We can forgo an evict-everything here as the shrinker operation itself will unbind any vma as required. If we explicitly idle the GPU through a switch to the default context, we not only create a request in an illegal context (e.g. whilst shrinking during execbuf with a request already allocated), but switching to the default context will not free up the memory backing the active contexts - unless in the unlikely situation that context had already been closed (and just kept arrive by being the current context). The saving is near zero and the danger real. To compensate for the loss of the forced retire, add a couple of retire-requests to i915_gem_shirnk() - this should help free up any transitive cache from the requests. Note that the second retire_requests is for the benefit of the hand-rolled execlist ctx active tracking: We need to manually kick requests to get those unpinned again. Once that's fixed we can try to remove this again.
