Bug ID: 84836
Summary: VERDE lockup with Unigine Valley/Heaven if
ARB_sample_shading is enabled
Product: Mesa
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: alexander@tsoy.me
Created attachment 107614
--> https://bugs.freedesktop.org/attachment.cgi?id=107614&action=edit
dmesg output
Unigine Valley 1.0 and Heaven 4.0 cause VERDE GPU lockup when
ARB_sample_shading is enabled. With kernel 3.14.19 I got immediate lockup.
3.14.20 allows Valley and Heaven to run for up to 1 min. GPU fails to resume
after lockup, screen becomes corrupted and I need to reboot the system.
If I disable ARB_sample_shading (via env variable
MESA_EXTENSION_OVERRIDE=-GL_ARB_sample_shading) then VERDE GPU do not hang at
all (currently valley is running on my system for more than two hours without
lockups).
I also have BONAIRE GPU and it does not hang.
Software versions:
kernel-3.14.20
mesa-10.3.0
llvm-3.5
xf86-video-ati 7.4.0
libdrm-2.4.56

Seems to work fine on my Cape Verde. What brand and model do you have
specifically?
Can you try a newer kernel?

Gigabyte GV-R775OC-2GI. And if that matters, it's a revision with Micron
memory, flashed with latest available BIOS version F3.

I'll try 3.16 and 3.17 kernels next week.

I think you forgot to install drirc from Mesa. What happens if you set this env
var?
allow_glsl_extension_directive_midshader=true

No, I have correct drirc.

Setting this env variable doesn't help.

I just tried 3.17.0:
- GPU still hangs if ARB_sample_shading is not disabled.
- It seems lockup detection timeout was increased significantly:
kernel: radeon 0000:01:00.0: ring 0 stalled for more than 91985msec
kernel: radeon 0000:01:00.0: GPU lockup (waiting for 0x000000000000e90a last
fence id 0x000000000000e8fb on ring 0)
- Unrelated to this bug, but.. animation is VERY choppy. I constantly see
several-seconds-long freezes, and sometimes >10 sec long freezes.

Should be better with current Mesa Git master, see bug 84662.

Not sure what fixed this, but there is no GPU hang anymore. I also disabled the
drirc workaround, so that Heaven would fail to compile its shaders. Tested on
my VERDE.

JFYI: This card was unstable when operating at 850Mhz sclk (same problem on
Windows). After flashing VBIOS from GV-R775D3-2GI (same card physically, but
with 800MHz sclk) it works fine now. So this looks like a faulty vendor
overclock.
