AuxCCS framebuffers don't work on Xe driver hence disable them
from plane capabilities until they are fixed. FlatCCS framebuffers
work and they are left enabled. CCS is left untouched for i915

On MTL the GOP (for whatever reason) likes to bind its framebuffer
high up in the ggtt address space. This can conflict with whatever
ggtt_reserve_guc_top() is trying to do, and the result is that
ggtt_reserve_guc_top() fails and then we proceed to explode when
trying to tear down the driver. Thus far I haven't analyzed what
causes the actual fireworks, but it's not super important as even
if it didn't explode we'd still fail the driver load and the user
would be left with an unusable GPU.
To remedy this (without having to figure out exactly what
ggtt_reserve_guc_top() is trying to achieve) we can attempt to
relocate the BIOS framebuffer to a lower ggtt address. We can do
this at this early point in driver init because nothing else is
supposed to be clobbering the ggtt yet. So we simply change where
in the ggtt we pin the vma, the original PTEs will be left as is,
and the new PTEs will get written with the same dma addresses.
The plane will keep on scanning out from the original PTEs until
we are done with the whole process, and at that point we rewrite
the plane's surface address register to point at the new ggtt
address.
Since we don't need a specific ggtt address for the plane
(apart from needing it to land in the mappable region for
normal stolen objects) we'll just try to pin it without a fixed
offset first. It should end up at the lowest available address
(which really should be 0 at this point in the driver init).
If that fails we'll fall back to just pinning it exactly to the
origianal address.
To make sure we don't accidentlally pin it partially over the
original ggtt range (as that would corrupt the original PTEs)
we reserve the original range temporarily during this process.
v2: Try to pin explicitly to ggtt offset 0 as otherwise DG2 puts it
even higher (atm we have no PIN_LOW flag to force it low)
v3: "fix" xe

Several workarounds are guarded by IS_MTL_GRAPHICS_STEP. However none
of these workarounds are actually tied to MTL as a platform; they only
relate to the Xe_LPG graphics IP, regardless of what platform it appears
in. At the moment MTL is the only platform that uses Xe_LPG with IP
versions 12.70 and 12.71, but we can't count on this being true in the
future. Switch these to use a new IS_GFX_GT_IP_STEP() macro instead
that is purely based on IP version. IS_GFX_GT_IP_STEP() is also
GT-based rather than device-based, which will help prevent mistakes
where we accidentally try to apply Xe_LPG graphics workarounds to the
Xe_LPM+ media GT and vice-versa.

