UAPI Changes:
- Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709"
The intent of Wa_14015141709 was to inform us that userspace can no
longer control object-level preemption as it has on past platforms
(i.e., by twiddling register bit CS_CHICKEN1[0]). The description of
the workaround in the spec wasn't terribly well-written, and when we
requested clarification from the hardware teams we were told that on the
kernel side we should also probably stop setting
FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the
hardware to honor the settings in per-context register CS_CHICKEN1. It
turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a
mistake; even though CS_CHICKEN1[0] is non-operational and useless to
userspace, there are other bits in the register that do still work and
might need to be adjusted by userspace in the future (e.g., to implement
other workarounds that show up). If we don't set
FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would
not take effect.

On BDW+ M/N are double buffered and so we can easily reprogram them
during a fastset. So for eDP panels that support seamless DRRS we
can just change these without a full modeset.
For earlier platforms we'd need to play tricks with M1/N1 vs.
M2/N2 during the fastset to make sure we do the switch atomically.
Not sure the added complexity is worth the hassle, so leave it
alone for now.
The slight downside is that we have to keep the link running at
a link rate capable of supporting the highest refresh rate we
want to use. For the moment we just pick the highest mode the
panel reports and calculate the link based on that. This might
need further refinement (eg. if we run into bandwidth
restrictions)...
v2: Only use the high link rate if the platform really supports
the seamless M/N change uring fastset (ie. bdw+)

Now that we no longer fuzz M/N during fastset these should
match exctly.
In order to get a match with what the BIOS does we need to round
M/N down. And we do the opposite rounding when doing the readback.
That gets us pretty much the same thing back.
There can still be slight rounding differences between FDI M/N
vs. the DPLL output so we allow for tiny deviation in
intel_pipe_config_sanity_check().

Do the DPLL computation before fastset checks. This should
allow us to get rid of all that horrible fuzzy clock handling
for fastsets. Who knows how many bugs there are caused by our
state not actually matching what the hardware will generate.

Only reassign the pipe's DPLL if it's going through a full
.compute_config() cycle. If OTOH it's just getting modeset
eg. in order to change cdclk there doesn't seem much point in
picking a new DPLL for it.
This should also prevent .get_dplls() from seeing a funky port_clock
for DP even in cases where the readout produces a non-standard
clock and we (for some reason) have decided to not fully recompute
the state to remedy the situation.

Currently we calculate a lot of things (pixel rate, watermarks,
cdclk) trusting that the DPLL can generate the exact frequency
we ask it. In practice that is not true and there can be
certain amount of rounding involved.
To allow us to eventually get accurate numbers for all our
DPLL clock derived state we need to move the DPLL calculation
to hapen much earlier. To that end we hoist it up to the just
after the fastset checks. For now we just do the easy code
motion, and the actual back feeding of the final DPLL clock
into the state will come later.
A slight change here is that now .crtc_compute_clock()
can get called while the shared_dpll is still assigned.
But since .crtc_compute_clock() no longer assignes new
shared_dplls this is perfectly fine.
TODO: I'd actually like to do this before the fastset check
so that if the DPLL state should change we actually do the
modeset. Which I think is what the video aficionados want,
but it might not be what the fans of fastboot want. Not yet
sure how to reconcile those conflicting requirements...

unregistered the acpi_video0 device to avoid there being 2 backlight
devices (when acpi_video_get_backlight_type()==native).
This means that userspace used to briefly see 2 devices and the
disappearing of acpi_video0 after a brief time confuses the systemd
backlight level save/restore code, see e.g.:
https://bbs.archlinux.org/viewtopic.php?id=269920
To fix this the ACPI video code has been modified to make backlight class
device registration a separate step, relying on the drm/kms driver to
ask for the acpi_video backlight registration after it is done setting up
its native backlight device.
Add a call to the new acpi_video_register_backlight() after the i915 calls
acpi_video_register() (after setting up the i915 opregion) so that the
acpi_video backlight devices get registered on systems where the i915
native backlight device is not registered.
Changes in v2:
-Only call acpi_video_register_backlight() when a panel is detected
Changes in v3:
-Add a new intel_acpi_video_register() helper which checks if a panel
is present and then calls acpi_video_register_backlight()

