1 Inter-VM Shared Memory Flat Device
2 ----------------------------------
4 The ivshmem-flat device is meant to be used on machines that lack a PCI bus,
6 a PCI device. Machines like those with a Cortex-M MCU are good candidates to use
7 the ivshmem-flat device. Also, since the flat version maps the control and
12 Similar to the ivshmem device, the ivshmem-flat device supports both peer
13 notification via HW interrupts and Inter-VM shared memory. This allows the
