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.
There have been discussions prior to this series in which some patches
have gotten rb and can be found in the below link
https://patchwork.freedesktop.org/series/113729

Ankit Nautiyal (2):
  drm/dp_helper: Add helper to check DSC support with given o/p format
  drm/i915/dp: Check if DSC supports the given output_format

Suraj Kandpal (4):
  drm/i915: Adding the new registers for DSC
  drm/i915: Enable YCbCr420 for VDSC
  drm/i915/display: Fill in native_420 field
  drm/i915/vdsc: Check slice design requirement

Swati Sharma (1):
  drm/i915/dsc: Add debugfs entry to validate DSC output formats

I think it would be useful to get [1] from Dmitry merged to
drm-misc-next first, have that in drm-next, and again backmerged to
drm-intel-next before this. At least patches 1-5.

There's not much point in all drivers duplicating the parameters, and we
need to move towards common code. Dmitry has been helpful in
contributing this to us.

BR,
Jani.

Note, while I slightly reworked the calculate_rc_params() function, I 
did not touch the intel_qp_tables (mostly since we do not need them for 
drm/msm (at least for now). Our current plan is to use fixed params (at 
least in the short notice). We might have to reconsider it at some point.

However it might be wise to merge them with amdgpu's qp tables. amdgpu 
driver also contains code to calculate RC params. It might be worth 
moving RC calculation to the common helper.

Yeah, this isn't a big conflict, but AFAICT it'll conflict in
intel_vdsc.c.

Agreed.

Hi Jani,
Maarten has acked the patch series to be merged through drm-intel and in the meantime
I will work with Dmitry to pull the common code to avoid duplication

I wanted to check, are there any updates from your side regarding the 
series at [1] ?

Please excuse me for being slightly stubborn here. We are slowly getting 
other patches piled up with dependency on this series. It is fine that 
it doesn't get into 6.4 (which it probably definitely missed by now), 
but we would like to know if we have to redo/update anything or if it is 
fine as is and it is going to be merged by i915 in 6.5 cycle.

Thank you for the understanding.
