Umesh Nerlige Ramappa authored
The oa object manages the oa buffer and must be allocated when the user intends to read performance counter snapshots. This can be achieved by making the oa object part of the stream object which is allocated when a stream is opened by the user. Attributes in the oa object that are gen-specific are moved to the perf object so that they can be initialized on driver load. The split provides a better separation of the objects used in perf implementation of i915 driver so that resources are allocated and initialized only when needed. v2: Fix checkpatch warnings v3: Addressed Lionel's review comment v4: Rebase v5: Fix rebase/merge issue with ratelimit_state_init Signed-off-by:

Use the same mechanism to determine if a backend engine exists for a uabi mapping as used internally. Signed-off-by:
-
Chris Wilson authored
During engine setup, we may find that some engines are fused off causing a misalignment between internal names and the instances seen by users, e.g. (I915_ENGINE_CLASS_VIDEO_DECODE, 1) may be vcs2 in hardware. Normally this is invisible to the user, but a few debug interfaces (and our own internal tracing) use the original HW name not the name the user would expect as formed from their class:instance tuple. Replace our internal name with the uabi name for consistency with, for example, error states. v2: Keep the pretty printing of class name in the selftest Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111311Signed-off-by:

We don't really want to use VM_IO for our GGTT mmaps (it implies that the mmap contains memory mapped registers, which we do not expose) yet I overzealously added it to an assert just because that's how we always had setup the vma. Signed-off-by:

Since commit 301efe96 ("drm/i915/uc: Don't fail on HuC firmware failure") we can continue driver load after error during HuC firmware load or authentication, but we could still fail on any error during early HuC initialization.

In the next patch, we would like to couple into the engine wakeref to free the batch pool on idling. The caveat here is that we therefore want to track the engine wakeref more precisely and to hold it instead of the broader GT wakeref as we process the ioctl. v2: Avoid introducing odd semantics for a shortlived timeline->mutex acquisition interface.

As we increase the number of RCU objects, it becomes easier for us to have several hundred thousand objects in the deferred RCU free queues. An example is gem_ctx_create/files which continually creates active contexts, which are not immediately freed upon close as they are kept alive by outstanding requests. This lack of backpressure allows the context objects to persist until they overwhelm and starve the system. We can increase our backpressure by flushing the freed object queue upon closing the device fd which should then not impact other clients. Testcase: igt/gem_ctx_create/*files Signed-off-by:

The shrinker cannot touch objects used by the contexts (logical state and ring). Currently we mark those as "pin_global" to let the shrinker skip over them, however, if we remove them from the shrinker lists entirely, we don't event have to include them in our shrink accounting. By keeping the unshrinkable objects in our shrinker tracking, we report a large number of objects available to be shrunk, and leave the shrinker deeply unsatisfied when we fail to reclaim those. The shrinker will persist in trying to reclaim the unavailable objects, forcing the system into a livelock (not even hitting the dread oomkiller). v2: Extend unshrinkable protection for perma-pinned scratch and guc allocations (Tvrtko) v3: Notice that we should be pinned when marking unshrinkable and so the link cannot be empty; merge duplicate paths.
