2024-11-04drm/i915/dp: Add FEC Enable Retry mechanismChaitanya Kumar Borah
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 <chaitanya.kumar.borah@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241024061002.4085137-1-chaitanya.kumar.borah@intel.com

2024-10-31drm/i915/dp: Track source OUI validity explicitlyImre Deak
While updating the source OUI on the sink the driver should avoid writing the OUI if it's already up-to-date to prevent the sink from resetting itself in response to the update. On eDP - the only output type where the OUI was updated so far - the driver ensured this by comparing the current source OUI DPCD register values with the expected Intel OUI value, skipping the update in case of a match. On some non-eDP sinks - at least on Synaptics branch devices - this method doesn't work, since the source OUI DPCD registers read back as all 0, even after updating the registers. Handle the above kind of sinks by tracking when the OUI was updated and so should be valid, regardless of what the DPCD registers contain. eDP sinks reset the written source OUI value when the panel power is disabled, invalidate the OUI state accordingly. This is required by a follow-up patch updating the source OUI for non-eDP sink types as well. v2: Fix setting intel_dp::oui_valid=true, if the DPCD register contains already the expected value.

2024-10-31drm/i915/dp: Initialize the source OUI write timestamp alwaysImre Deak
If the source OUI DPCD register value matches the expected Intel OUI value, the write timestamp doesn't get updated leaving it at the 0 initial value if the OUI wasn't written before. This can lead to an incorrect wait duration in intel_dp_wait_source_oui(), since jiffies is not inited to 0 in general (on a 32 bit system INITIAL_JIFFIES is set to 5 minutes ahead of wrap-around). Fix this by intializing the write timestamp in the above case as well.

2024-10-31drm/i915/dp: Ensure panel power remains enabled during connector detectionImre Deak
The sink's capabilities, like the DSC caps, depend on the source OUI written to the sink's DPCD registers and so this OUI value should be valid for the whole duration of the detection. An eDP sink will reset this OUI value when the panel power is disabled, so prevent the disabling - happening by default after a 1 sec idle period - for the whole duration of detection. v2: Update the documentation for intel_pps_on().

2024-10-31drm/i915/dp: Flush modeset commits during connector detectionImre Deak
Make sure that a DP connector detection doesn't happen in parallel with an ongoing modeset on the connector. The reasons for this are: - Besides reading the capabilities, EDID etc. the detection may change the state of the sink (via the AUX bus), for instance by setting the LTTPR mode or the source OUI (the latter introduced by an upcoming patch). It's better to avoid such changes affecting an onging modeset in any way. - During a modeset's link training any access to DPCD registers, besides the registers used for link training should be avoided, at least in the LTTPR non-transparent and transparent link training modes. Such asynchronous accesses - besides connector detection - can also happen via the AUX device node for instance, for those a parallel modeset will have to be avoided in a similar way to the change in this patch. (A topic for a follow-up change.) - The source OUI written to an eDP sink is valid only while the panel power is enabled. A modeset on eDP will enable/disable the panel power synchronously; this should be prevented in the middle of the connector detection, to ensure a consistent sink state (which depends on the source OUI) for the whole duration of detection. The panel power could still get disabled during detection after an idle period (1 sec), this will be prevented by the next patch. v2: (Ville) - s/wait_for_crtc_hw_done/wait_for_connector_hw_done - Get drm_device using an intel_display instead of drm_i915_private ptr.

2024-10-30drm/i915/display: use a macro to initialize subplatformsJani Nikula
Make it easier to change the underlying structures by using a macro similar to PLATFORM() for initialization. The subplatform names in debug logs change slightly as they now reflect the enum rather than manually entered names. For example, RAPTORLAKE_S rather than RPL-S.
