want to (re-)insert this inode into the AIL. There is a race condition where the cluster buffer may be unpinned before the inode is inserted into the AIL during transaction committed processing. If the buffer is unpinned before the inode item has been committed and inserted, then it is possible for the buffer to be released and hence processthe stale inode callbacks before the inode is inserted into the AIL. In this case, we then insert a clean, stale inode into the AIL which will never get removed by an IO completion. It will, however, get reclaimed and that triggers an assert in xfs_inode_free() complaining about freeing an inode still in the AIL. This race can be avoided by not moving stale inodes forward in the AIL during transaction commit completion processing. This closes the race condition by ensuring we never insert clean stale inodes into the AIL. It is safe to do this because a dirty stale inode, by definition, must already be in the AIL.

There is an assumption in the parts of XFS that flushing a dirty file will make all the delayed allocation blocks disappear from an inode. That is, that after calling xfs_flush_pages() then ip->i_delayed_blks will be zero. This is an invalid assumption as we may have specualtive preallocation beyond EOF and they are recorded in ip->i_delayed_blks. A flush of the dirty pages of an inode will not change the state of these blocks beyond EOF, so a non-zero deeelalloc block count after a flush is valid. The bmap code has an invalid ASSERT() that needs to be removed, and the swapext code has a bug in that while it swaps the data forks around, it fails to swap the i_delayed_blks counter associated with the fork and hence can get the block accounting wrong.

As reported by Nick Piggin, XFS is suffering from long pauses under highly concurrent workloads when hosted on ramdisks. The problem is that an inode buffer is stuck in the pinned state in memory and as a result either the inode buffer or one of the inodes within the buffer is stopping the tail of the log from being moved forward. The system remains in this state until a periodic log force issued by xfssyncd causes the buffer to be unpinned. The main problem is that these are stale buffers, and are hence held locked until the transaction/checkpoint that marked them state has been committed to disk. When the filesystem gets into this state, only the xfssyncd can cause the async transactions to be committed to disk and hence unpin the inode buffer. This problem was encountered when scaling the busy extent list, but only the blocking lock interface was fixed to solve the problem. Extend the same fix to the buffer trylock operations - if we fail to lock a pinned, stale buffer, then force the log immediately so that when the next attempt to lock it comes around, it will have been unpinned.

Since the move to the new truncate sequence we call xfs_setattr to truncate down excessively instanciated blocks. As shown by the testcase in kernel.org BZ #22452 that doesn't work too well. Due to the confusion of the internal inode size, and the VFS inode i_size it zeroes data that it shouldn't. But full blown truncate seems like overkill here. We only instanciate delayed allocations in the write path, and given that we never released the iolock we can't have converted them to real allocations yet either. The only nasty case is pre-existing preallocation which we need to skip. We already do this for page discard during writeback, so make the delayed allocation block punching a generic function and call it from the failed write path as well as xfs_aops_discard_page. The callers are responsible for ensuring that partial blocks are not truncated away, and that they hold the ilock. Based on a fix originally from Christoph Hellwig. This version used filesystem blocks as the range unit. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
