[PATCH v3 00/14] New uAPI drm properties for color management

[PATCH v3 00/14] New uAPI drm properties for color management

[Werner Sembach]

I started work on my proposal for better color handling in Linux display
drivers: https://lkml.org/lkml/2021/5/12/764

In this 3rd revision everything except the generalised Broadcast RGB
implementation is included. I did however not yet include everything suggested
in the feedback for v1 and v2.

I rebased the patch series on drm-tip to have the latest changes in i915's
YCbCr420 handling and to make the intel-gfx ci not fail on merge anymore.

The read only properties are now correctly marked as immutable.

Some questions I already have:

I think Broadcast RGB is really no good name for the property as, at least in
theory, YCbCr can also be "Limited" or "Full". Should the new implementation
have a different name and make "Broadcast RGB" an alias for it? I propose
"preferred color range" as the new name.

I have not tested dp mst (both on AMD and Intel) as i have no adapter for it at
hand. If one can test it, please let me know if things break or not.

I found the DRM_MODE_PROP_ATOMIC flag and from the documentation it sounds like
"max bpc" (and "preferred color format" and "Broadcast RGB") should have it. Is
there a reason it doesn't?

I have not yet looked into dsc and dithering behaviour.

I have already submitted the first two patches separately to the lkml as they fix
potential bugs and don't introduce new uAPI.

[PATCH v3 01/14] drm/amd/display: Remove unnecessary SIGNAL_TYPE_HDMI_TYPE_A check

[Werner Sembach]

Remove unnecessary SIGNAL_TYPE_HDMI_TYPE_A check that was performed in the
drm_mode_is_420_only() case, but not in the drm_mode_is_420_also() &&
force_yuv420_output case.

Without further knowledge if YCbCr 4:2:0 is supported outside of HDMI, there is
no reason to use RGB when the display reports drm_mode_is_420_only() even on a
non HDMI connection.

This patch also moves both checks in the same if-case. This  eliminates an extra
else-if-case.

[PATCH v3 03/14] drm/uAPI: Add "active bpc" as feedback channel for "max bpc" drm property

[Werner Sembach]

Add a new general drm property "active bpc" which can be used by graphic drivers
to report the applied bit depth per pixel back to userspace.

While "max bpc" can be used to change the color depth, there was no way to check
which one actually got used. While in theory the driver chooses the best/highest
color depth within the max bpc setting a user might not be fully aware what his
hardware is or isn't capable off. This is meant as a quick way to double check
the setup.

In the future, automatic color calibration for screens might also depend on this
information being available.

[PATCH v3 03/14] drm/uAPI: Add "active bpc" as feedback channel for "max bpc" drm property

[Werner Sembach]

Add a new general drm property "active bpc" which can be used by graphic drivers
to report the applied bit depth per pixel back to userspace.

While "max bpc" can be used to change the color depth, there was no way to check
which one actually got used. While in theory the driver chooses the best/highest
color depth within the max bpc setting a user might not be fully aware what his
hardware is or isn't capable off. This is meant as a quick way to double check
the setup.

In the future, automatic color calibration for screens might also depend on this
information being available.

[PATCH v3 06/14] drm/uAPI: Add "active color format" drm property as feedback for userspace

[Werner Sembach]

Add a new general drm property "active color format" which can be used by
graphic drivers to report the used color format back to userspace.

There was no way to check which color format got actually used on a given
monitor. To surely predict this, one must know the exact capabilities of the
monitor, the GPU, and the connection used and what the default behaviour of the
used driver is (e.g. amdgpu prefers YCbCr 4:4:4 while i915 prefers RGB). This
property helps eliminating the guessing on this point.

In the future, automatic color calibration for screens might also depend on this
information being available.

[PATCH v3 09/14] drm/uAPI: Add "active color range" drm property as feedback for userspace

[Werner Sembach]

Add a new general drm property "active color range" which can be used by graphic
drivers to report the used color range back to userspace.

There was no way to check which color range got actually used on a given
monitor. To surely predict this, one must know the exact capabilities of the
monitor and what the default behaviour of the used driver is. This property
helps eliminating the guessing at this point.

In the future, automatic color calibration for screens might also depend on this
information being available.

[PATCH v3 12/14] drm/uAPI: Add "preferred color format" drm property as setting for userspace

[Werner Sembach]

Add a new general drm property "preferred color format" which can be used by
userspace to tell the graphic drivers to which color format to use.

Possible options are:
    - auto (default/current behaviour)
    - rgb
    - ycbcr444
    - ycbcr422 (not supported by both amdgpu and i915)
    - ycbcr420

In theory the auto option should choose the best available option for the
current setup, but because of bad internal conversion some monitors look better
with rgb and some with ycbcr444.

Also, because of bad shielded connectors and/or cables, it might be preferable
to use the less bandwidth heavy ycbcr422 and ycbcr420 formats for a signal that
is less deceptible to interference.

In the future, automatic color calibration for screens might also depend on this
option being available.

[PATCH v3 12/14] drm/uAPI: Add "preferred color format" drm property as setting for userspace

[Werner Sembach]

Add a new general drm property "preferred color format" which can be used by
userspace to tell the graphic drivers to which color format to use.

Possible options are:
    - auto (default/current behaviour)
    - rgb
    - ycbcr444
    - ycbcr422 (not supported by both amdgpu and i915)
    - ycbcr420

In theory the auto option should choose the best available option for the
current setup, but because of bad internal conversion some monitors look better
with rgb and some with ycbcr444.

Also, because of bad shielded connectors and/or cables, it might be preferable
to use the less bandwidth heavy ycbcr422 and ycbcr420 formats for a signal that
is less deceptible to interference.

In the future, automatic color calibration for screens might also depend on this
option being available.

I looked into DSC:

In both the amd and intel implementation it's:

max_bpc >= uncompressed bpc >= dsc bpc

Currently the patch is setting active bpc to the uncompressed bpc.

I gave the DSC specification a (very brief) look and did not find any 
obvious mention of some kind bpc upsampling, so I guess the dsc bpc is 
what the user actually sees in the end.

=> In the next version, active bpc will be set to dsc bpc in the case 
dsc is active.

I did not look into dithering yet, but it's next on my list.

I looked into DSC:

In both the amd and intel implementation it's:

max_bpc >= uncompressed bpc >= dsc bpc

Currently the patch is setting active bpc to the uncompressed bpc.

I gave the DSC specification a (very brief) look and did not find any 
obvious mention of some kind bpc upsampling, so I guess the dsc bpc is 
what the user actually sees in the end.

=> In the next version, active bpc will be set to dsc bpc in the case 
dsc is active.

I did not look into dithering yet, but it's next on my list.
