Hi,
I am using perfmon on Intel Core 2 Quad CPU Q6600 and trying to read event
counters for L2 cache, such as, L2_LINES_IN, L2_IFETCH etc. I found the names
of the events using pfm_get_event_name() function. But when I specify "L2_ST"
in the pfm_find_full_event() to initiate the counters, it shows the error
message:
"event invalid or missing unit mask".
How can I find the unit mask for an event? I have used the function
pfm_find_event_mask(), but it is still showing the error message "event
invalid".
Although the pfm_get_event_name() function tells that L2 caches events are
supported, are there any reasons why it is showing the error message?
Can you help?
Thanks
Tanima.
