    Tilck

    Tilck

    A Tiny Linux-Compatible Kernel

    Tilck is a tiny, monolithic operating system kernel designed to be partially compatible with Linux at the binary level while maintaining extreme simplicity, low latency, and minimal resource usage. It is built primarily as an educational project, allowing developers to experiment with kernel development while still being able to run real Linux user-space applications without modification. The kernel is written in C and designed to run on architectures such as i686 and RISC-V, with future plans for broader hardware support. One of its defining characteristics is its deterministic behavior and very small memory footprint, enabling it to run on systems with extremely limited resources. Unlike Linux, tilck intentionally avoids complexity and large-scale features, focusing instead on clarity, robustness, and ease of understanding. It includes its own bootloader and supports integration with existing ones like GRUB, making it flexible for experimentation.

    Linux NTFS file system support

    Development moved to https://sourceforge.net/projects/ntfs-3g/

    Development on this project has moved to https://sourceforge.net/projects/ntfs-3g/ The goals of this project are: create a new Linux kernel driver for the NTFS file system (1.2, 3.x, and later), user space utilities (e.g. format, ntfs check, etc.) and a library to avoid code duplication and provide access to NTFS to other GPL programs.

    NVIDIA Linux Open GPU Kernel Module

    NVIDIA Linux Open GPU Kernel Module

    NVIDIA Linux open GPU kernel module source

    This is the source release of the NVIDIA Linux open GPU kernel modules, version 530.41.03. Note that the kernel modules built here must be used with GSP firmware and user-space NVIDIA GPU driver components from a corresponding 530.41.03 driver release. Currently, the kernel modules can be built for x86_64 or aarch64. If cross-compiling, set these variables on the make command line. Any reasonably modern version of GCC or Clang can be used to build the kernel modules. Note that the kernel interface layers of the kernel modules must be built with the toolchain that was used to build the kernel. This code base is shared with NVIDIA's proprietary drivers, and various processing is performed on the shared code to produce the source code that is published here. When packaged in the NVIDIA .run installation package, the OS-agnostic component is provided as a binary.

    ELKS is a subset of the Linux kernel that runs on IBM compatible PCs from 8086 up. It is intended to get use out of obsolete old hardware, for use in embedded systems, and as an educational tool. ELKS has been moved to Github to protest SourceForge's installer adware hijacking. This does not directly affect ELKS, but it does affect many major open source projects such as Gimp and FileZilla by attempting to trick the user into installing adware in order to download these programs. I refuse to leave ELKS here with such policies in effect. If you have questions about this, please email jody@c02ware.com.
