[Mikhail Gavrilov]

Hi,
Between commits ed4643521e6a and 34af78c4e616 something was broken.
I noted that kernel log flooded with warning message "WARNING: CPU: 31
PID: 51848 at drivers/dma-buf/dma-fence-array.c:191
dma_fence_array_create+0x101/0x120" when some games are running:
"Resident Evil Village", "Marvel's Avengers", "The Dark Pictures
Anthology: House of Ashes".

Re: [Bug][5.18-rc0] Between commits ed4643521e6a and 34af78c4e616, appears warning "WARNING: CPU: 31 PID: 51848 at drivers/dma-buf/dma-fence-array.c:191 dma_fence_array_create+0x101/0x120" and some games stopped working.

[Christian König]

Hi Mikhail,

those are two independent and already known problems.

The warning triggered from the sync_file is already fixed in 
drm-misc-next-fixes, but so far I couldn't figure out why the games 
suddenly doesn't work any more.

There is a bug report for that, but bisecting the changes didn't yielded 
anything valuable so far.

So if you can come up with something that would be rather valuable.

Regards,
Christian.

It’d be great, if you (or somebody else) could provide the URL to that

I found how to fix my build problems. They are all related to gcc12.
And making again git bisect and found which commit lead to stuck the
games "Forza Horizon 5", "Forza Horizon 4", "Cyberpunk 2077".
At least it affected hardware Radeon 6900 XT, Radeon 6800M and Radeon VII.

drm/amdgpu: remove ctx->lock

    drm/amdgpu: remove ctx->lock

    KMD reports a warning on holding a lock from drm_syncobj_find_fence,
    when running amdgpu_test case “syncobj timeline test”.

    ctx->lock was designed to prevent concurrent "amdgpu_ctx_wait_prev_fence"
    calls and avoid dead reservation lock from GPU reset. since no reservation
    lock is held in latest GPU reset any more, ctx->lock can be simply removed
    and concurrent "amdgpu_ctx_wait_prev_fence" call also can be prevented by
    PD root bo reservation lock.

    call stacks:
    =================
    //hold lock
    amdgpu_cs_ioctl->amdgpu_cs_parser_init->mutex_lock(&parser->ctx->lock);
    …
    //report warning
    amdgpu_cs_dependencies->amdgpu_cs_process_syncobj_timeline_in_dep \
    ->amdgpu_syncobj_lookup_and_add_to_sync -> drm_syncobj_find_fence \
    -> lockdep_assert_none_held_once
    …
    amdgpu_cs_ioctl->amdgpu_cs_parser_fini->mutex_unlock(&parser->ctx->lock);

After reverting commits 57230f0ce6eda6d47a2029b7b3a39cc5bb63fe32,
461fa7b0ac565ef25c1da0ced31005dd437883a7 the games "Forza Horizon 5",
"Forza Horizon 4", "Cyberpunk 2077" start working again.
Removing commit 57230f0ce6eda6d47a2029b7b3a39cc5bb63fe32 isn't really
needed. I made it because I didn't want to resolve conflicts.

I own you a beer.

I still don't know what happens here, but that makes at least a bit more 
sense than a patch which only changes comments :)

Looks like we are missing something here. Can I send you a patch to try 
something later today?

Thanks,
Christian.

Please test the attached patch, it just re-introduce the lock without 
doing much else.

And does your branch contain the following patch:

The all listed games are now working with an attached patch.
Also flood messages "WARNING: CPU: 31 PID: 51848 at
drivers/dma-buf/dma-fence-array.c:191
dma_fence_array_create+0x101/0x120" has gone.

That's unfortunately not the end of the story.

This is fixing your problem, but reintroducing the original problem that 
we call the syncobj with a lock held which can crash badly as well.

Going to take a closer look on Monday. I hope you can test a few more 
patches to help narrow down what's actually going wrong here.

Thanks,
Christian.

No, I just couldn't find time during all that bug fixing :)

Sorry for the delay, going to take a look after the eastern holiday here.

The message is just for history. The issue was fixed between

We have implemented a workaround, but still don't know the exact root cause.

If anybody wants to look into this it would be rather helpful to be able 
to reproduce the issue.

Christian.

I see that issue was returned after this commit
dd80d9c8eecac8c516da5b240d01a35660ba6cb6 is the first bad commit
commit dd80d9c8eecac8c516da5b240d01a35660ba6cb6

    drm/amdgpu: revert "partial revert "remove ctx->lock" v2"

    This reverts commit 94f4c4965e5513ba624488f4b601d6b385635aec.

    We found that the bo_list is missing a protection for its list entries.
    Since that is fixed now this workaround can be removed again.
