hi. am not getting hardware PMIs on kabini with 3.4 or 3.15 kernel. due to this, kernel based hard lockup detection is broken.
I see below code in tip of linux tree perf_event_amd_uncore.c
/* and we do not enable counter overflow interrupts */
hwc->config = event->attr.config & AMD64_RAW_EVENT_MASK_NB;
does it mean that h/w PMUs are supported differently for 16h family?
