DomU ACPI module
|
|
================================
|
|
|
|
Xen toolstack passes the domU ACPI tables via a reference in the /chosen node of
|
|
the device tree.
|
|
|
|
Each node contains the following properties:
|
|
|
|
- compatible
|
|
|
|
"xen,guest-acpi", "multiboot,module"
|
|
|
|
- reg
|
|
|
|
Specifies the physical address and the length of the module.
|
|
RSDP table is always located at the beginning of this region.
|
|
|
|
Examples
|
|
========
|
|
|
|
module@0x20000000 {
|
|
compatible = "xen,guest-acpi", "multiboot,module";
|
|
reg = <0x20000000 0x1234>;
|
|
};
