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			`mount -o loop _fs_contents mnt/`
Add getpwent() family of functions to LibC. Also add a little /etc/passwd database. There's just me in there. 2018-10-31 21:49:22 +03:00			`cp -R ../Base/* 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`
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 save/unsave cursor escape sequences. Also added a little terminal test program called /bin/tst. 2018-10-28 02:44:53 +03:00			`cp ../Userland/tst mnt/bin/tst`
Implement fork()! This is quite cool! The syscall entry point plumbs the register dump down to sys$fork(), which uses it to set up the child process's TSS in order to resume execution right after the int 0x80 fork() call. :^) This works pretty well, although there is some problem with the kernel alias mappings used to clone the parent process's regions. If I disable the MM::release_page_directory() code, there's no problem. Probably there's a premature freeing of a physical page somehow. 2018-11-02 22:41:58 +03:00			`cp ../Userland/ft mnt/bin/ft`
Replace zones with individually tracked physical pages. It's just a simple struct { ref_count, paddr }. This will allow me to implement lazy zeroing and COW pages. 2018-11-05 12:23:00 +03:00			`cp ../Userland/ft2 mnt/bin/ft2`
Add /proc/mm and a /bin/mm utility that just dumps it. This shows some info about the MM. Right now it's just the zone count and the number of free physical pages. Lots more can be added. Also added "exit" to sh so we can nest shells and exit from them. I also noticed that we were leaking all the physical pages, so fixed that. 2018-10-28 12:26:07 +03:00			`cp ../Userland/mm mnt/bin/mm`
Implement basic sys$kill() and add a /bin/kill All it can do right now is send SIGKILL which just murders the target task. 2018-10-31 03:06:57 +03:00			`cp ../Userland/kill mnt/bin/kill`
Add a /bin/tty command that prints the current tty. Also fix ttyname() syscall to include "/dev/" in the name. 2018-10-31 23:45:36 +03:00			`cp ../Userland/tty mnt/bin/tty`
Add strsignal() and improve sharing signal numbers between LibC and kernel. 2018-11-06 17:45:16 +03:00			`cp ../Userland/strsignal mnt/bin/strsignal`
Enough compatibility work to make figlet build and run! I ran out of steam writing library routines and imported two BSD-licensed libc routines: sscanf() and getopt(). I will most likely rewrite them sooner or later. For now I just wanted to see figlet running. 2018-10-31 19:50:43 +03:00			`sh sync-local.sh`
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/`
