1 * Xen hypervisor reserved-memory binding
3 Expose one or more memory regions as reserved-memory to the guest
4 virtual machine. Typically, a region is configured at VM creation time
5 to be a shared memory area across multiple virtual machines for
6 communication among them.
8 For each of these pre-shared memory regions, a range is exposed under
9 the /reserved-memory node as a child node. Each range sub-node is named
10 xen-shmem@<address> and has the following properties:
13 compatible = "xen,shared-memory-v1"
16 the base guest physical address and size of the shared memory region
18 - xen,offset: (borrower VMs only)
19 64 bit integer offset within the owner virtual machine's shared
20 memory region used for the mapping in the borrower VM.
23 a string that identifies the shared memory region as specified in
