[PATCH v5 1/3] drm/shmem: add support for per object caching flags.

by Gerd Hoffmann

Add map_cached bool to drm_gem_shmem_object, to request cached mappings on a per-object base. Check the flag before adding writecombine to pgprot bits.

[PATCH 1/2] drm/i915/gt: Detect if we miss WaIdleLiteRestore

by Chris Wilson

Upstream: 82c69bf58650 ("drm/i915/gt: Detect if we miss WaIdleLiteRestore") In order to avoid confusing the HW, we must never submit an empty ring during lite-restore, that is we should always advance the RING_TAIL before submitting to stay ahead of the RING_HEAD. Normally this is prevented by keeping a couple of spare NOPs in the request->wa_tail so that on resubmission we can advance the tail. This relies on the request only being resubmitted once, which is the normal condition as it is seen once for ELSP[1] and then later in ELSP[0]. On preemption, the requests are unwound and the tail reset back to the normal end point (as we know the request is incomplete and therefore its RING_HEAD is even earlier). However, if this w/a should fail we would try and resubmit the request with the RING_TAIL already set to the location of this request's wa_tail potentially causing a GPU hang. We can spot when we do try and incorrectly resubmit without advancing the RING_TAIL and spare any embarrassment by forcing the context restore. In the case of preempt-to-busy, we leave the requests running on the HW while we unwind. As the ring is still live, we cannot rewind our rq->tail without forcing a reload so leave it set to rq->wa_tail and only force a reload if we resubmit after a lite-restore. (Normally, the forced reload will be a part of the preemption event.)

5.4-stable request: 52e29e331070cd ('btrfs: don't set path->leave_spinning for truncate')

by Holger Hoffstätte

Hi, I was just looking throught the current 5.4-stable queue and saw that 28553fa992cb28 ('Btrfs: fix race between shrinking truncate and fiemap') is queued. Upstream has a follow-up fix for this: 52e29e331070cd aka 'btrfs: don't set path->leave_spinning for truncate'. Would be nice to get those in together. I only looked at 5.4, don't know about other queues. thanks, Holger

FAILED: patch "[PATCH] Btrfs: fix deadlock during fast fsync when logging prealloc" failed to apply to 4.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From a5ae50dea9111db63d30d700766dd5509602f7ad Mon Sep 17 00:00:00 2001 From: Filipe Manana <fdmanana(a)suse.com> Date: Thu, 20 Feb 2020 13:29:49 +0000 Subject: [PATCH] Btrfs: fix deadlock during fast fsync when logging prealloc extents beyond eof While logging the prealloc extents of an inode during a fast fsync we call btrfs_truncate_inode_items(), through btrfs_log_prealloc_extents(), while holding a read lock on a leaf of the inode's root (not the log root, the fs/subvol root), and then that function locks the file range in the inode's iotree. This can lead to a deadlock when: * the fsync is ranged * the file has prealloc extents beyond eof * writeback for a range different from the fsync range starts during the fsync * the size of the file is not sector size aligned Because when finishing an ordered extent we lock first a file range and then try to COW the fs/subvol tree to insert an extent item. The following diagram shows how the deadlock can happen. CPU 1 CPU 2 btrfs_sync_file() --> for range [0, 1MiB) --> inode has a size of 1MiB and has 1 prealloc extent beyond the i_size, starting at offset 4MiB flushes all delalloc for the range [0MiB, 1MiB) and waits for the respective ordered extents to complete --> before task at CPU 1 locks the inode, a write into file range [1MiB, 2MiB + 1KiB) is made --> i_size is updated to 2MiB + 1KiB --> writeback is started for that range, [1MiB, 2MiB + 4KiB) --> end offset rounded up to be sector size aligned btrfs_log_dentry_safe() btrfs_log_inode_parent() btrfs_log_inode() btrfs_log_changed_extents() btrfs_log_prealloc_extents() --> does a search on the inode's root --> holds a read lock on leaf X btrfs_finish_ordered_io() --> locks range [1MiB, 2MiB + 4KiB) --> end offset rounded up to be sector size aligned --> tries to cow leaf X, through insert_reserved_file_extent() --> already locked by the task at CPU 1 btrfs_truncate_inode_items() --> gets an i_size of 2MiB + 1KiB, which is not sector size aligned --> tries to lock file range [2MiB, (u64)-1) --> the start range is rounded down from 2MiB + 1K to 2MiB to be sector size aligned --> but the subrange [2MiB, 2MiB + 4KiB) is already locked by task at CPU 2 which is waiting to get a write lock on leaf X for which we are holding a read lock *** deadlock *** This results in a stack trace like the following, triggered by test case generic/561 from fstests: [ 2779.973608] INFO: task kworker/u8:6:247 blocked for more than 120 seconds.
