2024-10-01drm/i915/intel_dp: Add support for forcing ultrajoinerAnkit Nautiyal
Allow forcing ultrajoiner through debugfs. v2: Minor refactoring of switch case logic.

2024-09-30drm/i915/dp: Add helper to compute num pipes requiredAnkit Nautiyal
Add a helper to compute the number of pipes required. This will depend on whether the joiner is required or is forced through the debugfs. If no joiner is required the helper returns 1. v2: -Return 1 if no joiner is required. (Ville) -Change the suffix from joined_pipes to num_pipes. (Ville) -Use number of pipes while calculating joined_pipe masks and max_dotclk. (Ville) v3: Simplify and rename the helper to intel_dp_num_joined_pipes(). Ville v4: Remove redundant 'fallthrough' statement.

2024-09-30drm/i915/display: Modify debugfs for joiner to force n pipesAnkit Nautiyal
At the moment, the debugfs for joiner allows only to force enable/disable pipe joiner for 2 pipes. Modify it to force join 'n' number of pipes, where n is a valid pipe joiner configuration. This will help in case of ultra joiner where 4 pipes are joined. v2: -Fix commit message to state that only valid joiner config can be forced. (Suraj) -Rename the identifiers to have INTEL_BIG/NONE_JOINER_PIPES. (Suraj) v3: -Avoid enum for joiner pipe counts, use bare numbers for better readability. (Ville) -Remove redundant prints from debugfs. (Ville) v4: Return -EINVAL if joiner forced to an invalid value. v5: Remove extra debug message. (Ville) v6: Minor fix in switch case.

2024-09-30drm/i915/display_debugfs: Allow force joiner only if supportedAnkit Nautiyal
Currently we support joiner only for DP encoder. Do not create the debugfs for joiner if DP does not support the joiner. This will also help avoiding cases where config has eDP MSO, with which we do not support joiner. v2: Check for intel_dp_has_joiner and avoid creating debugfs if not supported. (Ville) v3: Remove HAS_BIGJOINER check. (Ville) v4: Reverse checks for connector type and intel_dp_has_joiner(). (Ville) v5: Drop the local variable intel_dp and use intel_attached_dp() directly.

2023-11-14drm/i915/dsc: Add debugfs entry to validate DSC fractional bppSwati Sharma
DSC_Sink_BPP_Precision entry is added to i915_dsc_fec_support_show to depict sink's precision. Also, new debugfs entry is created to enforce fractional bpp. If Force_DSC_Fractional_BPP_en is set then while iterating over output bpp with fractional step size we will continue if output_bpp is computed as integer. With this approach, we will be able to validate DSC with fractional bpp. v2: Add drm_modeset_unlock to new line(Suraj) Signed-off-by: Swati Sharma <swati2.sharma@intel.com> Signed-off-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by: Mitul Golani <mitulkumar.ajitkumar.golani@intel.com> Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Sui Jingfeng <suijingfeng@loongson.cn> Link: https://patchwork.freedesktop.org/patch/msgid/20231110101020.4067342-8-ankit.k.nautiyal@intel.com
