[Why]
These registers should not be read from driver and triggering the
security violation when DMCUB work times out and diagnostics are
collected blocks Z8 entry.

[Why]
Compositors have different ways of assigning surfaces to DRM planes for
render offloading. It may decide between various strategies: overlay,
underlay, or a mix of both (see here for more info:
https://gitlab.freedesktop.org/emersion/libliftoff/-/issues/76)
One way for compositors to implement the underlay strategy is to assign
a higher zpos to the DRM_PRIMARY plane than the DRM_OVERLAY planes,
effectively turning the DRM_OVERLAY plane into an underlay plane.
Today, amdgpu attaches an immutable zpos of 0 to the DRM_PRIMARY plane.
This however, is an arbitrary restriction. DCN pipes are general
purpose, and can be arranged in any z-order. To support compositors
using this allocation scheme, we can set a non-zero immutable zpos for
the PRIMARY, allowing the placement of OVERLAYS (mutable zpos range
0-254) beneath the PRIMARY.
[How]
Assign a zpos = #no of OVERLAY planes to the PRIMARY plane. Then, clean
up any assumptions in the driver of PRIMARY plane having the lowest
zpos.

[Why]
DCN is the display hardware for amdgpu. DRM planes are backed by DCN
hardware pipes, which carry pixel data from one end (memory), to the
other (output encoder).
Each DCN pipe has the ability to blend in a cursor early on in the
pipeline. In other words, there are no dedicated cursor planes in DCN,
which makes cursor behavior somewhat unintuitive for compositors.
For example, if the cursor is in RGB format, but the top-most DRM plane
is in YUV format, DCN will not be able to blend them. Because of this,
amdgpu_dm rejects all configurations where a cursor needs to be enabled
on top of a YUV formatted plane.
From a compositor's perspective, when computing an allocation for
hardware plane offloading, this cursor-on-yuv configuration result in an
atomic test failure. Since the failure reason is not obvious at all,
compositors will likely fall back to full rendering, which is not ideal.
Instead, amdgpu_dm can try to accommodate the cursor-on-yuv
configuration by opportunistically reserving a separate DCN pipe just
for the cursor. We can refer to this as "overlay cursor mode". It is
contrasted with "native cursor mode", where the native DCN per-pipe
cursor is used.
[How]
On each crtc, compute whether the cursor plane should be enabled in
overlay mode. If it is, mark the CRTC as requesting overlay cursor mode.
Overlay cursor should be enabled whenever there exists a underlying
plane that has YUV format, or is scaled differently than the cursor. It
should also be enabled if there is no underlying plane, or if underlying
planes do not cover the entire CRTC.
During DC validation, attempt to enable a separate DCN pipe for the
cursor if it's in overlay mode. If that fails, or if no overlay mode is
requested, then fallback to native mode.
v2:
* Update commit message for when overlay cursor should be enabled
* Also consider scale and no-underlying-plane case (cursor on crtc bg)
* Consider all underlying planes when determinig overlay/native, not
just the plane immediately beneath the cursor, as it may not cover the
entire CRTC.
* Fix typo s/decending/descending/
* Force native cursor on pre-DCN hardware

[why]
We need to decrease ODM slice when adding or removing planes because MPO
support takes precedence over dynamic ODM combine. However there is a case where
we remove ODM combine even for ODM combine required timing in the initial new
dc state. This is normally okay because ODM will be added back after we pass DML
bandwidth validation. However since we remove ODM combine in the initial new
state, the previous ODM pipe allocation is lost. This may cause the new plane to
take away the original secondary OPP head pipe that is still required in the new
state.
For a timing that requires ODM 2:1 but optimized with ODM 4:1, if we add an MPO
plane, we will not have enough pipe to preserve ODM 4:1. In this case we should
reduce ODM slice count then try to add the MPO plane again. By reducing, we are
gradually remove 1 ODM slice from right most side one at a time until we have
enough free pipes for the new plane. If we remove ODM combine entirely, we could
use the pipe at ODM slice index 1 as a DPP pipe for the new plane. But ODM slice
1 is still needed as the timing requires ODM 2:1. This transition is not
seamless and user will see corruption on the screen.
[how]
Remove single ODM slice one at time until we have enough pipes for a new plane.
Remove previous logic to always remove ODM combine entirely.

This reverts commit b8c415e3bf98 ("drm/amdgpu: take runtime pm reference
when we attach a buffer") and commit 425285d39afd ("drm/amdgpu: add amdgpu
runpm usage trace for separate funcs").
Taking a runtime pm reference for DMA-buf is actually completely
unnecessary and even dangerous.
The problem is that calling pm_runtime_get_sync() from the DMA-buf
callbacks is illegal because we have the reservation locked here
which is also taken during resume. So this would deadlock.
When the buffer is in GTT it is still accessible even when the GPU
is powered down and when it is in VRAM the buffer gets migrated to
GTT before powering down.
The only use case which would make it mandatory to keep the runtime
pm reference would be if we pin the buffer into VRAM, and that's not
something we currently do.

Use dc_wake_and_execute_gpint with DM_DMUB_WAIT_TYPE_WAIT_WITH_REPLY to
get the replay state.
