Description Kenneth Graunke 2014-08-11 00:04:05 UTC
On Broadwell, running: $ PIGLIT_PLATFORM=gbm shader_runner tests/spec/glsl-1.50/execution/geometry/max-input-components.shader_test -auto appears to cause GPU hangs, but only some of the time. Other times, it passes. The error state has IPEHR at a PIPE_CONTROL, and the CS (command streamer) and GS are busy. Probably a hang while running the geometry shader.

Is this still an issue? I just ran the test for 10k iterations with no issue.

Seems to work these days - closing. I'm guessing I was getting bit by the "GS Number of URB Entries must be less than or equal to the GS Maximum Number of Threads" workaround that I never implemented, which isn't necessary on production hardware. Either that or we just fixed something.
