12 months agodrm/amd/display: update add plane to context logic with a new algorithm
Wenjing Liu [Sat, 22 Jul 2023 19:45:00 +0000 (15:45 -0400)]
drm/amd/display: update add plane to context logic with a new algorithm

[why]
Preivous algorithm for finding an optimal idle pipe for a new plane was
implemented to handle dynamic pipe allocation when MPO plane moves
from one ODM slice to the other. Now pipe allocation is more static so
it no longer depends on the MPO plane's position. We are simplifying
our logic and remove unnecessary handling in our code.

[how]
Apply a new simplified version of pipe resource allocation logic to reduce
unnecessary flip delay caused by swapping secondary dpp pipe to other
MPC blending tree.

12 months agodrm/amd/display: always acquire MPO pipe for every blending tree
Wenjing Liu [Thu, 20 Jul 2023 16:30:29 +0000 (12:30 -0400)]
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
boundary.

12 months agodrm/amd/display: support plane clip with zero recout size
Wenjing Liu [Thu, 20 Jul 2023 15:47:55 +0000 (11:47 -0400)]
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.

12 months agodrm/amd/display: Add structs for Freesync Panel Replay
Bhawanpreet Lakha [Fri, 12 May 2023 18:03:15 +0000 (14:03 -0400)]
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.

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)

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)

drm/i915: Remove unnecessary include

The inclusion of intel_gt_defines.h was initially added to
i915_drv.h to provide the definition of I915_MAX_GT, where it was
originally defined.

However, since I915_MAX_GT is now included in
i915_gem_object_types.h, it sis no longer required in i915_drv.h.
