33e7a97510 drm/i915/xelpd: First stab at DPT support
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?

7c653e15e2 drm/i915: Reorder skl+ scaler vs. plane updates
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...

e7c46e43bd drm/i915: Nuke display error state
I doubt anyone has used the display error state since CS flips
went the way of the dodo. Just nuke it.

It might be semi interesting to have something like this for
FIFO underruns and the like, but as it stands this wouldn't
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
accessing something with the relevant power well already
disabled.

7a6e95f375 drm/i915: Simplify CCS and UV plane alignment handling
We can handle the surface alignment of CCS and UV color planes for all
modifiers at one place, so do this. An AUX color plane can be a CCS or a
UV plane, use only the more specific query functions and remove
is_aux_plane() becoming redundant.

While at it add a TODO for linear UV color plane alignments. The spec
requires this to be stride-in-bytes * 64 on all platforms, whereas the
driver uses an alignment of 4k for gen<12 and 256k for gen>=12 for
linear UV planes.

v2:
- Restore previous alignment for linear UV surfaces.

93e7e61eb4 drm/i915/display: rename display version macros
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:

	@@ expression dev_priv, E1; @@
	- !IS_DISPLAY_VER(dev_priv, E1)
	+ DISPLAY_VER(dev_priv) != E1

	@@ expression dev_priv, E1; @@
	- IS_DISPLAY_VER(dev_priv, E1)
	+ DISPLAY_VER(dev_priv) == E1

	@@ expression dev_priv, from, until; @@
	- IS_DISPLAY_RANGE(dev_priv, from, until)
	+ IS_DISPLAY_VER(dev_priv, from, until)

a4606d4595 drm/i915: Add support for FBs requiring a POT stride alignment
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.

v2:
- Simplify plane_view_dst_stride(). (Ville)
- Pass pitch_tiles as unsigned int.
v3:
- Drop unintentional s/plane_state->rotation/plane_config->rotation/

ee456a4ca5 drm/i915: Simplify copying the FB view state to the plane state
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.

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()).

cc41b0fddb drm/i915: Fix rotation setup during plane HW readout
The HW plane state is cleared and inited after we store the rotation to
it, so store it instead to the uapi state to match what we do with all
other plane state until intel_plane_copy_uapi_to_hw_state() is called.

Rotation for initial FBs is not supported atm, but let's still fix the
plane state setup here.

While at it remove the redundant intel_state->uapi.src/dst init, which
will be done in intel_plane_copy_uapi_to_hw_state().

67f6f52af4 drm/i915: Stop adding planes to the commit needlessly
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.

02b64a4a0c drm/i915: Reject more ioctls for userptr, v2.
There are a couple of ioctl's related to tiling and cache placement,
that make no sense for userptr, reject those:
- i915_gem_set_tiling_ioctl()
    Tiling should always be linear for userptr. Changing placement will
    fail with -ENXIO.
- i915_gem_set_caching_ioctl()
    Userptr memory should always be cached. Changing caching mode will
    fail with -ENXIO.
- i915_gem_set_domain_ioctl()
    Still temporarily allowed to work as intended, it's used to check
    userptr validity. With the reworked userptr code, it will keep
    working for this usecase.

This plus the previous changes have been tested against beignet
by using its own unit tests, and intel-video-compute by using
piglit's opencl tests.

Changes since v1:
- set_domain was apparently used in iris for checking userptr validity,
  keep it working as intended.

GLK has always been a bit of a special case since it reports INTEL_GEN()

that we also need to switch any code that matches gen10 today but *not*

aaca50ef45 drm/i915: Extend icl_sanitize_encoder_pll_mapping() to all DDI platforms
Now that all the encoder clock stuff is uniformly abstracted
for all hsw+ platforms, let's extend icl_sanitize_encoder_pll_mapping()
to cover all of them.

Not sure there is a particular benefit in doing so, but less special
cases always makes me happy.

351221ffc5 drm/i915: Move DDI clock readout to encoder->get_config()
Move the *_get_ddi_pll() stuff into the encodet->get_config() hook.
There it neatly sits next to the matching .{enable,disable}_clock()
functions.

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
approach, but that would require a fairly substantial rework of the
DPLL ID handling. So leave it for later.

d0f1bfc615 drm/i915: Use pipes instead crtc indices in PLL state tracking
All the other places we have use pipes instead of crtc indices
when tracking resource usage. Life is easier when we do it
the same way always, so switch the dpll mgr to using pipes as
well. Looks like it was actually mixing these up in some cases
so it would not even have worked correctly except when the
device has a contiguous set of pipes starting from pipe A.
Granted, that is the typical case but supposedly it may not
always hold on modern hw.

7d3d8f853c drm/i915: Do intel_dpll_readout_hw_state() after encoder readout
The clock readout for DDI encoders needs to moved into the encoders.
To that end intel_dpll_readout_hw_state() needs to happen after
the encoder readout as otherwise it can't correctly populate
the PLL crtc_mask/active_mask bitmasks.

v2: Populate DPLL ref clocks before the encoder->get_config()

e43539f87a drm/i915: Move pipe enable/disable tracepoints to intel_crtc_vblank_{on,off}()
On platforms/outputs without a working frame counter we rely
on the vblank code to cook up the frame counter from the timestamps.
That requires that vblank support is enabled. Thus we need to
move the pipe enable/disable tracepoints to the other side
of the drm_vblank_{on,off}() calls. There shouldn't really be
much happening between these old and new call sites so the
tracepoints should still provide reasonable data.

The alternative would be to give up on having the frame counter
values in the trace which would render the tracepoints more or
less pointless.

v2: Missed one case in intel_ddi_post_disable()
    Drop the now useless i915_trace.h includes
