CPI calculations - this trace_mark is triggered triggered after X no. of clock cycles. The number of instructions executed and the no. of clock cycles is noted. 2. Cache Hit rate calculation - Here I have not used the PMC registers in the ARM processor - rather have used L2 Cache controller registers to find out this information - but this does not provide information about the L1 cache hit/miss behaviour. Any other suggestions on what else can be done in PMC? Also have ported LTTng to 2.6.24 for two Nomadik Boards - NDK15 and NDK20. Doing some tests and will send it over to you guys soon for your comments. Cheers! Have a Nice Day! Gaurav -------------- next part -------------- An HTML attachment was scrubbed... URL:
