Since the reset path wants to recover the engines itself, it only wants to reinitialise the hardware using i915_gem_init_hw(). Pull the call to intel_engines_resume() to the module init/resume path so we can avoid it during reset. Fixes: 79ffac85 ("drm/i915: Invert the GEM wakeref hierarchy") Signed-off-by:

If we issue a reset to a currently idle engine, leave it idle afterwards. This is useful to excise a linkage between reset and the shrinker. When waking the engine, we need to pin the default context image which we use for overwriting a guilty context -- if the engine is idle we do not need this pinned image! However, this pinning means that waking the engine acquires the FS_RECLAIM, and so may trigger the shrinker. The shrinker itself may need to wait upon the GPU to unbind and object and so may require services of reset; ergo we should avoid the engine wake up path. The danger in skipping the recovery for idle engines is that we leave the engine with no context defined, which may interfere with the operation of the power context on some older platforms. In practice, we should only be resetting an active GPU but it something to look out for on Ironlake (if memory serves). Fixes: 79ffac85 ("drm/i915: Invert the GEM wakeref hierarchy") Signed-off-by:

For use in the next patch, we want to acquire a wakeref without having to wake the device up -- i.e. only acquire the engine wakeref if the engine is already active. Signed-off-by:

Stop using the irq vfuncs under drm_driver.

Gen2 doesn't have a frame counter and apparently we no longer provide a fake .get_vblank_counter() hook for it. That means all tracepoints calling that hook will oops. Update the tracepoints to use intel_crtc_get_vblank_counter() which will gracefully fall back to using the software counter. This is actually a better approach since we now get (hopefully accurate) frame numbers in the traces. This also gets rid of the raw driver->get_vblank_counter() calls, which we need to do in order to switch to the per-crtc vblank vfuncs. v2: Deal with new tracepoints v3: Use a distinct variable name for the internal crtc iterator (Chris) Cc: Shawn Guo <shawn.guo@linaro.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Fixes: 967dd484 ("drm: remove drm_vblank_no_hw_counter assignment from driver code") Signed-off-by:

In order for the reset count to be accurate across our selftest, we need to prevent the background retire worker from modifying our expected state. To preserve the intent of symmetry, we apply this to both i915_reset and i915_reset_engine, even though it strictly only affects i915_reset_engine currently. Signed-off-by:

We no longer allocate a contiguous set of timeline ids for all engines upon creation, so we no longer should assume that the timelines are densely allocated within a context. Hopefully, the set of fences used within a workload are still dense enough for us to take advantage of the compressed radix tree used for the syncmap. Signed-off-by:

The Demand Prefetch workaround (binding table prefetching) only applies to Icelake A0/B0. But the Sampler Prefetch workaround needs to be applied to all Gen11 steppings, according to a programming note in the SARCHKMD documentation. Using the Intel Gallium driver, I have seen intermittent failures in the dEQP-GLES31.functional.copy_image.non_compressed.* tests. After applying this workaround, the tests reliably pass. v2: Remove the overlap with a pre-production w/a BSpec: 9663 Signed-off-by:

In the unlikely case (thank you CI!), we may find ourselves wanting to issue a preemption but having no runnable requests left. In this case, we set the semaphore before computing the preemption and so must unset it before forgetting (or else we leave the machine busywaiting until the next request comes along and so likely hang). v2: Replace readback with only a wmb after asserting the semaphore Signed-off-by:

As we have already plugged the w->dma into the reservation_object, and have set ourselves up to automatically signal the request and w->dma on completion, we do not need to export the rq->fence directly and just use the w->dma fence. This avoids having to take the reservation_lock inside the worker which cross-release lockdep would complain about. :) Signed-off-by:

If we introduce a callback for i915_active that is only called the first time we use the i915_active and is symmetrically paired with the i915_active.retire callback, we can replace the open-coded and non-atomic implementations -- which will be very fragile (i.e. broken) upon removing the struct_mutex serialisation.

Remove the accumulated optimisations that we have for i915_vma_retire and reduce it to the bare essential of tracking the active object reference. This allows us to only use atomic operations, and so will be able to avoid the struct_mutex requirement. The principal loss here is the shrinker MRU bumping, so now if we have to shrink, we will do so in much more random order and more likely to try and shrink recently used objects. That is a nuisance, but shrinking active objects is a second step we try to avoid and will always be a system-wide performance issue. The other loss is here is in the automatic pruning of the reservation_object when idling. This is not as large an issue as upon reservation_object introduction as now adding new fences into the object replaces already signaled fences, keeping the array compact. But we do lose the auto-expiration of stale fences and unused arrays. That may be a noticeable problem for which we need to re-implement autopruning. Signed-off-by:

Provide runtime asserts and tracking of i915_active via debugobjects. For example, this should allow us to check that the i915_active is only active when we expect it to be and is never freed too early. One consequence is that, for simplicity, we no longer allow i915_active to be on-stack which only affected the selftests. Signed-off-by:

i915_gem_wait_for_idle() and i915_retire_requests() introduce a dependency on the timeline->mutex. This is problematic as we want to later perform allocations underneath i915_active.mutex, forming a link between the shrinker, the timeline and active mutexes. Nip this cycle in the bud by removing the acquisition of the timeline mutex (i.e. retiring) from inside the shrinker. Signed-off-by:

There is a very small chance of triggering a log flush event when enabling or disabling CT buffers. Events triggered while CT buffers are disabled are logged in the SCRATCH_15 register using the same bits used in the CT message payload. Since our communication channel with GuC is turned off, we can save the message and handle it after we turn it back on. GuC should be idle and not generate more events in the meantime because we're not talking to it. v2: clear the mmio register on stop_communication as well (Chris) Signed-off-by:

Make sure we always have CT buffers enabled when the interrupts are enabled, so we can always handle interrupts from GuC. Also move the setting of the guc->send and guc->handler functions to the GuC communication control functions for consistency. The reorder also fixes the onion unwinding of intel_uc_init_hw, because guc_enable_communication would've left interrupts enabled when failing to enable CTB. v2: always retunr the result of ctch_enable() in intel_guc_ct_enable() (Michal) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110943Signed-off-by:Matthew Brost <matthew.brost@intel.com> Reviewed-by:
