In pwrite_fast, map an object page by page if obj_ggtt_pin fails. First,
we try a nonblocking pin for the whole object (since that is fastest if
reused), then failing that we try to grab one page in the mappable
aperture. It also allows us to handle objects larger than the mappable
aperture (e.g. if we need to pwrite with vGPU restricting the aperture
to a measely 8MiB or something like that).
Aperture in aperture, reminds me of those "Yo dawg I've heard you like X
so I've put X in your X so you can Y while you Y" jokes. :D
Would using the partial view code be interesting for this? Might be
faster due to larger chunks possible, or slower due more expensive set
up time, I don't know.
Interesting thing is it was added for virtualization use cases so there
is overlap here.
