Bug ID: 110637
Summary: Enabling OpenCL in Libreoffice kills Vega 64
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW

Reporter: mezin.alexander@gmail.com
Created attachment 144191

kernel log
Open LibreOffice, enable OpenCL in settings, restart it.

And the same thing with 4.19.40. And with manually built drm-next.
Also, not only libreoffice, but literally any application that uses OpenCL
triggers the same problem. It seems that I just can't use OpenCL at all.

More likely a bug in the mesa OpenCL code. If you want functional OpenCL, you
should use the ROCm OpenCL packages.

I thought that buggy userspace shouldn't cause a complete GPU lockup like
this...
The kernel log says "GPU reset succeeded", but it leaves GNOME session
completely unusable (hung, artifacts on screen), restarting GDM also fails, the
only way to recover is rebooting (sometimes only through Sysrq)
And also I get a very similar lockup (the same messages in kernel log, again
with all kernel/firmware versions I tried) in a few Steam games running on
Proton/DXVK.
Will try different mesa versions

--- Comment #6 from Jan Vesely <jv356@scarletmail.rutgers.edu> ---
Can you post the output of 'clinfo'?
GPU hangs in clover are usually signs of old LLVM, or old mesa (that does not
catch function calls).
Do you use ocl-icd?
if yes can you confirm if the games hang when running with
OCL_ICD_VENDORS=/var/empty/ ?
(alternatively, you can just move libMesaOpenCL.* out of library path)
(In reply to Alex Deucher from comment #3)
> More likely a bug in the mesa OpenCL code. If you want functional OpenCL,

I doubt that. clover uses the same LLVM code generation paths.
also note: "the same problem with multiple games", I doubt those use OpenCL.
the above steps should confirm that.
My guess is that compute shaders are busted (irrespective of the API).
GPU reset has never worked correctly on any AMD GPU that I've ever used.

No, setting OCL_ICD_VENDORS didn't change anything (though I'm not completely
sure that Steam and then Proton don't discard environment variables somewhere).
However, upgrading Mesa to 19.0.4 fixed game hangs. OpenCL issues are still
here.

Tried Mesa 19.1.0-rc3
Geekbench hangs, but there are no immediate errors in dmesg. It looks like gpu
is doing something based on 'sensors' output (~130 W power consumption, at idle
it is <20W). And power consumption doesn't go down even when I kill geekbench.
When I try to reboot, the system hangs.

Do you mean "Mesa OpenCL is not supported/unmaintained"?
I still can't get any OpenCL application to work (even "Hello World" examples).
Mesa 18.3.4, 19.0.x - GPU hangs then resets. But judging by power consumption
(hwmon, 70W - higher than usual idle power consumption) GPU continues to do
something even after reset
Mesa 19.1.x, git master - GPU doesn't hang but applications themselves hang on
the first clFinish. Power consumption stays higher than typical idle power
again.
Building ROCm from source is a huge pain.
