Hi,
Implement RAMFB migration, and add properties to enable it only on >= 8.2
machines, + a few related cleanups.
Should this series go in vfio-next ?
Thanks,
C.
thanks
v5:
- add missing VMSTATE_END_OF_LIST
- changed ramfb=off & x-mig=on user config error to a warning
- add r-b tags
v4: (Laszlo review and suggestions)
- change migrate_needed() to assert(ramfb_exists)
- rename vfio_display_needed() to vfio_display_migration_needed(),
update the condition and associated comment
- move the ramfb-migrate option check and add a check for ramfb=on
- add a stub to fix compilation on some architectures
v3:
- add a "x-" prefix to properties, as they are not meant for users.
- RAMFB now exports a ramfb_vmstate for actual devices to include
- VFIOPCIDevice now has a VFIODisplay optional subsection whenever ramfb
migration is required (untested)
