Hi,
I need to read the values for the counter to count L2 cache misses. I have
tried pfm_find_full_event(). But this function only takes the
string specifying the name of the event and the event identifier but
takes no parameter for the unit mask. There are some other functions, such as,
pfm_get_event_mask_name or pfm_get_event_mask_description. But I cannot use
these to read the counters calues. Which interface should I use to specify the
unit mask to read the particular counter value? For example, for L2 cache
misses the event is L2_LINES_IN has four masks.The values of the unit maska
are: 0 for this core, 1 for both cores, 2 for all inclusive and 3 fr hardware
prefetch only. How can I specify which unit mask I need to consider?
Thanks,
Tanima
