Telos is a simple x86 kernel, supporting:
- preemptive multitasking
- processes running in kernel- and user-mode
- copy-on-write and demand paging
- a virtual filesystem layer
- memory-mapped files
- POSIX signals
- POSIX timers
- ...and more
You'll need the i386-telos toolchain. It can be obtained by checking out the telos-build repository and following the instructions in the README.
Once the toolchain is installed, the kernel may be built by running make in
this directory.
$ make
Telos requires an initial RAM disk to be loaded by the bootloader. Building an initrd is outside the scope of this repository. See the telos-initrd repository for an initrd suitable for use with Telos. If you checked out telos-build earlier, you should already have this.
Telos is a multiboot kernel, so it should be possible to load it in any bootloader implementing the multiboot standard. QEMU is known to work, and a script to run the kernel in QEMU is provided by telos-build.
