3 QEMU's emulation / virtualization targets provide the following PVPANIC
4 MMIO Configuration interface on the "virt" machine.
5 type:
6
7 - a read-write, 16-bit wide data register.
8
9 QEMU exposes the data register to guests as memory mapped registers.

13 - compatible: "qemu,pvpanic-mmio".
14 - reg: the MMIO region used by the device.
15 * Bytes 0x0 Write panic event to the reg when guest OS panics.

20 / {
21 #size-cells = <0x2>;
22 #address-cells = <0x2>;

24 pvpanic-mmio@9060000 {
25 compatible = "qemu,pvpanic-mmio";
26 reg = <0x0 0x9060000 0x0 0x2>;
