## Self-Hosting Improvements
## FOSDEM 2025
Anhad Singh successfully compiled GNU Bash with dynamic linking, this is one part of the goals to allow more programs to work on Redox and dynamically link relibc to speed up the Redox development.
Jacob Lorentzon (4lDO2) will be presenting his work on Redox Signals in the Microkernels room February 1 at FOSDEM in Brussels. He will also do a short introductory presentation in the Kernel room on February 2.

## Dynamic Linking for Redox
Anhad Singh's Summer of Code project to implement dynamic linking on Redox continues with huge strides.
He successfully compiled GCC, GNU Binutils, GNU Make and GNU Bash with dynamic linking.
He also implemented dynamic linking support for the Redox triple on GCC.
Dynamic linking is an key part of our Stable ABI strategy, and will help us in our work towards self-hosted development.
Read his [report on the work so far](/news/01_rsoc2024_dynamic_linker).
## Kernel Improvements
- Andrey Turkin fixed a regression in the Raspberry Pi 3B support
- Zhouqi Jiang improved the [OpenSBI](https://github.com/riscv-software-src/opensbi) support for RISC-V
## Driver Improvements
- bjorn3 did many improvements and cleanup on video drivers
- bjorn3 did many refactorings on the graphics and input subsystems
- bjorn3 migrated all video drivers to the `redox-scheme` library
- bjorn3 created the `driver-graphics` library to unify code
- bjorn3 created the `graphics-ipc` library to unify code
- bjorn3 reduced the `fbcond` daemon and created the `fbbootlogd` daemon to fix boot deadlocks
- bjorn3 removed blocking on any graphics driver
- bjorn3 updated the `redox-scheme` library version
- bjorn3 fixed some warnings
- Andrey Turkin fixed the BCM2835 driver (Raspberry Pi 3 B+)
## VirtIO Improvements
- bjorn3 improved the VirtIO-GPU driver to allow Redox guest video size to follow the QEMU window size on the host system
- bjorn3 implemented window resizing support using VirtIO-GPU
Bjorn3 has been working on improvements to VirtIO-GPU.
He has improved the GPU driver to allow Redox guest video size to follow the QEMU window size on the host system,
including window resizing support.
He fixed a crash on the VirtIO-GPU driver when multiple displays are attached.
He also fixed a memory bug and improved the VirtIO-GPU driver performance.
Here is his [tracking issue for the work in progress](https://gitlab.redox-os.org/redox-os/redox/-/issues/1428).
## System Improvements
- bjorn3 migrated the remaining system components to the new scheme format

## Documentation Improvements
- The contributor rm-dr improved the RedoxFS code documentation
- Ribbon documented how to [download the relibc sources](https://gitlab.redox-os.org/redox-os/relibc#download-the-sources) and [build it](https://gitlab.redox-os.org/redox-os/relibc#build-instructions)
- Ribbon documented [how to mount a RedoxFS partition](https://gitlab.redox-os.org/redox-os/redoxfs#how-to-mount-a-partition)
- Jack Lin fixed broken links on the Cookbook README
## How To Test The Changes
To test the changes of this month download the `server` or `desktop` variants of the [daily images](https://static.redox-os.org/img/).
(Use the `server` variant for a terminal interface and the `desktop` variant for a graphical interface, if the `desktop` variant doesn't work use the `server` variant)
- If you want to test in a virtual machine use the "harddrive" images
- If you want to test on real hardware use the "livedisk" images
Sometimes the daily images are outdated and you need to build Redox from source, to know how to do this read the [Building Redox](https://doc.redox-os.org/book/podman-build.html) page.
