c40a253b71 drm/i915: Introduce encoder->get_buf_trans()
Convert the get_buf_trans() functions into an encoder vfunc.
Allows us to get rid of bunch of platform if-ladders.

d2c496f7c9 drm/i915: Store the HDMI default entry in the bug trans struct
Store the default HDMI buf trans entry in struct intel_ddi_buf_trans
so that it's next to the actual table. This let's us start ridding
ourselves of some platofrm specifics in intel_ddi_hdmi_num_entries().

17203224f0 drm/i915/dsc: abstract helpers to get bigjoiner primary/secondary crtc
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.

151ec347b0 drm/i915: Force a TypeC PHY disconnect during suspend/shutdown
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).

b91e3c830f drm/i915/xelpd: break feature inheritance
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.

a3af014066 drm/i915: apply WaEnableVGAAccessThroughIOPort as needed
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.

0d6695b112 drm/i915/adl_p: Same slices mask is not same Dbuf state
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.

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().

    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".

9b2e49a148 drm/i915/display: Fix fastsets involving PSR
Commit 78b772e1a0 ("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.

40e40e63f7 drm/i915/display: relax 2big checking around initial fb
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.
