/sys/class/drm/card1/error from after a hang
Hi,
I'm trying a brand new Coffee Lake (i5-8400). The primary GPU is an NVIDIA
card; the Intel GPU is used for VA-API only. I can post frames for encoding
just fine (I have my own VA-API application), but they seemingly never come
back, and the kernel complains:
[ 621.837356] [drm] GPU HANG: ecode 9:0:0x8fd8ffff, reason: Hang on rcs0,
action: reset
[ 621.837356] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 621.837357] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 621.837357] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 621.837357] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 621.837357] [drm] GPU crash dump saved to /sys/class/drm/card1/error
