The below patches add support for data flow metering as mentioned in the section 6.5.6 FRL data flow metering of HDMI 2.1 specification.
Add functions to calclulate the DFM parameters for the given frl config, which is further used to evaluate the data flow metering requirement as specified in the spec.
As per the spec the below patches implement the frl capacity computation functions for both compressed and uncompressed video. Finally exposing 1 function each for compressed and uncompressed video to figure out if the data flow metering requirement is met or not.
Ankit Nautiyal (1): drm/hdmi21: Add support for DFM calculation with DSC
Vandita Kulkarni (4): drm/hdmi21: Define frl_dfm structure drm/hdmi21: Add non dsc frl capacity computation helpers drm/hdmi21: Add helpers to verify non-dsc DFM requirements drm/hdmi21: Add frl_dfm_helper to Makefile
