Re: Keeping track of the CPU time for a thread

I want to measure how much CPU time a thread has consumed. When the CPU time consumption exceeds a certain limit (specific to that thread), I want to raise an interrupt. Please suggest me how can I do it efficiently?

The L4::Thread interface has the stats_time function to get the consumed time of a thread (FINE_GRAINED_CPUTIME in the kernel might be of interest here). Triggering an interrupt goes with its trigger function. Then it's just about plugging this together. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
