Afaik, we ignore kms_plane_lowres since most tests look related to
tiling-[x|y], which I think is an Intel modifier (again, maybe I'm
wrong). Anyway, I tried to run it on an AMD device, and most
kms_plane_lowres subtest skips.

Mark, Juha-Pekka,
Tbh, right now, I prefer to keep this test as AMD-specific because we
are trying to fully upstream all of our tests, so we can rely on igt
from the upstream. I can create a README file for amdgpu tests and
create a TODO section where I can highlight that we can make this test
and other generic; how about that?
Hi Lakshmi,
This test is specific to AMD, but CI is failing. I think it is another
false-positive. Here is the patch:

Thanks
