drm/i915/hdcp: Fix when the first read and write are retried

2024-11-19T08:11:11Z

Make sure that the first read/write in hdcp2_authentication_key_exchange are only retried when we have either DP/DPMST encoder connected, since we do this to give docks and dp encoders some extra time to get their HDCP DPCD registers ready only for DP/DPMST encoders as this issue is only observed here no need to burden other encoders with extra retries as this causes the HDMI connector to have some other timing issue and fails HDCP authentication. --v2 -Add intent of patch [Chaitanya] -Add reasoning for loop [Jani] -Make sure we forfiet the 50ms wait for non DP/DPMST encoders. --v3 -Remove the is_dp_encoder check [Jani/Chaitanya] -Make the commit message more clearer [Jani] Fixes: 9d5a05f86d2f ("drm/i915/hdcp: Retry first read and writes to downstream") Signed-off-by: Suraj Kandpal Reviewed-by: Chaitanya Kumar Borah Link: https://patchwork.freedesktop.org/patch/msgid/20241104035951.517837-1-suraj.kandpal@intel.com (cherry picked from commit 44499559496c1dac43583f4387d38de1b612a69b) Signed-off-by: Tvrtko Ursulin

drm/i915: Grab intel_display from the encoder to avoid potential oopsies

Grab the intel_display from 'encoder' rather than 'state' in the encoder hooks to avoid the massive footgun that is intel_sanitize_encoder(), which passes NULL as the 'state' argument to encoder .disable() and .post_disable().

drm/i915/display: Allow fastset for change in HDR infoframe

2024-11-04T08:26:53Z

Changes in Dynamic Range and Mastering infoframe should not trigger a full modeset. Therefore, allow fastset. DP SDP programming is already hooked up in the fastset flow but HDMI AVI infoframe update is not, add it. Any other infoframe that can be fastset should be added to the helper intel_hdmi_fastset_infoframes(). v3: - Create a wrapper intel_ddi_update_pipe_hdmi to stick to uniform naming (Jani) - Do not disable HDMI AVI infoframe if already disabled (Uma) v2: - Update HDMI AVI infoframe during fastset.

drm/i915/psr: WA for panels stating bad link status after PSR is enabled

2024-11-04T08:37:22Z

We are currently seeing unexpected link trainings with several different eDP panels. These are caused by these panels stating bad link status in their dpcd registers. This can be observed by doing following test: 1. Boot up without Xe module loaded 2. Load Xe module with PSR disabled: $ modprobe xe enable_psr=0 3. Read panel link status register $ dpcd_reg read --offset 0x200e --count=1 0x200e: 00 4. Enable PSR, sleep for 2 seconds and disable PSR again: $ echo 0x1 > /sys/kernel/debug/dri/0/i915_edp_psr_debug $ echo "-1" > /sys/kernel/debug/dri/0000:00:02.0/xe_params/enable_psr $ echo 0x0 > /sys/kernel/debug/dri/0/i915_edp_psr_debug $ sleep 2 $ cat /sys/kernel/debug/dri/0/i915_edp_psr_status | grep status $ echo 0x1 > /sys/kernel/debug/dri/0/i915_edp_psr_debug Source PSR/PanelReplay status: DEEP_SLEEP [0x80310030] 5. Now read panel link status registers again: $ dpcd_reg read --offset 0x200e --count=1 0x200e: 80 Workaround this by not trusting link status registers after PSR is enabled until first short pulse interrupt is received. v2: - clear link_ok flag on pipe disable - remove useless comment - modify intel_dp_needs_link_retrain return statement Signed-off-by: Jouni Högander Reviewed-by: Imre Deak Link: https://patchwork.freedesktop.org/patch/msgid/20241029122415.1789528-1-jouni.hogander@intel.com

drm/i915/dp: Add FEC Enable Retry mechanism

2024-11-04T07:51:21Z

Currently, even though there is a bit to control FEC enable/disable individually, the FEC Decode Enable sequence is sent by the SOC only once TRANS_CONF enable is set. This ties the FEC enabling too tightly to modeset and therefore cannot be re-issued (in case of failure) without a modeset. From PTL, FEC_DECODE_EN sequence can be sent to a DPRX independent of TRANS_CONF enable. This allows us to re-issue an FEC_DECODE_EN sequence without a modeset. Hence allowing us to have a retry mechanism in case the DPRX does not respond with an FEC_ENABLE within certain amount of time. While at it, replace struct drm_i915_private with struct intel_display v4: - More code refactor [Jani] - use struct intel_display [Jani] - Optimize logging [Jani] v3: - Make the commit message more legible [Jani] - Refactor code to re-use existing code [Jani] - Do away with platform dependent FEC enable checks [Jani] v2: - Refactor code to avoid duplication and improve readability [Jani] - In case of PTL, wait for FEC status directly after FEC enable [Srikanth] - Wait for FEC_ENABLE_LIVE_STATUS to be cleared before re-enabling FEC [Srikanth] Signed-off-by: Chaitanya Kumar Borah Reviewed-by: Jani Nikula Signed-off-by: Suraj Kandpal Link: https://patchwork.freedesktop.org/patch/msgid/20241024061002.4085137-1-chaitanya.kumar.borah@intel.com
