Hi, I'd like to learn how to take better test data on the real-time kernel. I think that I've correctly correctly enabled everything that's called for on this page: lightning rt-tests # dmesg | grep Ingo Real-Time Preemption Support (C) 2004-2007 Ingo Molnar lightning rt-tests # lightning linux # cat .config | grep CONFIG_PREEMPT_RT CONFIG_PREEMPT_RT=y lightning linux # cat .config | grep CONFIG_WAKEUP_TIMING CONFIG_WAKEUP_TIMING=y lightning linux # cat .config | grep CONFIG_LATENCY_TRACE CONFIG_LATENCY_TRACE=y lightning linux # cat .config | grep CONFIG_CRITICAL_PREEMPT_TIMING CONFIG_CRITICAL_PREEMPT_TIMING=y lightning linux # cat .config | grep CONFIG_CRITICAL_IRQSOFF_TIMING CONFIG_CRITICAL_IRQSOFF_TIMING=y lightning linux # If I run cyclictest from the command like I get results like this with no load on the machine: lightning rt-tests # ./cyclictest -p 80 -t 5 -n -l 50000 1.46 0.67 0.43 5/115 6770 T: 0 ( 6744) P:80 I:1000 C: 50000 Min: 3 Act: 8 Avg: 6 Max: 25 T: 1 ( 6745) P:79 I:1500 C: 33340 Min: 3 Act: 7 Avg: 5 Max: 18 T: 2 ( 6746) P:78 I:2000 C: 25005 Min: 3 Act: 10 Avg: 5 Max: 14 T: 3 ( 6747) P:77 I:2500 C: 20004 Min: 3 Act: 10 Avg: 5 Max: 17 T: 4 ( 6748) P:76 I:3000 C: 16670 Min: 3 Act: 7 Avg: 4 Max: 14 lightning rt-tests # What now? How do I put a good load on the machine? I found source code for hackbench but no instructions for someone at my level to build it. I tried pi_stress but it hung my machine. Open to any simple ways to give better info.
