This patch simplifying the handling of modeset locks and atomic state for an atomic commit is based on https://lore.kernel.org/all/20210715184954.7794-2-ville.syrjala@linux.intel.com/ adding the helper to i915. I find this approach preferrable than open-coding the corresponding steps (fixed for me an atomic state reset during a DEADLK retry, which I missed in the open-coded version) and also better than the existing DRM_MODESET_LOCK_ALL_BEGIN/END macros for the reasons described in the above original patchset. This change takes the helper into use only for atomic commits during DDI hotplug handling, as a preparation for a follow-up patch adding a similar commit started from the same spot. Other places doing a driver-internal atomic commit is to be converted by a follow-up patchset.

Prevent downgrading the link training maximum lane count/rate if the sink is disconnected - and so the link training failure is expected. In such cases modeset failures due to the reduced max link params would be just confusing for user space (instead of which the correct thing it should act on is the sink disconnect signaled by a hotplug event, requiring a disabling modeset). v2: - Check the actual HPD state to handle the forced connector state case.

If a sink is disconnected it's expected that link training actions will fail on it, so downgrade the error messages about such actions to be a debug message. Such - expected - link training failures are more frequent after a follow up patch, after which an active TypeC link is reset after the sink is disconnected which also involves a link training. v2: - Check the actual HPD state to handle the forced connector state case.

During HW readout/sanitization CRTCs can be disabled only if they don't have an attached encoder (and so the encoder disable hooks don't need to be called). An upcoming patch will need to disable CRTCs also with an attached encoder, so add support for this. For bigjoiner configs the encoder disabling hooks require the slave CRTC states, so add these too to the atomic state. Since the connector atomic state is already up-to-date when the CRTC is disabled the connector state needs to be updated (reset) after the CRTC is disabled, make this so. Follow the proper order of disabling first all bigjoiner slaves, then any port synced CRTC slaves followed by the CRTC originally requested to be disabled. v2: - Fix calculating the bigjoiner_masters mask in a port sync config, (Ville) - Keep _noatomic suffix in intel_crtc_disable_noatomic(). (Ville) - Rebase on full CRTC state reset in this patchset, not requiring resetting the bigjoiner state separately and (instead) resetting the full atomic CRTC and related global state after all linked pipes got disabled. - Disable portsync slaves before a portsync master. - Disable a portsync master if a linked portsync slave is disabled. v3: (Ville) - Use s/u32/u8 for transcoder and pipe masks. - Use is_power_of_2() instead of hweight()==1.

Split calling the CRTC/encoder disabling hooks and updating the CRTC and DPLL object states from updating the CRTC and atomic state and other global state (BW, CDCLK, DBUF) into separate functions. When disabling a bigjoiner configuration the latter step can be done only after all the linked pipes are disabled, so this change prepares for that. No functional changes.

During HW state readout/sanitization an up-to-date connector atomic state will be required by a follow-up patch, which can disable CRTCs with an encoder (and calling the correct encoder hooks happens via the connector atomic state encoder pointer). So update the connector state already before the CRTC sanitize/disable step. For now this doesn't make a difference, since intel_modeset_update_connector_atomic_state() will update/enable the atomic state only for connectors that have an enabled encoder/CRTC. Such CRTCs/encoders will not be affected by intel_sanitize_crtc(). v2: Add comment about why the connector state needs to be up-to-date.

Make sure that the CRTC state is reset correctly, as expected after disabling the CRTC. In particular this change will: - Zero all the CSC blob pointers after intel_crtc_free_hw_state() has freed them. - Zero the shared DPLL and port PLL pointers and clear the corresponding CRTC reference flag in the PLL state. - Reset all the transcoder and pipe fields. v2: - Reset fully the CRTC state. (Ville) - Clear pipe active flags in the DPLL state. v3: - Clear only the CRTC reference flag and add a helper for this. (Ville) v4: - Rebased on previous patch, adding intel_unreference_shared_dpll_crtc() separately.

For a bigjoiner configuration display->crtc_disable() will be called first for the slave CRTCs and then for the master CRTC. However slave CRTCs will be actually disabled only after the master CRTC is disabled (from the encoder disable hooks called with the master CRTC state). Hence the slave PIPEDMCs can be disabled only after the master CRTC is disabled, make this so. intel_encoders_post_pll_disable() must be called only for the master CRTC, as for the other two encoder disable hooks. While at it fix this up as well. This didn't cause a problem, since intel_encoders_post_pll_disable() will call the corresponding hook only for an encoder/connector connected to the given CRTC, however slave CRTCs will have no associated encoder/connector.

The big switch+if statement mess in map_aux_ch() is illegible. Split up into cleaner per-platform arrays like we already have for the gmbus pins. We use enum aux_ch as the index and the VBT thing as the value. Slightly non-intuitive perhaps but if we did it the other way around we'd have problems with AUX_CH_A being zero, and thus any non-populated element would look like AUX_CH_A. v2: flip the index vs. value around TODO: Didn't bother with the platform variants beyond the ones that really need remapping, which means if the VBT is bogus we end up with a nonexistent aux ch. Might be nice to check this a bit better. Yet another bitmask in device info?

On g4x the hardware has only one audio/video DIP block. Thus only one HDMI port can transmit audio/infoframes at a time. Currently we pretend that multiple ports can do it at the same time, but that doesn't actually work for two reasons: - the state of the single hw block will get clobbered by the multiple ports, leading to state checker failures - the hardware will automagically disable audio/infoframe transmission when enabled on multiple ports To fix this let's allow only one of the ports to transmit audio/infoframes at a time. We'll just go over all the HDMI ports and pick the first one that is otherwise capable of audio/infoframes. Further HDMI ports will be treated as if they had a DVI sink connected. In order to compute this consistently we'll also need to always add all HDMI ports to the atomic state.

We'll be wanting to compute has_hdmi_sink a bit differently for some platforms. To that end compute it in the encoder .compute_config_hook() before we call intel_hdmi_compute_config(). intel_hdmi_compute_has_hdmi_sink() will do the basic lifting beyond any platform specific stuff.

Check for MODE_H_ILLEGAL before calculating max rates, lanes etc. Move comments about compressed bpp U6.4 format closer to where it is used.
