Currently the paremeters are extracted as if dml is calculating
using pipes as we pass them in. in reality, dml internally merges
pipes into planes if pipe split is detected.
This change adds reverse logic to dcn20_calculate_dlg_params so
that the global sync parameters can be correctly extracted for
all the pipes when pipe split is enabled.

These are needed to send back DRM vblank events in the case where VRR

[Why]
There are currently two interfaces for exactly the same thing:
hupb_update_dchub in hupb and update_dchub in hubbub. The hubbub
version is currently unused past dcn10, largely because the call
from the dcn10 hardware sequencer does not call through the
interface, so the hupb interface was used instead. This is
confusing because of the duplicate code, the unused functions,
and the fact that more that one block currently owns this set
of registers.
[How]
Remove the hubp interface entirely, as well as the register
declarations that are not longer needed because of this. Change
the call site to always call the hubbub version through the
interface. Fix the update_dchub function in dcn20_hubbub.c to
program the correct registers for dcn20.

Resource mapping done in dcn20_validate_bandwidth has a flaw: When a full
update is performed, the HWSS will only update the MPCC tree for the stream
that is updated as opposed to all streams. This means that when mapping pipes
in validation, care must be taken to not change any existing mapping, otherwise it
leads to partial hw programming
[how]
it's not strictly necessary to track which stream/mpcc tree is being updated, but
rather it's sufficient to compare current and new state and just keep pipes that were
previously already mapped unchanged.

At the time DIG FE is connected to its BE, the clocks in OTG are enabled and
PHY will also be set up. When DSC has to be used to fit the stream into the
available bandwidth, without DSC being set DIG could get exposed to the
higer bandwidth it (or link) could handle. This causes the HW to "reject"
video enable setup (the register shows that video enable was attempted, but
the status bit shows it as disabled).
[how]
- Separate DSC setup into DSC register config and DSC PPS SDP setup
- Move most of the DSC setup (register config) to before
dcn10_link_encoder_connect_dig_be_to_fe() is called
- Set up DSC PPS SDP after DIG FE is connected to its BE. This is because
setting DSC PPS SDP before that has no effect.

However, before the VUPDATE occurs, DM may call with an "immediate" flip which is address

[why]
DC does not correct account for the fact that DPP DTO is double buffered while DPP ref is not.
This means that when DPP ref clock is lowered when it's "safe to lower", the DPP blocks that need
an increased divider will temporarily have actual DPP clock drop below minimum while DTO
double buffering takes effect. This results in temporary underflow.
[how]
To fix this, DPP clock cannot be programmed atomically, but rather be broken up into the DTO and the
ref. Each has a separate "safe to lower" logic. When doing "prepare" the ref and dividers may only increase.
When doing "optimize", both may decrease. It is guaranteed that we won't exceed max DPP clock because
we do not use dividers larger than 1.

[Why]
Underflow can occur in the case where we change buffer pitch, DCC state,
rotation or mirroring for a plane while also performing an immediate
flip. It can also generate a p-state warning stack trace on DCN1 which
is typically observed during the cursor handler pipe locking because of
how frequent cursor updates can occur.
[How]
Store the update type on each CRTC - every plane will have access to
the CRTC state if it's flipping. If the update type is not
UPDATE_TYPE_FAST then the immediate flip should be disallowed.
No changes to the target vblank sequencing need to be done, we just
need to ensure that the surface registers do a double buffered update.

[Why]
Pitch, DCC, rotation and mirroring can result in updates that are not
UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info
and dc_plane_size to make this determination and we aren't currently
passing this into DC during atomic check.
Underflow (visible or non-visible) can occur if we don't validate this
correctly. This also will generally trigger p-state warnings, typically
via the cursor handler when locking.
[How]
Get the framebuffer tiling flags and generate the required structures
for DC in dm_determine_update_type_for_commit.

[Why]
DRM private objects have no hw_done/flip_done fencing mechanism on their
own and cannot be used to sequence commits accordingly.
When issuing commits that don't touch the same set of hardware resources
like page-flips on different CRTCs we can run into the issue below
because of this:
1. Client requests non-blocking Commit #1, has a new dc_state #1,
state is swapped, commit tail is deferred to work queue
2. Client requests non-blocking Commit #2, has a new dc_state #2,
state is swapped, commit tail is deferred to work queue
3. Commit #2 work starts, commit tail finishes,
atomic state is cleared, dc_state #1 is freed
4. Commit #1 work starts,
commit tail encounters null pointer deref on dc_state #1
In order to change the DC state as in the private object we need to
ensure that we wait for all outstanding commits to finish and that
any other pending commits must wait for the current one to finish as
well.
We do this for MEDIUM and FULL updates. But not for FAST updates, nor
would we want to since it would cause stuttering from the delays.
FAST updates that go through dm_determine_update_type_for_commit always
create a new dc_state and lock the DRM private object if there are
any changed planes.
We need the old state to validate, but we don't actually need the new
state here.
[How]
If the commit isn't a full update then the use after free can be
resolved by simply discarding the new state entirely and retaining
the existing one instead.
With this change the sequence above can be reexamined. Commit #2 will
still free Commit #1's reference, but before this happens we actually
added an additional reference as part of Commit #2.
If an update comes in during this that needs to change the dc_state
it will need to wait on Commit #1 and Commit #2 to finish. Then it'll
swap the state, finish the work in commit tail and drop the last
reference on Commit #2's dc_state.

