Subject: [PATCH v8 0/7] Implement CMRR Support
Date: Thu, 9 May 2024 13:28:26 +0530 [thread overview]
Message-ID: <20240509075833.1858363-1-mitulkumar.ajitkumar.golani@intel.com> (raw)
CMRR is a display feature that uses adaptive sync
framework to vary Vtotal slightly to match the
content rate exactly without frame drops. This
feature is a variation of VRR where it varies Vtotal
slightly (between additional 0 and 1 Vtotal scanlines)
to match content rate exactly without frame drops
using the adaptive sync framework.
enable this feature by programing new registers for
CMRR enable, CMRR_M, CMRR_N, vmin=vmax=flipline.The
CMRR_M/CMRR_N ratio represents the fractional part
in (actual refresh rate/target refresh rate) * origVTotal.
--v6:
- CMRR handling in co-existatnce of LRR and DRRS
- Correct vtotal paramas accuracy and add 2 digit precision.
--v7:
- Rebased patches in-accordance to AS SDP merge.
- Add neccessary gaurd to prevent crtc_state mismatch
during intel_vrr_get_config.
-v8:
- Add support for AS SDP for CMRR.
- update palce holder for CMRR register(Jani).
- Make CMRR as subset of FAVT, as per comments in patch#3.
