According to JP might be test issue, could someone confirm?

> According to JP might be test issue, could someone confirm?

I was briefly looking at this test and notice it is written against old IGT, lot of things are done differently nowadays. I was just earlier pointing out for Jani that IGT has evolved quite much in four years.

Though, if this test suddenly started to fail virtually on every gen>9 platform on 2018-10-09 maybe there is around those days kernel commit which touch something SKL_* that is responsible?

HI, That is Juha reversed, ahuj.
Comment 11 Lakshmi 2019-04-25 13:19:04 UTC
Bumping the priority to high as we the issue on shards as well.
Comment 12 Swati Sharma 2019-04-26 12:12:54 UTC
Ville's patch https://patchwork.freedesktop.org/series/59419/ fixing this issue. Tested on ICL.

This series was merged, 

drm/i915: Enable pipe HDR mode on ICL if only HDR planes are used
did this fix issue?

Tested with kernel 5.1.0-rc7+ having Ville's fix, kms_flip_tiling all sub-tests are passing.
Comment 15 Jani Saarinen 2019-05-07 12:54:53 UTC
So, can we remove ICL from list of platforms?

ON ICL, on an average this failure occurs once in 4.4 drmtip runs. Last seen on drmtip_271, so we can remove ICL after drmtip_315 if no new failures are seen on ICL.
Comment 17 Jani Saarinen 2019-05-08 06:34:22 UTC
Lowering priority ok?
Comment 18 Lakshmi 2019-05-13 15:02:07 UTC

> Lowering priority ok?
Still occurring on ICL
