	)

i915_switch_context() - perform a GPU context switch. : ring for which we'll execute the context switch : file_priv associated with the context, may be NULL : context id number : sequence number by which the new context will be switched to :

The context life cycle is simple. The context refcount is incremented and decremented by 1 and create and destroy. If the context is in use by the GPU, it will have a refoucnt > 1. This allows us to destroy the context abstract object while letting the normal object tracking destroy the backing BO.
