# Introduction Matos is a simple OS. It's targetting x86 and inspirated by http://sos.enix.org/fr/PagePrincipale ![screenshot](https://git.mathux.org/mathieu/matos/raw/branch/master/screenshot_1.png) # Dependencies To generate iso image * `mtools xorriso (which is libisoburn on ArchLinux)` * gcc >= 6 * sfdisk (util-linux) # Run it `make run` or `make fd.iso && qemu-system-x86_64 -cdrom fd.iso` you can also test it `make test` # Debug gdb could be launch with debug symbols using : `make debug` Serial log will be saved in the `serialOut` file. Then you can check some matos specific commands or pretty printing with `help user-defined` `info pretty-printer` (Should contains matos_pretty_printers) # Change Disk partitions You can either modify the disk.sfdisk file or modify the disk image with your favorit tool (e.g. gparted) and re-generate disk.sfdisk sfdisk -d > disk.sfdisk # Multiboot In arch/x86/boot, you can choose the assembly used to start the C part by removing the .opt extension * boot.asm: intel syntax with multiboot support * boot.S: GNU As syntax with multiboot support * boot_multiboot2.S: GNU As syntax with multiboot2 support /!\ multiboot2 is not supported by qemu for -kernel option (https://gitlab.com/qemu-project/qemu/-/issues/389). So you may have to use the fd.iso image and modify the grub configuration from `multiboot /boot/kernel` to `multiboot2 /boot/kernel` # Features * VGA Driver * keyboard Driver * Serial Driver * Timer * Virtual memory * Allocator * Multithread (Full preempt) * Mutex * ATA * basic userspace with syscall # TODO * ringbuffer protected by mutex * blocking read
