| * Xen hypervisor device tree bindings |
| |
| Xen ARM virtual platforms shall have a top-level "hypervisor" node with |
| the following properties: |
| |
| - compatible: |
| compatible = "xen,xen-<version>", "xen,xen"; |
| where <version> is the version of the Xen ABI of the platform. |
| |
| - reg: specifies the base physical address and size of a region in |
| memory where the grant table should be mapped to, using an |
| HYPERVISOR_memory_op hypercall. The memory region is large enough to map |
| the whole grant table (it is larger or equal to gnttab_max_grant_frames()). |
| |
| - interrupts: the interrupt used by Xen to inject event notifications. |
| A GIC node is also required. |
| |
| |
| Example (assuming #address-cells = <2> and #size-cells = <2>): |
| |
| hypervisor { |
| compatible = "xen,xen-4.3", "xen,xen"; |
| reg = <0 0xb0000000 0 0x20000>; |
| interrupts = <1 15 0xf08>; |
| }; |
