It happens on all platform with -queued and -fixes kernel. It works well on -nightly kernel. commit bd008e5b2953186fc0c6633a885ade95e7043800 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Oct 7 14:13:51 2014 +0100 drm: Implement O_NONBLOCK support on /dev/dri/cardN is not yet in dinq The test should be unblocked by commit f6aa80c (tests/kms_flip: add a timeout for the nonblocking-read test) in intel-gpu-tools. This causes the test to exit with timeout status for kernel builds without the commit mentioned in comment #2. Verified on latest igt(d8078911f63494eba67f8f07ffb56c4bdeae7bc9). ./kms_flip --run-subtest nonblocking-read IGT-Version: 1.8-gd807891 (x86_64) (Linux: 3.18.0-rc5_drm-intel-nightly_0f8cb1_20141123_debug+ x86_64) Using monotonic timestamps Subtest nonblocking-read: SUCCESS (0.000s) Closing old verified. |
