[v2 0/2] Enable Plane Input CSC for ICL

[v2 0/2] Enable Plane Input CSC for ICL

[Uma Shankar]

This patch series enables plane input csc feature for
ICL. This is needed for YUV to RGB conversion on bottom
3 planes on ICL, other planes are handled in the legacy
way using fixed function hardware.

v2: Separated the patch into 2 parts as per Maarten's comments.
Addressed Ville and Maarten's review comment.

[v2 1/2] drm/i915/icl: Define Plane Input CSC Coefficient Registers

[Uma Shankar]

Defined the plane input csc coefficient registers and macros.
6 registers are used to program a total of 9 coefficients,
added macros to define each of them for all the planes
supporting the feature on pipes. On ICL, bottom 3 planes
have this capability.

v2: Segregated the register macro definition as separate patch
as per Maarten's suggestion.

Is the "Pre-ICL" comment here a copy/paste error?  The other registers
marked that way say "This field is deprecated" in the bspec, but that
isn't the case for the input CSC.

I don't think we usually add the third address to i915_reg.h when
planes/pipes are equally spaced since our macros can calculate all the
subsequent offsets automatically.  Same also applied to other regs
farther down.

Since these are really just the next dword of the same logical register
as above, maybe it would be simpler to just define these (and the other
dwords of PLANE_INPUT_CSC_COEFF below) as _RY_GY + offset?

Yes, this should be ICL+. I will update that. Thanks

Yes, there are some PLANE MACROS defined using 3rd plane, but it's really not
required, Will drop the same.

Yes, this can be done. Will modify these macros. 

Thanks Matt for the review comments. Will address and refloat the series.

[v2 2/2] drm/i915/icl: Enable Plane Input CSC for YUV to RGB Conversion

[Uma Shankar]

Plane input CSC needs to be enabled to convert frambuffers from
YUV to RGB. This is needed for bottom 3 planes on ICL, rest of
the planes have hardcoded conversion and taken care by the legacy
code.

This patch defines the co-efficient values for YUV to RGB conversion
in BT709 and BT601 formats. It programs the coefficients and enables
the plane input csc unit in hardware.

Note: This is currently untested and floated to get an early feedback
on the design and implementation for this feature. In parallel,
I will test this on actual ICL hardware and confirm with planar
formats.

v2: Addressed Maarten's and Ville's review comments and added the
coefficients in a 2D array instead of independent Macros.

Just to confirm, we're specifically talking YUV444(packed) -> RGB here,
right?  So for formats like NV12 (YUV 420), the chroma upsampler first
merges/scales the Y and UV planes to produce YUV444(packed) data which
then has this input CSC matrix applied to convert it to RGB?  And then
after that point there's a separate set of userspace-programmable
degamma/CSC/gamma set of steps, which is what your other series "[RFC v5
0/8] Add Plane Color Properties" adds, right?  And then after that comes
the pipe-level degamma/CSC/gamma...

Is there somewhere in the bspec that talks about this input CSC in more
detail?  I don't see any mention on the general YUV programming or plane
capability pages, and the register details themselves are pretty sparse,
so it's hard to fully review these for correctness.  Based on your code
here, it appears the INPUT_CSC follows the same general layout and
expected coefficient values as the pipe CSC, but I'm not sure where in
the spec to confirm that.

This is correct, all the planar formats first should be upsampled to YUV444 and then
the general  YUV->RGB conversion will happen using the Plane Input CSC hardware block.
Once this conversion is done, later the other plane CSC hardware (after de-gamma) can be
used to convert the colorspace if required (SRGB to BT2020 etc).

Unfortunately not much details are available in bspec, this is based on my understanding
of the hardware pipeline taking reference from few DCN document for HDR. But, in
general what you said is correct and this is how input csc hardware block is supposed to work.
Though it's a multipurpose programmable unit, but YUV444->RGB conversion is its primary
usecase in a real world scenario.

Maybe each component separately? uint16 [][9]

Also BY/BU/BV are programmed in bits 31-16 according to bspec. :)
Seems that bug was already there in the original submission?

Otherwise looking much better!

And once more, I still miss any form of limited/full range handling?

Sure, I will do that.

Yes, thanks for spotting this. Will correct it.

My plan is to add limited range and other colorspace in a later patch since
we need to calculate the exact coefficients for those cases. If its ok, I can
re-submit the next version just limiting to full range as of now.
