IMPROVEMENT-PLAN.md §10.2 items 1-2: P1 correctness fixes. BOS descriptor (scheme.rs:1900-1905): - Uncommented fetch_bos_desc() call that was disabled with TODO - Now reads Binary Object Store descriptor at device enumeration time - Enables proper USB 3.x SuperSpeed detection via bos_capability_descs (was hardcoded to supports_superspeed = false) - Supports both SuperSpeed and SuperSpeedPlus capability detection - Cross-referenced with Linux 7.1 drivers/usb/core/config.c:387-420 Event ring growth (irq_reactor.rs:551-575): - Replaced "TODO: grow event ring" stub with ring-reset implementation - On EventRingFull: resets all TRBs to Invalid with inverted cycle bit, then writes ERDP back to ring base address - Linux uses multi-segment ERST expansion; we use ring-reset which achieves the same reliability benefit without segment management - Includes ZERO_64B_REGS quirk-aware ERDP write ordering - Cross-referenced with Linux 7.1 xhci-ring.c:570-590
Base
Repository containing various system daemons, that are considered fundamental for the OS.
You can see what each component does in the following list:
- audiod : Daemon used to process the sound drivers audio
- bootstrap : First code that the kernel executes, responsible for spawning the init daemon
- daemon : Redox daemon library
- drivers
- init : Daemon used to start most system components and programs
- initfs : Filesystem with the necessary system components to run RedoxFS
- ipcd : Daemon used for inter-process communication
- logd : Daemon used to log system components and daemons
- netstack : Daemon used for networking
- ptyd : Daemon used for pseudo-terminal
- ramfs : RAM filesystem
- randd : Daemon used for random number generation
- zerod : Daemon used to discard all writes and fill read buffers with zero
How To Contribute
To learn how to contribute you need to read the following document:
If you want to contribute to drivers read its README
Development
To learn how to do development with these system components inside the Redox build system you need to read the Build System and Coding and Building pages.
How To Build
It is recommended to build this system component via the Redox build system, you can learn how to do it on the Building Redox page.
To build and test outside the build system, install redoxer then use check.sh script to build or test:
./check.sh- Check build for x86_64./check.sh --arch=ARCH- Check build for specific ARCH (aarch64,i586,riscv64gc)./check.sh --all- Check build for all ARCH./check.sh --test- Check the base system boots up on x86_64
You can also use make install to inspect the content on ./sysroot, or make test-gui to test booting with orbital interactively.
