Not seen on ICL lately?
Last seen in https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_117/fi-icl-u/igt@kms_plane@pixel-format-pipe-a-planes.html, after being seen every single drmtip run after drmtip_95 (introduction of ICL).
I guess this is sufficient to say that ICL is fixed.(In reply to Mika Kahola from comment 6)
If this error is not seen regularly, maybe we could pump up a bit the size
of a ringbuffer. Now, we have DRM_CRC_ENTRIES_NR defined as 128, so maybe we
could increase it to 256?
Are the CRCs per pipe or global? If it is per-pipe, then 128 CRCs @ 60 Hz is more than 2 seconds of not reading the crc... I would think that this ought to be sufficient and if it is not, we really need to look into why we have such latency in the userspace, don't you think? :omentioned in issue #15 (closed)
