Latest patch for PCI shared memory device that maps a host shared memory object
to be shared between guests.
new in this series
- fixed segfault for non-server case
- code style fixes
- removed limit on the number of guests
- shared memory server is now in qemu.git/contrib
- made irqfd/ioeventfd setup functions generic
- removed interrupts when guest joined (let application handle it)
v4:
- 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 (5):
