[PATCH v5 00/17] New uAPI drm properties for color management

[PATCH v5 00/17] New uAPI drm properties for color management

[Werner Sembach]

Implementation of https://lkml.org/lkml/2021/5/12/764 now feature complete
albeit not fully tested.

I have now corrected the DSC behavior, but still no wait to test it.

Exact dithering behavior remains a mistery so in case dithering is active it's
not 100% clear what "active bpc" means, or where the "max bpc" limit is applied.

I have no DP MST splitter at hand. I tried my best to not break anything,
but if one who has one could test it would be very helpful.

Things on my TODO list:
    - add "min bpc" property
    - rewrite "preferred color format" to "force color format"
    - make "Broadcast RGB" only affect RGB on AMD too
    - remove unreachable enums of "active/preferred/force color format"

[PATCH v5 01/17] 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 v5 03/17] 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 color 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 v5 06/17] 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.

[Intel-gfx] [PATCH v5 06/17] 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 v5 09/17] 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.

[Intel-gfx] [PATCH v5 09/17] 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 v5 12/17] 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 v5 12/17] 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 v5 15/17] drm/uAPI: Move "Broadcast RGB" property from driver specific to general context

[Werner Sembach]

Add "Broadcast RGB" to general drm context so that more drivers besides
i915 and gma500 can implement it without duplicating code.

Userspace can use this property to tell the graphic driver to use full or
limited color range for a given connector, overwriting the default
behaviour/automatic detection.

Possible options are:
    - Automatic (default/current behaviour)
    - Full
    - Limited 16:235

In theory the driver should be able to automatically detect the monitors
capabilities, but because of flawed standard implementations in Monitors,
this might fail. In this case a manual overwrite is required to not have
washed out colors or lose details in very dark or bright scenes.

[PATCH v5 16/17] drm/i915/display: Use the general "Broadcast RGB" implementation

[Werner Sembach]

Change from the i915 specific "Broadcast RGB" drm property implementation
to the general one.

This commit delete all traces of the former "Broadcast RGB" implementation
and add a new one using the new driver agnoistic functions an variables.

[Intel-gfx] [PATCH v5 16/17] drm/i915/display: Use the general "Broadcast RGB" implementation

[Werner Sembach]

Change from the i915 specific "Broadcast RGB" drm property implementation
to the general one.

This commit delete all traces of the former "Broadcast RGB" implementation
and add a new one using the new driver agnoistic functions an variables.

After some testing I found out, that what I did here, was useless.

amdgpu actually never sets the quantization_range range in the 
hdmi_avi_infoframe and from that I guess any quantization range, besides 
the default one, is not implemented in multiple places.

Until limited RGB is properly implemented in amdgpu there kind of is no 
purpose of generalizing the Broadcast RGB switch.

After some testing I found out, that what I did here, was useless.

amdgpu actually never sets the quantization_range range in the 
hdmi_avi_infoframe and from that I guess any quantization range, besides 
the default one, is not implemented in multiple places

Until limited RGB is properly implemented in amdgpu there kind of is no 
purpose of generalizing the Broadcast RGB switch.

Hi Werner,

url:    https://github.com/0day-ci/linux/commits/Werner-Sembach/New-uAPI-drm-properties-for-color-management/20210630-231204
base:   git://anongit.freedesktop.org/drm-intel for-linux-next
config: i386-randconfig-m021-20210702 (attached as .config)

New smatch warnings:

Old smatch warnings:

I was wondering why the kbuild-bot was resending this same warning over
and over, but apparently it's the same issue copy and pasted to
different functions.
