Detailed Description
RTPreemptEC クラス
This class is real-time ExecutionContext which utilizes RT-Prempt kernel. This ExecutionContext is a real-time ExecutionContext which utilizes real-time scheduler functionality of "RT-Preempt" Linux kernel (patched or originally embedded).
Give the following configurations in your rtc.conf to use this EC.
exec_cxt.periodic.type: RTPreemptEC exec_cxt.periodic.rate: 1000 exec_cxt.priority: 50 manager.modules.load_path: <path to RTPreemptRC.so> manager.modules.preload: RTPreemptEC.so
Since this functionality requires root authority, your RTC which uses this EC have to be executed as root.
The following RTPreemptEC specific options are available.
- exec_cxt.periodic.priority: (default: 49)
- exec_cxt.periodic.rtpreempt.priority: (default: 49)
Execution priority of threads from 1 (lowest) to 99 (highest)
See Linux sched_setscheduler(2). - exec_cxt.periodic.rtpreempt.sched_policy: (default: fifo)
Scheduling policy.
rr: round-robin, fifo: FIFO type scheduling (default: fifo)
See Linux sched_setscheduler(2). - exec_cxt.periodic.rtpreempt.wait_offset: (default: -10000)
Offset time of wait. It can be given [ns] unit.
Adjusting this value, If dozens micro seconds delay in one execution cycle constantly, more accurate periodic execution can be achieved.
NOTICE: When performing comparatively quick cycle (tens of ms or more) using this EC, log-level have to be lower than DEBUG (logger.log_level: NORMAL or etc.). Moreover, even if "logger.enable=No" is set, if "logger.log_level=PRANOID" is set, execution of onExecute() takes longer time and it may cause deadline-miss. So caution is needed.
