On FBC1 we can specify an arbitrary cfb stride. The hw will
simply throw away any compressed line that would exceed the
specified limit and keep using the uncompressed data instead.
Thus we can allow arbitrary compression limits.
The one thing we have to keep in mind though is that the cfb
stride is specified in units of 32B (gen2) or 64B (gen3+).
Fortunately X-tile is already 128B (gen2) or 512B (gen3+) wide
so as long as we limit outselves to the same 4x compression
limit that FBC2 has we are guaranteed to have a sufficiently
aligned cfb stride.

Apply the same 512 byte FBC segment alignment to glk+ as we use
on skl+. The only real difference is that we now have a dedicated
register for the FBC override stride. Not 100% sure which
platforms really need the 512B alignment, but it's easiest
to just do it on everything.
Also the hardware no longer seems to misclaculate the CFB stride
for linear, so we can omit the use of the override stride for
linear unless the stride is misaligned.

The code to calculate the cfb stride/size is a bit of mess.
The cfb size is getting calculated based purely on the plane
stride and plane height. That doesn't account for extra
alignment we want for the cfb stride. The gen9 override
stride OTOH is just calculated based on the plane width, and
it does try to make things more aligned but any extra alignment
added there is not considered in the cfb size calculations.
So not at all convinced this is working as intended. Additionally
the compression limit handling is split between the cfb allocation
code and g4x_dpfc_ctl_limit() (for the 16bpp case), which is just
confusing.
Let's streamline the whole thing:
- Start with the plane stride, convert that into cfb stride (cfb is
always 4 bytes per pixel). All the calculations will assume 1:1
compression limit since that will give us the max values, and we
don't yet know how much stolen memory we will be able to allocate
- Align the cfb stride to 512 bytes on modern platforms. This guarantees
the 4 line segment will be 512 byte aligned regardles of the final
compression limit we choose later. The 512 byte alignment for the
segment is required by at least some of the platforms, and just doing
it always seems like the easiest option
- Figure out if we need to use the override stride or not. For X-tiled
it's never needed since the plane stride is already 512 byte aligned,
for Y-tiled it will be needed if the plane stride is not a multiple
of 512 bytes, and for linear it's apparently always needed because the
hardware miscalculates the cfb stride as PLANE_STRIDE*512 instead of
the PLANE_STRIDE*64 that it use with linear.
- The cfb size will be calculated based on the aligned cfb stride to
guarantee we actually reserved enough stolen memory and the FBC hw
won't end up scribbling over whatever else is allocated in stolen
- The compression limit handling we just do fully in the cfb allocation
code to make things less confusing
v2: Write the min cfb segment stride calculation in a more
explicit way to make it clear what is going on
v3: Remeber to update fbc->limit when changing to 16bpp

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 84030adb9e27 ("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:

At the moment CCS FB strides must be power-of-two sized, but a follow-up
change will add support remapping these FBs, allowing the FB passed in
by userspace to have a non-POT sized stride. For these remapped FBs we
can only remap the main surface, not the CCS surface. This means that
userspace has to always generate the CCS surface aligning to the POT
stride padded main surface (by setting up the CCS AUX pagetables
accordingly). Adjust the CCS surface stride check to enforce this.
No functional change.

The tile size for all surface types is 4 kbyte (or 2 kbyte on old
platforms), with the exception of the TGL/ADL CCS surface where the tile
size is 64 bytes. To be able to remap CCS FBs the CCS surface tile needs
to be defined as 4 kbyte as well (the granularity of GTT pages in a
remapped view).
The only place using the dimension of the 64 byte CCS area is the initial
check for the main vs. CCS plane origin coordinate match. To prepare for
adding support for remapping CCS FBs let's call the 64 byte CCS area a
'tile block' and add a helper to retrieve the dimensions for it.

128b/132b channel encoding has separate TPS1 and TPS2, although the DPCD
register values coincide with 8b/10b TPS1 and TPS2 values. Use 128b/132b
TPS2 for channel equalization.
v2: Use intel_dp_is_uhbr

Unfortunately, the DP 2.0 128b/132b DDI mode selection in the register
conflicts with FDI. Since we have to deal with both meanings in the same
code, for different platforms, clarify the macro name so we don't
forget.

The DP 2.0 128b/132b channel coding uses TX FFE presets instead of
vswing and pre-emphasis.

Extend the use of extended receiver cap at 0x2200 to cover
MAIN_LINK_CHANNEL_CODING_CAP in 0x2206, in case an implementation hides
the DP 2.0 128b/132b channel encoding cap.

The bw code equals link_rate / 0.27 Gbps only for 8b/10b link
rates. Handle DP 2.0 UHBR rates as special cases, though this is not
pretty.

Wa_16014451276 fixes the starting coordinate for PSR2 selective
updates. CHICKEN_TRANS definition of the workaround bit has a wrong
name based on workaround definition and HSD.
Wa_14014971508 allows the screen to continue to be updated when
coming back from DC5/DC6 and SF_SINGLE_FULL_FRAME bit is not kept
set in PSR2_MAN_TRK_CTL.
Wa_16012604467 fixes underruns when exiting PSR2 when it is in one
of its internal states.
Wa_14014971508 is still in pending status in BSpec but by
the time this is reviewed and ready to be merged it will be finalized.
v2:
- renamed register to ADLP_1_BASED_X_GRANULARITY
- added comment about all ADL-P supported panels being 1 based X
granularity

drm_atomic_helper_damage_iter_init() + drm_atomic_for_each_plane_damage()
returns the full plane area in case no damaged area was set by
userspace or it was discarted by driver.
This is important to fix the rendering of userspace applications that
does frontbuffer rendering and notify driver about dirty areas but do
not set any dirty clips.
With this we don't need to worry about to check and mark the whole
area as damaged in page flips.
Another important change here is the move of
drm_atomic_add_affected_planes() call, it needs to called late
otherwise the area of all the planes would be added to pipe_clip and
not saving power.

Not sure why but when moving the cursor fast it causes some artifacts
of the cursor to be left in the cursor path, adding some pixels above
the cursor to the damaged area fixes the issue, so leaving this as a
workaround until proper fix is found.
This is reproducile on TGL and ADL-P.
