| * 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>; | |
| }; | |
| }; | |
