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.

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.

1.0.1
