Linux 7.1 adds Ryzen AI NPU power reporting

Linux 7.1 will add real-time power estimate reporting and column utilization tracking for AMD Ryzen AI NPUs via improvements to the AMDXDNA accelerator driver. The new ioctl interface exposes NPU power consumption data to user-space, helping developers measure energy efficiency across AI workloads on AMD hardware.

// ANALYSIS

Native NPU power visibility in the kernel is the missing piece for serious AI workload profiling on AMD Ryzen AI hardware — and Linux 7.1 finally closes that gap.

  • The new `DRM_IOCTL_AMDXDNA_GET_INFO` ioctl surfaces real-time power estimates by bridging the AMDXDNA driver with AMD's PMF platform driver — a clean kernel-layer solution versus vendor CLI tools
  • Column utilization reporting lets developers measure how busy the NPU actually is, enabling proper efficiency benchmarking across different LLM and AI inference workloads
  • This builds on GNOME Resources 1.10 (Feb 2026) adding NPU monitoring support, signaling a maturing ecosystem of observability tooling for AMD NPUs on Linux
  • AMD's `xrt-smi` CLI already offered some NPU metrics at the firmware layer; moving this into the kernel driver makes it universally accessible without vendor software stacks
  • Growing developer interest in running local LLM inference on NPUs makes power-per-token metrics increasingly critical — this addition arrives at the right time
