Commit '3cf71bc9904d ("drm/i915: Re-apply "Perform link quality check,
unconditionally during long pulse"")' applies a work around for sinks
that don't signal link loss. The work around does not need to have to be
that broad as the issue was seen with only one particular monitor; limit
this only for external displays as eDP features like PSR turn off the link
and the driver ends up retraining the link seeeing that link is not
synchronized.

Comment claims link needs to be retrained because the connected sink raised
a long pulse to indicate link loss. If the sink did so,
intel_dp_hotplug() would have handled link retraining. Looking at the
logs in Bugzilla referenced in commit '3cf71bc9904d ("drm/i915: Re-apply
Perform link quality check, unconditionally during long pulse"")', the
issue is that the sink does not trigger an interrupt. What we want is
->detect() from user space to check link status and retrain. Ville's
review for the original patch also indicates the same root cause. So,
rewrite the comment.
v2: Patch split and rewrote comment.

If the request is currently on the HW (in port 0), then we do not need
to kick the submission tasklet to evaluate whether we should be
preempting itself in order to execute it again.
In the case that was annoying me:
execlists_schedule: rq(18:211173).prio=0 -> 2
need_preempt: last(18:211174).prio=0, queue.prio=2
We are bumping the priority of the first of a pair of requests running
in the current context. Then when evaluating preempt, we would see that
that our priority request is higher than the last executing request in
ELSP0 and so trigger preemption, not realising that our intended request
was already executing.
v2: As we assume state of the execlists->port[] that is only valid while
we hold the timeline lock we have to repeat some earlier tests that on
the validity of the node.
v3: Wrap guc submission under the timeline.lock as is now the way of all

Very light stress test to bombard the submission backends with a large
stream with requests of randomly assigned priorities. Preemption will be
occasionally requested, but unlikely to ever succeed! (Although we may
build a long queue of requests and so may trigger an attempt to inject a
preempt context, as we emit no batch, the arbitration window is limited
to between requests inside the ringbuffer. The likelihood of actually
causing a preemption event is therefore very small. A later variant
should try to improve the likelihood of preemption events!)

commit 4e0b83a567 ("drm/i915: Extract per-platform plane->check()

I was going to add it back when introducing GTT remapping for the

it separately.
So let's add the max stride check back. And let's do it in a nicer
form than what we had before and do it for all plane types (easy
now that we have the ->max_stride() plane vfunc).
Only sprite planes really need this for now since primary planes
are capable of scanning out the current max fb size we allow, and
cursors have more stringent stride checks elsewhere.

meaning. Don't set it, and make clear the distinction between
SKL and later PS values.
Changes since v1:
- Add missing break statement.

drm_atomic_helper_commit_planes_on_crtc calls begin_commit,
then plane_update hooks, then flush_commit. Because we keep our own
visibility tracking through plane_state->visible there's no need to
rely on the atomic hooks for this.
By explicitly writing our own helper, we can update visible planes
as needed, which is useful to make NV12 support work as intended.
Changes since v1:
- Reword commit message. (Matt Roper)
- Rename to intel_update_planes_on_crtc(). (Matt)

This will only disable planes we actually had marked as visible in
crtc_state->visible_planes and cleans up intel_crtc_disable_plane()
slightly.
This is also useful for when we start enabling NV12 support for gen11,
in which we will make the separate Y plane visible, but ignore the
Y plane's state.

We need to assume the plane has been visible before, even if no CRTC
is assigned to the plane. This is because when enabling a nv12 plane
on gen11, we will have to enable an extra plane and make it visible
by marking it in crtc_state->active_planes for
intel_update_planes_on_crtc().
Additionally, clear visible flag in intel_plane_atomic_check, in case
we ever hit a bug with visibility. Our code implicitly assumes that
plane_state->visible is only true when crtc and fb are set,
so we will either null deref in intel_fbc_choose_crtc() or
do something bad during the actual commit which cares even more.
Changes since v1:
- Unconditionally clear crtc_state->active_planes as well.
- Reword commit message, since this is now a preparation patch for
NV12 Y / UV plane linking.

While we may not update new_crtc_state, we may clear active_planes
if the new cursor update state will disable the cursor, but we fail
after. If this is immediately followed by a modeset disable, we may
soon not disable the planes correctly when we start depending on
active_planes.
Changes since v1:
- Clarify why we cannot swap crtc_state. (Matt)

Fix up the error unwind for logical_ring_init() failing by moving the
cleanup into the callers who own the various bits of state during
initialisation, so we don't forget to free the state allocated by the
caller.

Once we have flushed the first request through the system to both load a
context and record the default state; tell the GPU to park and idle
itself, putting itself immediately (hopefully at least) into a
powersaving state, and allowing ourselves to start from known state
after setting up all our bookkeeping.
