Not sure what test you're actually after here. This only changes
what we expose in the blobifier, but it doesn't change what kind
modifiers the user can actually use with the sprites. Ie. Y/Yf
tiled framebuffers are accepted even before this patch. I do
believe we have some Y/Yf tests on arbitrary planes in some
of the plane tests.
We have no specific tests for blobifiers I think. kms_ccs does use
them to check for CCS support though. We should probably add something
to igt_kms to use them for figuring out which format+modifier combos
are supported by each plane.
