Hi all, I am a newbie to Intel forum. I hope this is the correct subforum to post this thread; if not, please forward it to the correct place. I am working on a project using hardware performance monitoring counters. In my current implementation, the counter values are read through a file under /proc (thus I need to create a proc_entry before the sampling and read the values to this file during execution), and the samplings are implemented by inserting a task into the delayed work queue. By doing this, I am able to read the performance counter values at fixed time intervals, say, once a second. However, I want to read the counters in another way. Namely, rather than collect those counters every second, I would like to read them after one million instructions are executed. That is, read the counter values when 1M, 2M, 3M....instructions are executed. I have no clue on this change. Can anyone give me a hint on this? Any suggestions will be appreciated. By the way, I am using Fedora 13 with kernel 2.6.33. Thanks
