            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

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.
