Allow super long OpenCL workloads which cannot be preempted within
the default timeout to run out of the box.
v2:
* Make it stick out more and apply only to RCS. (Chris)
v3:
* Mention platform override in kconfig. (Joonas)

When applying the context-barrier, we only care about the current
engines, as the next set of engines will be naturally after the barrier.
So we can skip holding the ctx->engines_mutex while constructing the
request by taking a sneaky reference to the i915_gem_engines instead.

The sw-fence notify function requires to be at least 4-byte aligned so
that we can use the low bits in the function pointer for internal fence
flags. Make it so.

Since the semaphore fence may be signaled from inside an interrupt
handler from inside a request holding its request->lock, we cannot then
enter into the engine->active.lock for processing the semaphore priority
bump as we may traverse our call tree and end up on another held
request.

If we stop filling the ELSP due to an incompatible virtual engine
request, check if we should enable the timeslice on behalf of the queue.
This fixes the case where we are inspecting the last->next element when
we know that the last element is the last request in the execution queue,
and so decided we did not need to enable timeslicing despite the intent
to do so!

Commit c3b5a8430daad ("drm/i915/gvt: Enable gfx virtualiztion for CFL")
added the support on CFL. The vgpu emulation hotplug support on CFL was
supposed to be included in that patch. Without the vgpu emulation
hotplug support, the dma-buf based display gives us a blur face.
So fix this issue by adding the vgpu emulation hotplug support on CFL.

Requests within a timeline are ordered by that timeline, so awaiting for
the start of a request within the timeline is a no-op. This used to work
by falling out of the mutex_trylock() as the signaler and waiter had the

drm_dp_mst_topology_mgr_cbs.destroy_connector callbacks are identical
amongst every driver and don't do anything other than cleaning up the
connector((drm_connector_unregister()/drm_connector_put())) except for
amdgpu_dm driver where some amdgpu_dm specific code in there.
This connector cleaning up is now being handled in the drm core so
driver destroy_connector callbacks are not needed (except for
amdgpu_dm) hence remove them.
Removal is done with below sementic patch:
@r1@
identifier func, E;
@@
struct drm_dp_mst_topology_cbs E = {
...,
- .destroy_connector = func
};
@delete depends on r1@

Convert various uses of the printk based drm logging macros to the

i915/display/intel_lpe_audio.c.
Note that this converts DRM_DEBUG to drm_dbg().

Converts various instances of the printk based drm logging macros to the
struct drm_device based logging macros in i915/display/intel_hotplug.c.
In some cases, this involves extracting the drm_i915_private pointer from
the drm_device struct to be used in the logging macros.

the intel_context.inflight is updated atomically, and so we must
annotate the racy read from outside the owning context.

Since the semaphore fence may be signaled from inside an interrupt
handler from inside a request holding its request->lock, we cannot then
enter into the engine->active.lock for processing the semaphore priority
bump as we may traverse our call tree and end up on another held
request.

Most of the kms_frontbuffer_tracking tests disables the feature being
tested, draw, get the CRC then enable the feature, draw again, get the
CRC and check if it matches.
Some times it is able to do that with a fastset, so
intel_pre_plane_update() is executed but intel_fbc_can_flip_nuke() was
not checking if FBC is now enabled in this CRTC leaving FBC active and
causing the warning bellow in __intel_fbc_disable()

drm_dp_mst_connector_early_unregister(),

Always wait on the start of the signaler request to reduce the problem
of dequeueing the bonded pair too early -- we want both payloads to
start at the same time, with no latency, and yet still allow others to
make full use of the slack in the system. This reduce the amount of time
we spend waiting on the semaphore used to synchronise the start of the
bonded payload.

gmbus/aux may be clocked by cdclk, thus we should make sure no
transfers are ongoing while the cdclk frequency is being changed.
We do that by simply grabbing all the gmbus/aux mutexes. No one
else should be holding any more than one of those at a time so
the lock ordering here shouldn't matter.

The low level read_lut() functions don't need the entire crtc state
as they know exactly what they're reading. Just need to pass in the
crtc to get at the pipe. This now neatly mirrors the load_lut()
direction.

PIPEGCMAX is a 11.6 (or 1.16 if you will) value. Ie. it can
represent a value of 1.0 when the maximum we can store in the
software LUT is 0.ffff. Clamp the value so that it gets
saturated to the max the uapi supports.

A variable called 'i' having an unsigned type is just looking for
trouble, and using a sized type generally makes no sense either.
Change all of them to just plain old int. And do the same for some
'lut_size' variables which generally provide the loop end codition
for 'i'.

Only load the CGM CSC based on the cgm_mode bit like we
do with the gamma/degamma LUTs. And make the function
naming and arguments consistent as well.
TODO: the code to convert the coefficients look totally
bogus. IIRC CHV uses two's complement format but the code
certainly doesn't generate that, so probably negative
coefficients are totally busted.
