Subject: [Qemu-devel] [PATCH v4 0/3] PCI Shared memory device
Date: Wed, 7 Apr 2010 16:51:57 -0600 [thread overview]
Message-ID: <1270680720-8457-1-git-send-email-cam@cs.ualberta.ca> (raw)
Latest patch for PCI shared memory device that maps a host shared memory object
to be shared between guests
new in this series
- moved to single Doorbell register and use datamatch to trigger different
VMs rather than one register per eventfd
- remove writing arbitrary values to eventfds. Only values of 1 are now
written to ensure correct usage
