[Intel-gfx] [PATCH 06/22] drm/i915: Pass intel_context to i915_request_create()
Chris Wilson
chris at chris-wilson.co.uk
Mon Mar 25 09:03:57 UTC 2019
Start acquiring the logical intel_context and using that as our primary
means for request allocation. This is the initial step to allow us to
avoid requiring struct_mutex for request allocation along the
perma-pinned kernel context, but it also provides a foundation for
breaking up the complex request allocation to handle different scenarios
inside execbuf.
