drm/xe: Align all VRAM scanout buffers to 64k physical pages when needed.
For CCS formats on affected platforms, CCS can be used freely, but
display engine requires a multiple of 64k physical pages. No other
changes are needed.

At the BO creation time we don't know if the BO will be used for CCS
or not. If the scanout flag is set, and the BO is a multiple of 64k,
we take the safe route and force the physical alignment of 64k pages.

If the BO is not a multiple of 64k, or the scanout flag was not set
at BO creation, we reject it for usage as CCS in display. The physical
pages are likely not aligned correctly, and this will cause corruption
when used as FB.

The scanout flag and size being a multiple of 64k are used together
to enforce 64k physical placement.

VM_BIND is completely unaffected, mappings to a VM can still be aligned
to 4k, just like for normal buffers.

66a0f6b9f5 drm/xe/display: handle HPD polling in display runtime suspend/resume
In XE, display runtime suspend / resume routines are called only
if d3cold is allowed. This makes the driver unable to detect any
HPDs once the device goes into runtime suspend state in platforms
like LNL. Update the display runtime suspend / resume routines
to include HPD polling regardless of d3cold status.

While xe_display_pm_suspend/resume() performs steps during runtime
suspend/resume that shouldn't happen, like suspending MST and they
are missing other steps like enabling DC9, this patchset is meant
to keep the current behavior wrt. these, leaving the corresponding
updates for a follow-up

v2: have a separate function for display runtime s/r (Rodrigo)

drm/xe: Make xe_ggtt_node struct independent
In some rare cases, the drm_mm node cannot be removed synchronously
due to runtime PM conditions. In this situation, the node removal will
be delegated to a workqueue that will be able to wake up the device
before removing the node.

However, in this situation, the lifetime of the xe_ggtt_node cannot
be restricted to the lifetime of the parent object. So, this patch
introduces the infrastructure so the xe_ggtt_node struct can be
allocated in advance and freed when needed.

By having the ggtt backpointer, it also ensure that the init function
is always called before any attempt to insert or reserve the node
in the GGTT.

v3: - Use GF_NOFS for node allocation (CI)
    - Avoid ggtt argument, now that we have it inside the node (Lucas)

    - Avoid ggtt argument also on removal (missed case on v3) (Michal)

    - Return 0 instead of negative errno on a u32 addr. (Michal)

drm/xe: Encapsulate drm_mm_node inside xe_ggtt_node
The xe_ggtt component uses drm_mm to manage the GGTT.
The drm_mm_node is just a node inside drm_mm, but in Xe we use that
only in the GGTT context. So, this patch encapsulates the drm_mm_node
into a xe_ggtt's new struct.

This is the first step towards limiting all the drm_mm access
through xe_ggtt. The ultimate goal is to have a better control of
the node insertion and removal, so the removal can be delegated
to a delayed workqueue.

drm/xe/bmg: implement Wa_16023588340
This involves enabling l2 caching of host side memory access to VRAM
through the CPU BAR. The main fallout here is with display since VRAM
writes from CPU can now be cached in GPU l2, and display is never
coherent with caches, so needs various manual flushing.  In the case of
fbc we disable it due to complications in getting this to work
correctly (in a later patch).

cb8f81c175 drm/xe/display: Make display suspend/resume work on discrete
We should unpin before evicting all memory, and repin after GT resume.
This way, we preserve the contents of the framebuffers, and won't hang
on resume due to migration engine not being restored yet.

492be2a070 drm/xe/display: Match i915 driver suspend/resume sequences better
Suspend fbdev sooner, and disable user access before suspending to
prevent some races. I've noticed this when comparing xe suspend to
i915's.

Matches the following commits from i915:
24b412b1bf ("drm/i915: Disable intel HPD poll after DRM poll init/enable")
1ef28d86be ("drm/i915: Suspend the framebuffer console earlier during system suspend")
bd738d859e ("drm/i915: Prevent modesets during driver init/shutdown")

Thanks to Imre for pointing me to those commits.

Driver shutdown is currently missing, but I have some idea how to
implement it next.

1eda95cba9 drm/xe: Rename enable_display module param
The different approach used by xe regarding the initialization of
display HW has been proved a great addition for early driver bring up:
core xe can be tested without having all the bits sorted out on the
display side.

