From b6662cb7e5376659c7abb56efe27dcf3898d4fe6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Eugenio=20P=C3=A9rez?= Date: Fri, 3 Mar 2023 18:24:36 +0100 Subject: vdpa: add vhost_vdpa->suspended parameter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This allows vhost_vdpa to track if it is safe to get the vring base from the device or not. If it is not, vhost can fall back to fetch idx from the guest buffer again. No functional change intended in this patch, later patches will use this field.
