Extend init/init_hw split to context init.
- Move context initialisation in to i915_gem_init_hw
- Move one off initialisation for render ring to
i915_gem_validate_context
- Move default context initialisation to logical_ring_init
Rename intel_lr_context_deferred_create to
intel_lr_context_deferred_alloc, to reflect reduced functionality &
alloc/init split.
This patch is intended to split out the allocation of resources &
initialisation to allow easier reuse of code for resume/gpu reset.
v2: Removed function ptr wrapping of do_switch_context (Daniel Vetter)
Left ->init_context int intel_lr_context_deferred_alloc
(Daniel Vetter)
Remove unnecessary init flag & ring type test. (Daniel Vetter)
Improve commit message (Daniel Vetter)
v3: On init/reinit, set the hw next sequence number to the sw next
sequence number. This is set to 1 at driver load time. This prevents
the seqno being reset on reinit (Chris Wilson)
v4: Set seqno back to ~0 - 0x1000 at start-of-day, and increment by 0x100
on reset.
This makes it obvious which bbs are which after a reset. (David Gordon
& John Harrison)
Rebase.
v5: Rebase. Fixed rebase breakage. Put context pinning in separate
function. Removed code churn. (Thomas Daniel)
v6: Cleanup up issues introduced in v2 & v5 (Thomas Daniel)
