2025-01-03drm/i915/hdmi: propagate errors from intel_hdmi_init_connector()Jani Nikula
Propagate errors from intel_hdmi_init_connector() to be able to handle them at callers. This is similar to intel_dp_init_connector().

We don't need to shout out loud if there is a Link Integrity Failure. This does not mean HDCP has failed, it is expected and taken into account in the HDCP Spec.

2024-11-04drm/i915/display: Allow fastset for change in HDR infoframeChaitanya Kumar Borah
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.

2024-01-08drm/i915: Init DRM connector polled field earlyImre Deak
After an HPD IRQ storm on a connector intel_hpd_irq_storm_detect() will set the connector's HPD pin state to HPD_MARK_DISABLED and the IRQ gets disabled. Subsequently intel_hpd_irq_storm_switch_to_polling() will enable polling for these connectors, setting the pin state to HPD_DISABLED, but only if the connector's base.polled field is set to DRM_CONNECTOR_POLL_HPD. intel_hpd_irq_storm_reenable_work() will reenable the IRQ - after 2 minutes - if the pin state is HPD_DISABLED. The connectors will be created with their base.polled field set to 0, which gets initialized only later in i915_hpd_poll_init_work() (using intel_connector::polled). If a storm is detected on a connector after it's created and IRQs are enabled on it - by intel_hpd_init() - and before its bease.polled field is initialized in the above work, the connector's HPD pin will stay in the HPD_MARK_DISABLED state - leaving the IRQ disabled indefinitely - and polling will not get enabled on it as intended. I can't see a reason for initializing base.polled in a delayed manner, so do this already when creating the connector, to prevent the above race condition.

2023-11-29drm/i915: Skip some timing checks on BXT/GLK DSI transcodersVille Syrjälä
Apparently some BXT/GLK systems have DSI panels whose timings don't agree with the normal cpu transcoder hblank>=32 limitation. This is perhaps fine as there are no specific hblank/etc. limits listed for the BXT/GLK DSI transcoders. Move those checks out from the global intel_mode_valid() into into connector specific .mode_valid() hooks, skipping BXT/GLK DSI connectors. We'll leave the basic [hv]display/[hv]total checks in intel_mode_valid() as those seem like sensible upper limits regardless of the transcoder used.

2023-10-31drm/i915: Move the g45 PEG band gap HPD workaround to the HPD codeVille Syrjälä
We are asked to reprogram PEG_BAND_GAP_DATA prior to enabling hotplug detection on the g45 HDMI/DP ports. Currently we do said reprogamming from the DP/HDMI connector initialization functions. That code should be mostly platform agnostic so clearly not the best place for this. Move the workaround to the place where we actually enable HPD detection.

2023-09-15drm/i915/hdmi: Remove old i2c symlinkVille Syrjälä
Remove the i915 specific i2c-N symlink from HDMI connectors. This was added to sort of mirror the DP connectors that alreayd had their aux ch based i2c adapter sitting beneath them in the sysfs hierarchy. But now that we have the standard "ddc" symlink approach provided by the core let's switch to that fully. I don't think anything beyond igt depends on this.

2023-08-11drm/i915: Avoid endless HPD poll detect loop via runtime suspend/resumeImre Deak
The issue fixed in commit a8ddac7c9f06 ("drm/i915: Avoid HPD poll detect triggering a new detect cycle") on VLV, CHV is still present on platforms where the display hotplug detection functionality is available whenever the device is in D0 state (hence these platforms switch to HPD polling only when the device is runtime suspended). The above commit avoids an endless i915_hpd_poll_init_work() -> connector detect loop by making sure that by the end of i915_hpd_poll_init_work() all display power references acquired by the connector detect functions which can trigger a new cycle (display core power domain) are dropped. However on platforms where HPD polling is enabled/disabled only from the runtime suspend/resume handlers, this is not ensured: for instance eDP VDD, TypeC port PHYs and the runtime autosuspend delay may still keep the device runtime resumed (via a power reference acquired during connector detection and hence result in an endless loop like the above). Solve the problem described in the above commit on all platforms, by making sure that a i915_hpd_poll_init_work() -> connector detect sequence can't take any power reference in the first place which would trigger a new cycle, instead of relying on these power references to be dropped by the end of the sequence. With the default runtime autosuspend delay (10 sec) this issue didn't happen in practice, since the device remained runtime resumed for the whole duration of the above sequence. CI/IGT tests however set the autosuspend delay to 0, which makes the problem visible, see References: below. Tested on GLK, CHV. v2: Don't warn about a requeued work, to account for disabling polling directly during driver loading, reset and system resume.
