[Intel-gfx] [PATCH 08/50] drm/i915: Pass intel_context to i915_request_create()
Chris Wilson
chris at chris-wilson.co.uk
Fri Apr 12 08:53:28 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.
For the purpose of emitting a request from inside retirement (see the
next patch for engine power management), we also need to lift control
over the timeline mutex to the caller.
v2: Note that the request carries the active reference upon construction.
