As we do for NV12, let's also clear packed YUV formats to black instead
of zero. Avoids unexpected green screens.

v2: Nuke the debug messages

We don't do the "black != zero" clearing for dumb buffers, so let's not
use them for YCbCr framebuffers.

v2: Use igt_format_is_yuv()

I fear this will not allow us to support !i915, we should start caring at some point and either move to minigbm or roll special cases for each driver..

But for now it's ok.

Always populate the plane_bpp[] stuff, and use named initializers so
that we can actually see what's being set to what.

Probably horribly inefficient (not that the original code tried to be
particularly efficient), but at least this is now pretty generic so
it'll be super easy to add other color encodings and whatnot.

v2: Rebase
v3: Deal with the new color_encoding/range enums
v4: Fix the code to actually work, and do things in 2x2 blocks
    Keep the chroma siting comment and pimp it up a bit

Hey,

Conversion routines taken out (0s converting):
real    0m22,732s

Unpatched kms_nv12 run:
real    0m27,044s (4.3s converting)

Patched kms_nv12 run:
real    0m37,778s (15s converting)

It's not just making things worse, it's making it 3.5x slower. :/

We could get rid of the height & 1 and width & 1 checks, we only allow an alignment with a multiple of 4 in i915, and I think restricting it to 2x2 in igt won't lose us much...

One thing we should definitely do is making igt_matrix_transform inline, and enable vectorization somehow. The current code is horribly unoptimized. :(

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Reuse the __convert() cairo stuff to support packed YCbCr framebuffers.

v2: Allow odd fb width since some tests want it
v3: Use igt_memcpy_from_wc()
v4: Rebase due to color_encoding/range enums
v5: Follow the fixed nv12 code
v6: Use igt_format_is_yuv()

Make igt_fb be aware of the color encoding/range. For now
we still hardcore everything to BT.709 limited range though.

v2: Default to BT.709

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Insted of just trying out each pixel format once, let's try each one
with a set of colors (RGB,CMY,white,black). We'll grab a reference CRC
for each using XRGB8888, and then compare that with the CRC we get
with any other format.

We have to use a solid color fb because chroma subsampling would
generally prevent us from getting a match if we had any color
transitions in the fb contents.

We also abuse the legacy LUT to drop the precision down to 7 bits
so that still errors causes by the RGB<->YCbCr conversion end up
being ignored.

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Insted of just trying out each pixel format once, let's try each one
with a set of colors (RGB,CMY,white,black). We'll grab a reference CRC
for each using XRGB8888, and then compare that with the CRC we get
with any other format.

We have to use a solid color fb because chroma subsampling would
generally prevent us from getting a match if we had any color
transitions in the fb contents.

We also abuse the legacy LUT to drop the precision down to 7 bits
so that still errors causes by the RGB<->YCbCr conversion end up
being ignored.

v2: don't set Broadcast RGB prop if it's not there

Broadcast RGB is always set to full why are you touching this?

With wmemset in patch 1, and broadcast rgb calls removed on thi sseries:
