[PATCH 3/3] drm/i915/display: Simplify helpers for getting DSC slices and bpp

[Ankit Nautiyal]

Genralize the helper for getting DSC slice count and compressed bpp
for HDMI sink supporting DSC.
This patch:
-Removes the assumption on the bpc and sends it as an argument for
calculating compressed bpc.
-Sends the resolution, and output format as parameters for which the
DSC paremeters are to be calculated instead of crtc_state.

[Intel-gfx] [PATCH 3/3] drm/i915/display: Simplify helpers for getting DSC slices and bpp

[Ankit Nautiyal]

Genralize the helper for getting DSC slice count and compressed bpp
for HDMI sink supporting DSC.
This patch:
-Removes the assumption on the bpc and sends it as an argument for
calculating compressed bpc.
-Sends the resolution, and output format as parameters for which the
DSC paremeters are to be calculated instead of crtc_state.

Please avoid including headers from other headers if at all possible.

Here we can forward declare

enum intel_output_format;

along with the other forward declarations below. Strictly speaking it's
not standards compliant to forward declare enums but it does work and we
use it all over the place.

The subject prefix should be "drm/edid:"

But I'm not sure these functions belong in drm_edid.c though. If you see
a function prefixed drm_hdmi_, this is not where you'd expect to find
it. Not sure what the right place should be though.

Please split this to two patches, adding the helpers in drm and using
them in i915. It's generally easier to manage that way if there's no
other reason to keep the changes together.

Re: [Intel-gfx] [PATCH 2/3] drm/drm_edid: Add helper to get max FRL rate for an HDMI sink

The subject prefix should be "drm/edid:"

But I'm not sure these functions belong in drm_edid.c though. If you see
a function prefixed drm_hdmi_, this is not where you'd expect to find
it. Not sure what the right place should be though.

Please split this to two patches, adding the helpers in drm and using
them in i915. It's generally easier to manage that way if there's no
other reason to keep the changes together.

Do you need to first make sure it's a HDMI 2.1 sink? That's what the
documentation makes you believe.

Right that make sense, will get rid of the header-file and forward 
declare the enum.

Thanks for the inputs Jani. Will address all of these in the next version.

Hmm. Another candidate which came to my mind was drm_connector,

but since the parsing of the edid got these values, I was thinking this 
might be the correct place.

The thing is that, these fields are the one that helps us to understand

Perhaps I should fix the documentation here:
