[Why]
As long as we have at least one non-cursor plane enabled on a CRTC then
the CRTC itself can remain enabled.
This will allow for commits where there's an overlay plane enabled but
no primary plane enabled.
[How]
Remove existing primary plane fb != NULL checks and replace them with
the new does_crtc_have_active_plane helper.
This will be called from atomic check when validating the CRTC.
Since the primary plane state can now potentially be NULL we'll need
to guard for that when accessing it in some of the cursor logic.

[Why]
Surface scaling info updates can affect bandwidth and blocks. We need
to be checking these with global validation to avoid underflow or
corruption.
[How]
Drop the state->allow_modeset early exit in
dm_determine_update_type_for_commit. Most of those should be considered
fast now anyway.
Fill in scaling info and it to the surface update in atomic
check.

[Why]
DM thinks that the update type should be full whenever a stream or
plane is added or removed (including recreations).
This won't match in the case where DC thinks what looks like a fast
update to DM is actually a medium or full - like scaling changes that
affect bandwidth and clocks.
[How]
Drop this warning. DC knows better than the DM does for determining
cases like this.
The other warning can be kept for now since it would warn on a pretty
serious DC or DM bug.

[Why]
DC expects the surface memory address to identify the surface.
This doesn't work with what we're doing with the temporary surfaces,
it will always assume this is a full update because the surface
isn't in the current context.
[How]
Use the surface directly. This doesn't give us much improvement yet,
since we always create a new dc_plane_state when state->allow_modeset
is true.
The call into dc_check_update_surfaces_for_stream also needs to be
locked, for two reasons:
1. It checks the current DC state
2. It modifies the surface update flags
Both of which could be currently in the middle of commit work from
commit tail.
A TODO here is to pass the context explicitly into this function and
find a way to get the surface update flags out of it without modifying
the surface in place.

[Why]
Planes have downscaling limits and upscaling limits per format and DM
is expected to validate these using DC caps. We should fail atomic
check validation if we aren't capable of doing the scaling.
[How]
We don't currently create store which DC plane maps to which DRM plane
so we can't easily check the caps directly. For now add basic
constraints that cover the absolute min and max downscale / upscale
limits for most RGB and YUV formats across ASICs.
Leave a TODO indicating that these should really be done with DC caps.
We'll probably need to subclass DRM planes again in order to correctly
identify which DC plane maps to it.

[Why]
We currently don't do DC validation for medium or full updates where
the plane state isn't created. There are some medium and full updates
that can cause bandwidth or clock changes to occur resulting in
underflow or corruption.
We need to be able to fill surface and plane info updates during
atomic commit for dm_determine_update_type for commit. Since we already
do this during atomic commit tail it would be good if we had the same
logic in both places for creating these structures.
[How]
Introduce fill_dc_scaling_info and fill_dc_plane_info_and_addr.
These two functions cover the following three update structures:
- struct dc_scaling_info
- struct dc_plane_info
- struct dc_plane_address
Cleanup and adapter the existing fill_plane_* helpers to work with
these functions.
Update call sites that used most of these sub helpers directly to work
with the new functions. The exception being prepare_fb - we just want
the new buffer attributes specifically in the case where we're
creating the plane. This is needed for dc_commit_state in the case
where the FB hasn't been previously been used.
This isn't quite a refactor, but functionally driver behavior should
be mostly the smae as before. The one exception is that we now check
the return code for fill_plane_buffer_attributes which means that
commits will be rejected that try to enable DCC with erroneous
parameters.

[Why]
Pitch was only calculated based on format whenever the plane state
was recreated. This could result in surface corruption due to the
incorrect pitch being programmed when the surface pitch changed during
commits where state->allow_modeset = false.
[How]
Recalculate pitch at the same time we update the buffer address and
other buffer attributes. This function was previously called
fill_plane_tiling_attributes but I've also renamed it to
fill_plane_buffer_attributes to clarify the actual intent of the
function now that it's handling most buffer related attributes.

[Why]
The overlay will be incorrectly placed *below* the primary plane for
commits with state->allow_modeset = true because the primary plane
won't be removed and recreated in the same commit.
[How]
Add the should_reset_plane helper to determine if the plane should be
reset or not. If we need to add or force reset any plane in the context
then we'll need to do the same for every plane on the stream.
Unfortunately we need to do the remove / recreate routine for removing
planes as well since DC currently isn't well equipped to handle the
plane with the top pipe being removed with other planes still active.

[Why]
Plane scaling parameters are not correctly filled or updated when
performing fast updates.
They're filled when creating the dc plane state and during atomic check.
While the atomic check code path happens for the plane even during fast
updates, the issue is that they're done in place on the dc_plane_state
directly. This dc_plane_state may be the current state plane state
being used by the hardware, so these parameters won't be correctly
programmed.
The new scaling parameters should instead be passed as an update
to the plane.
[How]
Update fill_rects_from_plane_state to not modify dc_plane_state
directly. Update the call sites that use this to fill in the appropriate
values.

[Why]
When entering S3, amdgpu first calls DRM to cache the current atomic
state, then commit the 'all-disabled' state. This sets dc->current_state
to point at the private atomic object's dm_atomic_state->context, as
any regular atomic commit would.
Afterwards, amdgpu_dm calls dc_set_power_state() with S3 power state.
This invalidates dc->current_state by wiping it to 0, consequently
wiping dm_atomic_state->context.
During resume, the cached atomic state is restored. When getting the
private object however, the dm_atomic_state - containing the wiped
context - is duplicated into the atomic state. This causes DC validation
to fail during atomic check, as necessary function pointers in dc_state
are now NULL.
[How]
Recreate the private object's dm_atomic_state->context during resume,
restoring any static values such as function pointers.
A TODO item is added to move static read-only values out of dc_state -
they shouldn't be there anyways.

If link is already enabled at a different rate (for example 5.4 Gbps)
then calling VBIOS command table to switch to a new rate

This can lead to link training failure to occur.
[How]
If the requested link rate is different than the current link rate,
the link must be disabled in order to re-enable at the new
link rate.
In today's logic it is currently only impacting eDP since DP
connection types will always disable the link during display

The brace initialization used here generates warnings on some
compilers. For example, on GCC 4.9:
[...] In function ‘dm_determine_update_type_for_commit’:
[...] error: missing braces around initializer [-Werror=missing-braces]
struct dc_stream_update stream_update = { 0 };
^
Use memset to make this more portable.
v2: Specify the compiler / diagnostic in the commit message (Paul)

Under vega10 virtualuzation, smu ip block will not be added.
Therefore, we need add pp clk query and force dpm level function
at amdgpu_virt_ops to support the feature.
v2: add get_pp_clk existence check and use kzalloc to allocate buf
v3: return -ENOMEM for allocation failure and correct the coding style
