An interesting observation made with our parallel selftests was that on our small/single cpu systems we would call kthread_stop() before the kthreads were spawned. If this happens, the kthread is never run at all; completely bypassing the test. A simple yield() from the parent will ensure that all children have the opportunity to start before we reap them.

Don't just look at the very last request in a queue when deciding if we need to evict the context from the GPU, as that request may still be in the submission queue while the rest of the context is running!

Intended for upstream testing so that we can still exercise the LMEM plumbing and !i915_ggtt_has_aperture paths. Smoke tested on Skull Canyon device. This works by allocating an intel_memory_region for a reserved portion of system memory, which we treat like LMEM. For the LMEMBAR we steal the aperture and 1:1 it map to the stolen region. To enable simply set the i915 modparam fake_lmem_start= on the kernel cmdline with the start of reserved region(see memmap=). The size of the region we can use is determined by the size of the mappable aperture, so the size of reserved region should be >= mappable_end. For now we only enable for the selftests. Depends on CONFIG_DRM_I915_UNSTABLE being enabled. eg. memmap=2G$16G i915.fake_lmem_start=0x400000000 v2: make fake_lmem_start an i915 modparam Signed-off-by:

In order to keep the assert_bind_count() valid, we need to hold the vma page reference until after we drop the bind count. However, we must also keep the drm_mm_remove_node() as the last action of i915_vma_unbind() so that it serialises with the unlocked check inside i915_vma_destroy(). So we need to split up i915_vma_remove() so that we order the detach, drop pages and remove as required during unbind. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=112067Signed-off-by:

For the HPD interrupt functionality the HW depends on power wells in the display core domain to be on. Accordingly when enabling these power wells the HPD polling logic will force an HPD detection cycle to account for hotplug events that may have happened when such a power well was off. Thus a detect cycle started by polling could start a new detect cycle if a power well in the display core domain gets enabled during detect and stays enabled after detect completes. That in turn can lead to a detection cycle runaway. To prevent re-triggering a poll-detect cycle make sure we drop all power references we acquired during detect synchronously by the end of detect. This will let the poll-detect logic continue with polling (matching the off state of the corresponding power wells) instead of scheduling a new detection cycle.

Our existing behaviour is to allow contexts and their GPU requests to persist past the point of closure until the requests are complete. This allows clients to operate in a 'fire-and-forget' manner where they can setup a rendering pipeline and hand it over to the display server and immediately exit. As the rendering pipeline is kept alive until completion, the display server (or other consumer) can use the results in the future and present them to the user. The compute model is a little different. They have little to no buffer sharing between processes as their kernels tend to operate on a continuous stream, feeding the results back to the client application. These kernels operate for an indeterminate length of time, with many clients wishing that the kernel was always running for as long as they keep feeding in the data, i.e. acting like a DSP. Not all clients want this persistent "desktop" behaviour and would prefer that the contexts are cleaned up immediately upon closure. This ensures that when clients are run without hangchecking (e.g. for compute kernels of indeterminate runtime), any GPU hang or other unexpected workloads are terminated with the process and does not continue to hog resources. The default behaviour for new contexts is the legacy persistence mode, as some desktop applications are dependent upon the existing behaviour. New clients will have to opt in to immediate cleanup on context closure. If the hangchecking modparam is disabled, so is persistent context support -- all contexts will be terminated on closure. We expect this behaviour change to be welcomed by compute users, who have often been caught between a rock and a hard place. They disable hangchecking to avoid their kernels being "unfairly" declared hung, but have also experienced true hangs that the system was then unable to clean up. Naturally, this leads to bug reports. Testcase: igt/gem_ctx_persistence Link: https://github.com/intel/compute-runtime/pull/228Signed-off-by:

Execlists uses a scheduling quantum (a timeslice) to alternate execution between ready-to-run contexts of equal priority. This ensures that all users (though only if they of equal importance) have the opportunity to run and prevents livelocks where contexts may have implicit ordering due to userspace semaphores. However, not all workloads necessarily benefit from timeslicing and in the extreme some sysadmin may want to disable or reduce the timeslicing granularity.

The design of the OA unit has been split into several units. We now have a global unit (OAG) and a render specific unit (OAR). This leads to some changes on how we program things. Some details : OAR: - has its own set of counter registers, they are per-context saved/restored - counters are not written to the circular OA buffer - a snapshot of the counters can be acquired with MI_RECORD_PERF_COUNT, or a single counter can be read with MI_STORE_REGISTER_MEM. OAG: - has global counters that increment across context switches - counters are written into the circular OA buffer (if requested) v2: Fix checkpatch warnings on code style (Lucas) v3: (Umesh) - Update register from which tail, status and head are read - Update logic to sample context reports - Update whitelist mux and b counter regs v4: Fix a bug when updating context image for new contexts (Umesh) v5: Squash patch enabling save/restore of counters into context image We want this so we can preempt performance queries and keep the system responsive even when long running queries are ongoing.
