d5b5d6cb1d drm/amd/display: Create debugging mechanism for Gaming FAMS
[WHY]
To enable FAMS even during gaming sessions.

[HOW]
By leveraging a new dc.debug parameter.

27fc10d109 drm/amd/display: Fix the delta clamping for shaper LUT
The shaper LUT requires a 10-bit value of the delta between segments. We
were using dc_fixpt_clamp_u0d10() to do that but it doesn't do what we
want it to do. It will preserve 10-bit precision after the decimal
point, but that's not quite what we want. We want 14-bit precision and
discard the 4 most-significant bytes.

To do that we'll do dc_fixpt_clamp_u0d14() & 0x3ff instead.

ce560ac402 drm/amd/display: Block optimize on consecutive FAMS enables
[WHY]
It is possible to commit state multiple times in rapid succession with
FAMS enabled; if each of these commits were to set optimized_required,
then the user may see latency.

[HOW]
fw_based_mclk_switching is currently not used in dc->clk_mgr; use it
to track whether the current state has FAMS enabled;
if it has, then do not disable FAMS in prepare_bandwidth, and do not set
optimized_required.

474f01015f drm/amd/display: Do not set drr on pipe commit
[WHY]
Writing to DRR registers such as OTG_V_TOTAL_MIN on the same frame as a
pipe commit can cause underflow.

[HOW]
Move DMUB p-state delegate into optimze_bandwidth; enabling FAMS sets
optimized_required.

This change expects that Freesync requests are blocked when
optimized_required is true.

To ensure that FAMS can be used, DC must check if there is VRR support.
This commit adds the required configuration to ensure FAMS can be executed in the target system.

e97cc04fe0 drm/amd/display: refactor dmub commands into single function
[Why & How]
Consolidate dmub access to a single interface. This makes it easier to
add code in the future that needs to run every time a dmub command is
requested (e.g. instrumentation, locking etc).

751e171479 drm/amd/display: Block optimize on consecutive FAMS enables
[WHY]
It is possible to commit state multiple times in rapid succession with
FAMS enabled; if each of these commits were to set optimized_required,
then the user may see latency.

[HOW]
fw_based_mclk_switching is currently not used in dc->clk_mgr; use it
to track whether the current state has FAMS enabled;
if it has, then do not disable FAMS in prepare_bandwidth, and do not set
optimized_required.

[WHY]
Writing to DRR registers such as OTG_V_TOTAL_MIN on the same frame as a
pipe commit can cause underflow.

[HOW]
Move DMUB p-state delegate into optimze_bandwidth; enabling FAMS sets
optimized_required.

This change expects that Freesync requests are blocked when
optimized_required is true.

37403ced9f drm/amd/display: fixed dcn30+ underflow issue
[Why]
Observing underflow on dcn30+ system config at 4k144hz

[How]
We set the UCLK hardmax on AC/DC switch if softmax is enabled
and also on boot. While booting up the UCLK Hardmax is set
to softmax before the init sequence and the init sequence
resets the hardmax to UCLK max which enables P-state switching.
Just added a conditional check to avoid setting hardmax on init.

98ce7d32e2 drm/amd/display: convert link.h functions to function pointer style
[Why & How]
All dc subcomponents should call another dc component via function pointers
stored in a component structure. This is part of dc coding convention since
the beginning. The reason behind this is to improve encapsulation and
polymorphism. The function contract is extracted into a single link service
structure defined in link.h header file and implemented only in link_factory.c instead
of spreading across multiple files in link component file structure.

c0a76ae874 drm/amd/display: remove legacy fields of dc_plane_cap struct
The fields blends_with_above and blends_with_below of struct
dc_plane_cap (defined in dc/dc.h) are boolean and set to true by
default. All instances of a dc_plane_cap maintain the default values of
both. Also, there is only one if statement that checks those fields and
there would be the same effect if it was deleted (assuming that those
fields are always going to be true).

For this reason, considering both fields as legacy ones, this commit
removes them and the aforementioned if statement.
