The Twizzler Operating System
Twizzler is a research operating system designed to explore novel programming models for new memory hierarchy designs. We are focused on providing an environment designed around invariant data references and long-lived pointers, thus being well suited for byte-addressible non-volatile memory and multi-node networked applications.
This repo contains source code for the kernel and userspace, along with a build system that bootstraps a Twizzler userspace. You can write code for it and play around! We're not quite production ready, but we're getting there! :)
See (https://twizzler.io/about.html) for more details.
NOTE: This repo has recently been rebuilt with our pure Rust implementation of the Twizzler kernel. If you have previously forked or used Twizzler you may find that some features are changed or not at parity. Please open an issue on our tracker if you find any deficiencies.
See BUILD.md for details.
See develop.md for details.
All bugs found and features requested must be reported through our github issue tracker. Please add the appropriate label,
feature, and also give as much detail as possible, including backtraces or such for bugs.
If you find a security vulnerability that needs responsible disclosure please contact the administrators of the project directly and we will work with you on the fix and the disclosure credit.
