Subject: [Qemu-devel] [PATCH v4 12/13] vfio: Make vfio-pci device migration capable.
Date: Thu, 20 Jun 2019 20:07:40 +0530 [thread overview]
Message-ID: <1561041461-22326-13-git-send-email-kwankhede@nvidia.com> (raw)
In-Reply-To: <1561041461-22326-1-git-send-email-kwankhede@nvidia.com>
Call vfio_migration_probe() and vfio_migration_finalize() functions for
vfio-pci device to enable migration for vfio PCI device.
Removed vfio_pci_vmstate structure.
