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`
			`mount -o loop _fs_contents mnt/`
			`cp ../Userland/sh mnt/bin/sh`
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`
Add a "sleep" syscall that sleeps for N seconds. 2018-10-25 14:53:49 +03:00			`cp ../Userland/sleep mnt/bin/sleep`
Add gettimeofday() syscall and LibC wrappers gettimeofday() and time(). This only has second accuracy right now, I'll work out subseconds later. 2018-10-25 18:29:49 +03:00			`cp ../Userland/date mnt/bin/date`
Add /bin/false and /bin/true for fun. :^) 2018-10-25 22:39:37 +03:00			`cp ../Userland/true mnt/bin/true`
			`cp ../Userland/false mnt/bin/false`
Add sys$gethostname and /bin/hostname 2018-10-26 10:54:29 +03:00			`cp ../Userland/hostname mnt/bin/hostname`
Implement argc/argv support for spawned tasks. Celebrate the new functionality with a simple /bin/cat implementation. :^) 2018-10-26 12:16:56 +03:00			`cp ../Userland/cat mnt/bin/cat`
Add sys$uname() and a /bin/uname utility. 2018-10-26 15:56:21 +03:00			`cp ../Userland/uname mnt/bin/uname`
Add a /bin/clear that prints the clear terminal escape sequence. It doesn't work yet, but it will! 2018-10-27 18:39:08 +03:00			`cp ../Userland/clear mnt/bin/clear`
Add a very hackish /proc/PID/stack. It walks the stack and identifies anything that looks like a kernel symbol. This could be a lot more sophisticated. 2018-10-26 23:32:35 +03:00			`cp kernel.map mnt/`
