Is this a regression or has the testcase always failed (it was renamed from ZZ_missded_irq recently)? (In reply to comment #1) > Is this a regression or has the testcase always failed (it was renamed from > ZZ_missded_irq recently)? I test it on earlier kernel. The return code also is 1(run ZZ_missded_irq). It always fail. Timeout, please retest on latest drm-intel-nightly. commit 5eeb1f34d4bd16ef22e9252e876dd93c28c73b3c Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Sep 6 17:25:01 2014 +0100 igt/drv_missed_irq_hang: Increase busy load The test relies on having to wait upon the GPU at some point and so simulating a missed interrupt. If there is insufficient load on the GPU, we can complete the task before we even wait. References: https://bugs.freedesktop.org/show_bug.cgi?id=71334 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> It works well on latest -nightly kernel. Closing old verified. |
