Hi, I was able to run latency and switchbench tests on MPC860 board with IPIPE tracer feature enabled/disabled. Interrupt & scheduling Latencies and switching latencies (with IPIPE tracer option disabled) were having lower values when compared to latency values with IPIPE tracer enabled. cyclictest test results were same with or without IPIPE tracer enabled. Is this reduced context switching latency in switchbench test due to timer interrupt?
