> drm/i915/ringbuffer: Delay after invalidating gen6+ xcs
>
> During stress testing of full-ppgtt (on Baytrail at least), we found
> that the invalidation around a context/mm switch was insufficient (writes
> would go astray). Adding a second MI_FLUSH_DW barrier prevents this, but
> it is unclear as to whether this is merely a delaying tactic or if it is
> truly serialising with the TLB invalidation. Either way, it is
> empirically required.
