Test Suites

There are several test suites available:

• Linux Test Project
• rt-tests

Resource Partitioning

• CPU Partitioning

Latency detection

Information about latency debugging techniques is available here.

The following tools can be useful for latency detection:

• The realtime Linux analysis tool (RTLA)
• Cyclictest (part of the test suite rt-tests)
• Ftrace
• LTTng
• latency-tracker
• Ftrace - hwlat tracer
• Perf stat - Cost of SMI handling
• scheduler analysis with perf

The following projects use Cyclictest results to evaluate latencies:

• rteval
• Worst case latency test scenarios
