Kernel Benchmarks

File: testbmk.c

Description

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.

Objective

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.

Preconditions

None.

Test Cases

• Messages performance #1
• Messages performance #2
• Messages performance #3
• Context Switch performance
• Threads performance, full cycle
• Threads performance, create/exit only
• Mass reschedule performance
• I/O Round-Robin voluntary reschedule.
• I/O Queues throughput
• Virtual Timers set/reset performance
• Semaphores wait/signal performance
• Mutexes lock/unlock performance
• RAM Footprint
