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:

./build -a arm
./run -a arm

Debug:

./run -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

./build -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

./build -a mips64
