CPU hive assignment currently assumes when a GPU hive is connected_to_cpu, there is only one hive in the system. Only assign CPUs to the hive if they are explicitly directly connected to the GPU hive to get rid of the need for this assumption. It's more efficient to do this when querying IO links since other non-CRAT info has to be filled in anyways. Also, stop re-assigning the same CPU to the same GPU hive if it has already been done before. Signed-off-by:

[Why] A display clock change hang can occur when switching between DIO and HPO enabled modes during the optimize_bandwidth in dc_commit_state_no_check call. This happens when going from 4k120 8bpc 420 to 4k144 10bpc 444. Display clock in the DIO case is 1200MHz, but pixel rate is 600MHz because the pixel format is 420. Display clock in the HPO case is less (800MHz?) because of ODM combine which results in a smaller divider. The DIO is still active in prepare but not active in the optimize which results in the hang occuring. During this change there are no planes on the stream so it's safe to apply the workaround, but dpms_off = false and signal type is not virtual. [How] Check for plane_count == 0, no planes on the stream. It's easiest to check pipe->plane_state == NULL as an equivalent check rather than trying to search for the stream status in the context associated with the stream, so let's do that. The primary, non MPO pipe should not have a NULL plane state. Reviewed-by:

The VBT send packet port selection was never updated for ICL+ where the 2nd link is on port B instead of port C as in VLV+ DSI. First, single link DSI needs to use the configured port instead of relying on the VBT sequence block port. Remove the hard-coded port C check here and make it generic. For reference, see commit f915084e ("drm/i915: Changes related to the sequence port no for") for the original VLV specific fix. Second, the sequence block port number is either 0 or 1, where 1 indicates the 2nd link. Remove the hard-coded port C here for 2nd link. (This could be a "find second set bit" on DSI ports, but just check the two possible options.) Third, sanity check the result with a warning to avoid a NULL pointer dereference.

Nathan Chancellor authored
When an attribute group is created with sysfs_create_group(), the ->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show() callback to kobj_attr_show(). kobj_attr_show() uses container_of() to get the ->show() callback from the attribute it was passed, meaning the ->show() callback needs to be the same type as the ->show() callback in 'struct kobj_attribute'. However, show_dynamic_id() has the type of the ->show() callback in 'struct device_attribute', which causes a CFI violation when opening the 'id' sysfs node under drm/card0/metrics. This happens to work because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast happens to allow the ->show() callback to still work. Change the type of show_dynamic_id() to match the ->show() callback in 'struct kobj_attributes' and update the type of sysfs_metric_id to match, which resolves the CFI violation.

Commit 7d8e9a90 ("drm/msm/dsi: move DSI host powerup to modeset time") caused sc7180 Chromebooks that use the parade-ps8640 bridge chip to fail to turn the display back on after it turns off. Unfortunately, it doesn't look easy to fix the parade-ps8640 driver to handle the new power sequence. The Linux driver has almost nothing in it and most of the logic for this bridge chip is in black-box firmware that the bridge chip uses. Also unfortunately, reverting the patch will break "tc358762". The long term solution here is probably Dave Stevenson's series [1] that would give more flexibility. However, that is likely not a quick fix. For the short term, we'll look at the compatible of the next bridge in the chain and go back to the old way for the Parade PS8640 bridge chip. If it's found that other bridge chips also need this workaround then we can add them to the list or consider inverting the condition. However, the hope is that the framework will not take too much longer to land and we won't have to add anything other than ps8640 here.
