behavior:
(gdb) maintenance packet Qqemu.sstep=0x5
sending: "qemu.sstep=0x5"
received: "OK"
+
+
+Another feature that QEMU gdbstub provides is to toggle the memory GDB
+works with, by default GDB will show the current process memory respecting
+the virtual address translation.
+
+If you want to examine/change the physical memory you can set the gdbstub
+to work with the physical memory rather with the virtual one.
+
+The memory mode can be checked by sending the following command:
+
+``maintenance packet qqemu.PhyMemMode``
+ This will return either 0 or 1, 1 indicates you are currently in the
+ physical memory mode.
+
+``maintenance packet Qqemu.PhyMemMode:1``
+ This will change the memory mode to physical memory.
+
+``maintenance packet Qqemu.PhyMemMode:0``
+ This will change it back to normal memory mode.
