Greetings all;
Users of the RTAI facility to run certain processes on a cpu core that has been isolated by the boot parameter 'isolcpus=n' command need to be able to confirm that the process so launched is indeed using x% of that cpu core.
There doesn't appear to be any facility in such as htop, to actually determine this usage. In fact, if we taskset the whole linuxcnc (was emc till the lawyers wrote) gkrellm is the only utility that does show any usage of that isolated core. Then of course its quite high because every thread in the program is running on that core.
Is the monitoring of an isolcpus defined core even possible?
And if possible, could it be added to htop so it displays the core that the RTAI threads are running on?
It would sure give us another tool to help optimize this application.
Thanks and Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo. Please use in that order." -Ed Howdershelt (Author) My web page: <http://coyoteden.dyndns-free.com:85/gene> We totally deny the allegations, and we're trying to identify the allegators.
