[Intel-gfx] [PATCH v9 0/7] Enable YCbCr420 for VDSC

[Intel-gfx] [PATCH v9 0/7] Enable YCbCr420 for VDSC

[Suraj Kandpal]

This patch series aims to enable the YCbCr420 format
for DSC. Changes are mostly compute params related for
hdmi,dp and dsi along with the addition of new rc_tables
for native_420 and corresponding changes to macros used to
fetch them.

---v2
-add fields missed for vdsc_cfg [Vandita]
-add corresponding registers and writing to the [Vandita]

---v3
-add 11 bit left shift missed in nsl_bpg_offset calculation

---v4
-add display version check before writing in new pps register

---v5
-add helper to check if sink supports given format with DSC
-add debugfs entry to enforce DSC with YCbCr420 format only

--v6
-add patch to check dsc slice design requirement [Vandita]

--v7
-fix function name to intel_slice_dimensions_valid [Jani]
-remove full bspec link just add the ref number [Jani]
-remove patches for debug fs will float them as a seprate series
-Add more description for YUV420 Enablement [Vandita]

--v8
-fix slice width and height 2's multiple check
-fix minimum pixel requirement in slice check

--v9 
-Add debugfs entry to validate output format

Nit: You can drop "function" and "the" to truncate it, add o/p format to be clear.
Also I feel this can be squashed with 2nd patch. This seems to be a static function,
so scope is limited.

To stay consistent with rest of the file, please elaborate the function's purpose
and explain input parameters.

Skip the squashing comment, it's a drm core change. Its good to keep it separate.

This seems to be  wrong as it unconditionally overwrites the non-compress case.

[Intel-gfx] [PATCH v9 4/7] drm/i915: Enable YCbCr420 for VDSC

[Suraj Kandpal]

Implementation of VDSC for YCbCr420.
Add QP tables for 8,10,12 BPC from rc_tables.h in intel_qp_tables.c
(Derived from C-Model, which is given along with DSC1.2a Spec from Vesa)
intel_lookup_range_min/max_qp functons need to take into account the
output format. Based on that appropriate qp table need to be chosen.
Other rc_parameters need to be set where currently values for 444 format
is hardcoded in calculate_rc_parameters( ).
vdsc_cfg struct needs to be filled with output format information, where
these are hardcoded for 444 format.
Bspec: 49259

[Intel-gfx] [PATCH v9 5/7] drm/i915: Fill in native_420 field

[Suraj Kandpal]

Now that we have laid the groundwork for YUV420 Enablement
we fill up native_420 field in vdsc_cfg and add appropriate
checks wherever required.

---v2
-adding native_422 field as 0 [Vandita]
-filling in second_line_bpg_offset, second_line_offset_adj
and nsl_bpg_offset in vds_cfg when native_420 is true

---v3
-adding display version check to solve igt issue

--v7
-remove is_pipe_dsc check as its always true for D14 [Jani]

Are the sink caps taken into account somewhere else?

Nitpick, IMO "format != x && format != y" reads better than "!(format ==
x || format == y)"

Looking at it again I should move it after intel_dsc_compute_params and check sink capability 
If convert_rgb is set as true there

[Intel-gfx] [PATCH v10 5/7] drm/i915: Fill in native_420 field

[Suraj Kandpal]

Now that we have laid the groundwork for YUV420 Enablement
we fill up native_420 field in vdsc_cfg and add appropriate
checks wherever required.

---v2
-adding native_422 field as 0 [Vandita]
-filling in second_line_bpg_offset, second_line_offset_adj
and nsl_bpg_offset in vds_cfg when native_420 is true

---v3
-adding display version check to solve igt issue

--v7
-remove is_pipe_dsc check as its always true for D14 [Jani]

--v10
-keep sink capability check [Jani]
-move from !(x == y  || w == z) to x !=y && w != z [Jani]

The parameters we compute here are being programmed only for gen14. We should
limit the computation if they are going to be unused for prior platforms.

Can I remove "/* Gen 11 does not support YCbCr422 */ "
And just keep "/* We do not support YcBCr422 as of now */" or
Make it something like " Gen 11+ does not support YCbCr422 "

How about we make native_420 field of vdsc_cfg true only if DISPLAY_VER() >= 14
this should take care of not filling any extra fields or computations

I think "/* We do not support YcBCr422 as of now */" looks better.

[Intel-gfx] [PATCH v9 6/7] drm/i915/vdsc: Check slice design requirement

[Suraj Kandpal]

Add function to check if slice design requirements are being
met as defined in Bspec: 49259 in the section
Slice Design Requirement

--v7
-remove full bspec link [Jani]
-rename intel_dsc_check_slice_design_req to
intel_dsc_slice_dimensions_valid [Jani]

--v8
-fix condition to check if slice width and height are
of two
-fix minimum pixel in slice condition

If code reaches here, format is 422 which should be EINVAL as of now.

I missed this will fix it the condition should have been < 30000/15000

Not necessarily code can also reach here if all the slice dimension requirements are
met for any format also AFAIK INTEL_OUTPUT_FORMAT_YCBCR422 has not been defined
yet hence can be found in crtc_state->output_format

Oh yeah, missed that. But it would be good to have a check for YCBCR422 just to
restrict it here.