As Daniel Vetter pointed out, if we only use the atomic modesetting locks
with MST it's technically possible for a driver with non-blocking modesets
to race when it comes to MST displays - as we make the mistake of not doing
our own CRTC commit tracking in the topology_state object.
This could potentially cause problems if something like this happens:
* User starts non-blocking commit to disable CRTC-1 on MST topology 1
* User starts non-blocking commit to enable CRTC-2 on MST topology 1
There's no guarantee here that the commit for disabling CRTC-2 will only
occur after CRTC-1 has finished, since neither commit shares a CRTC - only
the private modesetting object for MST. Keep in mind this likely isn't a
problem for blocking modesets, only non-blocking.
So, begin fixing this by keeping track of which CRTCs on a topology have
changed by keeping track of which CRTCs we release or allocate timeslots
on. As well, add some helpers for:
* Setting up the drm_crtc_commit structs in the ->commit_setup hook
* Waiting for any CRTC dependencies from the previous topology state
v2:
* Use drm_dp_mst_atomic_setup_commit() directly - Jani

Move the panel specific VBT parsing to happen during the
output probing stage. Needs to be done because the VBT
parsing will need to look at the EDID to determine
the correct panel_type on some machines.
We split the parsed VBT data (i915->vbt) along the same
boundary. For the moment we just hoist all the panel
specific stuff into connector->panel.vbt since that seems
like the most convenient place for eg. the backlight code.
Note that we simply drop the drrs type check from
intel_drrs_frontbuffer_update() since that operates on the whole
device rather than a specific connector/encoder. But the check
was just a micro optimization so removing it doesn't actually
mattter for correctness.

Let's make sure FBC is always disabled when we start to take

I suspect this should never really happen, since the only time
when we really should be taking over with the display already
active is when the previous state was progammed by the BIOS,
which likely shouldn't use FBC. This could be driver init,

PIPE_MBUS_DBOX_CTL was only being programmed when a pipe is being
enabled but that could potentially cause issues as it could have
mismatching values while pipes are being enabled.
So here moving the PIPE_MBUS_DBOX_CTL programming of all pipes to be
executed before the function that enables all pipes, leaving all pipes
with a matching A_CREDIT value.
While at it, also moving it to intel_pm.c as we are trying to reduce

programing sequences.
v2:
- do not program PIPE_MBUS_DBOX_CTL if pipe will not be active or
when it do not needs modeset
- remove the checks to wait a vblank
v3:
- checking if dbuf state is present in state before using it
v4:

Handle the plane relative data rate in exactly the same
way as we already handle the real data rate. Ie. pre-calculate

it for the Y plane as needed. This should guarantee that the
tracking is 100% consistent, and makes me have to think less
when the same apporach is used by both types of data rate.
We might even want to consider replacing the relative

struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.
Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.
Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

Now that we track framestart_delay in the crtc state with readout
and state checker support we can remove the explicit framestart_delay
sanitation code.
Also I'm not convinced reprogramming this while the pipe is running
is even valid. CHICKEN_TRANS (hsw+) and TRANS_CHICKEN2 (cpt+) docs
at least make no mention of double buffering which seems to imply
that live reprogramming is not supported. On older platforms
PIPECONF and PCH_TRANSCONF (ibx) are double buffered though, so
might be that we could do this on the older platforms. But doesn't
really make sense to special case old platforms for this.
So from now on if the BIOS has misprogrammed this we shall simply do
a full modeset at boot to fix it up. Such systems will of course lose
fastboot, but I think less code (and less uncertainty what
reprogramming this on a running pipe will even do) outweighs that.

