NAME top

       libpfm_arm_nvidia_olympus - support for NVIDIA Olympus core

SYNOPSIS top

       #include <perfmon/pfmlib.h>

       PMU name: arm_olympus
       PMU desc: NVIDIA Olympus Core PMU

DESCRIPTION top

       The library supports ARM Olympus core used in the NVIDIA Tegra410
       SoC.

       Olympus implements the Arm 9.2-A AArch64 instruction set with RAS,
       RME, MEC, SVE, SVE2, PMUv3, BRBE, ETE, TRBE, and SPE extensions.

       PMUv3 support includes FEAT_PMUv3p7, FEAT_PMUv3_EXT32, and
       FEAT_HPMN0.

       This PMU supports six 64-bit counters per processing element (PE)
       that can operate in both 32 and 64 bit modes.  Each Olympus core
       contains two logical PEs.

MODIFIERS top

       u      Measure at the user level. This corresponds to PFM_PLM3.
              This is a boolean modifier.

       k      Measure at the kernel level. This corresponds to PFM_PLM0.
              This is a boolean modifier.
