40bae1aea0 drm/amd/display: Move mcache allocation programming from DML to resource
[Why]
mcache allocation programming is not part of DML's core responsibilities.
Keeping this logic in DML leads to poor separation of concerns and complicates maintenance.

[How]
Refactored code to move mcache parameter preparation and mcache ID assignment
into the resource file.

b40d022ec0 drm/amd/display: pass calculated dram_speed_mts to dml2
[why]
currently dml2 is using a hard coded 16 to convert memclk to dram_speed_mts.
for apu, this depends on wck_ratio.

change to pass the already calculated dram_speed_mts from fpu to dml2.

v2: use existing calculation of dram_speed_mts for now to avoid regression

b8dc6ca028 drm/amd/display: Force enable 3DLUT DMA check for dcn401 in DML
[WHY]
Currently TR0 (trip 0) is not properly budgeting for urgent latency in
DML2.1. This results in overly aggressive prefetch schedules that are
vulnerable to request return jitter, resulting in severe underflow at
the start of the frame.

[HOW]
Forcing 3DLUT DMA check to enable causes urgent latency to be budgeted
properly into the prefetch schedule, avoiding the vulnerability.

871512e36f drm/amd/display: Add workaround to restrict max frac urgent for DPM0
[WHY]
Underflow occurs on some platforms when urgent BW is close to
the maximum in DPM0.

[HOW]
It does not occur at DPM1, so as a workaround restrict the maximum
amount and increase the lowest state index for clock states until
we're out of DPM0.
Adds DML2 config options to specify this pe platform as required.

e779f4587f drm/amd/display: Add handling for DC power mode
[Why]
Future implementations will require a distinction between AC power and
DC power (wall power and battery power, respectively). To accomplish this,
adding a power mode parameter to certain dc interfaces, and adding a
separate DML2 instance for DC mode validation. Default behaviour unchanged.

cc263c3a0c drm/amd/display: remove context->dml2 dependency from DML21 wrapper
[Why]
When the DML2 wrapper explicitly accesses context->dml2, that creates a
dependency on where dc saves the DML object. This dependency makes it
harder to have multiple co-existing DML objects, which we would like to
have for upcoming functionality.

[How]
 - make all DML21 interfaces take in a DML2 object as parameter
 - remove all references to context->dml2, use parameter instead

62297b71a0 drm/amd/display: optimize dml2 pipe resource allocation order
[why]
There could be cases that we are transition from MPC to ODM combine.
In this case if we map pipes before unmapping MPC pipes, we might
temporarly run out of pipes. The change reorders pipe resource
allocation. So we unmapping pipes before mapping new pipes.

012a04b1d6 drm/amd/display: Refactor phantom resource allocation
[WHY?]
Phantom streams and planes were previously not referenced explcitly on creation.

[HOW?]
To reduce memory management complexity, add an additional phantom streams and planes
reference into dc_state, and move mall_stream_config to stream_status inside
the state to make it safe to modify in shallow copies. Also consildates any logic
that is affected by this change to dc_state.

7966f319c6 drm/amd/display: Introduce DML2
DC is transitioning from DML to DML2, and this commit introduces all the
required changes for some of the already available ASICs and adds the
required code infra to support new ASICs under DML2. DML2 is also a
generated code that provides better mode verification and programming
models for software/hardware, and it enables a better way to create
validation tools. This version is more like a middle step to the
complete transition to the DML2 version.

Changes since V1:
- Alex: Fix typos

Changes since V2:
- Update DC includes

Changes since V3:
- Fix 32 bit compilation issues on x86

Changes since V4:
- Avoid compilation of DML2 on some not supported 32-bit architecture
- Update commit message
