After cross-checking DSC models (20150914, 20161212, 20210623) change values in rc_parameters tables to follow config files present inside the DSC model. Handle two places, where i915 tables diverged from the model, by patching the rc values in the code. Note: I left one case uncorrected, 8bpp/10bpc/range_max_qp[0], because the table in the VESA DSC 1.1 sets it to 4. Reviewed-by:

If the output on a DP-alt link with its sink disconnected is kept enabled for too long (about 20 sec), then some IOM/TCSS firmware timeout will cause havoc on the PCI bus, at least for other GFX devices on it which will stop powering up. Since user space is not guaranteed to do a disabling modeset in time, switch such disconnected but active links to TBT mode - which is without such shortcomings - with a 2 second delay. If the above condition is detected already during the driver load/system resume sanitization step disable the output instead, as at that point no user space or kernel client depends on a consistent output state yet and because subsequent atomic modeset on such connectors - without the actual sink capabilities available - can fail. An active/disconnected port as above will also block the HPD status of other active/disconnected ports to get updated (stuck in the connected state), until the former port is disabled, its PHY is disconnected and a ~10 ms delay has elapsed. This means the link state for all TypeC ports/CRTCs must be rechecked after a CRTC is disabled due to the above reason. For this disconnect the PHY synchronously after the CRTC/port is disabled and recheck all CRTCs for the above condition whenever such a port is disabled. To account for a race condition during driver loading where the sink is disconnected after the above sanitization step and before the HPD interrupts get enabled, do an explicit check/link reset if needed from the encoder's late_register hook, which is called after the HPD interrupts are enabled already. v2: - Handle an active/disconnected port blocking the HPD state update of another active/disconnected port. - Cancel the delayed work resetting the link also from the encoder enable/suspend/shutdown hooks. - Rebase on the earlier intel_modeset_lock_ctx_retry() addition, fixing here the missed atomic state reset in case of a retry. - Fix handling of an error return from intel_atomic_get_crtc_state(). - Recheck if the port needs to be reset after all the atomic state is locked and async commits are waited on. v3: - Add intel_crtc_needs_link_reset(), instead of open-coding it, keep intel_crtc_has_encoders(). (Ville) - Fix state dumping and use a bitmask to track disabled CRTCs in intel_sanitize_all_crtcs(). (Ville) - Set internal in intel_atomic_state right after allocating it. (Ville) - Recheck all CRTCs (not yet force-disabled) after a CRTC is force-disabled for any reason (not only due to a link state) in intel_sanitize_all_crtcs(). - Reduce delay after CRTC disabling to 20ms, and use the simpler msleep(). - Clarify code comment about HPD behaviour in intel_sanitize_all_crtcs(). - Move all the TC link reset logic to intel_tc.c . - Cancel the link reset work synchronously during system suspend, driver unload and shutdown. v4: - Rebased on previous patch, which allows calling the TC port suspend/cleanup handlers without modeset locks held; remove the display driver suspended assert from the link reset work accordingly. v5: (Ville) - Remove reset work canceling from intel_ddi_pre_pll_enable(). - Track a crtc vs. pipe mask in intel_sanitize_all_crtcs(). - Add reset_link_commit() to clarify the intel_modeset_lock_ctx_retry loop.

Call the TypeC port flush_work and cleanup handlers without the modeset locks held. These don't require the locks, as the work takes - as it should be able to at any point in time - any locks it needs and by the time cleanup is called and after cleanup returns the encoder is not in use. This is required by the next patch canceling a TypeC port work synchronously during encoder suspend and shutdown, where the work can take modeset locks as well, hence the canceling must be done without holding the locks. I also considered moving the modeset locking down to each encoder suspend()/shutdown() hook instead, however locking the full modeset state for each encoder separately would be odd, and the bigger change - affecting all encoders - is beyond the scope of this patchset. v2: - Add a TODO: comment to remove modeset locks if no encoder depends on this.

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. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

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.

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. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

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.