On the other hand, the approach exposed by i915-display is to *actively*
disable the display by programming it if needed, i.e. if it was left
enabled by firmware. It also has its use to make sure the HW is actually
disabled and not wasting power.

However having both the way it is in xe doesn't expose a good interface
wrt module params. From modinfo:

	disable_display:Disable display (default: false) (bool)
	enable_display:Enable display (bool)

Rename enable_display to probe_display to try to convey the message that
the HW is being touched and improve the module param description. To
avoid confusion, the enable_display is renamed everywhere, not only in
the module param. New description for the parameters:

	disable_display:Disable display (default: false) (bool)
	probe_display:Probe display HW, otherwise it's left untouched (default: true) (bool)

775d0adc01 drm/xe/fbdev: Limit the usage of stolen for LNL+
As per recommendation in the workarounds:
WA_22019338487

There is an issue with accessing Stolen memory pages due a
hardware limitation. Limit the usage of stolen memory for
fbdev for LNL+. Don't use BIOS FB from stolen on LNL+ and
assign the same from system memory.

v2: Corrected the WA Number, limited WA to LNL and
    Adopted XE_WA framework as suggested by Lucas and Matt.

v3: Introduced the waxxx_display to implement display side
    of WA changes on Lunarlake. Used xe_root_mmio_gt and
    avoid the for loop (Suggested by Lucas)

v4: Fixed some nits (Luca)

01570b4469 drm/xe/bmg: implement Wa_16023588340
This involves enabling l2 caching of host side memory access to VRAM
through the CPU BAR. The main fallout here is with display since VRAM
writes from CPU can now be cached in GPU l2, and display is never
coherent with caches, so needs various manual flushing.  In the case of
fbc we disable it due to complications in getting this to work
correctly (in a later patch).

drm/xe/lnl: Apply Wa_22019338487
This WA requires us to limit media GT frequency requests to a certain
cap value during driver load. Freq limits are restored after load
completes, so perf will not be affected during normal operations.

During normal driver operation, this WA requires dummy writes to media
offset 0x380D8C after every ~63 GGTT writes. This will ensure completion
of the LMEM writes originating from Gunit.

During driver unload(before FLR), the WA requires that we set requested
frequency to the cap value again.

v3: Do not use WA number in function name. Call WA wrapper from xe_device.
Rename some variables, check for locks in the correct function (Rodrigo).
Ensure reset path is also covered for this WA.

v4: Fix BAT failure

v5: Add a function pointer for ggtt_ops (Michal W)

v6: Fix name collision and use static function (Rodrigo)

195b7a0d2e drm/i915: Introduce the plane->min_alignment() vfunc
Different hardware generations have different scanout alignment
requirements. Introduce a new vfunc that will allow us to
make that distinction without horrible if-ladders.

For now we directly plug in the existing intel_surf_alignment()
and intel_cursor_alignment() functions.

For fbdev we (temporarily) introduce intel_fbdev_min_alignment()
that simply queries the alignment from the primary plane of
the first crtc.

TODO: someone will need to fix xe's alignment handling

Use the suspend encoders helper which is also used by the i915 driver.
This fixes an issue in the xe driver where the encoder
suspend_complete() hook is not called and was an overlook when this hook
was added in commit b61fad5f7e ("drm/i915/tc: Call TypeC port
flush_work/cleanup without modeset locks held") for i915, but not added
to the xe driver (which was still in a separate source tree at the above

drm/xe: Prepare display for D3Cold
Prepare power-well and DC handling for a full power
lost during D3Cold, then sanitize it upon D3->D0.
Otherwise we get a bunch of state mismatch.

Ideally we could leave DC9 enabled and wouldn't need
to move DC9->DC0 on every runtime resume, however,
the disable_DC is part of the power-well checks and
intrinsic to the dc_off power well. In the future that
can be detangled so we can have even bigger power savings.
But for now, let's focus on getting a D3Cold, which saves
much more power by itself.

v2: create new functions to avoid full-suspend-resume path,
which would result in a deadlock between xe_gem_fault and the
modeset-ioctl.

v3: Only avoid the full modeset to avoid the race, for a more
robust suspend-resume.

