This bug was about radeonsi, not about Vulkan drivers.

Guys please keep in mind that GPUs are programmable processors.

So when an application sends an shader with an infinity loop to the driver
there is absolutely nothing the driver Mesa stack can do about that.

As Jozef correctly pointed out the best thing we can do is resetting the GPU
after a timeout, but that is really complex and doesn't work all the time.

Anyway closing this bug since the original issue is fixed.

Guess it make sense. 
A thread per "actual issue to fix". 

Even though, it should take nothing to just change component from mesa to DRI

If you want to make this bug about unreliable/unimplemented GPU resets in
amdgpu.ko, then it is filed against the wrong component. AFAIK there is nothing
to fix in Mesa. Other than that, the bug is full of comments about the source
of GPU hang. It may be better to file a new bug for implementing/fixing GPU
resets in amdgpu.

Nice to hear the bug is fixed in wine, but the mesa bug still exists, so the
resolution is wrong. It's simply not acceptable for a driver to freeze the
system if an application misbehaves.

Wine's role should just be that of avoiding their.. stuff, to misbehave. 

But as for the freeze itself, I'd be expecting a bug in amdgpu, if the user
level bug was *allowed* to escalate to kernel one.

Thanks for confirming that the hack actually works.

Yeah, it would be better to not hang in such situation but that's complicated.
Though, you can try to boot with amdgpu.lockup_timeout=3000 (ie. wait 3s) to
recover the state when a lockup is detected, it might work.

I can confirm that it works fine here after applying the hack, too.

Anyway, I'm with Shmerl here. In my opinion a user process should never be able
to make system unusable no matter what kind of stupid stuff it does. I'm fine
with the application crashing or behaving incorrectly - it's that applications
fault after all. Just don't take the system with it.

Also, great work, thank you!

While Wine does something incorrect here, shouldn't amdgpu/radeonsi still
handle such kind of issues more gracefully? I.e. while Wine should be fixed, I
think Mesa shouldn't cause a system freeze when that happens. Can your patch
approach be generally useful for Mesa to make it more resilient, or some other
solution would be needed?

Great! I can confirm, this patch helps both full staging, and regular + minimal
patches Wine. Thanks! I'll point Wine developers to this.

See the attached trace from
https://bugs.freedesktop.org/show_bug.cgi?id=102797, it reproduces the same
issue.

So, basically the issue is that wine fails to set the transform feedback
varyings in some situations, this explains why the following message is
reported "fixme:d3d_shader:shader_glsl_generate_transform_feedback_varyings
Unsupported component range 2-2.". Then, the GPU will hang later on because it
will read garbage from a TFB buffer.

About TW3, I think that game uses TFB in some scenarios, I don't know why and
when, maybe it's based on some occlusion queries or some time constraints?
Either way, this might explain why TFB is not used when tracing with apitrace
or when using "GALLIUM_DDEBUG=800" which will flush and wait 800ms after every
draw call.

The attached patches should workaround both issues (TW3 and Superposition), but
wine has to be fixed here.

Please, let the bug open until it's really fixed.

Ah, I'm not using full staging, but regular Wine (relatively recent master
build) with minimal patchsets required to run the game (as described here:
https://appdb.winehq.org/objectManager.php?sClass=version=34698#notes ).

Let me try it with full staging 2.17.

I applied your hack patch, and here is the output I got (with my other settings
active):

ATTENTION: default value of option mesa_glthread overridden by environment.
*** The Witcher 3 SPECIAL HACK ENABLED ***
Aborted! TFB varyings not correctly set!

The game indeed aborts, rather than hangs there.

special varying hack

Guys, can you apply the proposed special hacky patch and try to reproduce the
hang? It should, at least, partially "fix" the issue in the Velen area (cf the
savegame file).

To be sure the hack is enabled, please redirect stderr (wine witcher3.exe &>
log) and look for "*** The Witcher 3 SPECIAL HACK ENABLED ***".

If the game exits with "Aborted! TFB varyings not correctly set!", there is
something else, but I wouldn't be surprised as the patch is a huge hack just
used to demonstrate the issue. Please report anyways. Thanks!

For a test, I tried doing

sudo cat /sys/kernel/debug/dri/1/amdgpu_gpu_reset

during normal desktop operation (in this setup it's card 1), and it just messes
up KDE / sddm and even restarting sddm it isn't enough after that (soft reboot
was enough).

Then I tested it after the The Witcher 3 freeze above (remotely, over ssh).
That caused complete hang, that even ssh stopped working. So that required hard
reboot.

[Bug 101731] System freeze with AMDGPU when playing The Witcher 3 (GOG GOTY)

You can force a reset by reading /sys/kernel/debug/dri/0/amdgpu_gpu_reset but
very few if any applications currently use the GL robustness extensions to
query if the context is lost and resubmit their state.

I don't have it either for RX 480 card.

There's no such file on my system. There is a reset file for other PCI busses,
but not for the GPU.

How exactly, by writing 1 there?

you can try reseting the GPU manually via 
/sys/class/drm/cardX/device/reset

Yes, I observed that as well. You can access the box over ssh, but it doens't
react to any local input. Also attempts to reboot it remotely hang (systemctl
reboot). And lack of any sensible info in the logs is just strange.

I'm having the same problem during the initial cutscene in Velen.

Here are some additional information:

* While the computer seems frozen, it's not frozen completely. I can still
connect over ssh and do stuff there as if nothing happened. Other services work
uninterrupted, too.

* Locally, only SysRq helps. Even after killing everything using Alt+SysRq+i
the computer doesn't react to anything apart from more SysRq shortcuts.

* dmesg doesn't contain anything useful

* Xorg.0.log doesn't contain anything useful either (on the wine bug there is a
mention about input devices being removed, but that doesn't appear here unless
forced using SysRq).

Happens with AMD RX 480 with mesa 17.2.0 and linux kernel 4.13.2
