Intel’s Platform Monitoring Technology (PMT) Gains Expanded Linux Support
The upcoming Linux 6.16 kernel introduces critical updates for Intel’s Platform Monitoring Technology (PMT), enhancing power and performance telemetry capabilities for next-gen Lunar Lake and Panther Lake SoCs.
This development ensures deeper hardware insights for developers, IT administrators, and performance-tuning professionals.
With PMC SSRAM telemetry driver integration, Linux users gain structured access to Intel PMT telemetry regions, enabling real-time monitoring via sysfs and the Intel PMT API.
This update underscores Intel’s commitment to open-source hardware telemetry, benefiting enterprise and high-performance computing environments.
Key Developments in Linux 6.16 for Intel PMT
1. PMC SSRAM Telemetry Driver Now Supports Lunar Lake & Panther Lake
Originally, the PMC (Power Management Controller) driver was split to include a dedicated SSRAM Telemetry driver, designed to:
Register telemetry regions for system monitoring
Expose PMC data via sysfs and Intel’s PMT API
Optimize performance tracking for Intel CPUs, SoCs, and GPUs
However, Lunar Lake and Panther Lake device IDs were initially missing—a critical oversight now rectified in Linux 6.16.
2. Additional x86 Platform Driver Updates
This week’s x86 platform-drivers pull request also includes:
Samsung Galaxybook driver support (Notebook 9 Pro & other models)
Lenovo Ideapad optimizations (reduced embedded controller polling frequency)
Various stability fixes ahead of Linux 6.16-rc3
These refinements ensure better power efficiency, stability, and hardware compatibility across Intel-powered devices.
