[Why]
If system is overclocked, only 1 bounding box state will
be sent by SMU. This results in an empty state being copied
for DML calculations causing black screens and corruption.
[How]
Fully populate bounding box before duplicating last state.

[Why]
Color corruption can occur on bootup into a login
manager that applies a non-linear gamma LUT because
the LUT may not actually be powered on before writing.
It's cleared on the next full pipe reprogramming as
we switch to LUTB from LUTA and the pipe accessing
the LUT has taken it out of light sleep mode.
[How]
The MPCC_OGAM_MEM_PWR_FORCE register does not force
the current power mode when set to 0. It only forces
when set light sleep, deep sleep or shutdown.
The register to actually force power on and ignore
sleep modes is MPCC_OGAM_MEM_PWR_DIS - a value of 0
will enable power requests and a value of 1 will
disable them.
When PWR_FORCE!=0 is combined with PWR_DIS=0 then
MPCC OGAM memory is forced into the state specified
by the force bits.
If PWR_FORCE is 0 then it respects the mode specified
by MPCC_OGAM_MEM_LOW_PWR_MODE if the RAM LUT is not
in use.
We set that bit to shutdown on low power, but otherwise
it inherits from bootup defaults.
So for the fix:
1. Update the sequence to "force" power on when needed
We can use MPCC_OGAM_MEM_PWR_DIS for this to turn on the
memory even when the block is in bypass and pending to be
enabled for the next frame.
We need this for both low power enabled or disabled.
If we don't set this then we can run into issues when we
first program the LUT from bootup.
2. Don't apply FORCE_SEL
Once we enable power requests with DIS=0 we run into the
issue of the RAM being forced into light sleep and being
unusable for display output. Leave this 0 like we used to
for DCN20.
3. Rely on MPCC OGAM init to determine light sleep/deep sleep
MPC low power debug mode isn't enabled on any ASIC currently
but we'll respect the setting determined during init if it
is.
Lightly tested as working with IGT tests and desktop color
adjustment.
4. Change the MPC resource default for DCN30
It was interleaving the dcn20 and dcn30 versions before
depending on the sequence.
5. REG_WAIT for it to be on whenever we're powering up the
memory
Otherwise we can write register values too early and we'll
get corruption.

member in struct NISLANDS_SMC_SWSTATE
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Use flexible-array member in struct NISLANDS_SMC_SWSTATE, instead of

Also, this helps with the ongoing efforts to enable -Warray-bounds by

dcn21_validate_bandwidth() calls functions that use floating point math.
On my machine this sometimes results in simd exceptions when there are
other FPU users such as KVM virtual machines running. The screen freezes
completely in this case.
Wrapping the function with DC_FP_START()/DC_FP_END() seems to solve the
problem. This mirrors the approach used for dcn20_validate_bandwidth.

SISLANDS_SMC_SWSTATE

We tend to use output_format!=RGB as a shorthand for YCbCr, but
this fails if we have a disabled crtc where output_format==INVALID.
We're now getting some fail from intel_color_check() when we have:
hw.enable==false
hw.ctm!=NULL
output_format==INVALID
Let's avoid that by throwing INTEL_OUTPUT_FORMAT_INVALID to the
dumpster, and thus everything defaults to RGB when the crtc
is disabled.
This does beg the deeper question of how much of the state
should we in fact be validating when hw/uapi.enable==false.
And should we even be doing the uapi->hw copy when
uapi.enable==false? So far I've not been able to come up with
satisfactory answers for myself, so I'm putting it off for the
moment.

It's possible to modeset a connector/mst port that has a 0 full_pbn
value: if the sink on the port deasserts its HPD and a branch device
reports this via a CSN with the port's ddps=0 and pdt!=NONE the driver
clears full_pbn, but the corresponding connector can be still
modesetted.
This happened on a DELL U2719D monitor as the branch device and an LG
27UL650-W daisy-chained to it, the LG monitor generating a long HPD
pulse (doing this for some reason always when waking up from some power
saving state).
Tune down the WARN about this scenario to a debug message.

-Wunintialized was disabled in commit c5627461490e ("drm/i915: Disable
-Wuninitialized") because there were two warnings that were false
positives. The first was due to DECLARE_WAIT_QUEUE_HEAD_ONSTACK, which
was fixed in LLVM 9.0.0. The second was in busywait_stop, which was
fixed in LLVM 10.0.0 (issue 415). The kernel's minimum version for LLVM
is 10.0.1 so this warning can be safely enabled, where it has already
caught a couple bugs.

As HW cursor BOs never move, we can store the offset in VRAM in the

The BOs of the hardware cursor are now mapped permanently while the
cursor plane is being used. This reduces the CPU overhead of the cursor
plane's atomic_update function.
The change also resolves a problem with the vmap call in the commit tail.
The vmap implementation could acquire the DMA reservation lock on the
BO, which is not allowed that late in the atomic update. Removing the
vmap call from atomic_update fixes the issue.

ilk+ planes get notably unhappy when the plane x+w exceeds
the stride. This wasn't a problem previously because we
always aligned SURF to the closest tile boundary so the
x offset never got particularly large. But now with async
flips we have to align to 256KiB instead and thus this
becomes a real issue.
On ilk/snb/ivb it looks like the accesses just wrap
early to the next tile row when scanout goes past the
SURF+n*stride boundary, hsw/bdw suffer more heavily and
start to underrun constantly. i965/g4x appear to be immune.
vlv/chv I've not yet checked.
Let's borrow another trick from the skl+ code and search
backwards for a better SURF offset in the hopes of getting the
x offset below the limit. IIRC when I ran into a similar issue
on skl years ago it was causing the hardware to fall over
pretty hard as well.
And let's be consistent and include i965/g4x in the check
as well, just in case I just got super lucky somehow when
I wasn't able to reproduce the issue. Not that it really
matters since we still use 4k SURF alignment for i965/g4x
anyway.
