Taken from an idea used for FQ_CODEL, we give the first request of a new request flows a small priority boost. These flows are likely to correspond with short, interactive tasks and so be more latency sensitive than the longer free running queues. As soon as the client has more than one request in the queue, further requests are not boosted and it settles down into ordinary steady state behaviour. Such small kicks dramatically help combat the starvation issue, by allowing each client the opportunity to run even when the system is under heavy throughput load (within the constraints of the user selected priority). v2: Mark the preempted request as the start of a new flow, to prevent a single client being continually gazumped by its peers.

As we are about to allow ourselves to slightly bump the user priority into a few different sublevels, packthose internal priority lists into the same i915_priolist to keep the rbtree compact and avoid having to allocate the default user priority even after the internal bumping. The downside to having an requests[] rather than a node per active list, is that we then have to walk over the empty higher priority lists. To compensate, we track the active buckets and use a small bitmap to skip over any inactive ones. v2: Use MASK of internal levels to simplify our usage. v3: Prevent overflow when SHIFT is zero.

We've opted to use the maximum link rate and lane count for eDP panels, because typically the maximum supported configuration reported by the panel has matched the native resolution requirements of the panel, and optimizing the link has lead to problems. With eDP 1.4 rate select method and DSC features, this is decreasingly the case. There's a need to optimize the link parameters. Moreover, already eDP 1.3 states fast link with fewer lanes is preferred over the wide and slow. (Wide and slow should still be more reliable for longer cable lengths.) Additionally, there have been reports of panels failing on arbitrary link configurations, although arguably all configurations they claim to support should work. Optimize eDP 1.4+ link config fast and narrow. Side note: The implementation has a near duplicate of the link config function, with just the two inner for loops turned inside out. Perhaps there'd be a way to make this, say, more table driven to reduce the duplication, but seems like that would lead to duplication in the table generation. We'll also have to see how the link config optimization for DSC turns out.

Commit '3cf71bc9 ("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 '3cf71bc9 ("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 things.

The new GPD win2 device uses a portrait screen in a landscape case, so now we've a device with an eDP panel which needs the panel-orientation property to let the fbcon code and userspace know that the image needs to be fixed-up.

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!) v2: Include a second pattern with more frequent preemption Signed-off-by:

commit 4e0b83a5 ("drm/i915: Extract per-platform plane->check() functions") removed the plane max stride check for sprite planes. I was going to add it back when introducing GTT remapping for the display, but after further thought it seems better to re-introduce 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.

Our execlist dispatch code requires a ppGTT so make sure we enforce that option in intel_sanitize_enable_ppgtt(). The comment already tries to explain that execlists requires ppgtt, but was written when gen8 may have also taken the legacy path; so rewrite the code to match the comment by using HAS_EXECLISTS() feature instead of the gen.
