From: Eugenio Pérez Date: Fri, 3 Mar 2023 17:24:44 +0000 (+0100) Subject: vdpa net: allow VHOST_F_LOG_ALL X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=609ab4c3ed8d6b6a4d94930fb9185412b2ba0d0c;p=qemu.git vdpa net: allow VHOST_F_LOG_ALL 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.
