+ * \brief Kernel context switch benchmark.
+ *
+ * This benchmark measures the overhead (in µs) required to deliver a
+ * signal and switch from a low-priority process to a high-priority process.
+ *
+ * The measure is made by the high-precision timer if supported by the
+ * architecture. Alternatively, the time can also be measured using an external
+ * oscilloscope connected to the board's status LED.
