The misses/hit radio is the first number after "#".
For your case, 0.00% is the misses/hit radi
Inside the guest, I am using "perf stat -e dTLB-load-misses -e
dTLB-loads -e L1-dcache-loads -e L1-dcache-load-misses -e
L1-dcache-prefetch-misses ", followed by the parsec command.

Hi, Kan,
The dTLB-load-misses is 0, but it shows 80.00%hit, does that mean the
TLB-load miss is 0.8 * (dTLB-loads). Thanks.
Performance counter stats for './parsecmgmt -a run -i native -c
gcc-hooks -n 1 -p freqmine':
0 dTLB-load-misses #0.00% of all dTLB
cache hit
Hi, Kan,
Thanks for your reply.
1. If the guest is non-paravirt, can I get the LLC-loads number?
2. Do you know any method that can capture the LLC-loads for the guest? Thanks.

Hi, Kan,
Thanks for your reply.
1. If the guest is non-paravirt, can I get the LLC-loads number?
2. Do you know any method that can capture the LLC-loads for the guest?
Thanks.

Dear KVM developers:
I am trying use perf stat inside a VM to obtain some hardware cache
performance counter values.
The perf stat can report some numbers for L1 and TLB related counters. But

Dear KVM developers:
I am trying use perf stat inside a VM to obtain some hardware cache
performance counter values.
The perf stat can report some numbers for L1 and TLB related counters. But
for the LLC-loads and LLC-load-misses, the numbers are always 0. It seems
that the these offcore events are
