20 and stores are sampled. Use the -t option to limit to loads or stores.
22 Note that on Intel systems the memory latency reported is the use-latency,
26 On Arm64 this uses SPE to sample load and store operations, therefore hardware
27 and kernel support is required. See linkperf:perf-arm-spe[1] for a setup guide.
