Subject: [PATCH for-next v2 0/2] RDMA/rxe: Prefetching pages with explicit ODP
Date: Sat, 3 May 2025 13:42:22 +0000 [thread overview]
Message-ID: <20250503134224.4867-1-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
