Hei
Sorry I had missed original patch set hence slow to comment, now my mail
client picked up my name here. Generally things look all ok to me with
just one exception, I wish things going to lib/ will be separated into
their own patch from things going into actual test in tests/ so later
when will see changes in test there will not come changes in view not in
test itself.
For those amd related changes I cannot say anything because I don't have
amd hw to try with. I'll put some comments below that just come to my mind.

I'm ok with this change but I was wondering why is this so for amd?
Driver on amd has crc counted all the time or crc buffer is very short?
On intel hw restarting crc counting will waste several vblanks which can
overall double execution time of this test.
If crc buffer is very short on amd there is also possibility to use
igt_pipe_crc_drain(..) placed 'correctly'

I think this will cause you will get only DRM_FORMAT_XRGB8888 tested on
amd and also if there's cursor plane tested it will go with
DRM_FORMAT_XRGB8888.
