Fix the MST sideband message body length check, which must be at least 1
byte accounting for the message body CRC (aka message data CRC) at the
end of the message.

This fixes a case where an MST branch device returns a header with a
correct header CRC (indicating a correctly received body length), with
the body length being incorrectly set to 0. This will later lead to a
memory corruption in drm_dp_sideband_append_payload() and the following
errors in dmesg:

The function silently assumed that signaling was already enabled for the
dma_fence_array. This meant that without enabling signaling first we would
never see forward progress.

Fix that by falling back to testing each individual fence when signaling
isn't enabled yet.

Tvrtko Ursulin authored 4 months ago and Christian König committed 4 months ago

One alternative to the fix Christian proposed in
https://lore.kernel.org/dri-devel/20241024124159.4519-3-christian.koenig@amd.com/


is to replace the rather complex open coded sorting loops with the kernel
standard sort followed by a context squashing pass.

Proposed advantage of this would be readability but one concern Christian
raised was that there could be many fences, that they are typically mostly
sorted, and so the kernel's heap sort would be much worse by the proposed
algorithm.

I had a look running some games and vkcube to see what are the typical
number of input fences. Tested scenarios:

1) Hogwarts Legacy under Gamescope

450 calls per second to __dma_fence_unwrap_merge.

Percentages per number of fences buckets, before and after checking for
signalled status, sorting and flattening:

   N       Before      After
   0       0.91%
   1      69.40%
  2-3     28.72%       9.4%  (90.6% resolved to one fence)
  4-5      0.93%
  6-9      0.03%
  10+

2) Cyberpunk 2077 under Gamescope

1050 calls per second, amounting to 0.01% CPU time according to perf top.

   N       Before      After
   0       1.13%
   1      52.30%
  2-3     40.34%       55.57%
  4-5      1.46%        0.50%
  6-9      2.44%
  10+      2.34%

3) vkcube under Plasma

90 calls per second.

   N       Before      After
   0
   1
  2-3      100%         0%   (Ie. all resolved to a single fence)
  4-5
  6-9
  10+

In the case of vkcube all invocations in the 2-3 bucket were actually
just two input fences.

From these numbers it looks like the heap sort should not be a
disadvantage, given how the dominant case is <= 2 input fences which heap
sort solves with just one compare and swap. (And for the case of one input
fence we have a fast path in the previous patch.)

A complementary possibility is to implement a different sorting algorithm
under the same API as the kernel's sort() and so keep the simplicity,
potentially moving the new sort under lib/ if it would be found more
widely useful.

v2:
 * Hold on to fence references and reduce commentary. (Christian)
 * Record and use latest signaled timestamp in the 2nd loop too.
 * Consolidate zero or one fences fast paths.

v3:
 * Reverse the seqno sort order for a simpler squashing pass. (Christian)

This commit fixes the bug in the handling of partial mapping of the
buffer objects to the GPU, which caused kernel warnings.

Panthor didn't correctly handle the case where the partial mapping
spanned multiple scatterlists and the mapping offset didn't point

not cleared after reaching the starting scatterlist.

When the Tx FIFO is empty and the last command has no STOP bit
set, the master holds SCL low. If I2C_DYNAMIC_TAR_UPDATE is not
set, BIT(13) MST_ON_HOLD of IC_RAW_INTR_STAT is not enabled,
causing the __i2c_dw_disable() timeout. This is quite similar to
commit 2409205a ("i2c: designware: fix __i2c_dw_disable() in
case master is holding SCL low"). Also check BIT(7)
MST_HOLD_TX_FIFO_EMPTY in IC_STATUS, which is available when
IC_STAT_FOR_CLK_STRETCH is set.

Fixes: 2409205a ("i2c: designware: fix __i2c_dw_disable() in case master is holding SCL low")

Pull bcachefs fixes from Kent Overstreet:
 "Some trivial syzbot fixes, two more serious btree fixes found by
  looping single_devices.ktest small_nodes:

   - Topology error on split after merge, where we accidentaly picked
     the node being deleted for the pivot, resulting in an assertion pop

   - New nodes being preallocated were left on the freedlist, unlocked,
     resulting in them sometimes being accidentally freed: this dated
     from pre-cycle detector, when we could leave them locked. This
     should have resulted in more explosions and fireworks, but turned
     out to be surprisingly hard to hit because the preallocated nodes
     were being used right away.

     The fix for this is bigger than we'd like - reworking btree list
     handling was a bit invasive - but we've now got more assertions and
     it's well tested.

   - Also another mishandled transaction restart fix (in
     btree_node_prefetch) - we're almost done with those"

Pull arm64 fixes from Will Deacon:
 "Here is a (hopefully) final round of arm64 fixes for 6.12 that address
  some user-visible floating point register corruption. Both of the
  Marks have been working on this for a couple of weeks and we've ended
  up in a position where SVE is solid but SME still has enough pending
  issues that the most pragmatic solution for the release and stable
  backports is to disable the feature. Yes, it's a shame, but the
  hardware is rare as hen's teeth at the moment and we're better off
  getting back to a known good state before fixing it all properly.
  We're also improving the selftests for 6.13 to help avoid merging
  broken code in the future.

  Anyway, the good news is that we're removing a lot more code than
  we're adding.

  Summary:

   - Fix handling of SVE traps from userspace on preemptible kernels
     when converting the saved floating point state into SVE state.

   - Remove broken support for the SMCCCv1.3 "SVE discard hint"
     optimisation.

   - Disable SME support, as the current support code suffers from
     numerous issues around signal delivery, ptrace access and
     context-switch which can lead to user-visible corruption of the
     register state"
