Hi all,
I saw the energy model related patches have been posted [1], so i'd like to ask some questions for the tool rt-app:
I downloaded rt-app from the address [2];
For the case "rt-app [4]: mp3 playback use-case model", is it the same one with doc/examples/mp3-long.json?
For the case "rt-app [4]: 5 ~[6,13,19,25,31,38,44,50]% periodic (2ms) tasks for 30s", i have not seen there have .json scripts for these cases; so could you help point where i can get related scripts?
i read the case doc/examples/tutorial/example3.json, its comments say "starts with a 10% load during 1sec (100 loops) and then increase 90% for the next sec (100 loops)".
it's confused me due i cannot calculate the same workload with the comment clarified. For the phase "light", it only specifies the flow as run 1ms + timer 30ms, so the workload only have 1/30 = 3.33%; for the phase "heavy", it will get workload = 4/30 = 13.33%;
Could you help confirm if i wrongly understand this case?
{ /* * Simple use case which starts with a 10% load during 1sec (100 loops) * and then increase to 90% for the next sec (100 loops) */ "tasks" : { "thread0" : { "instance" : 12, "loop" : 1, "phases" : { "light" : { "loop" : 10, "run" : 1000, "timer" : { "ref" : "unique", "period" : 30000 } }, "heavy" : { "loop" : 10, "run" : 4000, "timer" : { "ref" : "unique", "period" : 30000 } } } } }, "global" : { "logdir" : "./", "log_basename" : "rt-app3", "ftrace" : true, "gnuplot" : true } }
