Currently, we check we can send a pulse prior to disabling the
heartbeat to verify that we can change the heartbeat, but since we may
re-evaluate execution upon changing the heartbeat interval we need another
pulse afterwards to refresh execution.
v2: Tvrtko asked if we could reduce the double pulse to a single, which
opened up a discussion of how we should handle the pulse-error after
attempting to change the property, and the desire to serialise
adjustment of the property with its validating pulse, and unwind upon
failure.

We only allow persistent requests to remain on the GPU past the closure
of their containing context (and process) so long as they are continuously
checked for hangs or allow other requests to preempt them, as we need to
ensure forward progress of the system. If we allow persistent contexts
to remain on the system after the the hangcheck mechanism is disabled,
the system may grind to a halt. On disabling the mechanism, we sent a
pulse along the engine to remove all executing contexts from the engine
which would check for hung contexts -- but we did not prevent those
contexts from being resubmitted if they survived the final hangcheck.

Since the debugfs may peek into the GEM contexts as the corresponding
client/fd is being closed, we may try and follow a dangling pointer.
However, the context closure itself is serialised with the ctx->mutex,
so if we hold that mutex as we inspect the state coupled in the context,
we know the pointers within the context are stable and will remain valid
as we inspect their tables.

On 32b, highmem using a finite set of indirect PTE (i.e. vmap) to provide
virtual mappings of the high pages. As these are finite, map_new_virtual()
must wait for some other kmap() to finish when it runs out. If we map a
large number of objects, there is no method for it to tell us to release
the mappings, and we deadlock.
However, if we make an explicit vmap of the page, that uses a larger
vmalloc arena, and also has the ability to tell us to release unwanted
mappings. Most importantly, it will fail and propagate an error instead
of waiting forever.

Previously intel_dump_pipe_config() used to dump the full crtc state
whether or not the crtc was logically enabled or not. As that meant
occasionally dumping confusing stale garbage I changed it to
check whether the crtc is logically enabled or not. However I did
not realize that the state checker readout code does not
populate crtc_state.hw.{active,enabled}. Hence the state checker
dump would only give us a full dump of the sw state but not the hw
state. Fix that by populating those bits of the hw state as well.

The HVS FIFOs are currently assigned each time we have an atomic_check
for all the enabled CRTCs.
However, if we are running multiple outputs in parallel and we happen to
disable the first (by index) CRTC, we end up changing the assigned FIFO
of the second CRTC without disabling and reenabling the pixelvalve which
ends up in a stall and eventually a VBLANK timeout.
In order to fix this, we can create a special value for our assigned
channel to mark it as disabled, and if our CRTC already had an assigned
channel in its previous state, we keep on using it.

The current CRTC state reset hook in vc4 allocates a vc4_crtc_state
structure as a drm_crtc_state, and relies on the fact that vc4_crtc_state
embeds drm_crtc_state as its first member, and therefore can be safely
cast.
However, this is pretty fragile especially since there's no check for this
in place, and we're going to need to access vc4_crtc_state member at reset
so this looks like a good occasion to make it more robust.

In the case where we have a back-to-back submission that shares the same
BO, this BO will be prematurely moved to inactive_list while retiring the
first submit. But it will be still part of the second submit which is
being processed by the GPU. Now, if the shrinker happens to be triggered at
this point, it will result in a premature purging of this BO.
To fix this, we need to refcount BO while doing submit and retire. Then,
it should be moved to inactive list when this refcount becomes 0.

The reference to the VSP device acquired with of_find_device_by_node()
in rcar_du_vsp_init() is never released. Fix it with a drmm action,
which gets run both in the probe error path and in the remove path.

The DU driver handles non-visible planes (fully clipped by the display's
boundaries) by considering them as disabled. It thus disables the plane
at the hardware level when the plane is moved off-screen. However, if
the plane was previously disabled and is non-visible when it gets
enabled, the attempt to disable it crashes, as the plane wasn't
previously enabled. Fix it.

When creating a frame buffer, the driver verifies that the pitches for
the chroma planes match the luma plane. This is done incorrectly for
fully planar YUV formats, without taking horizontal subsampling into
account. Fix it.

The DT example erronously uses the "renesas,r8a7795-dw-hdmi", when the
correct value is "renesas,r8a7795-hdmi". It is furthermore missing the
generic "renesas,rcar-gen3-hdmi" compatible string. Fix it.
