Subject: [PATCH 0/6] perf jevents: Add NVIDIA Tegra410 uncore PMU events and metrics
Date: Mon, 19 Oct 2026 16:42:35 +0000 [thread overview]
Message-ID: <20261019164241.403644-1-bwicaksono@nvidia.com> (raw)
Add event aliases and derived metrics for the NVIDIA Tegra410 uncore
PMUs.
The series covers the UCF, PCIe, PCIe target, CPU memory latency, and
chip-to-chip interconnect PMUs. It provides symbolic names for the raw
event encodings and metrics for bandwidth, frequency, and average read
latency.
Patch 1 fixes a jevents ordering problem found with this layout: the
uncore events live in arch/arm64/nvidia/t410/sys/, next to the T410 core
events, and without the fix jevents puts the core tlb.json (which sorts
after "sys") into the sys table, so its events are lost from perf list
and perf stat.
