Maybe we are missing a vblank wait somewhere on kernel CRC code?! Or maybe o kernel we read and discard the first for GLK?! :/ Also this is pipe crc right?! Shouldn't it be independent of the panel at the end?! Does it only happen with MIPI/DSI ?! Or it just happen on that particular unity on CI

It seems that at least with GLK with MIPI/DSI display, the first collected CRC is bogus. To fix this, try to collect two CRC's instead of one. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101309 Signed-off-by: Mika Kahola --- tests/kms_frontbuffer_tracking.c |
