- * @page test_benchmarks Kernel Benchmarks
- *
- * File: @ref testbmk.c
- *
- * <h2>Description</h2>
- * This module implements a series of system benchmarks. The benchmarks are
- * useful as a stress test and as a reference when comparing ChibiOS/RT
- * with similar systems.
- *
- * <h2>Objective</h2>
- * Objective of the test module is to provide a performance index for the
- * most critical system subsystems. The performance numbers allow to
- * discover performance regressions between successive ChibiOS/RT releases.
- *
- * <h2>Preconditions</h2>
- * None.
- *
- * <h2>Test Cases</h2>
