Add a single point of truth for figuring out the primary/secondary crtc
for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple
places.
Also fix the pipe validity checks to properly take non-contiguous pipes
into account. The current checks may theoretically overflow
i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused
off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on
the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.
Prefer primary/secondary terminology going forward.
v2:
- Improved abstractions for pipe validity etc.

This patch adds Pipe A plumbing to the already
existing parsing and loading functions which is
taken care of in the prep patches. Adding MAX_DMC_FW
to keep track for both Main and Pipe A DMC while loading
the respective blobs.
Also adding present field in dmc_info.
s/find_dmc_fw_offset/csr_set_dmc_fw_offset. While at it add
fw_info_matches_stepping() helper. CSR_PROGRAM() should now
take the starting address of the particular blob (Main or Pipe)
and not hardcode it.
v2: Add dmc_offset and start_mmioaddr fields for dmc_info struct.
v3: Add a missing corner cases of stepping-substepping combination in
fw_info_matches_stepping() helper.
v4: Add macro for start_mmioaddr for V1 package. Simplify code

Disconnect TypeC PHYs during system suspend and shutdown, even with the
corresponding TypeC sink still plugged to its connector, since leaving
the PHY connected causes havoc at least during system resume in the
presence of an Nvidia card.
Note that this will only make a difference in the TypeC DP alternate
mode, since in Thunderbolt alternate mode the PHY is never owned by the
display engine and there is no notion of PHY ownership in legacy mode
(the display engine being the only possible owner in that mode and the
TypeC subsystem not having anything to do with the port in that case).

It's becoming pretty cumbersome to track the features enabled going back
to GEN7. Gather the XE_LPD display features together in XE_LPD_FEATURES
macro so they are sufficient to describe the display features.
In ADL-P's device_info we set has_psr_hw_tracking to 0 as it would
otherwise be enabled since it is inheriting from GEN12_FEATURES.

Currently as the workaround is applied the screen flickers. As a result
we do not achieve seamless boot experience.
Avoiding the issue in the common use-case might be hard, although we can
resolve it for dual GPU setups - when the "other" GPU is primary and/or
outputs are connected to it.
With this I was able to get seamless experience on my Intel/Nvidia box,
running systemd-boot and sddm/Xorg. Note that the i915 driver is within
initrd while the Nvidia one is not.
Without this patch, the splash presented by systemd-boot (UEFI BGRT) is
torn down as the code-path kicks in, leaving the monitor blank until the
login manager starts.
Same issue were reported with plymouth/grub, although personally I
wasn't able to get them to behave on my setup.

We currently treat same slice mask as a same DBuf state and skip
updating the Dbuf slices, if we detect that.
This is wrong as if we have a multi to single pipe change or
vice versa, that would be treated as a same Dbuf state and thus
no changes required, so we don't get Mbus updated, causing issues.
Solution: check also mbus_join, in addition to slices mask.

This introduces the following function that can exit and activate a psr
source when intel_psr is already enabled.
- intel_psr_pause(): Pause current PSR. It deactivates current psr state.
- intel_psr_resume(): Resume paused PSR. It activates paused psr state.
v2: Address Jose's review comment.
- Remove unneeded changes around the intel_psr_enable().
- Add intel_psr_post_exit() which processes waiting until PSR is idle
and WA for SelectiveFetch.
v3: Address Jose's review comment.
- Rename intel_psr_post_exit() to intel_psr_wait_exit_locked().
- Move WA_1408330847 to intel_psr_disable_locked()
- If the PSR is paused by an explicit intel_psr_paused() call, make the
intel_psr_flush() not to activate PSR.
v4: Address Jose's review comment.
- In order to avoid the scenario of PSR is not active but there is a
scheduled psr->work, it changes the check routine of intel_psr_pause()
for PSR's enablement from "psr->active" to "psr->enable".

When PSR is enabled it handles DP_SDP_VSC, changing revision and all
the other fields as necessary.
It can also enabled and disable this SDP as needed without a full
modeset.
So here masking DP_SDP_VSC bit when previous and future state PSR
enabled, it will still be checked when comparing the asked state
to what was programmed to hardware.

Commit 78b772e1a01f ("drm/i915/display: Fill PSR state during hardware
configuration read out") is not allowing fastsets to happen when PSR
states changes but PSR is a feature that can be enabled and disabled
during fastsets.
So here moving the PSR pipe conf checks to a block that is only
executed when checking if HW state matches with requested state, not
during the phase where it checks if fastset is possible or not.
There still a state mismatch not allowing fastsets between states
turning off or on PSR because of crtc_state->infoframes.enable
BIT(DP_SDP_VSC) but at least for now it will allow a fastset between
PSR1 <-> PSR2, that is a case heavilly used by CI due to pipe CRC not
work with PSR2, but the remaning issue will be fixed in a future patch.

An async-put on an encoder specific power domain (for instance the AUX
PW domain) may be pending when removing the encoder. Make sure any such
async-puts are complete while the corresponding encoder is still in place
since at least AUX power wells require this to do a power well->PHY
lookup.

The FIFO underrun recovery mechanism has a boatload of cases
where it can't be used. The description is also a bit ambiguous
as it doesn't specify whether plane downscaling needs to be considered
or just pipe downscaling. We may not even have sufficient state
tracking to decide this on demand, so for now just disable the
whole thing.

The kernel prefers enabling fbc over the initial fb, since this leads to
actual runtime power savings, so if the initial fb is deemed too big
using some heuristic, then we simply skip allocating stolen for it.
However if the kernel is not configured with fbcon then it should be
possible to relax this, since unlike with fbcon the display server
shouldn't preserve it when later replacing it, and so we should be able
to re-use the stolen memory for fbc and friends. This patch is reported
to fix some flicker seen during boot splash on some devices.

On XE_LPD, VRR CTL register adds a new VRR Guardband bitfield
replacing the pipeline full and deprecating the pipeline override
bit.
This patch adds this corresponding bitfield in the register defs,
crtc state vrr structure and populates this in vrr compute
config and vrr enable functions. It also adds the corresponding
HW state readout for this field.

XE_LPD brings enhanced underrun recovery: the hardware can somewhat
mitigate underruns by using an interpolated replacement pixel (soft
underrun) or the previous pixel (hard underrun). Furthermore, underruns
can now be caused downstream by the port, even if the pipe itself is
operating properly. The interrupt register and PIPE_STATUS register
give us extra bits to recognize hard/soft underruns and determine
whether the underrun was caused by the port, so we'll use that
information to print some more descriptive errors when underruns occur.
v2:
- Keep ICL's PIPE_STATUS defined separately from the old GMCH pipe
status register. (Ville)
- Only read/clear the PIPE_STATUS register on platforms with
display ver >= 11. (Lucas)
v3:
- Actually enable+unmask all the new underrun interrupts, clear stale
bits out from PIPE_STATUS before enabling the interrupts, report all
FIFO underruns errors at once, rename a bunch of stuff to unconfuse
vs. PIPESTAT. (Ville)
