This patch add support for dumping guest memory using dump-guest-memory monitor command. Before patch: (qemu) dump-guest-memory testcrash this feature or command is not currently supported (qemu) After patch: (qemu) dump-guest-memory testcrash (qemu) crash was able to read the file crash> bt PID: 0 TASK: c000000000c0d0d0 CPU: 0 COMMAND: "swapper/0" R0: 0000000028000084 R1: c000000000cafa50 R2: c000000000cb05b0 R3: 0000000000000000 R4: c000000000bc4cb0 R5: 0000000000000000 R6: 001efe93b8000000 R7: 0000000000000000 R8: 0000000000000000 R9: b000000000001032 R10: 0000000000000001 R11: 0001eb2117e00d55 .... ...
