* [PATCH] drm/core: Fail atomic IOCTL with no CRTC state but with signaling. @ 2017-06-09 21:30 ` Andrey Grodzovsky 0 siblings, 0 replies; 28+ messages in thread From: Andrey Grodzovsky @ 2017-06-09 21:30 UTC (permalink / raw) To: dri-devel, linux-kernel, intel-gfx, maarten.lankhorst Cc: amd-gfx, harry.wentland, Andrey Grodzovsky Problem: While running IGT kms_atomic_transition test suite i encountered a hang in drmHandleEvent immidietly follwoing an atomic_commit. After dumping the atomic state I relized that in this case there was not even one CRTC attached to the state and only disabled planes. This probably due to a commit which hadn't changed any property which would require attaching crtc state. This means drmHandleEvent will never wake up from read since without CRTC in atomic state the event fd will not be singnaled. This point to a bug in IGT but also DRM should gracefully fail such scenario so no hang on user side will happen. Fix: Explicitly fail by failing atomic_commit early in drm_mode_atomic_commit where such problem can be identified.

Sending 0 events is no problem at all on it's own but if user provides DRM_MODE_PAGE_FLIP_EVENT in args then when it becomes a problem , doesn't it mean he expects to receive at least one event ?

We need to fix the testcases, and even better would be to have an explicit testcase which does such a no-op atomic ioctl + event and checks that we get the -EINVAL. Same applies for asking for events when the crtc is off and stays off btw, but I think we catch that already somewhere. But again would be good to make sure we have an igt for it.

* [PATCH v2] drm/core: Fail atomic IOCTL with no CRTC state but with signaling. 2017-06-19 15:35 ` Harry Wentland @ 2017-06-20 17:57 ` Andrey Grodzovsky -1 siblings, 0 replies; 28+ messages in thread From: Andrey Grodzovsky @ 2017-06-20 17:57 UTC (permalink / raw) To: harry.wentland, dri-devel, linux-kernel, intel-gfx, maarten.lankhorst Cc: amd-gfx, seanpaul, daniel, Andrey Grodzovsky Problem : While running IGT kms_atomic_transition test suite i encountered a hang in drmHandleEvent immediately following an atomic_commit. After dumping the atomic state I relized that in this case there was not even one CRTC attached to the state and only disabled planes. This probably due to a commit which hadn't changed any property which would require attaching crtc state. This means drmHandleEvent will never wake up from read since without CRTC in atomic state the event fd will not be signaled. Fix: Protect against this issue by failing atomic_commit early in drm_mode_atomic_commit where such probelm can be identified. v2: Fix typos and extra newlines.
