Red Bear OS 8cd2f71ddd usbhubd: bound EP1 wait via worker thread + recv_timeout poll fallback
Root cause of hub-child enumeration stalling: after a synchronous
action (power-on, reset) the port's state changes WITHOUT a new
interrupt ever being generated, and the loop's next step was a blocking
EP1 transfer_read with no timeout — the daemon never woke to observe
the state it had just caused, so devices behind a hub sat
enabled-but-never-attached forever.

Move the blocking transfer_read onto a worker thread that forwards each
interrupt bitmap as a u64 mask over an mpsc channel. The main loop
waits with recv_timeout(POLL_FALLBACK_MS): a real bitmap processes only
the changed ports (interrupt fast path), while timeout/disconnect/error
falls back to an all-ports poll (progress guarantee). Matches the Linux
model where hub_irq is the accelerator but port status reads are always
authoritative.

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.
