Computes AS SDP values based on the display configuration, ensuring proper handling of Variable Refresh Rate (VRR) in the context of Adaptive Sync. --v2: - Update logging to Patch-1 - use as_sdp instead of async - Put definitions to correct placeholders from where it is defined. - Update member types of as_sdp for uniformity. - Correct use of REG_BIT and REG_GENMASK. - Remove unrelated comments and changes. - Correct code indents. - separate out patch changes for intel_read/write_dp_sdp. --v3: - Add VIDEO_DIP_ASYNC_DATA_SIZE definition and comment in as_sdp_pack function to patch 2 as originally used there. [Patch 2]. - Add VIDEO_DIP_ENABLE_AS_HSW flag to intel_dp_set_infoframes [Patch 3]. --v4: - Add check for HAS_VRR before writing AS SDP. [Patch 3]. --v5: - Add missing check for HAS_VRR before reading AS SDP as well [Patch 3]. --v6: - Rebase all patches. - Compute TRANS_VRR_VSYNC. -v7: - Move vrr_vsync_start/end to compute config. - Use correct function for drm_debug_printer. -v8: - Code refactoring. - Update, VSYNC_START/END macros to VRR_VSYNC_START/END.(Ankit) - Update bit fields of VRR_VSYNC_START/END.(Ankit) - Send patches to dri-devel.(Ankit) - Update definition names for AS SDP which are starting from HSW, as these defines are applicable for ADLP+.(Ankit) - Remove unused bitfield define, AS_SDP_ENABLE. - Add support in drm for Adaptive Sync sink status, which can be used later as a check for read/write sdp. (Ankit) -v9: - Add enum to operation mode to represent different AVT and FAVT modes. (Ankit) - Operation_mode, target_rr etc should be filled from as_sdp struct. (Ankit) - Fill as_sdp->*All Params* from compute config, read from the sdp. (Ankit) - Move configs to the appropriate patch where it used first.(Ankit) - There should be a check if as sdp is enable is set or not. (Ankit) - Add variables in crtc state->vrr for ad sdp enable and operation mode. (Ankit) - Use above variables for tracking AS SDP. (Ankit) - Revert unused changes. (Ankit) -v10: - Send Patches to dri-devel (Ankit). -v11: - Remove as_sdp_mode and enable from crtc_state. - For consistency, update ADL_ prefix or post fix as required. - Add a comment mentioning current support of DP_AS_SDP_AVT_FIXED_VTOTAL. - Add state checker for AS_SDP infoframe enable. - Add PIPE_CONF_CHECK_I(vrr.vsync_start/end). - Read/write vrr_vsync params only when we intend to send adaptive_sync sdp. -v12: - Update cover letter -v13: - Add correct place holder and name change for AS_SDP_OP_MODE. - Separate i915 changes from drm changes. - Remove extra lines. - Check if AS_SDP bit is set in crtc_state->infoframes.enable. If not return. - Check for HAS_AS_SDP() before setting VIDEO_DIP_ENABLE_AS_ADL mask. - Just use drm/i915/dp in subject line. - Drop conn_state from intel_dp_compute_as_sdp, as not used. - Remove fullstop in subject line. - crtc_state->infoframes.enable, to add on correct place holder.
