[PATCH v6 6/8] vfio/migration: Store VFIO migration flags in VFIOMigration |
Date: |
Wed, 21 Jun 2023 14:11:59 +0300 |
VFIO migration flags are queried once in vfio_migration_init(). Store
them in VFIOMigration so they can be used later to check the device's
migration capabilities without re-querying them.
This will be used in the next patch to check if the device supports
precopy migration.
