Subject: [PATCH v2 00/11] Enable CMRR in fixed-RR VRR path
Date: Tue, 16 Jun 2026 20:12:21 +0530 [thread overview]
Message-ID: <20260616144233.832276-1-mitulkumar.ajitkumar.golani@intel.com> (raw)
The existing CMRR fractional-timing code was permanently
disabled (if (!HAS_CMRR || true)), eDP-only, and relied
on a heuristic to guess when the fractional path was needed.
This series reworks it into a generic, debugfs-driven feature,
which later will be controlled via userspace when respective
uapi will be in-palce.
Mitul Golani (11):
drm/i915/vrr: add per-CRTC vrr/cmrr debugfs control
drm/i915/vrr: compute CMRR fractional timings generically
drm/i915/vrr: dump CMRR state in the crtc state dump
drm/i915/vrr: Move CMRR hw registers to fix refresh rate path
drm/i915/vrr: Enable/Disable CMRR based on enable/disable
preconditions
drm/i915/display: Move CMRR crtc_state members under VRR
drm/i915/vrr: Fix the CMRR enabling/disabling sequence
drm/i915/vrr: Compare state and HW registers if platform supports CMRR
drm/i915/vrr: Remove TODO as CMRR is exclusive to Adaptive mode
drm/i915/vrr: Return from CMRR compute config in case of PSR2 enabled
drm/i915/vrr: Enable cmrr
