d61e4ba33e drm/amd/display: do not change pipe split policy for RV2
[Why]
RV2 do not change pipe split policy in the
minimal pipe split transition state.
This will unblock mode support on some
parts that limit to DPM0 for power reason.

[How]
Do not change pipe split policy in the
minimal pipe split transition state to
allow 4k multi display configs to be
supported at DPM0.

0a8c91d7b6 drm/amd/display: include soc._clock_tmp[] into DC's scratch region
Currently, we are using soc._clock_tmp[] to temporarily store and modify
data from soc.clock_limits[] before copying it back into
soc.clock_limits[] (because modifying data directly in
soc.clock_limits[] causes unintended behavior). However, this approach
has a number of downsides, such as:

	1. struct _vcs_dpi_soc_bounding_box_st's creation/destruction
	   aren't well defined (which could mean more unintended
	   behavior).
	2. Throwing "temp" varibles in structs everywhere doesn't make
	   for a particularly readable codebase.

For these reasons, we should get rid of soc._clock_tmp[] by defining a
struct scratch within struct dc that, contains within it all of the
temporary variables (including _clock_tmp[]) such that it is obvious how
they are intended to be used.

e5028e9fd3 drm/amd/display: Add DCN reg offsets to DC
[Why&How]
Add a field to store the DCN IP offset for use with runtime offset
calculation

This offset is indexed using reg*_BASE_IDX for the corresponding
group of registers. For example, address of DIG_BE_CNTL instance 0 is
calculated like: dcn_reg_offsets[regDIG0_DIG_BE_CNTL_BASE_IDX] +
regDIG0_DIG_BE_CNTL.

{dcn,nbio}_reg_offsets are used only for the ASICs for which runtime
initializaion of offsets are enabled through the modified SR* macros
that contain an additional REG_STRUCT element in the macro definition.

DCN3.5+ will fail dc_create() if {dcn,nbio}_reg_offsets are null. They
are applicable starting with DCN32/321 and are not used for ASICs
upstreamed before them. ASICs before DCN32/321 will not contain any
computation that involves {dcn,nbio}_reg_offsets. For them, the
address/offset computation is done during compile time.

This is evident from the BASE_INNER definition for compile time vs run
time initialization:

Compile time init: #define BASE_INNER(seg) DCN_BASE__INST0_SEG ## seg
Run time init:     #define BASE_INNER(seg) ctx->dcn_reg_offsets[seg]

BASE_INNER macro is local to each dcnxx_resource.c and hence different
ASICs can have either runtime or compile time initialization of offsets.

The computation of offset is done for registers all at once during
driver load and hence it does not introduce any performance overhead
during normal operation.

14eb72ff58 drm/amd/display: Exit SubVP if MPO in use
[Description]
Exit SubVP if MPO is in use since SubVP + MPO together is not supported.
- Don't add SubVP at validation time if we see MPO is in use

Issues fixed in the SubVP / MPO transition:
1. Enable phantom pipes in post unlock function to prevent underflow
when an active pipe is being transitioned to be a phantom pipe (VTG
updates take place right away). Also must wait for VUPDATE of the main
pipe to complete first

2. Don't wait for MPCC idle when transitioning a phantom pipe to an
actual pipe. MPCC_STATUS is never asserted due to OTG being off for
phantom pipes

3. When transitioning an active pipe to phantom, program DET right away
(same as disabling the pipe) or the DET update will only take when
the phantom pipe is enabled which can cause DET allocation errors.

4. For K1/K2 programming of phantom pipes, use same settings as the
main pipe. Also don't program K1 / K2 = 0xF ever since the field is only
1 / 2 bits wide.

88ef4c5bb3 drm/amd/display: Apply ODM 2:1 policy for single display configuration
[Why]
Most of the time, a single display uses the ODM combine. When using
multi-display, we use ODM combine only if it is necessary. These cases
are not flexible enough for us, and we can improve them to take
advantage of our hardware. We want to have more control over the ODM
policy.

[How]
This commit add a new debug flag named
enable_single_display_2to1_odm_policy to control the ODM policy and
another flag named enable_dp_dig_pixel_rate_div_policy to fine control
the ODM combine. This is possible by adding a new "pipe.dest" parameter
that can be set to ODM 2:1 combined if we use a single display. For
dynamic ODM combine, when using DP-DIG, DCN applies K2=2 settings for
ODM combine. Note that this feature affects the following registers:

- timing.pix_clk_100khz -> DP_VID_M, DP_VID_N
- requested_pix_clk_100hz -> DP_DTOn_PHASE
- OTGn_PIXEL_RATE_DIVK2
- DP_PIXEL_PER_CYCLE_PROCESSING_MODE
- DIG_FIFO_OUTPUT_PIXEL_MODE
- DP_VID_N_MUL

06f2f7772d drm/amd/display: Fix eDP not light up on resume
[why]
Only on VG, if external display is disconnected during S3 suspend, the
internal panel doesn't light up on resume because we set the power state
using an unsupported DPCD register SET_POWER.  To check the register is
supported, we need to check SET_POWER_CAPABLE first which is
eDP-specific DPCD register field.

[how]
Check the SET_POWER_CAPABLE register field and decide the control of the
eDP power state based on the read register value.

ba8b460445 drm/amd/display: Blank for uclk OC in dm instead of dc
[Why]
All displays need to be blanked during the uclk OC interface so that we can
guarantee pstate switching support. If the display config doesn't support
pstate switching, only using core_link_disable_stream will not enable it
as the front-end is untouched. We need to go through the full plane removal
sequence to properly program the pipe to allow pstate switching.

[How]
 - guard clk_mgr functions with non-NULL checks

2d017189e2 drm/amd/display: Blank eDP on enable drv if odm enabled
[Why]
For panels with pixel clock > 1200MHz that require ODM
in pre-OS, when driver is disabled in OS, odm is enabled.
Upon driver enablement, corruption is seen if
odm was originally enabled. DP_PIXEL_COMBINE and
pixelclk must be programmed prior to programming the
optc-odm registers. However, eDP displays aren't blanked
prior to initializing odm in this case.

[How]
Upon driver enablement, check whether odm is enabled,
if so, blank eDP prior to programming optc-odm
registers.

76818cdd11 drm/amd/display: add Coverage blend mode for overlay plane
According to the KMS man page, there is a
"Coverage" alpha blend mode that assumes the
pixel color values have NOT been pre-multiplied
and will be done when the actual blending to
the background color values happens.

Previously, this mode hasn't been enabled
in our driver and it was assumed that all
normal overlay planes are pre-multiplied
by default.

When a 3rd party app is used to input a image
in a specific format, e.g. PNG, as a source
of a overlay plane to blend with the background
primary plane, the pixel color values are not
pre-multiplied. So by adding "Coverage" blend
mode, our driver will support those cases.

Issue fixed: Overlay plane alpha channel blending is incorrect
Issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/1769

Reference:
https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties

Adding Coverage support also enables IGT
kms_plane_alpha_blend Coverage subtests:
1. coverage-7efc
2. coverage-vs-premult-vs-constant

Changes
1. Add DRM_MODE_BLEND_COVERAGE blend mode capability
2. Add "pre_multiplied_alpha" flag for Coverage case
3. Read the correct flag and set the DCN MPCC
pre_multiplied register bit (only on overlay plane)
