Public bug reported:
KVMGT gvt-g Live Migration is a valuable feature for a variety of use
cases like load balancing, hardware failover, energy saving and
geographic migration. To enable VGPU live migration, one new region is
designed for vfio_mdev device status save and restore during the
migration. And one new ioctl is added to help do the mdev device dirty
page synchronization. Correspondingly, GVT implements a function to
save/retore the device context in the new region.
Applied platform: BDW/SKL/KBL
Business value: Improve efficiency and reduce cost in VM maintenance by
enabling live migration for Intel GPU accelerated VM.
