+# Other architectures
+
+The portability of the kernel and toolchains is amazing: change an option and most things magically work on completely different hardware.
+
+## arm
+
+First build:
+
+    ./run -a arm
+
+Run without build:
+
+    ./runqemu -a arm
+
+Debug:
+
+    ./runqemu -a arm -d
+    # On another terminal.
+    ./rungdb -a arm
+
+TODOs:
+
+-   only managed to run in the terminal interface (but weirdly a blank QEMU window is still opened)
+-   GDB not connecting to KGDB. Possibly linked to `-serial stdio`. See also: <https://stackoverflow.com/questions/14155577/how-to-use-kgdb-on-arm>
+
+## aarch64
+
+    ./run -a aarch64
+
+TODOs:
+
+-   GDB gives a ton of messages:
+
+        no module object found for ''
+
+    when you connect. `Ctrl + C` then `c` works though.
+
+-   How to add devices to `-M virt` as we did for `-M versatilepb`
+
+## mips64
+
+    ./run -a mips64
