METRICS
Runtime (RDTSC) [s] time
Runtime unhalted [s] FIXC1*inverseClock
Clock [MHz] 1.E-06*(FIXC1/FIXC2)/inverseClock
CPI FIXC1/FIXC0
Number of stalls PMC1
Avg. stall duration [cyc] PMC0/PMC1
Stall ratio PMC0/FIXC1
LONG
Formulas:
Number of stalls = UOPS_RETIRED_STALLS
Avg. stall duration [cyc] = UOPS_RETIRED_STALLED_CYCLES/UOPS_RETIRED_STALLS
Stall ratio = UOPS_RETIRED_STALLED_CYCLES/CPU_CLK_UNHALTED_CORE

This group measures stalls in the UOP retirement.
