i915 error output
Hi,
I added the output of /sys/class/drm/card0/error
This happens to me on my Dell XPS 13 9360. I'm using kernel 4.12.14 but it also
happens on 4.13.5.
Mesa version is 17.2.2
$ lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 620
[8086:5916] (rev 02)
Journal output looks like this :
Oct 08 17:13:13 richter-xps-13 kernel: [drm] GPU HANG: ecode 9:0:0x85dffffb, in
chromium [5245], reason: Hang on rcs, action: reset
Oct 08 17:13:13 richter-xps-13 kernel: drm/i915: Resetting chip after gpu hang
Oct 08 17:13:13 richter-xps-13 kernel: [drm] RC6 on
Oct 08 17:13:13 richter-xps-13 kernel: [drm] GuC submission enabled (firmware
i915/kbl_guc_ver9_14.bin [version 9.14])
Oct 08 17:13:34 richter-xps-13 kernel: [drm:intel_cpu_fifo_underrun_irq_handler
[i915]] *ERROR* CPU pipe A FIFO underrun
This seems specific to chromium-vaapi, when playing a video everything freezes
while the sound is playing then comes the reset and the video catches up to the
sound by going in fast forward (all missed frames are played back at once it
seems).</pre>
