Ok, now video playback results in a hangup without a steam client if vaapi is
used:

We are working on the GPU reset, we just don't have any ETA. The GPU reset is
something you can't rely on to save you. In most cases, a successful GPU reset
needs a complete restart of X or Wayland, so you'll lose the whole desktop and
all running desktop applications. You are likely to get into an infinite
GPU-hang+GPU-reset loop if the driver doesn't kill all apps. With the current
Linux desktop architecture that isn't aware of GPU resets, a GPU reset is
mostly unusable.

The implementation of the GPU reset is secondary to making sure that GPU hangs
don't occur. Thus, bugs about GPU hangs are only about fixing GPU hangs. Rise
Of The Tomb Raider is a Vulkan game, so any hangs within the game are RADV
bugs. Filing a bug against DRM/AMDgpu for a GPU hang within that game is less
effective  than filing a bug against RADV.

My bug report about the game Rise of Tomb Raider unfortunately closed without
explanations which patches needed for fix hung:
https://bugs.freedesktop.org/show_bug.cgi?id=106196
And symptomes of problem same as in this bug report:
- The system stop to respod.
- All the LEDs on the video card showing power consumption start to glow.
- The turbine on the video card starts to make a lot of noise.

Long time ago the Intel driver hungs too:
https://bugs.freedesktop.org/show_bug.cgi?id=54226
but intel developers add GPU reset in such situations why not add GPU reset
also for AMD GPU?

Rise of Tomb Raider is a Vulkan game. You can file a RADV bug for it. I'm
closing this since you are not reporting any issues with Youtube.

Looks like my si_pipe.c already patched.
But my GPU still hangs when I try pass one and the same place in the game Rise
of Tomb Rider.

For which mesa version this patch?

My si_pipe.c (mesa 18.0.1) looks differently

I run into this issue regularly with an AMD Ryzen 5 2400G (primary display,
connected via DP to the monitor) and an AMD Radeon RX 560 (not connected to a
monitor, secondary display according to mainboard firmware configuration).

After using my computer for some time, the graphics suddenly freezes and I see
lines like the following in dmesg (after logging in via SSH):

Anybody is investigated this bug?
It is not necessary watch video for occurring computer hung.
It hangs just after running the client's Steam or during the game if computer
already worked some time.
I'm already tired of pressing the reset button because "init 6" is not able to
restart the computer after such a hang.
For today I already press reset button more than 30 times.
But no one care about it :(

I am sorry for misunderstanding.
Every time when I see new commits in branch I hope that this issue may be
fixed.
And every time I rebuild kernel for testing.
And after it I every time I reproduce this annoying bug.
And I still hope that anybody works on it and improve logging for understanding
root cause of this hung.
So I every time attach new dmesg log.

Please stop attaching more and more dmesg with unrelated information to the bug
report. The initial one is perfectly sufficient.

Christian and Alex,

when you do this (rebase to RCx with enabled KPTI patch) please do it at least
to RC7 (NOT penalize AMD chips) even that I'm on Intel Xeon currently...;-)

Can you also rebase amd-staging-drm-next to RC5 with enabled KPTI patch? I do
not want to sit on a vulnerable kernel. The default shipped kernel in Fedora
already patched but not having AMD Vega support.

Earlier kernels don't support GPU Vega. So I can't recheck it with earlier
kernel which works fine with IGPU on same machine.

Does "it occurs on latest staging kernel" mean it doesn't happen with an
earlier staging kernel or with another kernel version? If so, can you provide
more details about what kernels it doesn't happen with?
