* QEMU PVPANIC MMIO Configuration bindings
|
|
|
|
QEMU's emulation / virtualization targets provide the following PVPANIC
|
|
MMIO Configuration interface on the "virt" machine.
|
|
type:
|
|
|
|
- a read-write, 16-bit wide data register.
|
|
|
|
QEMU exposes the data register to guests as memory mapped registers.
|
|
|
|
Required properties:
|
|
|
|
- compatible: "qemu,pvpanic-mmio".
|
|
- reg: the MMIO region used by the device.
|
|
* Bytes 0x0 Write panic event to the reg when guest OS panics.
|
|
* Bytes 0x1 Reserved.
|
|
|
|
Example:
|
|
|
|
/ {
|
|
#size-cells = <0x2>;
|
|
#address-cells = <0x2>;
|
|
|
|
pvpanic-mmio@9060000 {
|
|
compatible = "qemu,pvpanic-mmio";
|
|
reg = <0x0 0x9060000 0x0 0x2>;
|
|
};
|
|
};