[Why]
By passing through the dm_determine_update_type_for_commit for atomic
commits that can be done asynchronously we are incurring a
performance penalty by locking access to the global private object
and holding that access until the end of the programming sequence.
This is also allocating a new large dc_state on every access in addition
to retaining all the references on each stream and plane until the end
of the programming sequence.

Shift the determination for async update before validation. Return early
if it's going to be an async update.

[Why]
We previously allowed framebuffer swaps as async updates for cursor
planes but had to disable them due to a bug in DRM with async update
handling and incorrect ref counting. The check to block framebuffer
swaps has been added to DRM for a while now, so this check is redundant.
The real fix that allows this to properly in DRM has also finally been
merged and is getting backported into stable branches, so dropping
this now seems to be the right time to do so.
[How]
Drop the redundant check for old_fb != new_fb.
With the proper fix in DRM, this should also fix some cursor stuttering
issues with xf86-video-amdgpu since it double buffers the cursor.
IGT tests that swap framebuffers (-varying-size for example) should
also pass again.

Now that DC has the proper fix complete we can drop the hacks and

[How]
We still need the function pointers hooked up to grab the real uclk
states from pplib. The rest of the prior hack can be reverted.
The key requirements here are really just DC support, updated firmware,
and support for disabling p-state support when needed in pplib/smu.

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.

[Why]
DC configures the GSL group for the pipe when pipe_split is enabled
and we're switching flip types (buffered <-> immediate flip) on DCN2.
In order to record what GSL group the pipe is using DC stores it in
the pipe's stream_res. DM is not aware of this internal grouping, nor
is DC resource.
So when DM creates a dc_state context and passes it to DC the current
GSL group is lost - DM never knew about it in the first place.
After 3 immediate flips we run out of GSL groups and we're no longer
able to correctly perform *any* flip for multi-pipe scenarios.
[How]
The gsl_group needs to be copied to the new context.
DM has no insight into GSL grouping and could even potentially create
a brand new context without referencing current hardware state. So this
makes the most sense to have happen in DC.
There are two places where DC can apply a new context:
- dc_commit_state
- dc_commit_updates_for_stream
But what's shared between both of these is apply_ctx_for_surface.
This logic only matters for DCN2, so it can be placed in
dcn20_apply_ctx_for_surface. Before doing any locking (where the GSL
group is setup) we can copy over the GSL groups before committing the
new context.

variance of latency is small, or that pstate support isn't necessary for correct ASIC functionality.
Newer ASICs violate both existing assumptions. PState support is mandatory of correct ASIC
functionality, but not all latencies have to be supported. Existing code supports a "full p state" which
allows memory clock to change, but is hard for DCN to support (as it requires very large buffers).
New code will now fall back to a "dummy p state" support when "full p state" cannot be support.
This easy p state support should always be allowed.

In dm_helpers_parse_edid_caps, there is a corner case where no speakers

Enabling audio when no speaker allocations exists can cause issues in
the video stream.

1. Stack usage is pretty high as fixed31_32 struct is 8 bytes and we
have functions with >30 vars on the stack.
2. Optimize gamma calculation by reducing number of calls to
dc_fixpt_pow Our X points are divided into 32 regions wth 16 pts each.
Each region is 2x the previous, meaning x[i] = 2*x[i-16] for i>=16.
Using (2x)^gamma = 2^gamma * x^gamma, we can recursively compute powers
of gamma, we just need first 16 pts to start it up. dc_fixpt_pow() is
expensive, it computes x^y by doing exp(y*logx) Exp is done by Taylor
series approximation, and log by Newton-like approximation that also
uses exp internally. In short, it's significantly heavier than
run-of-the-mill addition/subtraction/multiply.

and dp_retrain_link_dp_test() is called, even though it is connected
using a passive dongle.
Add an extra condition in dp_retrain_link_dp_test() to check for
link->dongle_max_pix_clk > 0. This is the only way we know if the
connection is using passive dongle so we don't retrain DP.

[why]
'second_line_offset_adj' was mistakenly left at zero, even though DSC spec
v1.2a recommends setting this field to 512 for 4:2:0.
[how]
Set 'second_line_offset_adj' to 512 for 4:2:0 and leave at zero otherwise

We're not expected to enter the default case, but not returning a
default value here is incorrect.

[Why]
Unintentionally introduced behaviour change from previous refactor,
which causes clks to be 0 in no stream cases, which will cause
divide by 0.
[How]
Skip calculation of clocks when no stream. Which is the same as old
behaviour.
