Hi Vidya,
on which machines this would help? I see there's many vblanks already
being waited. There's igt_display_commit2 which probably will block and
even if it didn't there's igt_pipe_crc_collect_crc(..) where crc
calculation is started after flip and then get one crc before disabling
crc
Without wait for vblank, CRC mismatch is seen
between big and small CRC on few systems
