Most Android devices also run some OS on the baseband processor (on-die or separate), and often the Wifi, Codecs, Bluetooth, Power Management blocks, etc also run their own little OSes. It's getting a little crazy, how many distinct cores exist on these devices. Magenta was based on LK but it is definitely its own thing and is evolving in its own directions (64bit, SMP, userspace, etc). LK is generally MCU-targeted and can be very tiny (15-20K for a minimal system used for bootloader cores or tiny embedded things). |
