drm/i915: Move linetime wms into the crtc state
The linetime watermarks really have very little in common with the
plane watermarks. It looks to be cleaner to simply track them in
the crtc_state and program them from the normal modeset/fastset
paths.
The only dark cloud comes from the fact that the register is
still supposedly single buffered. So in theory it might still
need some form of two stage programming. Note that even though
HSW/BDWhave two stage programming we never computed any special
intermediate values for the linetime watermarks, and on SKL+
we don't even have the two stage stuff plugged in since everything
else is double buffered. So let's assume it's all fine and
continue doing what we've been doing.
Actually on HSW/BDW the value should not even change without
a full modeset since it doesn't account for pfit downscaling.
Thus only fastboot might be affected. But on SKL+ the pfit
scaling factor is take into consideration so the value may
change during any fastset.
As a bonus we'll plug this thing into the state
checker/dump now.
v2: Rebase due to bigjoiner prep
v2: Only compute ips linetime for IPS capable pipes.
Bspec says the register values is ignored for other
pipes, but in fact it can't even be written so the
state checker becomes unhappy if we don't compute
it as zero.

On Braswell and Broxton (also known as Valleyview and Apollolake), we
need to serialise updates of the GGTT using the big stop_machine()

reclaim (since it uses the cpuhp mutex and that is tainted by per-cpu

drm/i915: Tighten atomicity of i915_active_acquire vs i915_active_release
As we use a mutex to serialise the first acquire (as it may be a lengthy
operation), but only an atomic decrement for the release, we have to
be careful in case a second thread races and completes both
acquire/release as the first finishes its acquire.
Thread A Thread B
i915_active_acquire i915_active_acquire
atomic_read() == 0 atomic_read() == 0
mutex_lock() mutex_lock()
atomic_read() == 0
ref->active();
atomic_inc()
mutex_unlock()
atomic_read() == 1
i915_active_release
atomic_dec_and_test() -> 0
ref->retire()
atomic_inc() -> 1
mutex_unlock()
So thread A has acquired the ref->active_count but since the ref was
still active at the time, it did not initialise it. By switching the
check inside the mutex to an atomic increment only if already active, we
close the race.

drm/i915/lvds: use intel_de_*() functions for register access
The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().
Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().
No functional changes.

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().
Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),

drm/i915: Fix modeset locks in sanitize_watermarks()
We've added more internal things that use modeset locks and
thus we need to be prepared for intel_atomic_check() grabbing
more locks than what our initial drm_modeset_lock_all_ctx()
took. So we're missing the backoff handling here.
Also drm_atomic_helper_duplicate_state() works against us
by clearing state->acquire_ctx in anticipation of
drm_atomic_helper_commit_duplicated_state() being used to
commit the state.
We could probably just reset acquire_ctx back, but instead
let's just rewrite the whole thing without using either of
those "helpers". There's also no need to add any connectors
to the state here since we just want the new watermarks
which don't depend on connectors.

drm/i915: Fix inconsistance between pfit.enable and scaler freeing
Despite that during hw readout we seem to have scalers assigned
to pipes, then call atomic_setup_scalers, at the commit stage in
skl_update_scaler there is a check, that if we have fb src and
dest of same size, we stage freeing of that scaler.
However we don't update pfit.enabled flag then, which makes
the state inconsistent, which in turn triggers a WARN_ON
in skl_pfit_enable, because we have pfit enabled,
but no assigned scaler.
To me this looks weird that we kind of do the decision
to use or not use the scaler at skl_update_scaler stage
but not in intel_atomic_setup_scalers, moreover
not updating the whole state consistently.
This fix is to not free the scaler if we have pfit.enabled
flag set, so that the state is now consistent
and the warnings are gone.
v2: - Put pfit.enable check into crtc specific place

drm/i915: Remove 'prefault_disable' modparam
The 'prefault_disable' modparam was used by IGT to prevent a few
prefaulting operations to make fault handling under struct_mutex more
prominent. With the removal of struct_mutex, this is not as important
any more and we have almost completely stopped using the parameter. The
remaining use in execbuf is now immaterial and can be dropped without
affecting coverage.
We must re-address the idea of fault injection though.

drm/i915/guc: Don't GEM_BUG_ON on corrupted H2G CTB
We should never BUG_ON on any corruption in CTB descriptor as
data there can be also modified by the GuC. Instead we can
use flag "is_in_error" to indicate that we will not process
any further messages over this CTB (until reset).

drm/i915/tgl: Re-enable RPS
We disabled rps while it appeared to be a contributing factor to system
instablity, as that is now resolved, re-enable RPS and see how we fare.

drm/i915/gt: Poison GTT scratch pages
Using a clear page for scratch means that we have relatively benign
errors in case it is accidentally used, but that can be rather too
benign for debugging. If we poison the scratch, ideally it quickly
results in an obvious error.
v2: Set each page individually just in case we are using highmem for our
scratch page.
v3: Pick a new scratch register as MI_STORE_REGISTER_MEM does not work
with GPR0 on gen7, unbelievably.
v4: Haswell still considers 3DPRIM a privileged register!

drm/i915/gt: Flush engine parking before release
Due to the asynchronous nature of releasing our wakerefs, we can signal
the main GT wakeref as complete before the individual engines have
cleared their own wakerefs. During shutdown we assert that the engines
are indeed parked before we release them, but for this to be always true
we need to flush their workers as well.

drm/i915/ehl: Ensure that the DDI selection MUX is programmed correctly
Perhaps in some cases the BIOS/GOP or other firmware may turn on
PHY A but may not program the MUX correctly. Therefore, re-program
PHY A if it is determined after reading the VBT that the value
programmed for the MUX bit does not match the expected value.
