kernel dmesg (kernel 5.19-rc2, AMD Ryzen 9 5950X)

Starting with kernel v5.18 series I get a severly garbled screen on my system
and lotsa "[drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed in the dependencies
handling -1431655766!" in dmesg. Kernel v5.19-rc2 still got this flaw.

Kernel dmesg looks like that:
[...]
[drm] Initialized amdgpu 3.47.0 20150101 for 0000:09:00.0 on minor 0
fbcon: amdgpudrmfb (fb0) is primary device

[...]

Apart from that the machine runs fine without X. Xorg.0.log states X also gets
started, seeminlgy without problems.

Kernel v5.17 series was all good so I did a bisect which revealed this as 1st
bad commit:

    Merge tag 'drm-misc-fixes-2022-04-22' of
git://anongit.freedesktop.org/drm/drm-misc into drm-fixes

    Two fixes for the raspberrypi panel initialisation, one fix for a logic
    inversion in radeon, a build and pm refcounting fix for vc4, two reverts
    for drm_of_get_bridge that caused a number of regression and a locking
    regression for amdgpu.

Ok, seems to be commit   94f4c4965e5513ba624488f4b601d6b385635aec drm/amdgpu:
partial revert "remove ctx->lock" v2   specifically.

Reverting it on top of v5.19-rc2 gives me working X again and also the
"[drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed in the dependencies handling
-1431655766!" errors disappear from dmesg.

Had a closer look at the patch as it did not apply on top of v5.19-rc4. Seems
like almost all of the patch diff is already in upstream v5.19-rc4. Only thing
left to patch is:

But applying this on top of v5.19-rc4 does not help either. I still need to

--- Comment #13 from Erhard F. (erhard_f@mailbox.org) ---
Interesting! Found out this is a gcc vs. clang issue.

Using a kernel built with the attached 5.19.4 config with clang-14.0.6 leads to
the issue as described. Using a kernel built with the same config but with
gcc-12.2.0 just works fine!

I'll close here as it's clear this is not strictly an AMD driver issue.

Not really clear; there could be buggy amdgpu driver code, which happens not to
result in noticeable issues in practice when compiled by GCC.

Agreed.

I'll keep it open and check the issue again on new 6.x stable kernel releases
and when clang 15 becomes available.

kernel dmesg (kernel 6.1-rc5, AMD Ryzen 9 5950X)

Reinvestigating on kernel 6.1-rc5 built with clang 15.0.3 + lld 15.0.3.

So far I was not able to reproduce the bug! X runs just fine for now.

I'll close here once 6.1 is stable and I can assure the bug does no longer show
up on my other affected machines (AMD PRO A12-8830B, AMD PRO A10-8750B) too.

--- Comment #18 from Erhard F. (erhard_f@mailbox.org) ---
I can confirm the bug is gone now on all my affected systems.

Kernels 6.1.x build & boot fine with GCC 12.2.1 and CLANG 15.0.7, no graphical
corruption or dmesg errors to be seen.

Closing here.
