Package: manpages-dev Version: 3.05-1 I found that the manual page of getrlimit doesn't describe the unit of the amount of CPU time for RLIMIT_RTTIME.
| RLIMIT_RTTIME (Since Linux 2.6.25) | Specifies a limit on the amount of CPU time that a process | scheduled under a real-time scheduling policy may consume with- | out making a blocking system call. For the purpose of this | limit, each time a process makes a blocking system call, the | count of its consumed CPU time is reset to zero. The CPU time | count is not reset if the process continues trying to use the | CPU but is preempted, its time slice expires, or it calls | sched_yield(2). | | Upon reaching the soft limit, the process is sent a SIGXCPU sig- | nal. If the process catches or ignores this signal and contin- | ues consuming CPU time, then SIGXCPU will be generated once each | second until the hard limit is reached, at which point the pro- | cess is sent a SIGKILL signal. | | The intended use of this limit is to stop a runaway real-time | process from locking up the system. I guess the unit is micro seconds. http://lkml.org/lkml/2007/12/18/218 http://linux.derkeiler.com/Mailing-Lists/Kernel/2008-04/msg03922.html -- Tanaka Akira -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
