## Stability and Performance Improvements
Jeremy Soller and 4lDO2 did massive improvements to stability and security, fixed many bugs, from easy to very hard.
Jeremy Soller and 4lDO2 have made huge improvements to stability and security, fixed many bugs, from easy to very hard, and added several new crates and components to encapsulate common elements.
We would like to thank 4lDO2 a lot for his massive work to improve the kernel and user-space daemons.
Some of his work includes:
You can read about part of the 4lDO2 journey to improve the kernel on the following posts:
- Paging and memory management
- Scheme deamon API encapsulation and refactoring
- Process lifecycle and signal management (our NLnet project)
- Context switching performance improvements
- First steps in implementing the "Stable ABI" strategy
- Being a key resource for the Redox community
You can read about parts of 4lDO2's journey to improve the kernel in the following posts:
- [RSoC: on-demand paging](https://www.redox-os.org/news/kernel-8/)
- [RSoC: on-demand paging II](https://www.redox-os.org/news/kernel-9/)
- [Significant performance and correctness improvements to the kernel](https://www.redox-os.org/news/kernel-10/)
- [Towards userspaceification of POSIX - part I: signal handling and IO](https://www.redox-os.org/news/kernel-11/)
Jeremy rarely write posts and prefer to contribute in silence and report the progress later in the Matrix community.
## Drivers and Boot
## Software Updates
Jeremy, 4lDO2 and bjorn3 all worked on improving drivers and boot, and several other people made important contributions.
Some of bjorn3's contributions include:
Our toolchains received some updates and currently our Rust, C and C++ toolchains use the latest stable versions or close to it, it's a great achievement compared to other OS projects that use very old toolchain versions (limiting the program compatibility)
- Improved boot correctness for UEFI
- Improvements and bug fixes for many PCI/PCIe drivers
- Removing all the old format paths and replacing them with the new format
- General code cleanup and update of drivers
- Move the driver folders to categories
Beyond the toolchain updates, we also updated important cross-platform libraries used by most programs and some important programs.
Many thanks to bjorn3 and all our driver contributors!
## Rust-first Program Porting!
## Relibc Improvements
We focus on Rust programs as they are more easy to port, Ribbon quickly ported hundreds of emerging Rust programs in 2023.
Relibc is the Redox C Standard Library, an alternative to the POSIX libc, glibc and musl.
Relibc is written in Rust, and provides standard C and POSIX APIs, as well as many libc utility functions.
It was originally envisioned to be an alternative to libc for both Linux and Redox.
Increasingly, it has been the home for many Redox system services, including such things as fork, exec, pthred, and signal handling,
as we try to move functionality out of the kernel while still supporting POSIX APIs.
Many of the services have an underlying kernel or daemon scheme that implements part of the functionality,
but the scheme may have little of the service's complexity.
Relibc is also now key to our "stable ABI" strategy.
The plan is for files to dynamically link against Relibc, which will provide a stable ABI for the dynamic linker.
New POSIX functions will be added to Relibc, but none will be removed.
That will leave us free to change the implementation of the services as Redox evolves,
but still be able to run binaries compiled for older Redox versions.
4lDO2 has started the first phase of creating the stable ABI,
creating a consistent internal API for current kernel services.
He has also started to refactor relibc to separate services from APIs,
and to make it easier to provide a non-POSIX API for system services in the future.
Not to mention his extensive work on the NLnet-funded Signals and Process Lifecycle project,
including moving signal handling into Relibc.
And thank you to all our other Relibc contributors, who have implemented many libc functions,
tremendously helping our effort to port Linux/BSD software.
Special thanks to Darley Barreto, who has worked hard to remove any remaining C code from libc,
partitioning out libm (which is still largely in C) and replacing our malloc implementation with dlmalloc-rs.
## Better ARM64 Support
The contributor uvnn cleaned and improved our ARM64 support a lot, we would like to thank his massive work in 2023.
Ivan Tan got Redox to boot on the Raspberry Pi 3 B+,
and helped us improve the build tools to support multiple Raspberry Pi devices and other ARM platforms.
ARM is a different challenge than x86_64, because there is little standardization of hardware platforms.
We hope to get Redox running on more ARM64 hardware in the future.
## C/C++ Programs
Jeremy also improved the ARM support to the level where we can start the Orbital session on the QEMU emulation.
Ribbon also partially-ported the classic and widely-used C and C++ programs and libraries, he focused to package the most used (and best) programs of the Linux/BSD world.
## A Note about USB Support
Currently there are around 1,700 work-in-progress software ports, we need to write cross-compilation scripts and port/update some libraries to make them work.
USB support is under heavy development and is a key feature for us, but it did not quite make the cut for this release.
We hope to have an update for USB HID in the near future,
which will provide support for USB mouse and keyboard, as well as game controllers.
This will be followed by USB hub support, which is essential, as many motherboards route some or all USB ports through
an internal hub.
Then we will start work on USB storage.
## Relibc Improvements
Thanks to Jeremy and 4lDO2 for their work on this, and special thanks to new contributor Tim Finnegan for his emergency work
to try to squeeze this in under the wire.
The Redox contributors improved relibc a lot, from new functions to important bug fixes.
Watch for [News](https://redox-os.org/news/) about USB!
This increased our software compatibility and fixed many programs, from Rust to C/C++
## VirtIO Support
## Better ARM Support
Anhad Singh from the [Aero OS](https://github.com/Andy-Python-Programmer/aero) project participated in our RSoC program from 2023 to write VirtIO drivers for Redox.
uvnn cleaned and improved our ARM support a lot, we would like to thank his massive work in 2023.
You can read about his work on the following posts:
We also would like to thank Ivan Tan to achieve the Redox support on the Raspberry Pi 3 B+ !
- [RSoC: virtio drivers - 1](https://www.redox-os.org/news/rsoc-virtio-1/)
- [RSoC: virtio drivers - 2](https://www.redox-os.org/news/rsoc-virtio-2/)
Jeremy also improved the ARM support to the level where we can start the Orbital session on the QEMU emulation.
## Self-Hosting Improvements
## Better PCI Express Support
The NLnet-funded Signals and Process Lifecycle work has had the key side-effect of improving the operation of
many software tools.
The Rust and GCC toolchains are able to build basic programs, but with some limitations.
Self-hosting the build is high on our agenda, and these improvements have helped us take a huge leap forward.
We would like to thank bjorn3 for his excellent work to improve our PCI Express support.
## Software Updates
## Better Driver Organization and Code Cleanup
Our toolchains received some updates and currently our Rust, C and C++ toolchains are all recent versions,
which significantly improves compatibility when porting other Linux/POSIX and Rust software.
bjorn3 cleaned our driver code, deduplicated some drivers and moved our driver code to category folders, like Linux and BSD.
We also updated important cross-platform libraries and improved the build process for programs that depend on those libraries,
greatly simplifying the job of porting applications.
## Better USB Support!
## Rust-first Program Porting!
Jeremy and 4lDO2 improved our USB support to the level where most USB HID devices can work!
We have been focusing our initial porting efforts on Rust programs as they are easier to port.
Ribbon created WIP ports for hundreds of emerging Rust programs in 2023,
and many are working with no modification.
Like mouse, keyboards, game controllers and other things.
## C/C++ Programs
## VirtIO Support
Ribbon also created WIP ports for classic and widely-used C/C++ programs and libraries, he focused to package the most used (and best) programs of the Linux/BSD world.
Anhad Singh from the [Aero](https://github.com/Andy-Python-Programmer/aero) project participated in our RSoC program from 2023 and implemented the VirtIO support on Redox.
Currently there are around 1,700 work-in-progress software ports, we need to write cross-compilation scripts and port/update some libraries to make them work.
He wrote some VirtIO drivers and improved the VirtIO GPU 2D acceleration to speed up our QEMU performance.
## First HTTP Web Server
You can read about his work on the following posts:
We ported our first HTTP web server, [Simple HTTP Server](https://github.com/TheWaWaR/simple-http-server), and served a website from Redox.
Thanks very much to contributor bpisch for his work on porting many difficult programs, and for this one in particular.

