Description Marc-Andre Lureau 2016-07-07 11:53:33 UTC

Running virglrenderer: 

vtest/virgl_test_server --no-fork

and 

LIBGL_ALWAYS_SOFTWARE=y GALLIUM_DRIVER=virpipe  /usr/lib64/piglit/bin/shader_runner /usr/lib64/piglit/tests/spec/glsl-1.30/execution/switch/vs-uniform.shader_test -auto

Will lead to this crash:

brw_shader.cpp:1087: void backend_instruction::remove(bblock_t*): Assertion `inst_is_in_block(block, this) || !"Instruction not in block"' failed

Comment 1 Matt Turner 2017-02-24 01:16:13 UTC

I tried to reproduce this, but I think I'm not running something correctly:

LIBGL_DRIVERS_PATH=~/projects/mesa-gallium/lib LD_LIBRARY_PATH=~/projects/mesa-gallium/lib vtest/virgl_test_server --no-fork

mattst88@macbook piglit % LIBGL_DRIVERS_PATH=~/projects/mesa-gallium/lib LD_LIBRARY_PATH=~/projects/mesa-gallium/lib/gallium LIBGL_ALWAYS_SOFTWARE=y GALLIUM_DRIVER=virpipe  bin/shader_runner tests/spec/glsl-1.30/execution/switch/vs-uniform.shader_test -auto
libGL error: core dri extension not found
libGL error: failed to load driver: swrast
GLSL not supported.
PIGLIT: {"result": "skip" }

Any ideas what's going on? Maybe it's possible to make an apitrace?

Comment 2 Marc-Andre Lureau 2017-02-24 15:31:56 UTC

I never tested virgl on Mac, the vtest server is likely not going to work.

But this no longer crashes, so closing

thanks

Oh, no, I'm on Linux. The hostname is just macbook because I'm uncreative :)

Oh, okay. Thanks, and sorry for not investigating sooner.
