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			`mkdir mnt`

Start adding a basic /proc filesystem and a "ps" utility. 2018-10-23 12:57:38 +03:00			`cp ../Userland/id mnt/bin/id`
			`cp ../Userland/ps mnt/bin/ps`
Add simplified mmap() and munmap() syscalls. 2018-10-24 10:48:24 +03:00			`cp ../Userland/ls mnt/bin/ls`
Add a "pwd" utility to userland. It's implemented as a separate process. How cute is that. Tasks now have a current working directory. Spawned tasks inherit their parent task's working directory. Currently everyone just uses "/" as there's no way to chdir(). 2018-10-24 15:28:22 +03:00			`cp ../Userland/pwd mnt/bin/pwd`
