From 609ab4c3ed8d6b6a4d94930fb9185412b2ba0d0c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Eugenio=20P=C3=A9rez?= Date: Fri, 3 Mar 2023 18:24:44 +0100 Subject: vdpa net: allow VHOST_F_LOG_ALL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since some actions move to the start function instead of init, the device features may not be the parent vdpa device's, but the one returned by vhost backend. If transition to SVQ is supported, the vhost backend will return _F_LOG_ALL to signal the device is migratable. Add VHOST_F_LOG_ALL. HW dirty page tracking can be added on top of this change if the device supports it in the future.
