The problem with piglit is that it runs every single subtest as a
separate test program invocation. For KMS tests this is a huge problem
since it requires generating the reference CRCs every time and it also
requires a modeset to restore fbcon every single time. For non-eDP the
cost is not big, but for eDP it adds up: running a subset of only 70
subtests on kms_frontbuffer_tracking, we go from 3:05 to 6:21 in total
execution time.
