[Qemu-devel] [PATCH v4 0/3] PCI Shared memory device

[Cam Macdonell]

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

Cam Macdonell (3):
  Device specification for shared memory PCI device
  Support adding a file to qemu's ram allocation
  Inter-VM shared memory PCI device