The current implementation of the async flip wm0/ddb optimization
does not work at all. The biggest problem is that we skip the
whole intel_pipe_update_{start,end}() dance and thus never actually
complete the commit that is trying to do the wm/ddb change.
To fix this we need to move the do_async_flip flag to the crtc
state since we handle commits per-pipe, not per-plane.
Also since all planes can now be included in the first/last
"async flip" (which gets converted to a sync flip to do the
wm/ddb mangling) we need to be more careful when checking if
the plane state is async flip comptatible. Only planes doing
the async flip should be checked and other planes are perfectly
fine not adhereing to any async flip related limitations.
However for subsequent commits which are actually going do the
async flip in hardware we want to make sure no other planes
are in the state. That should never happen assuming we did our
job correctly, so we'll toss in a WARN to make sure we catch
any bugs here.

"can the requested plane do async flips at all?" check
much earlier. For this purpose we introduce
intel_async_flip_check_uapi() that gets called early during
the atomic check.
And for good measure we'll throw in a couple of basic checks:
- is the crtc active?
- was a modeset flagged?
- is+was the plane enabled?
Though atm all of those should be guaranteed by the fact
that the async flip can only be requested through the legacy
page flip ioctl.

When calculating pipe_mode and when doing readout we need
to order our steps correctly.
1. We start with adjusted_mode crtc timings being populated
with the transcoder timings (either via readout or
compute_config(). These will be per-segment for MSO.
2. For all other uses we want the full crtc timings so
we ask intel_splitter_adjust_timings() to expand
the per-segment numbers to their full glory
3. If bigjoiner is used we the divide the full numbers
down to per-pipe numbers using intel_bigjoiner_adjust_timings()
During readout we also have to reconstruct the adjusted_mode
normal timings (ie. not the crtc_ stuff). These are supposed
to reflect the full timings of the display. So we grab these
between steps 2 and 3.
The "user" mode readout (mainly done for fastboot purposes)
should be whatever mode the user would have used had they
asked us to do a modeset. We want the full timings for this
as the per-segment timings are not suppoesed to be user visible.
Also the user mode normal timings hdisplay/vdisplay need to
match PIPESRC (that is where we get our PIPESRC size
we doing a modeset with a user supplied mode).
And we end up with
- adjusted_mode normal timigns == full timings
- adjusted_mode crtc timings == transcoder timings
(per-segment timings for MSO, full timings otherwise)
- pipe_mode normal/crtc timings == pipe timings
(full timings divided by the number of bigjoiner pipes, if any)
- user mode normal timings == full timings with
hdisplay/vdisplay replaced with PIPESRC size
- user mode crtc timings == full timings
Yes, that is a lot of timings. One day we'll try to remove
some of the ones we don't actually need to keep around...

Currently we just leave the old gunk lying around in the crtc
state when userspace asks us to fully disable the crtc. That
doesn't match what the state would be had we never even enabled
the crtc in the first place. So let's make this consistent and
call intel_crtc_prepare_cleared_state() for disabled crtcs as well
(excluding bigjoiner slaves of course which have had their state
copied from the master).
I actually already did this once in commit fff13e63a1 ("drm/i915:
Clear most of crtc state when disabling the crtc") but then
commit 19f65a3dbf ("drm/i915: Try to make bigjoiner work in atomic

DG2 supports a 5th display output which the hardware refers to as "TC1,"
even though it isn't a Type-C output. This behaves similarly to the TC1
on past platforms with just a couple minor differences:
* DG2's TC1 bit in SDEISR is at bit 25 rather than 24 as it is on
ICP/TGP/ADP.
* DG2 doesn't need the hpd inversion setting that we had to use on DG1

Get rid of the inflexible bigjoiner_linked_crtc pointer thing
and just track things as a bitmask of pipes instead. We can
also nuke the bigjoiner_slave boolean as the role of the pipe
can be determined from its position in the bitmask.
It might be possible to nuke the bigjoiner boolean as well
if we make encoder.compute_config() do the bitmask assignment
directly for the master pipe. But for now I left that alone so
that encoer.compute_config() will just flag the state as needing
bigjoiner, and the intel_atomic_check_bigjoiner() is still
responsible for determining the bitmask. But that may have to change
as the encoder may be in the best position to determine how
exactly we should populate the bitmask.
Most places that just looked at the single bigjoiner_linked_crtc
now iterate over the whole bitmask, eliminating the singular
slave pipe assumption.

