Intel Platform Monitoring Technology (PMT) telemetry and crashlog
A telemetry and diagnostics framework Intel builds into modern CPUs, chipsets, FPGAs, and accelerators that exposes performance counters, power and thermal data, and post-mortem crash logs to the operating system. It's present on current client and server Intel platforms and is the in-kernel interface tools use to read live platform health data.
recommendation
It should stay because the hardware is current and shipping in 2025, Intel is still publishing PMT documentation and companion tools (including a VMware ESXi release in December 2024), and the kernel directory continues to receive active maintenance, including new hardware enablement such as Battlemage GPU crashlog support landing in late 2025. There is no alternative in-tree driver that exposes Intel's PMT discovery, telemetry, and crashlog surfaces.

- git.kernel.org
Mainline kernel history for this directory remains active, with substantive PMT fixes and feature work landing through late 2025 and treewide follow-up touches in early 2026.
- intel.com
Intel documents PMT as a current telemetry framework spanning CPU, PCH, FPGA, accelerators, and other Intel products; the spec page is current as of 2026-03-10.
- intel.com
Intel was still publishing PMT driver/tooling in December 2024 for VMware ESXi, showing ongoing productization rather than legacy-only support.
- github.com
Intel's PMT repository describes PMT as used across client, server, and companion products and explicitly states Linux mainline support exists under drivers/platform/x86/intel/pmt.
codex reasoning notes (technical)
Real driver directory confirmed locally via shell (`rg`, `find`, `sed`) with multiple module/auxiliary-driver entry points plus a KUnit test. Upstream activity was checked with local `git log` because `lei` was unavailable and no lore MCP endpoints were exposed; no removal/deprecation thread surfaced in web searches on lore, while local history showed late-2025 fixes and new hardware enablement (`support BMG crashlog`). `git.kernel.org` log URL is a canonical recall URL corresponding to that local history check. Intel PMT spec and ESXi download URLs were obtained with web search/open, and the Intel GitHub PMT repo URL was obtained with web open. Overall signal is active maintenance for still-current Intel platform telemetry hardware, with no natural replacement driver for the same in-kernel PMT discovery/telemetry/crashlog interface.
