Subject: [Qemu-devel] [PATCH 2/2] vmstate, memory: decouple vmstate from memory API
Date: Tue, 20 Dec 2011 16:05:14 +0200 [thread overview]
Message-ID: <1324389914-12246-3-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1324389914-12246-1-git-send-email-avi@redhat.com>
Currently creating a memory region automatically registers it for
live migration. This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core.
Decouple the two by introducing a separate API, vmstate_register_ram(),
for registering a RAM block for migration. Currently the same
implementation is reused, but later it can be moved into a separate list,
and registrations can be moved to VMStateDescription blocks.
