b2a7b0ce07 drm/amd/display: Use cursor locking to prevent flip delays
[Why]
Current locking scheme for cursor can result in a flip missing
its vsync, deferring it for one or more vsyncs.  Result is a
potential for stuttering when cursor is moved.

[How]
Use cursor update lock so that flips are not blocked while cursor
is being programmed.

d243b6ffde drm/amd/display: Make cursor source translation adjustment optional
[Why]
In some usecases, like tiled display, the stream and plane configuration
can be setup in a way where the caller expects DAL to perform the
clipping, eg:

P0:
src_rect(0, 0, w, h)
dst_rect(0, 0, w, h)

P1:
src_rect(w, 0, w, h)
dst_rect(0, 0, w, h)

Cursor is enabled on both streams with the same position.

This can result in double cursor on tiled display, even though this
behavior is technically correct from the DC interface point of view.

We need a mechanism to control this dynamically.

[How]
This is something that should live in the DM layer based on detection
of the specified configuration but it's not something that we really
have enough information to deal with today.

Add a flag to the cursor position state that specifies whether we
want DC to do the translation or not and make it opt-in and let
the DM decide when to do it.

e99acf7d1a drm/amd/display: Translate cursor position by source rect
[Why]
Cursor is drawn as part of the framebuffer for a plane on AMD hardware.
The cursor position on the framebuffer does not change even if the
source rect viewport for the cursor does. This causes the cursor to be
clipped.

The following IGT tests fail as a result of this issue:

- kms_plane_cursor@pipe-*-viewport-size-*

[How]
Offset cursor position by plane source rect viewport. If the viewport
is unscaled then the cursor is now correctly positioned on any
plane - primary or overlay.

There is still a hardware limitation for dealing with the cursor size
being incorrectly scaled but that's not something we can address.

Add some documentation explaining some of this in the code while we're
at it.

8d8c82b699 drm/amd/display: add worst case dcc meta pitch to fake plane
[why]
When we have single channel memory, we can not light up 2 4k displays
with a 1080p edp, because we don't have enough bw by a small margin.
this small margin comes from dcc meta being too large. We however don't
have this dcc meta when we create fake planes so, before the flip we
will not filter out the mode for 2 4k displays with a 1080p edp

[how]
Change get_default_swizzle_mode to something more general so we don't
end up with a separate function for every missing field in the fake
plane. Add a reasonable dcc meta to the fake plane when it is filled in,
so we filter out modes that don't have enough bandwidth. To do this, we
take the screen width and align it to 1024(8k 60)

c6a228be7f drm/amd/display: Only enable cursor on pipes that need it
[Why]
In current code we're essentially drawing the cursor on every pipe
that contains it. This only works when the planes have the same
scaling for src to dest rect, otherwise we'll get "double cursor" where
one cursor is incorrectly filtered and offset from the real position.

[How]
Without dedicated cursor planes on DCN we require at least one pipe
that matches the scaling of the current timing.

This is an optimization and workaround for the most common case where
the top-most plane is not scaled but the bottom-most plane is scaled.

Whenever a pipe has a parent pipe in the blending tree whose recout
fully contains the current pipe we can disable the pipe.

This only applies when the pipe is actually visible of course.

5b5abe9526 drm/amd/display: make PSR static screen entry within 30 ms
[Why]
With different refresh rate panels, the PSR entry/exit time is
different since it is dependent on 2 frame entry time today

[How]
Make static screen num frame entry time to be calculated
such that entry time is within 30 ms instead of fixed num
frames.

d9eb70ae61 drm/amd/display: Fix double buffering in dcn2 ICSC
[Why]
When rapidly adjusting video brightness, screen tearing was observed.
This was due to overwritten values in ICSC registers. In dcn10, this issue had been
fixed by implementing double buffering via alternating ICSC modes.
However, the second register set used in dcn1 doesn't exist in dcn2.

[How]
Create new program_input_csc for dcn20.
Use ICSC_B registers instead of COMA registers as second set.

6426745427 drm/amd/display: fix missing cursor on some rotated SLS displays
[Why]
Cursor disappears for some SLS displays that are rotated 180
and 270 degrees.  This occurs when there is no pipe split being
done ( ex. 3 or more displays ).  The cursor calculations assume
pipe splitting is done so when it calculates the new cursor
position in hwss.set_cursor_position(), it is out-of-bounds so
it disables the cursor in hubp.set_cursor_position().

[How]
In non pipe split cases, calculate cursor using viewport size
( width or height ) instead of viewport size * 2 ( the two
because pipe splitting divides the rectangle into two ).

1380c1bf5b drm/amd/display: Remove reliance on pipe indexing
[Why]
In certain instances, there was a reliance on pipe indexing being accurate. However, this
assumption fails with harvesting of pipes 1 or 2, which can occur in production B6 parts.
HW hang would occur as a result.

[How]
Use hubp index for mpcc, and do mpc_init for all theoretical pipes (including disabled ones).

[Why]
1. Set second screen only then unplug external monitor
2. Enter to S4 then plug in external monitor
3. Resume from S4, eDP will not turn off when OS set
   second screen only
Sometimes OS will not set eDP power up cause eDP dpms_off

1ba2a48305 drm/amd/display: Disable chroma viewport w/a when rotated 180 degrees
[WHY]
Previous Renoir chroma viewport workaround fixed an MPO flicker by
increasing the chroma viewport size. However, when the MPO plane is
rotated 180 degrees, the viewport is read in reverse. Since the workaround
increases viewport size, when reading in reverse it causes a vertical
chroma offset.

[HOW]
Pass rotation value to viewport set functions
Temporarily disable the chroma viewport w/a when hubp is rotated 180 degrees

f42ea55be1 drm/amd/display: add separate of private hwss functions
[Why]
Some function pointers in the hwss function pointer table are
meant to be hw sequencer entry points to be called from dc.

However some of those function pointers are not meant to
be entry points, but instead used as a code reuse/inheritance
tool called directly by other hwss functions, not by dc.

Therefore, we want a more clear separation of which functions
we determine to be interface functions vs the functions we
use within hwss.

[How]
DC interface functions will be stored in:
    struct hw_sequencer_funcs
Functions used within HWSS will be stored in:
    struct hwseq_private_funcs
