<pre>If I run piglit inside QEMU with virgl, I get an assert inside the i965 driver
like so:
../src/intel/compiler/brw_fs_visitor.cpp:449: void
fs_visitor::emit_fb_writes(): Assertion `!prog_data->dual_src_blend ||
key->nr_color_regions == 1' failed.
To avoid running the complete test-suite, you can run this to reproduce it
instead:
piglit run quick_gl -t
".*arb_blend_func_extended-fbo-extended-blend-pattern_gles2" results/quick_gl/
What you'll see is the whole VM crashing, due to the VM process calling
abort().
This obviously requires an assert-enabled build of mesa to reproduce.
It also seems I'm not the only one who has this problem:
