44505168d7 drm/i915: Drop stealing of bits from i915_sw_fence function pointer
Rather than stealing bits from i915_sw_fence function pointer use
separate fields for function pointer and flags. If using two different
fields, the 4 byte alignment for the i915_sw_fence function pointer can
also be dropped.

v2:
 (CI)
  - Set new function field rather than flags in __i915_sw_fence_init
v3:
 (Tvrtko)
  - Remove BUG_ON(!fence->flags) in reinit as that will now blow up
  - Only define fence->flags if CONFIG_DRM_I915_SW_FENCE_CHECK_DAG is
    defined
v4:
  - Rebase, resend for CI

a59308a5fb drm/i915: Fix fastsets on TypeC ports following a non-blocking modeset
After a non-blocking modeset on a TypeC port's CRTC - possibly blocked
later in drm_atomic_helper_wait_for_dependencies() - a fastset on the
same CRTC may copy the state of CRTC before this gets updated to reflect
the up-to-date DP-alt vs. TBT-alt TypeC mode DPLL used for the CRTC. In
this case after the first (non-blocking) commit completes enabling the
DPLL required for the up-to-date TypeC mode the following fastset will
update the CRTC state pointing to the wrong DPLL. A subsequent disabling
modeset will try to disable the wrong PLL, triggering a state checker
WARN (and leaving the DPLL which is actually used active for good).

Fix the above race by copying the DPLL state for fastset CRTCs from the
old CRTC state at the point where it's guaranteed to be up-to-date
already. This could be handled in the encoder's update_prepare() hook as
well, but that's a bigger change, which is better done as a follow-up.

v2: Copy dpll_hw_state as well. (Ville)

2bbc6fcaf8 drm/i915: Use vblank workers for gamma updates
The pipe gamma registers are single buffered so they should only
be updated during the vblank to avoid screen tearing. In fact they
really should only be updated between start of vblank and frame
start because that is the only time the pipe is guaranteed to be
empty. Already at frame start the pipe begins to fill up with
data for the next frame.

Unfortunately frame start happens ~1 scanline after the start
of vblank which in practice doesn't always leave us enough time to
finish the gamma update in time (gamma LUTs can be several KiB of
data we have to bash into the registers). However we must try our
best and so we'll add a vblank work for each pipe from where we
can do the gamma update. Additionally we could consider pushing
frame start forward to the max of ~4 scanlines after start of
vblank. But not sure that's exactly a validated configuration.
As it stands the ~100 first pixels tend to make it through with
the old gamma values.

Even though the vblank worker is running on a high prority thread
we still have to contend with C-states. If the CPU happens be in
a deep C-state when the vblank interrupt arrives even the irq
handler gets delayed massively (I've observed dozens of scanlines
worth of latency). To avoid that problem we'll use the qos mechanism
to keep the CPU awake while the vblank work is scheduled.

With all this hooked up we can finally enjoy near atomic gamma
updates. It even works across several pipes from the same atomic
commit which previously was a total fail because we did the
gamma updates for each pipe serially after waiting for all
pipes to have latched the double buffered registers.

In the future the DSB should take over this responsibility
which will hopefully avoid some of these issues.

Kudos to Lyude for finishing the actual vblank workers.
Works like the proverbial train toilet.

v2: Add missing intel_atomic_state fwd declaration
v3: Clean up properly when not scheduling the worker
v4: Clean up the rest and add tracepoints
v5: s/intel_wait_for_vblank_works/intel_wait_for_vblank_workers/ (Jani,Uma)

8ac80733cf drm/i915: Split update_plane() into update_noarm() + update_arm()
The amount of plane registers we have to write has been steadily
increasing, putting more pressure on the vblank evasion mechanism
and forcing us to increase its time budget. Let's try to take some
of the pressure off by splitting plane updates into two parts:
1) write all non-self arming plane registers, ie. the registers
   where the write actually does nothing until a separate arming
   register is also written which will cause the hardware to latch
   the new register values at the next start of vblank
2) write all self arming plane registers, ie. registers which always
   just latch at the next start of vblank, and registers which also
   arm other registers to do so

Here we just provide the mechanism, but don't actually implement
the split on any platform yet. so everything stays now in the _arm()
hooks. Subsequently we can move a whole bunch of stuff into the
_noarm() part, especially in more modern platforms where the number
of registers we have to write is also the greatest. On older
platforms this is less beneficial probably, but no real reason
to deviate from a common behaviour.

