[PATCH v4 00/10] Clear Color Support for TGL Render Decompression

[Radhakrishna Sripada]

Support for Clear Color is contained in the last two patches
submitted by Radhakrishna Sripada. The first 8 patches are
currently undergoing review/revision changes. The first 8 patches
are cherry-picked from the series
https://patchwork.freedesktop.org/series/67078/

Expecting feedback for the last 2 patches. The series is tested with kms_cube
and custom Mesa branch by Nanley.

[PATCH v4 02/10] drm/i915: Use intel_tile_height() instead of re-implementing

[Radhakrishna Sripada]

From: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com>

intel_tile_dims() computes tile height using size and width, when there
is already a function to do just that - intel_tile_height()

[PATCH v4 04/10] drm/i915/tgl: Gen-12 render decompression

[Radhakrishna Sripada]

From: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com>

Gen-12 display decompression operates on Y-tiled compressed main surface.
The CCS is linear and has 4 bits of metadata for each main surface cache
line pair, a size ratio of 1:256. Gen-12 display decompression is
incompatible with buffers compressed by earlier GPUs, so make use of a new
modifier to identify gen-12 compression. Another notable change is that
render decompression is supported on all planes except cursor and on all
pipes. Start by adding render decompression support for [A,X]BGR888 pixel
formats.

v2: Fix checkpatch warnings (Lucas)
v3:
Rebase, disable color clear, styling changes and modify
intel_tile_width_bytes and intel_tile_height to handle linear CCS

[PATCH v4 05/10] drm/i915: Extract framebufer CCS offset checks into a function

[Radhakrishna Sripada]

From: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com>

intel_fill_fb_info() has grown quite large and wrapping the offset checks
into a separate function makes the loop a bit easier to follow.

[PATCH v4 06/10] drm/framebuffer: Format modifier for Intel Gen-12 media compression

[Radhakrishna Sripada]

From: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com>

Gen-12 display can decompress surfaces compressed by the media engine, add
a new modifier as the driver needs to know the surface was compressed by
the media or render engine.

[PATCH v4 08/10] Gen-12 display can decompress surfaces compressed by the media engine.

[Radhakrishna Sripada]

From: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com>

Detect the modifier corresponding to media compression to enable
display decompression for YUV and xRGB packed formats. A new modifier is
added so that the driver can distinguish between media and render
compressed buffers. Unlike render decompression, plane 6 and  plane 7 do not
support media decompression.

v2: Fix checkpatch warnings on code style (Lucas)

From DK:
Separate modifier array for planes that cannot decompress media (Ville)

v3: Support planar formats

[PATCH v4 09/10] drm/framebuffer/tgl: Format modifier for Intel Gen 12 render compression with Clear Color

[Radhakrishna Sripada]

Gen12 display can decompress surfaces compressed by render engine with Clear Color, add
a new modifier as the driver needs to know the surface was compressed by render engine.

V2: Description changes as suggested by Rafael.
V3: Mention the Clear Color size of 64 bits in the comments(DK)

[PATCH v4 10/10] drm/i915/tgl: Add Clear Color supoort for TGL Render Decompression

[Radhakrishna Sripada]

Render Decompression is supported with Y-Tiled main surface. The CCS is
linear and has 4 bits of data for each main surface cache line pair, a
ratio of 1:256. Additional Clear Color information is passed from the
user-space through an offset in the GEM BO. Add a new modifier to identify
and parse new Clear Color information and extend Gen12 render decompression
functionality to the newly added modifier.

v2: Fix has_alpha flag for modifiers, omit CC modifier during initial
    plane config(Matt). Fix Lookup error.
v3: Fix the panic while running kms_cube
v4: Add alignment check and reuse the comments for ge12_ccs_formats(Matt)

[PATCH v4 09/10] drm/framebuffer/tgl: Format modifier for Intel Gen 12 render compression with Clear Color

[Radhakrishna Sripada]

Gen12 display can decompress surfaces compressed by render engine with Clear Color, add
a new modifier as the driver needs to know the surface was compressed by render engine.

V2: Description changes as suggested by Rafael.
V3: Mention the Clear Color size of 64 bits in the comments(DK)
v4: Fix trailing whitespaces

Re: [PATCH v4 10/10] drm/i915/tgl: Add Clear Color supoort for TGL Render Decompression

One minor typo and one documentation suggestion, but aside from fixing
those this patch looks good to me:

Reviewed-by: Matt Roper <matthew.d.roper@intel.com>

The previous patch that adds the modifier looks fine to me too, but I
figure we should leave it to whoever is working on the corresponding
userspace code to ack/rb that one.

I think it would be good to document what the expected format is, either
through comments and/or through a structure definition that describes
the exact layout.  As you mentioned before, some of the bytes provided
by the render engine aren't used by the display engine, so a more formal
description of the layout would make this easier to understand.

Documenting this in the previous patch would be the right place. So that
The description of the Color format is available at the modifier declaration.

[PATCH v5 09/10] drm/framebuffer/tgl: Format modifier for Intel Gen 12 render compression with Clear Color

[Radhakrishna Sripada]

Gen12 display can decompress surfaces compressed by render engine with Clear Color, add
a new modifier as the driver needs to know the surface was compressed by render engine.

V2: Description changes as suggested by Rafael.
V3: Mention the Clear Color size of 64 bits in the comments(DK)
v4: Fix trailing whitespaces
v5: Explain Clear Color in the documentation.

[PATCH v5 10/10] drm/i915/tgl: Add Clear Color supoort for TGL Render Decompression

[Radhakrishna Sripada]

Render Decompression is supported with Y-Tiled main surface. The CCS is
linear and has 4 bits of data for each main surface cache line pair, a
ratio of 1:256. Additional Clear Color information is passed from the
user-space through an offset in the GEM BO. Add a new modifier to identify
and parse new Clear Color information and extend Gen12 render decompression
functionality to the newly added modifier.

v2: Fix has_alpha flag for modifiers, omit CC modifier during initial
    plane config(Matt). Fix Lookup error.
v3: Fix the panic while running kms_cube
v4: Add alignment check and reuse the comments for ge12_ccs_formats(Matt)
v5: Fix typos and wrap comments(Matt)

A couple nit-picks here:
- It's not clear to me why "clear color" is capitalized but "color control surfaces" is not.
- It also isn't clear why "surfaces" is plural here but singular in the Y_TILED_CCS comment.
- A space is missing between "Color" and "(CCS_CC)". 
- Perhaps insert a "with" between "color control surface" and "clear color"?

> + *

I thought "CCS_CC" would be referring to the CCS with clear color, not the CCS
by itself. I can't find this term in the BSpec. Perhaps we shouldn't create a
new one here to avoid confusion?

[PATCH v6 10/10] drm/i915/tgl: Add Clear Color supoort for TGL Render Decompression

[Radhakrishna Sripada]

Render Decompression is supported with Y-Tiled main surface. The CCS is
linear and has 4 bits of data for each main surface cache line pair, a
ratio of 1:256. Additional Clear Color information is passed from the
user-space through an offset in the GEM BO. Add a new modifier to identify
and parse new Clear Color information and extend Gen12 render decompression
functionality to the newly added modifier.

v2: Fix has_alpha flag for modifiers, omit CC modifier during initial
    plane config(Matt). Fix Lookup error.
v3: Fix the panic while running kms_cube
v4: Add alignment check and reuse the comments for ge12_ccs_formats(Matt)
v5: Fix typos and wrap comments(Matt)
