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 not exposed to the guest.
Is this a bug in Qemu or KVM? My testbed is Host kernel: 3.12.26 Qemu: 2.1.0 CPU: Intel Ivy bridge 2620 VM boosted by qemu, with -cpu host. Thanks. - Hui Kang -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
