[igt-dev] [PATCH i-g-t] tests/kms_plane_lowres: Test only with one plane

[igt-dev] [PATCH i-g-t] tests/kms_plane_lowres: Test only with one plane

[Mika Kahola]

The test is intended to test resolution changes from higher to
lower and back. We can test this with only one plane and we don't
need to run through all planes. This will save significant amount
of test execution time.

I'm having a hard time understanding how this change fixes this issue.

At this point one must ask: Why have the count variable anymore?

For some reason crc's don't match if we loop through multiple overlay
planes. The reference image has primary, first overlay and cursors
plane. Crc already fails if we compare the reference with the image
having primary, second overlay and cursor plane. This I have been
testing with TGL.

Commit message talks about saving test execution time but this
explanation is about working around failures.

What is actually broken and is this working around an issue or hiding
it? Is it always the same plane combination failing, every test round?

(Am I reading the test wrong though, as far as I can see there's just
two planes in use at a time, primary and one other...)

At the very least one plane of each type should be tested instead of
just the first non-primary.

Right. I should have been more verbal about the commit message. On TGL
running a single subtest takes ~15s with one plane of each type. If we
loop through all planes, it takes ~55s.

That's true. The crc's are ok with overlay plane[0] but has a mismatch
on the round plane[1]. Should we draw references too with all the
overlay planes instead? Any suggestions how to handle this?

Originally, we tested only with the first overlay plane. This is not
about testing the plane but more on testing resolution changes. That's
why I suggested to take a step back and test only with one plane.

The thumb rule is that we have a test case for all different
behaviours of the driver, and incidentally for different behaviours of
the hardware because the kernel is supposed to handle the
differences. I suppose the pertinent question here is: Does the driver
have different code paths for resolution changes for different plane
usage?

I would expect that using any subset of HDR planes (first three
planes) + cursor to produce the same crc. The crc could be different
if any SDR planes are used since we have to instruct the hw to go
through the non-HDR blending path. If the test already fails with
some HDR planes then feels like there is an actual problem somewhere.

Maybe we could run a test which takes reference for each and every
plane separately and check how crc's compare with that. It would be
quickly checked and verified.
