Using the drm_fixed calls, this needs to be changed. Which in fact is
more correct, colour.YCbCr_to_RGB() gives 0x8080 for same the yuv
parameters.

With the new 32.32 values it makes more sense to use drm_fixed functions
than trying to recreate the wheel.

Hi,
I just found that the IGT's test kms_writeback has a flag '--dump' that
does that, maybe you can use it or copy the logic to the benchmark.

This benchmark was suggested by Pekka Paalanen on [1] to better analyse
possible performance regression on the Virtual Kernel Modesetting(VKMS)
driver.
With this benchmark I was able to determine two performance regression:

I got pretty interesting results:
The mentioned commit 8356b97906503a02125c8d03c9b88a61ea46a05a took
around 13 seconds. While drm-misc/drm-misc-next took 36 seconds.

Hi,
Please Cc me on the next versions,
You added the argument 'y' to the function but did not change the calls
to it, resulting in a compiler error. I think this argument addition
would be better on patch #2.

I think you meant that is _not_ working. Yeah, as I already explained,
it was never my plan to add support for packed or tiled formats.

The kunit_action_platform_driver_unregister is added with
_platform_driver as ctx, but the kunit_release_action is called
pdev as ctx. Fix that by replacing it with _platform_driver.

d
that.
Patches #2 and #3 solve the use-after-free bug. This error was a bit
trickier to find. Basically, the usual order in which the kunit_actions
run is the culprit, so #2 creates a helper function to reorder actions,
and #3 uses that helper.
