Hi all,

I wrote the rtl_sysload module (see attachment) that gives processor
load spent 
in each Real-Time thread and the remaining CPU load available for Linux. 

These statistics are displayed into the proc file system
/proc/rtlinux/sysload.

The rtl_sysload module reuses tracer events. So, you don't have to patch
RTLinux. 
You just have to enable the CONFIG_RTL_TRACER option in RTLinux and
recompile it.

I hope this tool will help you.

Greetings,

Joel.