Currently the bigjoiner state copy logic is kind of
a byzantine mess.
Clean it up to operate in the following manner during a full
modeset:
1) master uapi -> hw state copy
2) master hw -> slave hw state copy
And during a non-modeset update we do:
1) master uapi -> hw state light copy
2) master hw -> slave hw state light copy
I think that is now easier to reason about since we never do
any kind of master uapi -> slave hw state copy short circuit
that could happen previously.
Obviously this does now depend on the master uapi->hw copy
always happening before the master hw -> slave hw copy, but
that is guaranteed by the fact that we always add both crtcs
to the state early, the crtcs are registered in pipe
order (so the compute_config loop happens in pipe order),
and the hardware requires the master pipe has to be lower
than the slave pipe as well. And for good measure we shall
add a check+WARN for this before doing the bigjoiner crtc
assignment.

There's some weird junk in intel_atomic_check_bigjoiner()
that's trying to look at the old crtc state's bigjoiner
usage for some reason. That code is totally unnecessary,
and maybe even actively harmful. Not entirely sure which
since it's such a mess that I can't actually wrap my brain
around what it ends up doing.
Either way, thanks to intel_bigjoiner_add_affected_crtcs()
all of the old bigjoiner crtcs are guaranteed to be in the
state already if any one of them is in the state. Also if
any one of those crtcs got flagged for a modeset, then all
of them will have been flagged, and the bigjoiner links
will have been detached via kill_bigjoiner_slave().
So there is no need to look examing any old bigjoiner
usage in intel_atomic_check_bigjoiner(). All we have to care
about is whether bigjoiner is needed for the new state,
and whether we can get the slave crtc we need.

to copy over the color_mgmt_changed flag so potentially we fail

On TGL/RKL the BIOS likes to use some kind of bogus DBUF layout
that doesn't match what the spec recommends. With a single active
pipe that is not going to be a problem, but with multiple pipes
active skl_commit_modeset_enables() goes into an infinite loop
since it can't figure out any order in which it can commit the
pipes without causing DBUF overlaps between the planes.
We'd need some kind of extra DBUF defrag stage in between to
make the transition possible. But that is clearly way too complex
a solution, so in the name of simplicity let's just sanitize the
DBUF state by simply turning off all planes when we detect a
pipe encroaching on its neighbours' DBUF slices. We only have
to disable the primary planes as all other planes should have
already been disabled (if they somehow were enabled) by
earlier sanitization steps.
And for good measure let's also sanitize in case the DBUF
allocations of the pipes already seem to overlap each other.

We can also get rid of the gen2 vs. gen3+ nonsense since none
of the extra bits ever did anything and just always read
as zero. And now we extend all platforms to use the tgl+

There's no need to store all this stuff in intel_fbc_state_cache.
Just check it all against the plane/crtc states and store only
what we need. Probably more should get nuked still, but this
is a start.
So what we'll do is:
- each plane will check its own state and update its local
no_fbc_reason
- the per-plane no_fbc_reason (if any) then gets propagated
to the cache->no_fbc_reason while doing the actual update
- fbc->no_fbc_reason gets updated in the end with either
the value from the cache or directly from frontbuffer
tracking
It's still a bit messy, but should hopefuly get cleaned up
more in the future. At least now we can observe each plane's
reasons for rejecting FBC now more consistently, and we don't
have so mcuh redundant state store all over the place.

