We can use the new pin/lazy unpin API for more performance
in the execlist submission paths.
The sticking point for me was the ringbuffer and Braswell having to
re-ioremap it every context pin. I hadn't noticed the kmap of the
context, but this does seem like a valid use for pin_map so I'm not
complaining... (Just saying this half the solution ;)
Pull in to the series "drm/i915: Move ioremap_wc tracking onto VMA" as
well then?
Oh, and you don't have pin_map for your ringbuffer either yet.
Confused, I did base this on top of "drm/i915: Refactor duplicate object
vmap functions" and the half missing is the ioremap paths. Which you
commented on above. What other ringbuffer is missing?
