Subject: [PATCH for-next v3 0/2] RDMA/rxe: Prefetching pages with explicit ODP
Date: Tue, 13 May 2025 05:04:03 +0000 [thread overview]
Message-ID: <20250513050405.3456-1-dskmtsd@gmail.com> (raw)
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
