SeaKernel A simple unix-like kernel designed for simplicity and speed, with a nod towards research concepts. In it's current iteration, it is a monolithic kernel with loadable module support. Features Overview ----------------- Some primary features include: * Kernel-level threading support (incomplete) * SMP support * Multiprocess scheduling (preemptive) * Unix-like syscalls and a standard C library support * Loadable and unloadable modules * ATA hard drives * ext4 file systems * access to devices via /dev filesystem * ELF binaries * user-mode protections * ix86 processors * unix style IPC History ------- SeaKernel was started in 2008 as a hobby, and went through several different iterations and re-writes until its current iteration, which was started in late 2011. Since then, it has seen an increase in complexity and features. Usage Instructions ------------------ You need to have a cross compiler installed (typically i586-pc-seaos-gcc) to build the kernel. This is built automatically by the SeaOS userspace system, available on github (dbittman/sea). After initializing, The kernel will try to run a script in a ramdisk (sh /preinit.sh). The ramdisk should provide a minimum of a shell and the init script. Build Instructions ------------------ Building is handled via gmake (make). The available targets are: - deps: generate Dependency information for the build system - skernel: build the kernel (requires deps to have been built) - modules: build all configured modules - initrd.img: build the initial ram disk - kernel: skernel, modules, and initrd.img - config: run the configuration system (interactive) - defconfig: generate the default configuration - clean: clean compiled files - distclean: clean everything - doc: generate documentation into human-readable format(s) - all: deps and kernel - install: install the kernel on a SeaOS system Generally, a good order for this would be: make config all
