gpu crash dump
hw platforms:
- Skylake i7 NUC6i7KYK (GPU Iris Pro 580)
- Skylake i5 NUC6i5SYK (GPU Iris Graphics 540)
The problem does not happen with Skylake i3 NUC6i3SYL (GPU Iris HD 520); it
happens both headless and under xorg
libdrm: 2.4.70
Running the following command twice in a row (quickly) results in a GPU reset
(gstreamer master required):
gst-launch-1.0 videotestsrc num-buffers=100 ! video/x-raw\,\
format\=\(string\)I420\,\ width\=\(int\)1920\,\ height\=\(int\)1080\,\
framerate\=\(fraction\)30/1 ! vaapih264enc tune=low-power ! fakesink
silent=false -v

[ 613.290989] [drm] GPU HANG: ecode 9:3:0xcb79ffc4, in videotestsrc0:s [2622],
reason: Engine(s) hung, action: reset
[ 613.290992] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 613.290995] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 613.290997] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 613.290999] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
