Synopsys has been working on some DRM core infrastructure patches for better handling of HDMI 2.0+ support by DRM drivers.

Five patches published on Wednesday add HDMI 2.0+ video mode handling in DRM core and allow for user-space for enabling of HDMI 2.0+ features. Though there is already some feedback to the patches on potentially just limiting the non-default aspect ratios behind a compatibility flag while letting the other HDMI 2.0 modes/features through that wouldn't break user-space compatibility.

64:27 and 256:135 are two of the new aspect ratio flags exposed in the HDMI 2.0 mode. There is also DRM EDID additions for HDMI 2.0 CEA video modes.


The patch series is under a "request for comments" flag on the dri-devel list.

Intel OTC developers have also been working on i915 DRM HDMI 2.0 changes with Geminilake supporting HDMI 2.0. That Intel work is coming together. On the AMD side, their HDMI 2.0 functionality is being worked on within the DC (DAL) code.
