From aeae94579caf77406a8a235ea33fdb67abe9a57e Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Sun, 17 Jun 2018 13:00:04 +0300 Subject: IB/mlx5: Add DEVX support for memory registration Add support to register a memory with the firmware via the DEVX interface. The driver translates a given user address to ib_umem then it will register the physical addresses with the firmware and get a unique id for this registration to be used for this virtual address.