6907d4fa5e drm/xe: Nuke xe's copy of intel_fbdev_fb.h

copy of intel_fbdev_fb.h. The xe copy actually only gets included
by xe's intel_fbdev_fb.c, and the i915 copy by everyone else,
include intel_fbdev.c which is the actual caller of the
functions declared in the header.

This means the xe and i915 headers are free to define/declare
completely incompatible things and the build would still succeed
as long as the symbol names match.

That is not a good thing, so let's nuke xe's copy of the header
so that everyone will use the same header, and be forced to
agree on the same API/ABI.

b55f3bbab8 drm/{i915, xe}: Implement fbdev emulation as in-kernel client
Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to intel_fbdev_setup() after i915 has registered its
DRM device. Just like similar code in other drivers, i915 fbdev
emulation now acts like a regular DRM client. Do the same for xe.

The fbdev client setup consists of the initial preparation and the
hot-plugging of the display. The latter creates the fbdev device
and sets up the fbdev framebuffer. The setup performs display
hot-plugging once. If no display can be detected, DRM probe helpers
re-run the detection on each hotplug event.

A call to drm_client_dev_unregister() releases all in-kernel clients
automatically. No further action is required within i915. If the fbdev
framebuffer has been fully set up, struct fb_ops.fb_destroy implements
the release. For partially initialized emulation, the fbdev client
reverts the initial setup. Do the same for xe and remove its call to
intel_fbdev_fini().

v8:
- setup client in intel_display_driver_register (Jouni)
- mention xe in commit message

v7:

Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display.

The DRM core calls both, the old callbacks and the new client
helpers, from the same places. The new functions perform the same
operation as before, so there's no change in functionality.

Fox xe, remove xe_display_last_close(), which restored the fbdev
display. As with i915, the DRM core's drm_lastclose() performs
this operation automatically.

62742d1266 drm/xe: Normalize bo flags macros
The flags stored in the BO grew over time without following
much a naming pattern. First of all, get rid of the _BIT suffix that was
banned from everywhere else due to the guideline in
drivers/gpu/drm/i915/i915_reg.h that xe kind of follows:

	Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.

Here the flags aren't for a register, but it's good practice to keep it
consistent.

Second divergence on names is the use or not of "CREATE". This is
because most of the flags are passed to xe_bo_create*() family of
functions, changing its behavior. However, since the flags are also
stored in the bo itself and checked elsewhere in the code, it seems
better to just omit the CREATE part.

With those 2 guidelines, all the flags are given the form
XE_BO_FLAG_<FLAG_NAME> with the following commands:

	git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i \
		-e "s/XE_BO_\([_A-Z0-9]*\)_BIT/XE_BO_\1/g" \
		-e 's/XE_BO_CREATE_/XE_BO_FLAG_/g'
	git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i -r \
		-e 's/XE_BO_(DEFER_BACKING|SCANOUT|FIXED_PLACEMENT|PAGETABLE|NEEDS_CPU_ACCESS|NEEDS_UC|INTERNAL_TEST|INTERNAL_64K|GGTT_INVALIDATE)/XE_BO_FLAG_\1/g'

And then the defines in drivers/gpu/drm/xe/xe_bo.h are adjusted to
follow the coding style.

a815362752 drm/i915: Try to relocate the BIOS fb to the start of ggtt
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

ea5e150ac2 drm/i915: Tweak BIOS fb reuse check
Currently we assume that we bind the BIOS fb exactly into the same
ggtt address where the BIOS left it. That is about to change, and
in order to keep intel_reuse_initial_plane_obj() working as intended
we need to compare the original ggtt offset (called 'base' here)
as opposed to the actual vma ggtt offset we selected. Otherwise
the first plane could change the ggtt offset, and then subsequent
planes would no longer notice that they are in fact using the same
ggtt offset that the first plane was already using. Thus the reuse
check will fail and we proceed to turn off these subsequent planes.

TODO: would probably make more sense to do the pure readout first
for all the planes, then check for fb reuse, and only then proceed
to pin the object into the final location in the ggtt...

The call to intel_power_domains_cleanup() needs to stay where it is for

As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there.

We do this by recompiling i915/display code twice.
Now that i915 has been adapted to support the Xe build, we can add
the xe/display support.

This initial work is a collaboration of many people and unfortunately
this squashed patch won't fully honor the proper credits.
But let's try to add a few from the squashed patches:
