drm/amd/display: do not treat clip_rect size change as a scaling change
[why]
With previous ODM + MPO policy we will only allocate pipes when MPO plane
has intersection with current ODM slice. With this policy we have to indicate
scaling change when plane clip is updated in case plane clip change causes
MPO plane to go in or out current ODM slice.
With new ODM + MPO policy we allocate pipe independent from plane clip size
so we no longer treat it as a scaling change. There no need to do a full update
due to clip size change anymore.

Preivous algorithm for finding an optimal idle pipe for a new plane was

it no longer depends on the MPO plane's position. We are simplifying

drm/amd/display: always acquire MPO pipe for every blending tree
[why]
We only acquire MPO pipe for blending tree where the plane clip will
be rendered. If an MPO plane is outside current ODM slice rect, we will
skip pipe allocation. With new programming policy we want to allocate
pipes for every ODM slice blending tree even for those whose ODM slice
rect doesn't intersect with plane clip. This is aligned with DML validation
so the pipe topology is programmed independently from the plane's
position and dst plane size.
[how]
- Remove the logic to allocate pipe only when the MPO plane intersects
with ODM slice and replace with the new logic to always allocate pipes.
- Remove the logic to tear down ODM configuration in favor for supporting
secondary MPO planes.
- Remove the logic to use full update when MPO goes accross ODM slice

drm/amd/display: support plane clip with zero recout size
[why]
If plane clip is outside current pipe's ODM slice rect, our logic will
fail validation because we assume that when a pipe is acquired
to support a plane clip, it must blend some portion of the plane
on the screen. This assumption needs to be changed.
When a pipe is acquired to render the plane, we are now allowing
it to support a case where it can take minimum viewport and draw
with zero recout size when the plane clip is outside current ODM
slice rect. The reason is that we want to allocate and get the pipe
pre-programmed so it is ready to be rendered when user moves
the plane over to the current ODM slice with a fast update.
Whereas with the existing solution when user moves the plane
over, we will need to allocate a pipe as needed and power it up
and program it through a full update. This not only impacts the
user experience with unnecessary delay of a frame but also
doesn't generate any benefit to the user because DML doesn't
support it. DML will invalidate based on worst case scenario and
it doesn't depend on the plane location. So having our
programming sequence support such dynamic pipe allocation is
not meaningful anyway.
[how]
In build scaler params allow recout to be zero size and if viewport
is smaller than minimum, set minimum viewport size.

drm/amdkfd: Relocate TBA/TMA to opposite side of VM hole
The TBA and TMA, along with an unused IB allocation, reside at low
addresses in the VM address space. A stray VM fault which hits these
pages must be serviced by making their page table entries invalid.
The scheduler depends upon these pages being resident and fails,
preventing a debugger from inspecting the failure state.
By relocating these pages above 47 bits in the VM address space they
can only be reached when bits [63:48] are set to 1. This makes it much
less likely for a misbehaving program to generate accesses to them.
The current placement at VA (PAGE_SIZE*2) is readily hit by a NULL
access with a small offset.

drm/amd/display: Add structs for Freesync Panel Replay
In some instances, the GPU is transmitting repeated frame to the sink
without any updates or changes in the content. These repeat transmission
are wasteful, resulting in power draw in different aspects of the system
1. DCN is fetching the frame of data from DF/UMC/DRAM. This memory traffic
prevents power down of parts of this HW path.
2. GPU is transmitting pixel data to the display through the main link of
the DisplayPort interface. This prevents power down of both the Source
transmitter (TX) and the Sink receiver (RX)
\7f
The concepts of utilizing replay is similar to PSR, but there is a benefit of:
Source and Sink remaining synchronized which allows for
- lower latency when switching from replay to live frames
- enable the possibility of more use cases
- easy control of the sink's refresh rate during replay
Due to Source and Sink remaining timing synchronized, Replay can be activated
in more UI scenarios.

On PSP v13.x ASICs, boot loader will set only the MSB to 1 and clear the
least significant bits for any command submission. Hence match against
the exact register value, otherwise a register value of all 0xFFs also
could falsely indicate that boot loader is ready. Also, from PSP v13.0.6

drm/amd: Disable S/G for APUs when 64GB or more host memory
Users report a white flickering screen on multiple systems that
is tied to having 64GB or more memory. When S/G is enabled pages
will get pinned to both VRAM carve out and system RAM leading to
this.
Until it can be fixed properly, disable S/G when 64GB of memory or
more is detected. This will force pages to be pinned into VRAM.
This should fix white screen flickers but if VRAM pressure is
encountered may lead to black screens. It's a trade-off for now.

drm/panel: Fix todo indentation for panel prepared/enabled cleanup
In commit
d2aacaf07395 ("drm/panel: Check for already prepared/enabled

right. This caused an error when building htmldocs:

drm/i915/guc/slpc: Restore efficient freq earlier
This should be done before the soft min/max frequencies are restored.
When we disable the "Ignore efficient frequency" flag, GuC does not
actually bring the requested freq down to RPn.
Specifically, this scenario-
- ignore efficient freq set to true
- reduce min to RPn (from efficient)
- suspend
- resume (includes GuC load, restore soft min/max, restore efficient freq)
- validate min freq has been resored to RPn
This will fail if we didn't first restore(disable, in this case) efficient
freq flag before setting the soft min frequency.
v2: Bring the min freq down to RPn when we disable efficient freq (Rodrigo)
Also made the change to set the min softlimit to RPn at init. Otherwise, we
were storing RPe there.
