Userspace Documentation

This section documents Valecium userspace components by source directory. Each page below maps to a directory under usr/ and summarizes its purpose and role in runtime testing.

Userspace Components

libmath.ad — Minimal shared math library for userspace
sh.ad — Interactive shell userspace program
selftest.ad — Syscall-based userspace self-test program
test.ad — Legacy test directory (compatibility/transition)

Navigation Notes

Start with selftest.ad if you are validating syscall and context-switch behavior.
See kernel/syscall.ad for kernel-side syscall handling details.
For build integration, see building.ad and usr/SConscript.
