From f756dd3e2a4c704c0ab5ecb143ab71f1249af497 Mon Sep 17 00:00:00 2001 From: Dragos Tatulea Date: Mon, 25 Dec 2023 17:12:01 +0200 Subject: vdpa/mlx5: Use vq suspend/resume during .set_map MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of tearing down and setting up vq resources, use vq suspend/resume during .set_map to speed things up a bit. The vq mr is updated with the new mapping while the vqs are suspended. If the device doesn't support resumable vqs, do the old teardown and setup dance.