And let's sprinkle some TODOs around the areas that will need
adapting.

aaec72ee90 drm/i915: Reject planar formats when doing async flips
Async flips are only capable of changing PLANE_SURF, hence we
they can't easily be used with planar formats.

Older platforms could require updating AUX_DIST as well, which
is not possible. We'd have to make sure AUX_DIST doesn't change
before allowing the async flip through. If we could get async
flips with CCS then that might be interesting, but since the hw
doesn't allow async flips with CCS I don't see much point in
allowing this for planar formats either. No one renders their
game content in YUV anyway.

icl+ could in theory do this I suppose since each color plane
has its own PLANE_SURF register, but I don't know if there is
some magic to guarantee that both the Y and UV plane would
async flip synchronously if you will. Ie. beyond just a clean
tear we'd potentially get some kind of weird tear with some
random mix of luma and chroma from the old and new frames.

So let's just say no to async flips when scanning out planar
formats.

96837e8bee drm/i915/adlp/fb: Fix remapping of linear CCS AUX surfaces
During remapping CCS FBs the CCS AUX surface mapped size and offset->x,y
coordinate calculations assumed a tiled layout. This works as long as
the CCS surface height is aligned to 64 lines (ensuring a 4k bytes CCS
surface tile layout).  However this alignment is not required by the HW
(and the driver doesn't enforces it either).

Add the remapping logic required to remap the pages of CCS surfaces
without the above alignment, assuming the natural linear layout of the
CCS surface (vs. tiled main surface layout).

e12d6218fd drm/i915: Reduce bigjoiner special casing

The main things here are that each pipe now does full
clock computation/readout with its own shared_dpll reference.
Also every pipe's cpu_transcoder always points correctly
at the master transcoder.

Due to the above changes state readout is now complete
and all the related hacks can go away. The actual modeset
sequence code is still a mess, but I think in order to clean
that up properly we're probably going to have to redesign
the modeset logic to treat transcoders vs. pipes separately.
That is going to require significant amounts of work.

3991999732 drm/i915: Disable all planes before modesetting any pipes
Let's disable planes on all pipes affected by the modeset before
we start doing the actual modeset. This means we have less
random planes enabled during the modeset, and it also mirrors
what we already do when enabling pipes on skl+ since we enable
planes on all pipes as the very last step. As a bonus we also
nuke a bunch og bigjoiner special casing.

I've occasionally pondered about going even furher here and
doing the pre_plane_update() stuff for all pipes first, then
actually disabling the planes, and finally running the rest
of the modeset sequence. This would potentially allow
parallelizing all the extra vblank waits across multiple pipes,
and would make the plane disable even more atomic. But let's
go one step a time here.

f28c5950d5 Revert "drm/i915/display: Disable audio, DRRS and PSR before planes"
Disabling planes in the middle of the modeset seuqnece does not make
sense since userspace can anyway disable planes before the modeset
even starts. So when the modeset seuqence starts the set of enabled
planes is entirely arbitrary. Trying to sprinkle the plane disabling
into the modeset sequence just means more randomness and potential
for hard to reproduce bugs.

So it makes most sense to just disable all planes first so that the
rest of the modeset sequence remains identical regardless of which
planes happen to be enabled by userspace at the time.

This reverts commit 84030adb9e.

765972cb85 drm/i915/psr: Disable PSR before modesets turn off all planes
PSR2 apparently requires some planes to be enabled for some
silly reason, and so we are now trying to turn PSR off before
planes go off. Except during a full modeset that is handled
less clearly through reorganization of the modeset sequence.
That is not great as it makes the code mode complex, and
prevents us from doing nice things such as just turning off
all the planes at the very start of the modeset. So let's
move the PSR pre_plane_update() thing to a spot where it
will handle both full modesets and everything else.

f9a7b19c48 drm/i915: Move the pxp plane state computation
No real reason to have this pxp state computation in
intel_atomic_check_planes(). Just stuff it into skl_plane_check().

There was also some funny state copying being done from the
old plane state to the new plane state when the plane is anyway
disabled.

The one thing we presumably must remember to do is copy
over the decrypt state when assigning a Y plane for planar
YCbCr scanout, so that the Y plane's PLANE_SURF will get the
appropriate bit set. The force_black thing should not matter
as I'm pretty sure all that stuff is ignored for the Y plane.
I suppose this was the reason for the odd placement for the
state computation, but I see no reason to deviate from the
standard way of doing these things. This also guarantees
that we don't calculate things differently between the
linked UV and Y plane.

v2: Only do stuff for icl+ since 'force_black' depends
    on the plane CSC which is an icl+ feature
