Routix is a POSIX compliant monolithic Kernel written more than 10 years ago in order to learn (trough hands-on) the i386 architecture and how an Operating System is written.

Most of the comments were done in Spanish ( sorry about that ).

The OS implements:

1. FAT 16 fs
2. Syscalls:
3. Console:
   • int sys_gets (char *str);
   • int sys_print (void *buff, size_t largo);
   • int sys_clrscr (void);
4. Process:
   • int sys_fork (void);
   • int sys_void (void);
   • int sys_exec (char *nombre);
   • void sys_perror (char *str);
   • int sys_renice (word pid, word prioridad);
   • inline pid_t sys_get_pid (void);
   • inline pid_t sys_get_ppid (void);
   • void sys_exit (int);
   • void sys_show (int);
   • pid_t sys_wait(int *);
   • pid_t sys_waitpid (pid_t pid, int *status, int options);
5. Timers
   • int sys_sleep(int segundos);
   • int sys_usleep(int usegundos);
   • int sys_proc_dump(void);
   • extern int sys_kill(pid_t pid, int sig);
   • int sys_proc_dump_v(int);
   • int sys_timer_dump(void);
6. Memory Management
   • void *sys_malloc_page(void);
   • int sys_free_page(void *);
   • dword sys_free_mem (void);
7. A small C library was implemented so it is possible to build a Routix executable with GCC linking against Routix lib C library. The only executable format supported is COFF32

The project has been migrated from Source Forge CVS (http://sourceforge.net/projects/routix/) so some annotations and tracking history may be wrong/missing
