[PATCH v3 0/5] WIP: ramfb: migration support

Posted by marcandre.lureau@redhat.com 7 months ago

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Hi,

Implement RAMFB migration, and add properties to enable it only on >= 8.2
machines, + a few related cleanups.

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)

Fixes:
https://bugzilla.redhat.com/show_bug.cgi?id=1859424

Marc-André Lureau (5):
  hw/core: remove needless includes
  hw/pc: remove needless includes
  ramfb: add migration support
  ramfb-standalone: add migration support
  hw/vfio: add ramfb migration support
