[Intel-gfx] [PATCH igt] igt/kms_frontbuffer_tracking: Drop unsynchronized pageflip test

2016-11-10 Thread Chris Wilson
A raw pageflip is nonblocking and asynchronous, but kms_frontbuffer_tracking persumed that it was synchronous and completed before the funtion returns. It doesn't, so the CRC could be sampled before the flip completed. Signed-off-by: Chris Wilson --- tests/kms_frontbuffer_tracking.c | 8
