Subject: [Qemu-devel] [PATCH 0/2] dataplane: RCU dirty memory bitmap for safe RAM hotplug
Date: Mon, 25 Jan 2016 13:33:19 +0000 [thread overview]
Message-ID: <1453728801-5398-1-git-send-email-stefanha@redhat.com> (raw)
Make RAM hotplug play nicely with dataplane. By RCU-protecting the dirty
memory bitmap it is possible to hotplug RAM while other threads are dirtying
guest RAM.
See Patch 1 for the meat of the code. Patch 2 is just a fixup on top of
Paolo's dataplane branch.
This series is based on: https://github.com/bonzini/qemu.git dataplane
