7785ae0b51 drm/i915: Don't include intel_de.h from intel_display_types.h
Hoist the intel_de.h include from intel_display_types.h one
level up. I need this in order to untangle the include order
so that I can add tracepoints into intel_de.h.

This little cocci script did most of the work for me:

61169987c4 drm/i915: Unify the FB and plane state view information into one struct
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.

v2:
- Make the patch have _no functional change_.
  (fix skl_check_nv12_aux_surface() and skl_check_main_surface()).
- s/i915_color_plane_view::pitch/stride/ (Ville)

cb80705549 drm/i915: Limit plane stride to below TILEOFF.x limit
Limit pre-skl plane stride to below 4k or 8k pixels (depending on
the platform). We do this in order guarantee that TILEOFF/OFFSET.x
does not get too big.

Currently this is not a problem as we align SURF to 4k, and so
TILEOFF/OFFSET only have to deal with a single tile's worth of
pixels. But for async flips we're going to have to bump SURF
alignment to 256k, and thus we can no longer guarantee
TILEOFF/OFFSET.x will stay within acceptable bounds. We can avoid
this by borrowing a trick from the skl+ code and limit the max
plane stride to whatever value we can fit into TILEOFF/OFFSET.x.

The slight downside is that we may end up doing GTT remapping in
a few more cases where previously we did not have to. But since
that will only happen with huge buffers I'm not really concerned
about it.

fed3875720 drm/i915/display: Prevent double YUV range correction on HDR planes
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.

68fd1faa92 drm/i915: Reuse the async_flip() hook for the async flip disable w/a
On some platforms we need to trigger an extra async flip with
the async flip bit disabled, and then wait for the next vblank
until the async flip bit off state will actually latch.

Currently the w/a is just open coded for skl+ universal planes.
Instead of doing that lets reuse the .async_flip() hook for this
purpose since it needs to write the exact same set of registers.
In order to do this we'll just have the caller pass in the state
of the async flip bit explicitly.

Set up the async flip PLANE_CTL bit directly in the
.async_flip() hook. Neither .update_plane() nor .disable_plane()
ever need to set this so having it done by skl_plane_ctl_crtc()
is rather pointless.

829270e455 drm/i915/display: Record the plane update times for debugging
Since we try and estimate how long we require to update the registers to
perform a plane update, it is of vital importance that we measure the
distribution of plane updates to better guide our estimate. If we
underestimate how long it takes to perform the plane update, we may
slip into the next scanout frame causing a tear. If we overestimate, we
may unnecessarily delay the update to the next frame, causing visible
jitter.

Replace the warning that we exceed some arbitrary threshold for the
vblank update with a histogram for debugfs.

v2: Add a per-crtc debugfs entry so that the information is easier to
extract when testing individual CRTC, and so that it can be reset before
a test.

v3: Flip the graph on its side; creates space to label the time axis.

c33298cb34 drm/i915/tgl: Fix stepping WA matching
TGL made stepping a litte mess, workarounds refer to the stepping of
the IP(GT or Display) not of the GPU stepping so it would already
require the same solution as used in commit 96c5a15f9f39
("drm/i915/kbl: Fix revision ID checks").
But to make things even more messy it have a different IP stepping
mapping between SKUs and the same stepping revision of GT do not match
the same HW between TGL U/Y and regular TGL.

So it was required to have 2 different macros to check GT WAs while
for Display we are able to use just one macro that uses the right
revids table.

All TGL workarounds checked and updated accordingly.

v2:
- removed TODO to check if WA 14010919138 applies to regular TGL.
- fixed display stepping in regular TGL (Anusha)

as TGL.  However the NV12 Y-plane support moves down to the new top two
planes and now only the bottom three planes can be used for NV12 UV.

9e859eb9d0 drm/i915/vgpu: improve vgpu abstractions
Add intel_vgpu_register() abstraction, rename i915_detect_vgpu() to
intel_vgpu_detect() to match other function naming, un-inline
intel_vgpu_active(), intel_vgpu_has_full_ppgtt() and
intel_vgpu_has_huge_gtt() to reduce header interdependencies.

The i915_vgpu.[ch] filename and intel_vgpu_ prefix discrepancy remains.

7a9ccdd1e0 drm/i915: Use intel_plane_data_rate for min_cdclk calculation
There seems to be a bit of confusing redundancy in a way, how
plane data rate/min cdclk are calculated.
In fact both min cdclk, pixel rate and plane data rate are all
part of the same formula as per BSpec.

However currently we have intel_plane_data_rate, which is used
to calculate plane data rate and which is also used in bandwidth
calculations. However for calculating min_cdclk we have another
piece of code, doing almost same calculation, but a bit differently
and in a different place. However as both are actually part of same
formula, probably would be wise to use plane data rate calculations
as a basis anyway, thus avoiding code duplication and possible bugs
related to this.

Another thing is that I've noticed that during min_cdclk calculations
we account for plane scaling, while for plane data rate, we don't.
crtc->pixel_rate seems to account only for pipe ratio, however it is
clearly stated in BSpec that plane data rate also need to account
plane ratio as well.

So what this commit does is:
- Adds a plane ratio calculation to intel_plane_data_rate
- Removes redundant calculations from skl_plane_min_cdclk which is
  used for gen9+ and now uses intel_plane_data_rate as a basis from
  there as well.

v2: - Don't use 64 division if not needed(Ville Syrjälä)
    - Now use intel_plane_pixel_rate as a basis for calculations both
      at intel_plane_data_rate and skl_plane_min_cdclk(Ville Syrjälä)

v3: - Again fix the division macro
    - Fix plane_pixel_rate to pixel_rate at intel_plane_pixel_rate
      callsites

v4: - Renamed skl_plane_ratio function back(Ville Syrjälä)

v5: - Don't precalculate plane pixel rate for invisible plane,
      check for visibility first, as in invisible case it will
      have dst_w and dst_h equal to zero, causing divide error.

v6: - Removed useless warn in intel_plane_pixel_rate(Ville Syrjälä)
    - Fixed alignment in intel_plane_data_rate(Ville Syrjälä)
    - Changed pixel_rate type to be unsigned int in
      skl_plane_min_cdclk(Ville Syrjälä)

dea2ecd12b drm/i915: Fix 90/270 degree rotated RGB565 src coord checks
Supposedly both src coordinates have to even when doing 90/270
degree rotation with RGB565. This is definitely true for the
X coordinate (we just get a black screen when it is odd). My
experiments didn't show any misbehaviour with an odd
Y coordinate, but let's trust the spec and reject that one
as well.

v2: Ignore ccs hsub/vsub
v3: Clarify the CCS special (Maarten)
    Deal with tgl+ CCS modifiers where we
    do need to look at hsub/vsub