[Intel-gfx] [PATCH v9 7/7] drm/i915/dsc: Add debugfs entry to validate DSC output formats

[Suraj Kandpal]

From: Swati Sharma <swati2.sharma@intel.com>

DSC_Output_Format_Sink_Support entry is added to i915_dsc_fec_support_show
to depict if sink supports DSC output formats (RGB/YCbCr420/YCbCr444).
Also, new debugfs entry is created to enforce output format. This is
required because of our driver policy. For ex. if a mode is supported
in both RGB and YCbCr420 output formats by the sink, our policy is to
try RGB first and fall back to YCbCr420, if mode cannot be shown
using RGB. So, to test other output formats like YCbCr420 or YCbCr444,
we need a debugfs entry (force_dsc_output_format) to force this
output format.

output_formats is too generic a name to be non-static.

And maybe the place for the function is not here at all if it's needed
in multiple places.

Please don't duplicate the call to
intel_dp_compute_output_format(). Force the output format and try to use
the regular path otherwise. With the above approach, testing with the
forced output format uses a different path than is used otherwise.

Jani, crtc_state->output_format will be set to force_dsc_output_format 
in case we are forcing o/p format and in normal case output format is 
computed from intel_dp_output_format(). That's it. We are not using 
different path. Please suggest if you see this otherwise.

intel_output_format_name() would be in line with all the similar

I'd rather you left it here, no matter how out-of-place it feels,
instead of adding more static inlines anywhere.

My point is, the whole intel_dp_compute_output_format() is completely
different, with different checks and different error handling, with
intel_dp->force_dsc_output_format set.

If you use this for testing, you're not testing any of the checks here.

And it's more lines of code to maintain and understand. The next person
to come along to add more stuff here will wonder whether their changes
should apply to the special path as well, or only the regular path.

Consider what it would all look like if you handled
intel_dp->force_dsc_output_format in intel_dp_output_format() instead:

static enum intel_output_format
intel_dp_output_format(struct intel_connector *connector,
		       bool ycbcr_420_output)
{
	struct intel_dp *intel_dp = intel_attached_dp(connector);

	if (intel_dp->force_dsc_output_format)
		return intel_dp->force_dsc_output_format;

	if (intel_dp->dfp.rgb_to_ycbcr &&
	    intel_dp->dfp.ycbcr_444_to_420)
		return INTEL_OUTPUT_FORMAT_RGB;
...


BR,
Jani.

[Intel-gfx] [v10] drm/i915/dsc: Add debugfs entry to validate DSC output formats

[Swati Sharma]

DSC_Output_Format_Sink_Support entry is added to i915_dsc_fec_support_show
to depict if sink supports DSC output formats (RGB/YCbCr420/YCbCr444).
Also, new debugfs entry is created to enforce output format. This is
required because of our driver policy. For ex. if a mode is supported
in both RGB and YCbCr420 output formats by the sink, our policy is to
try RGB first and fall back to YCbCr420, if mode cannot be shown
using RGB. So, to test other output formats like YCbCr420 or YCbCr444,
we need a debugfs entry (force_dsc_output_format) to force this
output format.

v2: -Func name changed to intel_output_format_name() (Jani N)
    -Return forced o/p format from intel_dp_output_format() (Jani N)

[Intel-gfx] [v11] drm/i915/dsc: Add debugfs entry to validate DSC output formats

[Swati Sharma]

DSC_Output_Format_Sink_Support entry is added to i915_dsc_fec_support_show
to depict if sink supports DSC output formats (RGB/YCbCr420/YCbCr444).
Also, new debugfs entry is created to enforce output format. This is
required because of our driver policy. For ex. if a mode is supported
in both RGB and YCbCr420 output formats by the sink, our policy is to
try RGB first and fall back to YCbCr420, if mode cannot be shown
using RGB. So, to test other output formats like YCbCr420 or YCbCr444,
we need a debugfs entry (force_dsc_output_format) to force this
output format.

v2: -Func name changed to intel_output_format_name() (Jani N)
    -Return forced o/p format from intel_dp_output_format() (Jani N)
v3: -output_format_str[] to remain static (Jani N)

[Intel-gfx] [PATCH v8 0/6] Enable YCbCr420 for VDSC

[Suraj Kandpal]

This patch series aims to enable the YCbCr420 format
for DSC. Changes are mostly compute params related for
hdmi,dp and dsi along with the addition of new rc_tables
for native_420 and corresponding changes to macros used to
fetch them.

---v2
-add fields missed for vdsc_cfg [Vandita]
-add corresponding registers and writing to the [Vandita]

---v3
-add 11 bit left shift missed in nsl_bpg_offset calculation

---v4
-add display version check before writing in new pps register

---v5
-add helper to check if sink supports given format with DSC
-add debugfs entry to enforce DSC with YCbCr420 format only

--v6
-add patch to check dsc slice design requirement [Vandita]

--v7
-fix function name to intel_slice_dimensions_valid [Jani]
-remove full bspec link just add the ref number [Jani]
-remove patches for debug fs will float them as a seprate series
-Add more description for YUV420 Enablement [Vandita]

--v8
-fix slice width and height 2's multiple check
-fix minimum pixel requirement in slice check