- [RSoC: virtio drivers - 2](https://www.redox-os.org/news/rsoc-virtio-2/)
## Notable Programs
## Build System Improvements
- Apache HTTP Server was ported and currently can serve a website on `localhost`
- RustPython was ported and is our first working Python interpreter implementation
- GNU Make was updated to a recent version
- The Lua interpreter was ported
- Perl 5 was ported
We would like to thank Ron Williams, bjorn3, Jeremy and 4lDO2 for their massive improvements to our build system configuration and tooling.
## Debugging Improvements
Ron Williams and Jeremy implemented new commands to ease the life of developers, packagers and testers.
The process to debug the recipes of Rust programs was implemented and the debugging documentation was improved.
It's possible to enable the Rust debug symbols and get the backtrace from the build system.
bjorn3 simplified our filesystem configuration system, reducing duplication and our maintenance cost.

- The scheme cancellation was implemented to allow the file descriptors to be closed
- New user-space schemes were introduced
- Many improvements to the scheme interface
### Networking
- The MAC addresses handling was improved
### Orbital

- More than 1700 programs and libraries were packaged (work-in-progress)
### Cookbook
- More recipes were converted to TOML
- All recipes were moved to categories
- ABI separation was added for some libraries
- Package policies were added to improve the quality of program packages
- A recipe for the Redox website was added
