🏢 An operating system that combine the desire of UNIX utopia from the 1970s with modern technology and engineering

Overview



Striking modernist shapes and bold use of modern C are the hallmarks of BRUTAL.
BRUTAL combine the desire of UNIX utopia from the 1970s with modern technology and engineering.


About

BRUTAL is a micro-kernel base operating system targeting the x86_64 architecture. ARM and Risc-V support is planned.

Roadmap

Right now the main goal of brutal is to run doom.

See the roadmap file for more information on how we plan to get there and where you can contribute.

Modern C

Brutal is written in a dialect of C called modern C characterize by the following principle:

  • Avoid pointers and prefer value semantic.
  • The standard library is old and unsafe, don't use it.
  • Don't be afraid of writing type generic code.

Here is more resources on the subject:

    Make it compile on macOS (Monterey)

    I used this configuration to compile it under macOS (Monterey).

    I need to obtain the following dependencies on my local system to compile it.

    brew install qemu nasm xorriso llvm binutils wget

    Then I run it via ./brutal.sh -r to open the qemu window.

    Building on macOS

    When I try to build it on macOS, it works fine for the most part. However, it always now ends in this:

    make: *** No rule to make target `/opt/homebrew/Cellar/llvm/13.0.0_1/lib/clang/13.0.0/share/asan_ignorelist.txt', needed by `bin/arm64-llvm/host/embed/posix/err.c.o'.  Stop.
    

    How do I fix this, or get around this?

    Feat: add basic EFI library

    I added a basic EFI library for the work-in-progress bootloader.

    I am using my own printf-like thing because for a certain reason, fmt wouldn't want to work with utf16. I also implemented my own strncpy since yours is broken (add a '\0' at the end of the string).

  • Feature suggestion: Add source code comments

    Feature suggestion: Add source code comments

    Currently, the majority of the .C source code is undocumented.

    Consider that it's often easier to expose oneself to the concepts of a new application when the source can be scanned quickly, and the high-level concepts ingested as fast as possible; if going deeper is needed, the actual code is just a few lines away.

    • now you can iterate multiple time in a test
    • now if a test doesn't succeed, print the exit value
    • added gfx tests
    • now you can dump all the tests names
    • For gfx_brutal_logo_rotated, use iteration instead of time, thus making the test always behaving the same way.
