1 | * QEMU PVPANIC MMIO Configuration bindings |
2 | ||
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. | |
10 | ||
11 | Required properties: | |
12 | ||
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. | |
16 | * Bytes 0x1 Reserved. | |
17 | ||
18 | Example: | |
19 | ||
20 | / { | |
21 | #size-cells = <0x2>; | |
22 | #address-cells = <0x2>; | |
23 | ||
24 | pvpanic-mmio@9060000 { | |
25 | compatible = "qemu,pvpanic-mmio"; | |
26 | reg = <0x0 0x9060000 0x0 0x2>; | |
27 | }; | |
28 | }; | |
