drm/i915/selftests: Pass intel_context to mock_request Modernise the mock_request factory to take intel_context not a (GEM context, intel_engine_cs) tuple.

drm/i915: Move i915_request_alloc into selftests/ 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.

drm/i915: Move GraphicsTechnology files under gt/ Start partitioning off the code that talks to the hardware (GT) from the uapi layers and move the device facing code under gt/ One casualty is s/intel_ringbuffer.h/intel_engine.h/ with the plan to subdivide that header and body further (and split out the submission code from the ringbuffer and logical context handling). This patch aims to be simple motion so git can fixup inflight patches with little mess.

drm/i915: Make request allocation caches global As kmem_caches share the same properties (size, allocation/free behaviour) for all potential devices, we can use global caches. While this potential has worse fragmentation behaviour (one can argue that different devices would have different activity lifetimes, but you can also argue that activity is temporal across the system) it is the default behaviour of the system at large to amalgamate matching caches. The benefit for us is much reduced pointer dancing along the frequent allocation paths. v2: Defer shrinking until after a global grace period for futureproofing multiple consumers of the slab caches, similar to the current strategy for avoiding shrinking too early.

drm/i915: Rename drm_i915_gem_request to i915_request We want to de-emphasize the link between the request (dependency, execution and fence tracking) from GEM and so rename the struct from drm_i915_gem_request to i915_request. That is we may implement the GEM user interface on top of requests, but they are an abstraction for tracking execution rather than an implementation detail of GEM. (Since they are not tied to HW, we keep the i915 prefix as opposed to intel.) In short, the spatch: @@ @@ - struct drm_i915_gem_request + struct i915_request A corollary to contracting the type name, we also harmonise on using 'rq' shorthand for local variables where space if of the essence and repetition makes 'request' unwieldy. For globals and struct members, 'request' is still much preferred for its clarity.
