Hi all,
Seeking help for the following problem on using perfmon2 on Pentium4.
Thanks & regards
JK
Problems encountered while using two events together:
========================================================
******************************************************************************************************
The events mentioned first gets the count values while the next one remains
zero always as shown below
******************************************************************************************************
session output:
==============
[EMAIL PROTECTED]:~> pfmon -ePAGE_WALK_TYPE:DTMISS,PAGE_WALK_TYPE:ITMISS ls
/dev/null
/dev/null
967 PAGE_WALK_TYPE:DTMISS
0 PAGE_WALK_TYPE:ITMISS
[EMAIL PROTECTED]:~> pfmon -ePAGE_WALK_TYPE:ITMISS,PAGE_WALK_TYPE:DTMISS ls
/dev/null
/dev/null
917 PAGE_WALK_TYPE:ITMISS
0 PAGE_WALK_TYPE:DTMISS
************************************************
while both can be used together as shown below:
************************************************
[EMAIL PROTECTED]:~> pfmon --check-events-only
-ePAGE_WALK_TYPE:DTMISS,PAGE_WALK_TYPE:ITMISS
[EMAIL PROTECTED]:~> echo $?
0
Other example while doing sampling:
===================================
*********************************************************************************
1. Here the second event PAGE_WALK_TYPE:DTMISS remins zero throughout the
sampling:
