allocate doorbell space in each PDD during process creation.
Currently, KFD manages its own doorbell space but for some

Don't check drm_crtc_state::active for this either, per its

 * Hence drivers must not consult @active in their various

atomic_remove_fb disables the CRTC as needed for disabling the primary

This prevents at least the following problems if the primary plane gets
disabled (e.g. due to destroying the FB assigned to the primary plane,
as happens e.g. with mutter in Wayland mode):

* If the cursor plane was enabled, changing the legacy DPMS property

still physically plugged in.

[how]
Added a new option to debugfs entry "trigger_hotplug".
It emulates hotplug irq handling scenario by clearing
DC and DM connector states.
It can be triggered with the following command:

echo 0 > /sys/kernel/debug/dri/0/DP-X/trigger_hotplug

drm/amd/display: Add DSC force disable to dsc_clock_en debugfs entry

[why]
For debug purposes we want not to enable DSC on certain connectors
even if algorithm deesires to do so, instead it should enable DSC
on other capable connectors or fail the atomic check.

[how]
Adding the third option to connector's debugfs entry dsc_clock_en.

Accepted inputs:
     0x0 - connector is using default DSC enablement policy
     0x1 - force enable DSC on the connector, if it supports DSC
     0x2 - force disable DSC on the connector, if DSC is supported

Ex. # echo 0x2 > /sys/kernel/debug/dri/0/DP-1/dsc_clock_en

drm/amd/display: Multi display cause system lag on mode change

[Why]
DCValidator is created/destroyed repeatedly for cofunctional validation
which causes a lot of memory thrashing, particularly when Driver Verifer
is enabled.

[How]
Implement a basic caching algorithm that will cache DCValidator with a
matching topology.  When a match is found, the DCValidator can be
reused.  If there is no match, a new one will be created and inserted
into the cache if there is space or an unreference entry can be evicted.

drm/amd/display: Disable idle optimization when PSR is enabled

[Why]
Idle optimization and PSR conflict each other. If both enabled
at the same time, display flickering will be observed.

[How]
Disable idle optimization when PSR is enabled.

drm/amd/display: Don't use DRM_ERROR() for DTM add topology

[Why]
Previously we were only calling add_topology when hdcp was being enabled.
Now we call add_topology by default so the ERROR messages are printed if
the firmware is not loaded.

This error message is not relevant for normal display functionality so
no need to print a ERROR message.

[How]
Change DRM_ERROR to DRM_INFO

drm/amd/display: Compare plane when looking for pipe split being lost

[Why]
There are situations where we go from 2 pipe to 1 pipe in MPO, but this
isn't a pipe split being lost -- it's a plane disappearing in (i.e. video overlay
goes away) so we lose one pipe. In these situations we don't want to
disable the pipe in a separate operation from the rest of the pipe
programming sequence. We only want to disable a pipe in a
separate operation when we're actually disabling pipe split.

[How]
Make sure the pipe being lost has the same stream AND plane
as the old top pipe to ensure.

drm/amd/display: Enabling PSR on DCN30 on driver side

[Why]
PSR needs to be enabled on DCN30. This is the driver part of PSR
enablement.

Also disabled retired DMCU on driver side, since DMCU is
not supported on DCN30 anymore.

[How]
Add necessary changes to enable PSR on DCN30.
