The workqueue code complains viciously if we try to queue more work onto the queue while attampting to drain it. As we asynchronously free objects and defer their enqueuing with RCU, it is quite tricky to quiesce the system before attempting to drain the workqueue. Yet drain we must to ensure that the worker is idle before unloading the module. Give the freed object drain 3 whole passes with multiple rcu_barrier() to give the defer freeing of several levels each protected by RCU and needing a grace period before its parent can be freed, ultimately resulting in a GEM object being freed after another RCU period. A consequence is that it will make module unload even slower. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110550Signed-off-by:

Make the engine responsible for cleaning itself up! This removes the i915->gt.cleanup vfunc that has been annoying the casual reader and myself for the last several years, and helps keep a future patch to add more cleanup tidy. v2: Assert that engine->destroy is set after the backend starts allocating its own state.

The pipe has a special HDR mode with higher precision when only HDR planes are active. Let's use it. Curiously this fixes the kms_color gamma/degamma tests when using a HDR plane, which is always the case unless one hacks the test to use an SDR plane. If one does hack the test to use an SDR plane it does pass already. I have no actual explanation how the output after the gamma LUT can be different between the two modes. The way the tests are written should mean that the output should be identical between the solid color vs. the gradient. But clearly that somehow doesn't hold true for the HDR planes in non-HDR pipe mode. Anyways, as long as we stick to one type of plane the test should produce sensible results now. v2: s/HDR_MODE/HDR_MODE_PRECISION/ (Shashank) Signed-off-by:

It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes. Reviewed-by:

Having transitioned GEM over to using intel_context as its primary means of tracking the GEM context and engine combined and using i915_request_create(), we can move the older i915_request_alloc() helper function into selftests/ where the remaining users are confined. Signed-off-by:

We switched to a tree of per-engine HW context to accommodate the introduction of virtual engines. However, we plan to also support multiple instances of the same engine within the GEM context, defeating our use of the engine as a key to looking up the HW context. Just allocate a logical per-engine instance and always use an index into the ctx->engines[]. Later on, this ctx->engines[] may be replaced by a user specified map. v2: Add for_each_gem_engine() helper to iterator within the engines lock v3: intel_context_create_request() helper v4: s/unsigned long/unsigned int/ 4 billion engines is quite enough. v5: Push iterator locking to caller Signed-off-by:

We want to pass in a intel_context into intel_context_pin() and that requires us to first be able to lookup the intel_context! Signed-off-by:

Chris Wilson authored
Our eventual goal is to rid request construction of struct_mutex, with the short term step of lifting the struct_mutex requirements into the higher levels (i.e. the caller must ensure that the context is already pinned into the GTT). In this patch, we pin GVT's shadow context upon allocation and so keep them pinned into the GGTT for as long as the virtual machine is alive, and so we can use the simpler request construction path safe in the knowledge that the hard work is already done.
