4b6b7437b1 drm/amd/display: Enable fp16 also on DCE-8/10/11.
The hw supports fp16, this is not only useful for HDR,
but also for standard dynamic range displays, because
it allows to get more precise color reproduction with
about 11 - 12 bpc linear precision in the unorm range
0.0 - 1.0.

Working fp16 scanout+display (and HDR over HDMI) was
verified on a DCE-8 asic, so i assume that the more
recent DCE-10/11 will work equally well, now that
format-specific plane scaling constraints are properly
enforced, e.g., the inability of fp16 to scale on older
hw like DCE-8 to DCE-11.

079204508e drm/amd/display: Check link_active instead of lane_settings != unknown
[Why]
enable_link_dp_mst checks that cur_link_settings != unknown to determine
that the link is already enabled, to skip redundant enablement calls for
multiple streams on the same link. During dc_reinitialize_hardware,
cur_link_settings on previously-active links is not cleared, which blocks
MST links from being re-enabled after a reinitialization.

[How]
 - check for link_status->link_active instead, as it's the real intent
 - clear cur_link_settings when we clear link_active

d1ebfdd8d0 drm/amd/display: Unify psr feature flags

As it stands, psr has feature flags in dm, stream, and link. Most are
not defined well enough, and different dm layers have different uses for
these same flags.

We define a new structure called psr_settings in dc_link that will hold
the following psr feature flags:

psr_feature_enable - psr is supported
psr_allow_active - psr is currently active
psr_version - internal psr version supported
psr_frame_capture_indication_req
psr_sdp_transmit_line_num_deadline
The last two flags were moved out of the power module
for the purposes of consolidating psr flags.
Their use is already well-defined.

Psr caps reported by sink will also be stored in dc_link,
in dpcd_caps.psr_caps.

033baeeefb 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.

03a4059b8d drm/amd/display: Fix incorrect cursor pos on scaled primary plane
[Why]
Cursor pos is correctly adjusted from DC side for source rect offset
on DCN ASIC, but only on the overlay.

This is because DM places offsets the cursor for primary planes only
to workaround missing code in DCE for the adjustment we're now correctly
doing in DC for DCN ASIC.

[How]
Drop the adjustment for source rect from the DM side of things and put
the code where it actually belongs - in DC on the pipe level.

This matches what we do for DCN now.

1da37801a8 drm/amd/display: Drop CONFIG_DRM_AMD_DC_DCN2_0 and DSC_SUPPORTED
[Why]

DCN2 and DSC are stable enough to be build by default. So drop the flags.

[How]

Remove them using the unifdef tool. The following commands were executed
in sequence:

$ find -name '*.c' -exec unifdef -m -DCONFIG_DRM_AMD_DC_DSC_SUPPORT -DCONFIG_DRM_AMD_DC_DCN2_0 -UCONFIG_TRIM_DRM_AMD_DC_DCN2_0 '{}' ';'
$ find -name '*.h' -exec unifdef -m -DCONFIG_DRM_AMD_DC_DSC_SUPPORT -DCONFIG_DRM_AMD_DC_DCN2_0 -UCONFIG_TRIM_DRM_AMD_DC_DCN2_0 '{}' ';'

In addition:

* Remove from kconfig, and replace any dependencies with DCN1_0.
* Remove from any makefiles.
* Fix and cleanup NV defninitions in dal_asic_id.h
* Expand DCN1 ifdef to include DCN2 code in the following files:
    * clk_mgr/clk_mgr.c: dc_clk_mgr_create()
    * core/dc_resources.c: dc_create_resource_pool()
    * dce/dce_dmcu.c: dcn20_*lock_phy()

574304041b drm/amd/display: fix audio endpoint not getting disabled issue
[Why]
Disable_audio_stream gets enum option as a paramenter which will decide
if we free acquired resources or not. However checks for the option is
guarded by the other condition which check if audio stream is getting
diabled more than once. With both conditions combined, if we attempt to
disable audio stream twice in a row, first with keep and second with
free as an option, we will never free any resources, which will make
system think there is audio endpoint connected even after we plug out
the device

of the code that free acquired resources to outside where to keep or to
free resources is actually determined

Currently odm is handled using top_bottom pipe by special casing
the differing opps to differentiate from mpc combine.

Since top/bottom pipe list was made to track mpc muxing this creates
difficulties in adding a 4 pipe odm case support.

Rather than continue using mpc combine list, this change reworks odm
to use it's own linked list to keep track of odm combine pipes. This
also opens up options for using mpo with odm, if a practical use case
is ever found.

3f52aa9f9f drm/amd/display: Set enabled to false at start of audio disable
[Why]
In an effort to stop redundant calls to dce110_disable_audio_stream
the audio->enabled flag was added to the audio resource struct. While
this state probably shouldn't have been tracked on the audio struct
itself it still works fine for some sequences.

However, it does not work for cases where we're freeing the audio
resource (such as hotplugs) or when dynamic audio is enabled.

In these cases the pipe_ctx->stream_res.audio = NULL before we can
set audio->enabled = false. The next time we acquire the audio resource
such as on hotplug the audio will not be enabled for the stream since
DC thinks it's still enabled.

Audio state tracking should cover this sequence.

[How]
Set audio->enabled = false at the start as long as we have
pipe_ctx->stream_res.audio.

[Why]
The AVI infoframe is incorrectly programmed on DCN1/2 when enabling a
stream - causing the wrong pixel encoding to be used for display.

This is because the AVI infoframe is programmed before the DIG BE is
connected to the FE and turned on, so enabling the AFMT block doesn't
actually work and the registers subsequently can't be written to.

[How]
Program the infoframe *after* turning on the DIG FE. This was the
behavior previously used but it was incorrectly reverted
when adding the DCN2 HW sequencer code.

44ab1aa84a drm/amd/display: do not power on eDP power rail early
[Why]
Modern Standby may toggle display adapter state between D0
and D3 state unpredictably.
But events that cause transition to D0 are not always resulting
in a display light up scenario.

Modern eDP panels should be able to power on panel logic
quickly upon VDD going high. Based on spec, the T3 time
between VDD on and HPD high can be between 0 and 80 ms.

Doing any tricky sorts of optimization by powering on panel
VDD early during D0 transition on can negatively impact other
features due to unnecessary power drain and toggling when
final system state does not intend for the panel to be lit up.

We need OEMs to source higher end panels that have T3 time
close to 0 if they want quick S3/Modern Standby resume times.

[How]
Remove panel VDD power on in init_hw

e5c4197090 drm/amd/display: Add plane capabilities to dc_caps
[Why]
The current dc_caps doesn't provide the information needed to
determine the count and type of each plane to be exposed to userspace.

There are three types of DRM planes that are exposed to userspace:

1. Primary planes (can be used for modesetting)
2. Overlay planes (can be blended below or above a primary plane)
3. Cursor planes (blended topmost)

We need to know the number and type of each in amdgpu_dm to expose
to userspace.

Hardware supports blending planes below, above or both ways depending
on the ASIC. Alpha support is also ASIC dependent. Some hardware has
dedicated pipes for overlays and other hardware combines the pipes.

All of this should be exposed in a way that DM can query and use.

[How]
Introduce the dc_plane_cap structure that describes the capabilities
for the hw planes.

It describes:
- the type of the plane
- whether the plane can blend with planes below it
- whether the plane can blend with planes above it
- whether the plane supports per pixel alpha blending
- supported formats on the plane (partial list for now)

Pre DCN ASICs don't have their full capabilities described for now.
They can be updated as needed in the future.
