[PATCH for-next v3 0/2] RDMA/rxe: Prefetching pages with explicit ODP

Posted by Daisuke Matsuda 9 months ago

There is ibv_advise_mr(3) that can be used by applications to optimize
memory access. This series enables the feature on rxe driver, which has
already been available in mlx5.

There is a tiny change on the rdma-core util.
cf. https://github.com/linux-rdma/rdma-core/pull/1605
