Currently we insert a arbitration point every 128MiB during a blitter copy. At 8GiB/s, this is around 30ms. This is a little on the large side if we need to inject a high priority work, so reduced it down to 8MiB or roughly 1ms. v2: Don't forget both fill/copy. Signed-off-by:

While processing CSB there is no need to look at GuC submission settings, just check if engine is configured for execlists mode. While today GuC submission is disabled it's settings are still based on modparam values that might not correctly reflect actual submission status in case of any fallback. Until that is fully fixed, use alternate method to confirm that engine really runs in execlists mode by comparing set_default_submission vfunc. v2: add other immediate use of new helper Signed-off-by:

The request's timeline will only contain requests from this context, in order of execution. Therefore, we can simply look back along this timeline to find the currently executing request. If we do find that the current context has completed its last request, that does not imply that all requests are completed in the context, so only advance the ring->head up to the end of the known completions!

We would like some freedom to break the user API/ABI for future HW but yet still expose the driver for upstream development on that HW. Currently, we have the i915.force_probe module parameter to avoid binding to HW while the driver is under development, but that is still a little too soft with respect to the stringent no-regression rules if we also plan to be redesigning the uAPI to go along with the new HW. To allow the uAPI to be changed during development, only expose that API and in development HW under STAGING (and BROKEN). Hopefully, making it explicit that such interfaces to that HW are under development and not to be blindly enabled by distributions. Signed-off-by:

i915_irq.c is large. One reason for this is that has a large chunk of the GT render power management stashed away in it. Extract that logic out of i915_irq.c and intel_pm.c and put it under one roof. Based on a patch by Chris Wilson. Signed-off-by:

As the GT may be running in parallel with the module initialisation code, we may enter i915_pmu_gt_parked() as we are executing i915_pmu_register(). We have to init the spinlock before we mark pmu.event_init so that it is available for use by i915_pmu_gt_parked() (which may run as soon as event_init is set).

We can be more aggressive in our testing by launching a number of kthreads, where each is submitting its own copy or fill batches on a set of random sized objects. Also since the underlying fill and copy batches can be pre-empted mid-batch(for particularly large objects), throw in a random mixture of ctx priorities per thread to make pre-emption a possibility.

Now that for all the relevant backends we do randomised testing, we need to make sure we still sanity check the obvious cases that might blow up, such that introducing a temporary regression is less likely. Also rather than do this for every backend, just limit to our two memory types: system and local. Suggested-by:

Ditch the dubious static list of sizes to enumerate, in favour of choosing a random size within the limits of each backing store. With repeated CI runs this should give us a wider range of object sizes, and in turn more page-size combinations, while using less machine time. Signed-off-by:

Split gen11_irq_handler() to receive as parameter the function pointers. This allows to share the interrupt handler even if the enable/disable functions are different. Make sure it's always inlined to avoid the extra indirect call on the hot path.
