Here is an agenda for the XDP summit. We expect this to be a lot of
interactive conversation so the agenda can be dynamic as needed!

- page pool
Given I'll not participate physically, I'll give my page-pool status
here.

The page-pool idea was presented at MM-summit in April 2016:

Since I've written a more details design document (reviewed by Tom and
Alexei). I've not implemented any code for the page-pool yet. I've
read and discussed the current page-allocators per cpu caching of
order-0 pages with Mel Gorman. Mel is open to changes in this area.
We are looking at doing a "native" bulk between page-pool and
page-allocator, by aligning/sharing some of the same data-structures
(I see this as the page-pool "backend"). I want to prototype implement at
page-pool frontend, in-order to (1) benchmark if it is fast-enough
for perf-target, (2) to figure out the API drivers needs.