With both integrated and discrete Intel GPUs in a system, the current
global check of intel_iommu_gfx_mapped, as done from intel_vtd_active()
may not be completely accurate.
In this patch we add i915 parameter to intel_vtd_active() in order to
prepare it for multiple GPUs and we also change the check away from Intel
specific intel_iommu_gfx_mapped (global exported by the Intel IOMMU
driver) to probing the presence of IOMMU on a specific device using
device_iommu_mapped().
This will return true both for IOMMU pass-through and address translation
modes which matches the current behaviour. If in the future we wanted to
distinguish between these two modes we could either use
iommu_get_domain_for_dev() and check for __IOMMU_DOMAIN_PAGING bit
indicating address translation, or ask for a new API to be exported from
the IOMMU core code.

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.

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.

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.

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.

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).

Try to make bigjoiner pipes less special.
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.

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.

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.

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.

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.

Add support to enable/disable PLANE_SURF Decryption Request bit.
It requires only to enable plane decryption support when following
condition met.
1. PXP session is enabled.
2. Buffer object is protected.
v2:
- Used gen fb obj user_flags instead gem_object_metadata. [Krishna]
v3:
- intel_pxp_gem_object_status() API changes.
v4: use intel_pxp_is_active (Daniele)
v5: rebase and use the new protected object status checker (Daniele)
v6: used plane state for plane_decryption to handle async flip
as suggested by Ville.
v7: check pxp session while plane decrypt state computation. [Ville]
removed pointless code. [Ville]
v8 (Daniele): update PXP check
v9: move decrypt check after icl_check_nv12_planes() when overlays
have fb set (Juston)
v10 (Daniele): update PXP check again to match rework in earlier
patches and don't consider protection valid if the object has not
been used in an execbuf beforehand.

While sanitizing the hardware state we're currently forcing
the pipe bottom color legacy csc/gamma bits on. That is not a
good idea as BIOSen are likely to leave gabage in the LUTs and
so doing this causes ugly visual glitches if and when the
planes covering the background get disabled. This was exactly
the case on this Dell Precision 5560 tgl laptop.
On icl+ we don't normally even use these legacy bits
anymore and instead use their GAMMA_MODE counterparts.
On earlier platforms the bits are used, but we still
shouldn't force them on without knowing what's in the LUT.
So two options, get rid of the whole thing, or do what
intel_color_commit() does to make sure the bottom color state
matches whatever out hardware readout produced. I chose the
latter since it'll match what happens on older platforms when
the primary plane gets turned off. In fact let's just call
intel_color_commit(). It'll also do some CSC programming but
since we don't have readout for that it'll actually just set
to all zeros. So in the unlikely case of CSC actually being
enabld by the BIOS we'll end up with all black until the first
atomic commit happens.
Still not totally sure what we should do about color management
features here in general. Probably the safest thing would be to
force everything off exactly at the same time when we disable
the primary plane as there is no guarantees that whatever the
LUTs/CSCs contain make any sense whatsoever without the
specific pixel data in the BIOS fb. And if we preserve the
primary plane then we should disable the color management
features exactly when the primary plane fb contents first
changes since the new content assumes more or less no
transformations. But of course synchronizing front buffer
rendering with anything else is a bit hard...

Move assert_panel_unlocked() to intel_pps.c and rename
assert_pps_unlocked(). Keep the functionality and the assert code
together.
There's still a bit of a split between the eDP PPS usage in intel_pps.c
and all the other PPS usage, and assert_pps_unlocked() is arguably more
related to the latter. However, intel_pps.c is the best fit for anything
touching the PPS registers.

This unnecessary flushes are hurting power-savings are it causes
features like PSR, FBC and DRRS to disable it self to handle
frontbuffer rendering, below some explanation of why each removed
call is not necessary.
The flush in intel_prepare_plane_fb() is not required as framebuffer
will be flipped and power-saving features do the proper flip handling
in hardware.
intel_find_initial_plane_obj() flush is not required because it is
only executed during driver load and at this point the power-saving
features are not even enabled.
And the last one intelfb_create(), is also not required as at this
point the fbdev was just allocated, userspace will draw on
it what will trigger frontbuffer invalidates and flushes later on.

