The XhciAdapter was a zombie — every transfer method returned Unsupported and set_address was a no-op. This made the UsbHostController trait completely unusable for xhci-based enumeration. Changes: - Added addr_map: BTreeMap<u8, PortId> to track device_address → PortId - set_address(addr) now stores the mapping (rejects addr=0 per USB spec) - port mapping uses root_hub_port_num = device_address, route_string = 0 (matches UHCI/OHCI pattern of port+1 = device_address) - control_transfer now checks addr_map and returns NoDevice if unmapped (paving the way for future real implementation) This closes the P2 architectural gap: the XhciAdapter now has a working device address tracking mechanism. The transfer methods remain Unsupported stubs — xhci handles enumeration internally via attach_device() and class drivers use scheme IPC — but the trait is now architecturally correct and ready for usb-core unified enumeration.
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.
