Syscall reboot

User Mode

#include <sys/reboot.h>
extern ssize_t reboot(int32_t cmd);

# cmd:
#define VIMIX_REBOOT_CMD_POWER_OFF 0
#define VIMIX_REBOOT_CMD_RESTART 1

Reboots or halts the system. Only root can call this.

User Apps

The app shutdown exposes this syscall.

Kernel Mode

Implemented in sys_system.c as sys_reboot(). Warning: Shuts off hard, ideally the OS would write all outstanding transactions to disk first or kill all processes first, etc.
