Lots of hacking: - Turn Keyboard into a CharacterDevice (85,1) at /dev/keyboard. - Implement MM::unmapRegionsForTask() and MM::unmapRegion() - Save SS correctly on interrupt. - Add a simple Spawn syscall for launching another process. - Move a bunch of IO syscall debug output behind DEBUG_IO. - Have ASSERT do a "cli" immediately when failing. This makes the output look proper every time. - Implement a bunch of syscalls in LibC. - Add a simple shell ("sh"). All it can do now is read a line of text from /dev/keyboard and then try launching the specified executable by calling spawn(). There are definitely bugs in here, but we're moving on forward. 2018-10-23 11:12:50 +03:00			`int open(const char* path);`

Add a simplified waitpid() so that sh can wait on spawned commands. 2018-10-24 01:20:34 +03:00			`pid_t waitpid(pid_t);`
