Intel Working On pmtctl Tool For Linux In Dealing With Platform Telemetry Data<\/a><\/p>\n

A set if 17 patches were posted today to the Linux kernel mailing list for introducing a new tool in the kernel source tree, pmtctl<\/strong>. This new pmtctl tool is for interfacing with Intel Platform Monitoring Technology.<\/p>\n

Intel’s Platform Monitoring Technology (PMT) is already supported by the mainline Linux kernel while pmtctl is a new convenient tool for dealing with these telemetry metrics. Like Turbostat and various other small utilities, Intel is aiming to have pmtctl live within the Linux kernel source tree.
\n<\/p>\n

\"pmtctl\"\/<\/p>\n

Intel engineer David Box explained of the new pmtctl tool:
\n
“Intel Platform Monitoring Technology (PMT) exposes per-component telemetry counters through sysfs via the pmt_telemetry auxiliary bus driver. Each telemetry device provides a data file that can be read to sample the underlying hardware telemetry data. The meaning of each field within a sample is described by platform-specific metric definitions.<\/p>\n

This series adds pmtctl, a command-line tool for querying PMT metrics on x86 Linux systems. It lives under tools\/arch\/x86\/pmtctl\/ alongside other platform-specific userspace tools.\n<\/p>\n

The series introduces approximately 7k lines across the library, CLI frontend, code generation scripts, and documentation.
\n
…
\n
The implementation is split into a reusable library (libpmtctl_core) and a thin CLI frontend:\n<\/p>\n

libpmtctl_core (lib\/)
\n
– Device enumeration: scans \/sys\/bus\/auxiliary\/drivers\/pmt_telemetry and reads GUID and telem data path from sysfs attributes.
\n
– Metric definitions: supports two loading modes:
\n
built-in — a C struct array compiled in at build time, generated from perf-style JSON by scripts\/gen_builtin_defs.py.
\n
runtime — loaded at invocation via -J\/–json-file (requires libjansson).
\n
– Metric DB: block-based container with flat-index accessors.
\n
– GUID intern table: canonical struct pmt_guid pointers shared between the built-in and JSON providers.\n<\/p>\n

CLI frontend (src\/)
\n
– list: enumerate discovered PMT devices and\/or metric definitions, with optional GUID…<\/p>\n
