[igt-dev] [PATCH i-g-t] tests/kms_yuv: Add yuv specific tests, v5.1.

Hi Maarten,

I was wondering these new yuv tests seem to have skipped all machines 
with exception for sanity crc test.

> Add tests excercising switching between various scaled/unscaled

> workarounds mention this may fail.
> 
> We also add NV12 specific clipping/scaling tests, to make sure
> that YUV src coordinates are always programmed as a multiple of 2
> correctly, and verify scaling/clipping works with CRC tests.
> 
> crop-scale-bug shows a corruption when scaling and cropping at the
> same time.
> 
> The subpixel clip test rotates and clips a rectangle on each side,
> which should produce the same CRC as when that part of the rectangle
> is hidden by a cursor and a whole 2x2 pixel is hidden.
> 
> Changes since v1:
> - Reset plane position to 0,0 at the start of yuv_valid_width_plane().
> - Handle Swati's feedback.
> Changes since v2:
> - Skip 90°/270° rotation in tests when formats don't support it.
> - Add all new HDR formats to test.
> - Use igt_plane_has_format_mod.
> - Support tests on !i915 by checking if X/Y tiling modifiers are supported.
> - Do not enable untested planes to prevent exhausing memory bandwidth
>    and available NV12 Y planes in the rgb-switch-scaled test.
> Changes since v3:
> - Add a sanity test to sanity test YUV conversion paths, on all planes and pipes.
> - Dynamically generate list of YUV tests through igt_format_array_fill.
> Changes since v4:
> - Decrease size to 64x64 to reduce test execution time even more,
>    some YUV conversion routines are slow.
> - Don't clear degamma/ctm, this is done in core now.
> Changes since v5:
> - Fix minor compile error.
