This commit delivers a comprehensive set of updates including development
environment setup, advanced spinlock features, initial IPC robustness
KASSERTs, extensive Doxygen commenting, code formatting, and Doxygen setup.
Key Changes:
Part 0: Development Environment Setup
- Created `setup.sh` to automate installation of `doxygen`, `graphviz`,
`clang-format`, and `cppcheck`. (Tools were installed in the environment).
Part 1: Advanced Spinlock Features
- Enhanced `simple_spin_lock()` in `kernel/k_spinlock.h` with:
- Adaptive spinning: `MAX_SPIN_THRESHOLD` and a stubbed `kernel_yield()`
(calling `arch_pause()`).
- Contention statistics: `acquisitions` and `contentions` counters
added to `simple_spinlock_t` and integrated into lock functions.
- Added extensive Doxygen and inline comments for all spinlock code.
- Updated `docs/Signal_Refactoring_Verification.md` with these features.
Part 2: Initial IPC Robustness Analysis & KASSERTs
- Implemented an initial set of KASSERTs in `kernel/system.c` (in
`kernel_call`, `kernel_call_dispatch`, `kernel_call_finish`) for
validating IPC message parameters, call numbers, privileges, and
internal states.
- Added Doxygen/inline comments to these IPC functions.
- Created `docs/IPC_Robustness_Analysis.md` documenting these KASSERTs
and areas for further IPC validation.
Part 3: Code Formatting, Doxygen Setup & Review
- Code Formatting: Applied `clang-format --style=Google` to all C/H
files modified in recent KASSERT and spinlock work.
- Static Analysis: Ran `cppcheck`; no critical issues found in recent
changes requiring immediate code modification.
- Doxygen Setup: Created `docs/Doxyfile.kernel` with a comprehensive,
C23-aware configuration based on your feedback. This file enables
generation of extensive kernel documentation.
- `docs/Lock_Ordering.md`: Reviewed; no updates needed in this pass.
This work significantly improves kernel robustness, developer tooling,
code quality, and documentation infrastructure.
