> -----Original Message----- > From: Intel-gfx <intel-gfx-bounces@lists.freedesktop.org> On Behalf Of Mitul > Golani > Sent: Monday, June 10, 2024 8:18 AM > To: intel-gfx@lists.freedesktop.org > Cc: Nautiyal, Ankit K <ankit.k.nautiyal@intel.com> > Subject: [PATCH v15 0/9] Implement CMRR Support > > 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. > > -v9: > - Add CMRR register definitions to separate intel_vrr_reg.h. > - Remove cmrr_enabling/disabling, use vrr.enable instead. > - Update AS SDP pack function to accomodate target_rr_divider. > - Remove duplicated lines to compute vrr_vsync params. > - Set cmrr.enable with a separate patch at last. > > -v10: > - Separate VRR related register definitions. > - Add dependency header intel_display_reg_defs.h. > - Rename file name to intel_vrr_regs.h instead of reg.h. > - Revert removed line. > - Since vrr.enable and cmrr.enable are not mutually exclusive, handle > accordingly. > - is_edp is not required inside is_cmrr_frac_required function. > - Add video_mode_required flag for future enhancement. > - Correct cmrr_m/cmrr_n calculation. > - target_rr_divider is bools so handle accordingly. > > -v11: > - Move VRR related register and bits to separate file intel_vrr_regs.h. > - Correct file header macro to intel_vrr_regs.h. > - Remove adding CMRR flag to vrr_ctl register during set_transcoder_timing. > - Replace vrr.enable flag to cmrr.enable where added mistakenly. > - Move cmrr computation patch to last and set other other required > params before computing cmrr.enable. > > -v12: > - Add patch to fix check patch issues for VRR related registers in i915_reg.h > then move them to intel_vrr_regs.h with separate patch. > > -v13: > - Reverted unrelated patches while rebase. > > -v14: > - Fix all indentations for VRR related registes in Patch#1 > > -v15: > - Rebase. > Thanks for the patches and reviews everyone Pushed-to drm-intel-next > Mitul Golani (9): > gpu/drm/i915: Update indentation for VRR registers and bits > drm/i915: Separate VRR related register definitions > drm/i915: Define and compute Transcoder CMRR registers > drm/i915: Update trans_vrr_ctl flag when cmrr is computed > drm/dp: Add refresh rate divider to struct representing AS SDP > drm/i915/display: Add support for pack and unpack > drm/i915/display: Compute Adaptive sync SDP params > drm/i915/display: Compute vrr vsync params > drm/i915: Compute CMRR and calculate vtotal > > drivers/gpu/drm/i915/display/intel_display.c | 24 +++- > .../drm/i915/display/intel_display_device.h | 1 + > .../drm/i915/display/intel_display_types.h | 6 + > drivers/gpu/drm/i915/display/intel_dp.c | 18 ++- > drivers/gpu/drm/i915/display/intel_vrr.c | 128 ++++++++++++++++-- > drivers/gpu/drm/i915/display/intel_vrr_regs.h | 127 +++++++++++++++++ > drivers/gpu/drm/i915/i915_reg.h | 100 -------------- > include/drm/display/drm_dp_helper.h | 1 + > 8 files changed, 286 insertions(+), 119 deletions(-) create mode 100644 > drivers/gpu/drm/i915/display/intel_vrr_regs.h > > -- > 2.25.1