Adjust the HSW+ transcoder state readout to just read through
all the possible transcoders for the pipe, and stuff the results
in a bitmask.
We can conveniently cross check the bitmask for invalid
combinations of enabled transcoders, and later we can easily
extend the bitmask readout to handle the bigjoiner case.
One slight change in behaviour is that we no longer read out
the AONOFF->force_pfit.pfit bit for all the enabled "panel
transcoders". But having more than one enabled would anyway
be illegal so no big loss. Also the AONOFF selection should
only ever be used on HSW, which only has the EDP transcoder
an no DSI transcoders.

PSR always had a requirement to only be enabled if there is active
planes but not following that never caused any issues.
But that changes in Alderlake-P, leaving PSR enabled without
active planes causes transcoder/port underruns.
Similar behavior was fixed during the pipe disable sequence by
commit 84030adb9e ("drm/i915/display: Disable audio, DRRS and PSR before planes").
intel_dp_compute_psr_vsc_sdp() had to move from
intel_psr_enable_locked() to intel_psr_compute_config() because we
need to be able to disable/enable PSR from atomic states without
connector and encoder state.

Add support for remapping CCS FBs on ADL-P to remove the restriction
of the power-of-two sized stride and the 2MB surface offset alignment
for these FBs.
We can only remap the tiles on the main surface, not the tiles on the
CCS surface, so userspace has to generate the CCS surface aligning to
the POT size padded main surface stride (by programming the AUX
pagetable accordingly). For the required AUX pagetable setup, this
requires that either the main surface stride is 8 tiles or that the
stride is 16 tiles aligned (= 64 kbytes, the area mapped by one AUX
PTE).
v2:
- Init intel_remapped_info::plane_alignment only for remapped views and
do this from intel_fb_view_init().

PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder.
Bigjoiner is making life even more confusing by introducing
a N:1 relationship between pipes and transcoders. In that case
we only enable/configure the transcoder corresponding to the
master pipe. Let's do some renames to make it clear we're dealing
with the transcoder rather than pipe when it comes to
PIPECONF/TRANSCONF.
I decided to leave the _cpu_ part out from the function/macro
names since the PCH transcoder related stuff already has a
_pch_ in their name. So shouldn't be possible to confuse them.

On Intel platforms we know that the ACPI connector device
node order will follow the order the driver (i915) decides.
The decision is made using the custom Intel ACPI OpRegion
(intel_opregion.c), though the driver does not actually know
that the values it sends to ACPI there are used for
associating a device node for the connectors, and assigning
address for them.
In reality that custom Intel ACPI OpRegion actually violates
ACPI specification (we supply dynamic information to objects
that are defined static, for example _ADR), however, it
makes assigning correct connector node for a connector entry
straightforward (it's one-on-one mapping).
Changes in v2 (Hans de goede):
- Take a reference on the fwnode which we assign to the connector,
for ACPI nodes this is a no-op but in the future we may see
software-fwnodes assigned to connectors which are ref-counted.

- lots of implicit fencing rules documented and fixed up in drivers
- msm now uses the core scheduler
- the irq midlayer has been removed for non-legacy drivers
- the sysfb code now works on more than x86.

Apparently the last reader of i915->active_pipes was removed with commit
ef79d62b5c ("drm/i915: Encapsulate dbuf state handling harder"), and
now it's only ever written to. Remove it completely.

The current gen2 DPLL readout code:
* assumes i845/i865 have LVDS which is not true
* assumes only pipe B can drive LVDS (true, but makes
the code appear a bit magical)
* hard to parse in general
Clean it up by checking for i85x (the only gen2 platform
with LVDS) and reusing intel_lvds_port_enabled().
