Recompute the state of all CRTCs on an FDI link during a modeset that
may be affected by the modeset of other CRTCs on the same link. This
ensures that each CRTC on the link maximizes its BW use (after another
CRTC is disabled).
In practice this means recomputing pipe B's config on IVB if pipe C gets
disabled.
v2:
- Add the change recomputing affected CRTC states in a separate patch.
(Ville)
v3: (Ville)
- Constify old and new crtc states.
- Check for fused off pipe C.
- Fix new vs. old crtc state mixup.
- Drop check for pipe C's enabled state.

At the moment modesetting pipe C on IVB will fail if pipe B uses 4 FDI
lanes. Make the BW sharing more dynamic by trying to reduce pipe B's
link bpp in this case, until pipe B uses only up to 2 FDI lanes.
For this instead of the encoder compute config retry loop - which
reduced link bpp only for the encoder's pipe - reduce the maximum link
bpp for pipe B/C as required after all CRTC states are computed and
recompute the CRTC states with the new bpp limit.
Atm, all FDI encoder's compute config function returns an error if a BW
constrain prevents increasing the pipe bpp value. The corresponding
crtc_state->bw_constrained check can be replaced with checking
crtc_state->max_link_bpp_x16, add TODO comments for this. SDVO is an
exception where this case is only handled in the outer config retry
loop, failing the modeset with a WARN, add a FIXME comment to handle
this in the encoder code similarly to other encoders.
v2:
- Don't assume that a CRTC is already in the atomic state, while
reducing its link bpp.
- Add DocBook description to intel_fdi_atomic_check_link().
v3:
- Enable BW management for FDI links in a separate patch. (Ville)

At the moment a modeset fails if the config computation of a pipe can't
fit its required BW to the available link BW even though the limitation
may be resolved by reducing the BW requirement of other pipes.
To improve the above this patch adds helper functions checking the
overall BW limits after all CRTC states have been computed. If the check
fails the maximum link bpp for a selected pipe will be reduced and all
the CRTC states will be recomputed until either the overall BW limit
check passes, or further bpp reduction is not possible (because all
pipes/encoders sharing the link BW reached their minimum link bpp).
Atm, the MST encoder allocates twice the required BW for YUV420 format
streams. A follow-up patchset will fix that, add a code comment about
this.
This change prepares for upcoming patches enabling the above BW
management on FDI and MST links.
v2:
- Rename intel_crtc_state::max_link_bpp to max_link_bpp_x16 and
intel_link_bw_limits::max_bpp to max_bpp_x16. (Jani)
v3:
- Add the helper functions in a separate patch. (Ville)
- Add the functions to intel_link_bw.c instead of intel_atomic.c (Ville)
- Return -ENOSPC instead of -EINVAL to userspace in case of a link BW
limit failure.
v4:
- Make intel_atomic_check_config() static.
v5: (Ville)
- Rename intel_link_bw_limits::min_bpp_pipes to min_bpp_reached_pipes

Computing the non-DSC mode link config is redundant once it's determined
that DSC will be needed, so skip computing it. In a follow-up patch this

Normally we could be in a deep PkgC state all the way up to the
point when DSB starts its execution at the transcoders undelayed
vblank. The DSB will then have to wait for the hardware to
wake up before it can execute anything. This will waste a huge
chunk of the vblank time just waiting, and risks the DSB execution
spilling into the vertical active period. That will be very bad,
especially when programming the LUTs as the anti-collision logic
will cause DSB to corrupt LUT writes during vertical active.
To avoid these problems we can instruct the DSB to pre-wake the
display engine on a specific scanline so that everything will
be 100% ready to go when we hit the transcoder's undelayed vblank.
One annoyance is that the scanline is specified as just that,
a single scanline. So if we happen to start the DSB execution
after passing said scanline no DEwake will happen and we may drop
back into some PkgC state before reaching the transcoder's undelayed
vblank. To prevent that we'll use the "force DEwake" bit to manually
force the display engine to stay awake. We'll then have to clear
the force bit again after the DSB is done (the force bit remains
effective even when the DSB is otherwise disabled).

We want to start the DSB execution from the transcoder's undelayed
vblank, so in order to guarantee atomicity with the all the other
mmio register writes we need to evade both vblanks.
Note that currently we don't add any vblank delay, so this is
effectively a nop. But in the future when we start to program
double buffered registers from the DSB we'll need to delay the
pipe's vblank to provide the register programming "window2"
for the DSB.

Loading LUTs with the DSB outside of vblank doesn't really
work due to the palette anti-collision logic. Apparently the
DSB register writes don't get stalled like CPU mmio writes
do and instead we end up corrupting the LUT entries. Disabling
the anti-collision logic would allow us to successfully load
the LUT outside of vblank, but presumably that risks the LUT
reads from the scanout (temporarily) getting corrupted data
from the LUT instead.
The anti-collision logic isn't active during vblank so that
is when we can successfully load the LUT with the DSB. That is
what we want to do anyway to avoid tearing.

Differently from previous version, Xe2_LPD groups all port AUX interrupt
bits into PICA interrupt registers.
While at it, drop some trailing newlines.

The address of CTL and DATA registers for DP AUX were changed in Xe2_LPD:
now they are all in a single range, with CH_A and CH_B coming right after
the USBC instances. Like was done when moving registers to PICA, use
a helper macro to remap the ch passed to an index that can be used to
calculate the right offset.

XELPDP_DP_AUX_CH_CTL() and XELPDP_DP_AUX_CH_DATA() use 2 ranges. Prefer
using _PICK_EVEN_2RANGES() over PICK().

Fix some whitespace issues for register definitions and keep the defines
for DP_AUX_CH_CTL and DP_AUX_CH_DATA in the right place: together with
the bit definition.
While at it add a TODO entry that those defines shouldn't be using an
implicit dev_priv.

Since Xe2LPD technically has FlatCCS, it doesn't have AuxCCS registers
like PLANE_AUX_DIST. However we currently have HAS_FLAT_CCS hardcoded
to 0 since compression isn't ready; we need to make sure this doesn't
cause the display code to go back to trying to write this register.

We now start calculating relative plane data rate for cursor plane as
well, as instructed by BSpec and also treat cursor plane same way as
other planes, when doing allocation, i.e not using fixed allocation for
cursor anymore.
