Track whether pipe gamma is enabled or disabled. For now we
stick to the current behaviour of always enabling gamma. But
we do get working state readout for this now. On SKL+ we use
the pipe bottom color as our hardware state. On pre-SKL we
read the state back from the primary plane control register.
That only really correct for g4x+, as older platforms never
gamma correct pipe bottom color. But doing the readout the
same way on all platforms is fine, and there is no other way
to do it really.

On g4x+ the pipe gamma enable bit for the primary plane affects
the pipe bottom color as well. The same for the pipe csc enable
bit on ilk+. Thus we must configure those bits correctly even
when the primary plane is disabled.
To make the feasible let's split those settings from the
plane_ctl() function into a seprate funciton that we can
call from the ->disable_plane() hook as well.
For consistency we'll do that on all the plane types. While
that has no real benefits at this time, it'll become useful
when we start to control the pipe gamma/csc enable bits
dynamically when we overhaul the color management code.
On pre-g4x there doesn't appear to be any way to gamma
correct the pipe bottom color, but sticking to the same
pattern doesn't hurt. And it'll still help us to do
crtc state readout correctly for the pipe gamma enable
bit for the color management overhaul.
An alternative apporach would be to still precompute these
bits into plane_state->ctl, but that would require that we
run through the plane check even when the plane isn't logically
enabled on any crtc. Currently that condition causes us to
short circuit the entire thing and not call ->check_plane().
There would also be some chicken and egg problems with
->check_plane() vs. crtc color state check that would
requite splitting certain things into multiple steps.
So all in all this seems like the easier route.

The majority of runtime-pm operations are bounded and scoped within a
function; these are easy to verify that the wakeref are handled
correctly. We can employ the compiler to help us, and reduce the number
of wakerefs tracked when debugging, by passing around cookies provided
by the various rpm_get functions to their rpm_put counterpart. This
makes the pairing explicit, and given the required wakeref cookie the
compiler can verify that we pass an initialised value to the rpm_put
(quite handy for double checking error paths).

On icl+ the plane state that gets passed to update_slave() is not
the plane state of the plane we're programming. With NV12 the
plane state would be coming from the master (UV) plane whereas
the plane we're programming is the slave (Y) plane. For that reason
we need to explicitly pass around the slave plane (or we'd have to
otherwise deduce it by checking whether we were called via
.update_plane() or .update_slave()).
In the case of icl_program_input_csc_coeff() it's actually OK to
assume that we are always the master plane because the input CSC
only exists on HDR planes which can never be a slave plane. But
for consistency let's pass in the plane explicitly anyway.
While at it drop the "_coeff" from the function name since it's
kinda redundant, and this makes the name a bit shorter :)

On SKL+ the plane WM/BUF_CFG registers are a proper part of each
plane's register set. That means accessing them will cancel any
pending plane update, and we would need a PLANE_SURF register write
to arm the wm/ddb change as well.
To avoid all the problems with that let's just move the wm/ddb

To make that feasible we'll move the plane ddb tracking into
the crtc state. Watermarks were already tracked there.

We're going to need access to the new crtc state in ->disable_plane()

the crtc state down.
We'll also try to make intel_crtc_disable_planes() do the right
thing as much as it's possible. The fact that we don't have a
separate crtc state for the disabled state when we're going to
re-enable the crtc later means we might end up poking at a few
extra planes in there. But that's harmless. I suppose one might
argue that we wouldn't have to care about proper ddb/wm/csc/gamma
if the pipe is going to permanently disable anyway, but the state

everything is programmed correctly even in that case.

Some observations about the plane registers:
- the control register will self-arm if the plane is not already
enabled, thus we want to write it as close to (or ideally after)
the surface register
- tileoff/linoff/offset/aux_offset are self-arming as well so we want
them close to the surface register as well
- color keying registers we maybe self arming before SKL. Not 100%
sure but we can try to keep them near to the surface register
as well
- chv pipe b csc register are double buffered but self arming so
moving them down a bit
- the rest should be mostly armed by the surface register so we can
safely write them first, and to just for some consistency let's try
to follow keep them in order based on the register offset
None of this will have any effect of course unless the vblank evasion
fails (which it still does sometimes). Another potential future benefit
might be pulling the non-self armings registers outside the vblank
evasion since they won't latch until the arming register has been
written. This would make the critical section a bit lighter and thus
less likely to exceed the deadline.

Reduce the clutter in the sprite update functions by writing

did this for primary planes so might as well do it for the

There is no harm in writing both registers. Which one gets
used depends on the tilimg mode selected in the plane control
registers.
It might even make sense to clear the register that won't
get used. That could make register dumps a little easier to

We configure the chroma upsampler with the same chroma siting as
used by the scaler for consistency, the chroma upsampler is used
instead of the scaler for YUV 4:2:0 on ICL's HDR planes.

The first 3 planes (primary, sprite 0 and 1) have a dedicated chroma
upsampler to upscale YUV420 to YUV444 and the scaler should only be
used for upscaling. Because of this we shouldn't program the scalers
in planar mode if NV12 and the chroma upsampler are used. Instead
program the scalers like on normal planes.
Sprite 2 and 3 have no dedicated scaler, and need to program the
selected Y plane in the scaler mode.
Changes since v1:
- Make the comment less confusing.
Changes since v2:
- Fix checkpatch warning (Matt)
- gen10- -> Pre-gen11 (Ville)
- PS_SCALER_MODE_PACKED -> PS_SCALER_MODE_NORMAL. (Matt)
- Add comment about scaler mode in intel_atomic_setup_scaler(). (Matt)
- Rename need_scaling to need_scaler. (Matt)
- Move the crtc need_scaling check to skl_update_scaler_crtc().

Let's run through the entire plane check even when the plane
is invisible due to zero constant alpha. This makes for more
consistent behaviour since we check the src/dst coordinates,
stride etc. against the hardware limits.

The SKL+ NV12 src width alignment w/a is still living in an odd place.
Everything else was already relocated closer to the main plane check
function. Move this workaround as well.
As a bonus we avoid the funky rotated vs. not mess with the src
coordinates as this now gets checked before we rotate the coordinates.

There's not much point in following the primary vs. sprite split
for the SKL+ universal plane init code. The only difference is
of our own doing in the form of the .check_plane(). Let's make
a small exception for that little detail and otherwise share
the same code to initialize all the universal planes.
Eventually we should eliminate the mess around .check_plane()
as well, but for now let's be happy with some code reduction.
v2: Remember to set up plane->has_fbc
Make skl_plane_has_ccs() static
v3: Rebase due to NV12, rename some variables
v4: Don't leave the color_encoding/range props behind
v5: Rebase dur to blend properties, skl_plane_max_stride() and
skl_plane_check()

No point in having each caller of intel_create_plane_state() initialize
the scaler_id to -1. Instead just do it in intel_create_plane_state().
Previously we left scaler_id at 0 for pre-SKL platforms, but I can't
see how initializing it to -1 always would cause any harm.

We're currently not providing the possible_crtcs mask to
drm_universal_plane_init() for primary/cursor planes. While that does
work on account of drm_crtc_init_with_planes() filling those up
for us, it's inconsisten with what we're doing for sprite planes.
Let's just always pass the possible_crtcs bitmask to
drm_universal_plane_init(). This does assume that crtc->index
== pipe. But we're already making that assumption elsewhere so
it doesn't seem like a very big sin here.