Starting with MTL, there will be two GT-tiles, a render and media
tile. PXP as a service for supporting workloads with protected
contexts and protected buffers can be subscribed by process
workloads on any tile. However, depending on the platform,
only one of the tiles is used for control events pertaining to PXP
operation (such as creating the arbitration session and session
tear-down).
PXP as a global feature is accessible via batch buffer instructions
on any engine/tile and the coherency across tiles is handled implicitly
by the HW. In fact, for the foreseeable future, we are expecting this
single-control-tile for the PXP subsystem.
In MTL, it's the standalone media tile (not the root tile) because
it contains the VDBOX and KCR engine (among the assets PXP relies on
for those events).
Looking at the current code design, each tile is represented by the
intel_gt structure while the intel_pxp structure currently hangs off the
intel_gt structure.
Keeping the intel_pxp structure within the intel_gt structure makes some
internal functionalities more straight forward but adds code complexity to
code readability and maintainibility to many external-to-pxp subsystems
which may need to pick the correct intel_gt structure. An example of this
would be the intel_pxp_is_active or intel_pxp_is_enabled functionality
which should be viewed as a global level inquiry, not a per-gt inquiry.
That said, this series promotes the intel_pxp structure into the
drm_i915_private structure making it a top-level subsystem and the PXP
subsystem will select the control gt internally and keep a pointer to
it for internal reference.
This promotion comes with two noteworthy changes:
1. Exported pxp functions that are called by external subsystems
(such as intel_pxp_enabled/active) will have to check implicitly
if i915->pxp is valid as that structure will not be allocated
for HW that doesn't support PXP.
2. Since GT is now considered a soft-dependency of PXP we are
ensuring that GT init happens before PXP init and vice versa
for fini. This causes a minor ordering change whereby we previously
called intel_pxp_suspend after intel_uc_suspend but now is before
i915_gem_suspend_late but the change is required for correct
dependency flows. Additionally, this re-order change doesn't
have any impact because at that point in either case, the top level
entry to i915 won't observe any PXP events (since the GPU was
quiesced during suspend_prepare). Also, any PXP event doesn't
really matter when we disable the PXP HW (global GT irqs are
already off anyway, so even if there was a bug that generated
spurious events we wouldn't see it and we would just clean it
up on resume which is okay since the default fallback action
for PXP would be to keep the sessions off at this suspend stage).
Changes from prior revs:
v11: - Reformat a comment (Tvrtko).
v10: - Change the code flow for intel_pxp_init to make it more
cleaner and readible with better comments explaining the
difference between full-PXP-feature vs the partial-teelink
inits depending on the platform. Additionally, only do
the pxp allocation when we are certain the subsystem is
needed. (Tvrtko).
v9: - Cosmetic cleanups in supported/enabled/active. (Daniele).
- Add comments for intel_pxp_init and pxp_get_ctrl_gt that
explain the functional flow for when PXP is not supported
but the backend-assets are needed for HuC authentication
(Daniele and Tvrtko).
- Fix two remaining functions that are accessible outside
PXP that need to be checking pxp ptrs before using them:
intel_pxp_irq_handler and intel_pxp_huc_load_and_auth
(Tvrtko and Daniele).
- User helper macro in pxp-debugfs (Tvrtko).
v8: - Remove pxp_to_gt macro (Daniele).
- Fix a bug in pxp_get_ctrl_gt for the case of MTL and we don't
support GSC-FW on it. (Daniele).
- Leave i915->pxp as NULL if we dont support PXP and in line
with that, do additional validity check on i915->pxp for
intel_pxp_is_supported/enabled/active (Daniele).
- Remove unncessary include header from intel_gt_debugfs.c
and check drm_minor i915->drm.primary (Daniele).
- Other cosmetics / minor issues / more comments on suspend
flow order change (Daniele).
v7: - Drop i915_dev_to_pxp and in intel_pxp_init use 'i915->pxp'
through out instead of local variable newpxp. (Rodrigo)
- In the case intel_pxp_fini is called during driver unload but
after i915 loading failed without pxp being allocated, check
i915->pxp before referencing it. (Alan)
v6: - Remove HAS_PXP macro and replace it with intel_pxp_is_supported
because : [1] introduction of 'ctrl_gt' means we correct this
for MTL's upcoming series now. [2] Also, this has little impact
globally as its only used by PXP-internal callers at the moment.
- Change intel_pxp_init/fini to take in i915 as its input to avoid
ptr-to-ptr in init/fini calls.(Jani).
- Remove the backpointer from pxp->i915 since we can use
pxp->ctrl_gt->i915 if we need it. (Rodrigo).
v5: - Switch from series to single patch (Rodrigo).
- change function name from pxp_get_kcr_owner_gt to
pxp_get_ctrl_gt.
- Fix CI BAT failure by removing redundant call to intel_pxp_fini
from driver-remove.
- NOTE: remaining open still persists on using ptr-to-ptr
and back-ptr.
v4: - Instead of maintaining intel_pxp as an intel_gt structure member
and creating a number of convoluted helpers that takes in i915 as
input and redirects to the correct intel_gt or takes any intel_gt
and internally replaces with the correct intel_gt, promote it to
be a top-level i915 structure.
v3: - Rename gt level helper functions to "intel_pxp_is_enabled/
supported/ active_on_gt" (Daniele)
- Upgrade _gt_supports_pxp to replace what was intel_gtpxp_is
supported as the new intel_pxp_is_supported_on_gt to check for
PXP feature support vs the tee support for huc authentication.
Fix pxp-debugfs-registration to use only the former to decide
support. (Daniele)
- Couple minor optimizations.
v2: - Avoid introduction of new device info or gt variables and use
existing checks / macros to differentiate the correct GT->PXP
control ownership (Daniele Ceraolo Spurio)
- Don't reuse the updated global-checkers for per-GT callers (such
as other files within PXP) to avoid unnecessary GT-reparsing,
expose a replacement helper like the prior ones. (Daniele).
v1: - Add one more patch to the series for the intel_pxp suspend/resume
for similar refactoring

{display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h
-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new
includes all over the place.
Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h
and only include the specific registers at each place.
Also some places actually needed i915_irq.h too.

Since we now have the bigjoiner_pipes bitmask the boolean
is redundant. Get rid of it.
Also, populating bigjoiner_pipes already during
encoder->compute_config() allows us to use it much earlier
during the state calculation as well. The initial aim is
to use it in intel_crtc_compute_config().
v2: Move the hweight(bigjoiner_pipes) stuff to a later patch

Instead of just having the pipe_src_{w,h} let's use a full
drm_rect for it. This will be particularly useful to astract
away some bigjoiner details.
v2: No hweight() stuff yet

On icl+ all plane registers are armed by PLANE_SURF, so we can
move almost everything over into the update_noarm() hook.
The PLANE_CTL write has to stay in the icl_update_arm() hook though
as it still exhibits the somewhat annoying self-arming behaviour
when the plane transitioning from disabled to enabled.
We could either do a full split for skl+ vs. icl+, or we could try
some other kind of split where we'd eg. keep most things in the skl+
functions and call them from the icl+ functions. I think a full split
is probably the cleaner approach since we've anyway accumulated quite
a bit of icl+ specific things, so that is what I opted to do.
