There are a gazillion files that depend on drm_print.h being indirectly
included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In
preparation for removing those includes, explicitly include drm_print.h
where needed.

Split out display irq handling on ilk. Since the master IRQ enable is in
DEIIR, we'll need to do this in two parts. First, add
ilk_display_irq_master_disable() to disable master and south interrupts,
and second, add (repurposed) ilk_display_irq_handler() to finish display
irq handling.
It's not the prettiest thing you ever saw, but improves separation of
display irq handling. And removes HAS_PCH_NOP() and DISPLAY_VER() checks
from core irq code.
v2:
- Separate ilk_display_irq_master_enable() (Ville)
- Use _fw mmio accessors (Ville)

Figure out the enable mask for display things in display code. Reuse the
same function for both i915 and i965 code, the end result remains the
same.
This removes a pair of DISPLAY_VER() and HAS_HOTPLUG() checks from core

There are three groups of platforms using i915->irq_mask independently:
gen 2-4, VLV/CHV, and gen 5-7.
The gen 5-7 usage is primarily limited to display. Move its irq_mask
usage to struct intel_display as ilk_de_imr_mask for gen 5-7.
ilk_de_imr_mask could be put inside a union with with vlv_imr_mask and
de_irq_mask[], but keep them separate to avoid accidental aliasing of
the values.
With this, we can also drop the irq_mask member from struct xe_device.

This is a scripted split of the display related register macros from
i915_reg.h to display/intel_display_regs.h. As a starting point, move
all the macros that are only used in display code (or GVT). If there are
users in core i915 code or soc/, or no users anywhere, keep the macros
in i915_reg.h. This is done in groups of macros separated by blank
lines, moving the comments along with the groups.
Some manually picked macro groups are kept/moved regardless of the
heuristics above.
This is obviously a very crude approach. It's not perfect. But there are
4.2k lines in i915_reg.h, and its refactoring has ground to a halt. This
is the big hammer that splits the file to two, and enables further
cleanup.

Hook up PIPEDMC interrupts. We'll need these for:
- flip queue signalling
- GTT/ATS faults on LNL+
- unclaimed register access errors (supposedly that is what
the error interrupt indicated according to Windows code).
On LNL+ we get a new level of interrupts registers PIPEDMC_INTERRUPT*.
On earlier platforms we only have the INT_VECTOR field in the
PIPEDMC_STATUS registers, whose values are defined by the firmware.
For now we'll enable the interrupts on LNL+ only. For earlier platforms
it's not clear that there is any use for these interrupts, and some
ADL machines have exhibited spurious DE_PIPE interrupts with the
PIPEDMC interrupts unmasked/enabled. We can revisit enabling these
for earlier platforms in the future.
For some unknown reason LNL pipe B triggers the error interrupt
during the first DC state transition (subsequent transitions are
maybe OK?). No clear idea what's going on here yet, so keep the
error interrupt disabled for now.
Similar to DSB interrupt registers, the unused bits in
PIPEDMC_INTERRUPT* seem to act like randomg r/w bits (instead
of being hardwired to 0 like one would expect), and so we'll try
to avoid setting them so that we don't mistake them for real
interrupts.
v2: Only enable/unmask for LNL+
Keep the flip queue interrupt masked off for now since
we don't have a use for it yet

On LNL+ PIPEDMC faults are reported via PIPEDMC interrupts
instead of the direct DE_PIPE_* reporting used on earlier
platforms. Drop the relevant bits from the fault mask.
The bits are tied to zero on LNL, so there is no danger of
spurious fault interrupts even with an incorrect mask.

Observe that i915->irq_lock is no longer used to protect anything
outside of display. Make it a display thing.
This allows us to remove the ugly #define irq_lock irq.lock hack from xe
compat header.
Note that this is slightly more subtle than it first looks. For i915,
there's no functional change here. The lock is moved. However, for xe,
we'll now have *two* locks, xe->irq.lock and display->irq.lock. These
should protect different things, though. Indeed, nesting in the past
would've lead to a deadlock because they were the same lock.
With the i915 references gone, we can make a handful more files
independent of i915_drv.h.

Hook up the display fault irq handlers for VLV/CHV.
Unfortunately the actual hardware doesn't agree with the
spec on how DPINVGTT should behave. The docs claim that
the status bits can be cleared by writing '1' to them,
but in reality there doesn't seem to be any way to clear
them. So we must disable and ignore any fault we've already
seen in the past. The entire register does reset when
the display power well goes down, so we can just always
re-enable all the bits in irq postinstall without having
to track the state beyond that.

Decode the display faults a bit more extensively so that one
doesn't have to translate the bitmask to planes/etc. manually.
Also for plane faults we can read out a bit of state from the
relevant plane(s) and dump that out.

The if ladder in gen8_de_pipe_fault_mask() was missing one
else, add it. Doesn't actually matter since each if branch
just returns directly. But the code is less confusing when
you always do things the same way.

Going forward, struct intel_display is the main display device data
pointer. Convert i915_pipestat_enable_mask() to struct intel_display,
allowing further conversions elsewhere.

Pass intel_display to the display power stuff. These are spread
all over the place so tend to hinder clean conversions of whole
files.

The current display IRQ code calls some IRQ-specific helpers that use
intel_uncore_*() MMIO functions instead of the display-specific ones.
Wrap those helpers to ensure that the proper display-specific hooks
(currently only DMC wakelock handling) are called.
v2:
- Move functions to intel_display_irq.c instead of having them in
intel_de.h. (Jani)

Most of MMIO accesses from intel_display_irq.c are currently done via
uncore_*() functions instead of the display-specific ones, namely
intel_de_*(). Because of that, DMC wakelock ends up being ignored and
some invalid MMIO accesses are performed while display is in dynamic DC
states. Thus, update the display IRQ code to use the intel_de_*() MMIO
functions.
After this change, we are left with some IRQ-specific functions that
still use the unwrapped uncore_*() functions (i.e. gen2_irq_init,
gen3_irq_reset and gen2_assert_iir_is_zero). We will deal with them in
an upcoming change.

Going forward, struct intel_display is the main device data structure
for display. Convert the high level interfaces (init, cleanup, suspend,
resume, etc.) of intel_display_power.c over to it. The actual power
get/put etc. are left for follow-up.

vlv_display_irqs_enabled, to emphasize it's really only about VLV/CHV.

Move the check for display_irqs_enabled within vlv_display_irq_reset()
and vlv_display_irq_postinstall() to avoid looking at struct
intel_display members within i915 core irq code.
Within display irq code, vlv_display_irq_reset() may need to be called
with !display_irqs_enabled, so add a small wrapper.
