Hi All
I get same values for the two events (i.e. LAST_LEVEL_CACHE_MISSES and
L2_LINES_IN:SELF) in user mode while the two change when the same are collected
for kernel+user mode. E.g.
pfmon -u -eLAST_LEVEL_CACHE_MISSES,L2_LINES_IN:SELF /bin/ls
cpu_2006_mix_lim_random_order_pfmon_t.sh
pair_lim_cpu_2006_pfmon_Phasewise_improved.sh pair_lim_cpu_2006_pfmon_t.sh
cpu_2006_pfmon_t.sh
pair_lim_cpu_2006_pfmon_Phasewise_prefetch.sh pair_lim_cpu_2006_pfmon_t.sh_old
827 LAST_LEVEL_CACHE_MISSES
827 L2_LINES_IN:SELF
pfmon -k -u -eLAST_LEVEL_CACHE_MISSES,L2_LINES_IN:SELF /bin/ls
cpu_2006_mix_lim_random_order_pfmon_t.sh
pair_lim_cpu_2006_pfmon_Phasewise_improved.sh pair_lim_cpu_2006_pfmon_t.sh
cpu_2006_pfmon_t.sh
pair_lim_cpu_2006_pfmon_Phasewise_prefetch.sh pair_lim_cpu_2006_pfmon_t.sh_old
1808 LAST_LEVEL_CACHE_MISSES
2267 L2_LINES_IN:SELF
Explanation for this is welcomed.
I also request people with latest release installed to check it.
Thanks and regards,
JK
