The DDI naming template for display version 12 went A-C, TC1-TC6. With
XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4.
The XE_LPD design keeps the register offsets and bitfields relating to
the TC outputs in the same location they were previously. The new "D"
and "E" outputs now take the locations that were previously used by TC5
and TC6 outputs, or what we would have considered to be outputs "H" and
"I" under the legacy lettering scheme.
For the most part everything will just work as long as we initialize the
output with the proper 'enum port' value. However we do need to take
care to pick the correct AUX channel when parsing the VBT (e.g., a
reference to 'AUX D' is actually asking us to use the 8th aux channel,
not the fourth). We should also make sure that our encoders and aux
channels are named appropriately so that it's easier to correlate driver
debug messages with the bspec instructions.
v2:
- Update handling of TGL_TRANS_CLK_SEL_PORT. (Jose)
v3:
- Add hpd_pin to handle outputs D and E (Jose)
- Fixed conversion of BIOS port to aux ch for TC ports (Jose)

Direction on gen9+ was to stop reading the straps and only rely on the
VBT for marking the port presence. This happened while dealing with
WaIgnoreDDIAStrap and instead of using it as a WA, it should now be the
normal flow. See commit 885d3e5b6f ("drm/i915/display: fix comment on
skl straps").
For gen 10 it's hard to say if this will work or not since I can't test
it, so leave it with the same behavior as before.
For PCH_TGP we should still rely on the VBT to make ports E and F not
available.
v2 (Ville):
- use display ver >= 9 to make it consistent with the rest of the
driver instead of checking for == 9
- also handle CNL and only initialize port F if it is
IS_CNL_WITH_PORT_F. Eventually CNL may be removed, but while it
isn't let's keep it consistent everywhere

Alderlake-P have a new stride restriction when using DPT and it is used
by non linear framebuffers. Stride needs to be a power of two to take
full DPT rows, but stride is a parameter set by userspace.
What we could do is use a fake stride when doing DPT allocation so
HW requirements are met and userspace don't need to be changed to
met this power of two restrictions but this change will take a while
to be implemented so for now adding this restriction in driver to

Add support for DPT (display page table). DPT is a
slightly peculiar two level page table scheme used for
tiled scanout buffers (linear uses direct ggtt mapping
still). The plane surface address will point at a page
in the DPT which holds the PTEs for 512 actual pages.
Thus we require 1/512 of the ggttt address space
compared to a direct ggtt mapping.
We create a new DPT address space for each framebuffer and
track two vmas (one for the DPT, another for the ggtt).
TODO:
- Is the i915_address_space approaach sane?
- Maybe don't map the whole DPT to write the PTEs?
- Deal with remapping/rotation? Need to create a
separate DPT for each remapped/rotated plane I
guess. Or else we'd need to make the per-fb DPT
large enough to support potentially several
remapped/rotated vmas. How large should that be?

When scanning out NV12 if we at any time have the plane enabled
while the scaler is disabled we get a pretty catastrophic
underrun.
Let's reorder the operations so that we try to avoid that happening
even if our vblank evade fails and the scaler enable/disable and
the plane enable/disable get latched during two diffent frames.
This takes care of the most common cases. I suppose there is still
at least a theoretical possibility of hitting this if one plane
takes the scaler away from another plane before the second plane
had a chance to set up another scaler for its use. But that
is starting to get a bit complicated, especially since the plane
commit order already has to be carefully sequenced to avoid any
dbuf overlaps. So plugging this 100% may prove somewhat hard...

It might be semi interesting to have something like this for

provide a sufficient amount of information. So would need
an extensive rewrite anyway.
The lockless power well handling is also racy, so this could
just be contributing noise to test results if we end up

While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:
1) Why is the == comparison special that deserves a separate
macro instead of just getting the version and comparing directly
like is done for >, >=, <=?
2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
brevity. If we remove the current users of IS_DISPLAY_VER(), we
could actually repurpose it for a range check
With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.
So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:

Now that we've eliminated INTEL_GEN(), IS_GEN_RANGE(), etc. from the
display code, we should also kill off our use of the IS_GEN9_* macros
too. We'll do the conversion manually this time instead of using
Coccinelle since the most logical substitution can depend heavily on the
code context, and sometimes we can keep the code simpler if we make
additional adjustments such as swapping the order of if/else arms.

An upcoming platform has a restriction that the FB stride must be
power-of-two aligned. To support framebuffer layouts that are not in
this layout add a logic that pads the tile rows to the POT aligned size.
The HW won't read the padding PTEs, so these don't have to point to an
allocated address, or even have their valid flag set. So use a NULL PTE
instead for instance the scratch page, which is simple and keeps the SG
table compact.

Instead of copying separately the GTT remapped and color plane view info
from the FB to the plane state, do this by copying the whole
intel_fb_view struct. For this we make sure the FB view state is fully
inited (that is also including the view type) already during FB
creation, so this init is not required during atomic check time. This
also means the we don't need to reset the unused color plane info during
atomic check, as these are already reset during FB creation.
I noticed that initial FBs will only work atm if they are page aligned
(which BIOS most probably always ensures), but add a comment to sanitize
this part once. Also we won't disable the plane if
get_initial_plane_config() failed for some reason (for instance due to
unsupported rotation), add a TODO: comment for this too.

To allow the simplification of FB/plane view computation in the
follow-up patches, unify the corresponding state in the
intel_framebuffer and intel_plane_state structs into a new intel_fb_view
struct.
This adds some overhead to intel_framebuffer as the rotated view will
have now space for 4 color planes instead of the required 2 and it'll
also contain the unused offset for each color_plane info. Imo this is an
acceptable trade-off to get a simplified way of the remap computation.
Use the new intel_fb_view struct for the FB normal view as well, so (in
the follow-up patches) we can remove the special casing for normal view
calculation wrt. the calculation of remapped/rotated views. This also
adds an overhead to the intel_framebuffer struct, as the gtt remap info
and per-color plane offset/pitch is not required for the normal view,
but imo this is an acceptable trade-off as above. The per-color plane
pitch filed will be used by a follow-up patch, so we can retrieve the
pitch for each view in the same way.
No functional changes in this patch.

The dbuf bandwidth calculations don't need the planes to be
added to the state. Each plane's data rate has already been
precalculated and stored in the crtc state, and that with
the dbuf slice usage for each plane is all the dbuf bandwidth
code needs to figure out what the minimum cdclk is.
What we're trying to do here is make sure each plane recalculates
its minimum cdclk (ie. plane->min_cdclk()) on those platforms where
the number of active planes affects the result of said calculation.
Nothing to do with any dbuf cdclk requirements.
Not sure if we had stuff in slightly different order or what,
but at least in the current scheme this is not necessary.

There it neatly sits next to the matching .{enable,disable}_clock()

In order to avoid excessive boilerplate I changed the behaviour
such that all platforms now do the readout via
crtc_state->port_dpll[].
ICL+ TC is still a bit special due to TBTPLL not having a functional
.get_freq(). Should probably change that by adopting the LCPLL

ilk+ planes get notably unhappy when the plane x+w exceeds

always aligned SURF to the closest tile boundary so the
x offset never got particularly large. But now with async
flips we have to align to 256KiB instead and thus this

On ilk/snb/ivb it looks like the accesses just wrap
early to the next tile row when scanout goes past the
SURF+n*stride boundary, hsw/bdw suffer more heavily and
start to underrun constantly. i965/g4x appear to be immune.
vlv/chv I've not yet checked.
Let's borrow another trick from the skl+ code and search
backwards for a better SURF offset in the hopes of getting the
x offset below the limit. IIRC when I ran into a similar issue
on skl years ago it was causing the hardware to fall over
pretty hard as well.
And let's be consistent and include i965/g4x in the check
as well, just in case I just got super lucky somehow when
I wasn't able to reproduce the issue. Not that it really
matters since we still use 4k SURF alignment for i965/g4x
anyway.

intel_init_audio_hooks() sets up hooks in the display struct and only
makes sense when we have display. Move it inside
intel_init_display_hooks() so it isn't called when we don't have

provide us with a STRAP config register to read from for initializing DDI
B, C, and D detection. So, workaround this by hard-coding our strap config

It is a preliminary work for supporting multiple EDP PSR and
DP PanelReplay. And it refactors singleton PSR to Multi Transcoder
supportable PSR.
And this moves and renames the i915_psr structure of drm_i915_private's to
intel_dp's intel_psr structure.
It also causes changes in PSR interrupt handling routine for supporting
multiple transcoders. But it does not change the scenario and timing of
enabling and disabling PSR. And it not support multiple pipes with
a single transcoder PSR case yet.

Add support for async flips on vlv/chv. Unlike all the other
platforms vlv/chv do not use the async flip bit in DSPCNTR and
instead we select between async vs. sync flips based on the
surface address register. The normal DSPSURF generates sync
flips DSPADDR_VLV generates async flips. And as usual the
interrupt bits are different from the other platforms.

Implement async flip support for BDW. The implementation is
similar to the skl+ code. And just like skl/bxt/glk bdw also
needs the disable w/a, thus we need to plumb the desired state
of the async flip all the way down to i9xx_plane_ctl_crtc().
According to the spec we do need to bump the surface alignment
to 256KiB for this. Async flips require an X-tiled buffer so
we don't have to worry about linear.

Prevent the ICL HDR plane pipeline from performing YUV color range
correction twice when the input is in limited range. This is done by
removing the limited-range code from icl_program_input_csc().
Before this patch the following could happen: user space gives us a YUV
buffer in limited range; per the pipeline in [1], the plane would first
go through a "YUV Range correct" stage that expands the range; the plane
would then go through the "Input CSC" stage which would also expand the
range because icl_program_input_csc() would use a matrix and an offset
that assume limited-range input; this would ultimately cause dark and
light colors to appear darker and lighter than they should respectively.
This is an issue because if a buffer switches between being scanned out
and being composited with the GPU, the user will see a color difference.
If this switching happens quickly and frequently, the user will perceive
this as a flickering.
