CONFIG_PREEMPT_RT requires code to be as deterministic as possible,
and codes with interrupts disabled cannot use spinlocks.

In order to handle this correctly, we ensure any locking requirements
are handled before disabling interrupts, and only start locking again
after interrupts are re-enabled and timing sensitive path completed.

This also has the benefit of making the vblank evasion code more
deterministic; without locking there's much less jitter.

Previously, we scheduled vblank work on completion.
This is now handled by scheduling the vblank in advance, only arming
it upon completion without locks.

In case of vblank evasion in intel/display, it's necessary to
perform some work in advance, so the critical section will always run in
constant time on PREEMPT_RT.

By preparing all the work in advance, the part that needs to finish in
constant time only has to write a single variable instead. This allows
PREEMPT_RT to keep the interrupts disabled at the most critical part,
without completely reworking all locks to be raw spinlocks.

When trying to fix the hardware programming in intel/display, I had
to take all the vblank locks with local_irqs_disabled(). This
required converting the entire vblank code to raw spinlocks.

In the alternative approach, do all preparations in advance, and only
enable the vblank_event with interrupts disabled, this requires only
a simple write and prevents a complete re-architecture of the code.

This is converts the vblank functions to be called with interrupts
disabled, even on PREEMPT_RT kernels.

Because the PREEMPT_RT kernel converts all spinlocks to rt-mutexes,
the normal vblank functions cannot be used inside the critical section.

Instead, prepare the vblank at the start, and then enable the vblank
work after the hardware programming is completed.

This allows us to keep programming the hardware with interrupts
disabled, and still schedule completion on PREEMPT_RT on next vblank.

drm_crtc_vblank_put may take some locks, this should probably
not be the first thing we do after entering the time sensitive
part.

A better place is after programming is completed. Add a flag
to put the vblank after completion.

In the case of drm_vblank_work_schedule, we may not even need
to disable the vblank interrupt any more if it takes its own
reference.

finish_wait() may take a lock, which means that it can take any amount
of time. On PREEMPT-RT we should not be taking any lock after disabling
preemption, so ensure that the completion is done before disabling
interrupts.

This also has the benefit of making vblank evasion more deterministic,
by performing the final vblank check after all locking is done.

Now that we have a macro, might as well handle the VLV dsi workaround
too.

This makes the vblank evasion code slightly more deterministic, by not
looping with interrupts disabled.

From: Mike Galbraith <umgwanakikbuti@gmail.com>

Mario Kleiner suggest in commit
  ad3543ede630f ("drm/intel: Push get_scanout_position() timestamping into kms driver.")

a spots where preemption should be disabled on PREEMPT_RT. The
difference is that on PREEMPT_RT the intel_uncore::lock disables neither
preemption nor interrupts and so region remains preemptible.

The area covers only register reads and writes. The part that worries me
is:
- __intel_get_crtc_scanline() the worst case is 100us if no match is
  found.

- intel_crtc_scanlines_since_frame_timestamp() not sure how long this
  may take in the worst case.

It was in the RT queue for a while and nobody complained.
Disable preemption on PREEPMPT_RT during timestamping.

This splat will happen otherwise on all tracepoints too, for similar reasons.

Sashiko didn't complain about potential ivb/hsw same-cacheline issues
here, so I'll point it out. There isn't too much on that cacheline
though so perhaps not a huge issue (assuming the issue is real in the
first place, which I'm not 100% convinced about). But I'm still thinking
that I'll just try to convert the lock into a raw spinlock while moving
all the mmio stuff directly into intel_de.[ch]. That would avoid part
of the problem at least.

The dmc wakelock stuff I'm not sure we should even worry about here.
If the pipe isn't active we shouldn't really end up calling this anyway,
except maybe if we race with the DMC. Although we don't have register
accessors that skip the DMC stuff while still taking the uncore lock.
I'm not super keen on adding yet another register accessor variant
either, so not sure how to deal with this sort of stuff in the end...

This fixes a lockdep splat that occurs in the code that should be run
with interrupts disabled. The uncore and DMC locks should not be taken
and released repeatedly in a timing sensitive path.

This is the only user of intel_de_read64_2x32_volatile() and it
doesn't need any locking/wakelocks/etc so we should just convert
intel_de_read64_2x32_volatile() into intel_de_read64_2x32_volatile_fw().
And we should just skip the uncore dependency (so that we'll have one 
less thing to worry about later) so I'd just implement it directly in
intel_de.[ch] in terms of intel_de_read_fw().

commit b12b9e691fd6389de7294386dc81ad7f9fc984e8

    drm/i915/display: Do not take uncore lock in i915_get_vblank_counter
    
    This fixes a lockdep splat that occurs in the code that should be run
    with interrupts disabled. The uncore and DMC locks should not be taken
    and released repeatedly in a timing sensitive path.

Sashiko found a bunch of stuff that I was also thinking would be
a problem. Don't think I'll need to repeat it here.

I'm still thinking the easy way out would be to just convert
everything to raw spinlocks. The uncore lock I think should become
easier to deal with once I manage to move all of it into the
display code. I admit that the vblank locking is kinda annoying
and potentially inefficient. I've been pondering about making the
vblank locks to per-crtc to at least avoid some unnecessary contention,
but the fact that a lot of the drivers poke at the vblank internals
directly makes it a lot more work than it should be :/
