Linux 7.1 Will Bring Power Estimate Reporting For AMD Ryzen AI NPUs

The latest drm-misc-next patches include improvements to the AMDXDNA driver for Ryzen AI NPUs, set to be included in Linux 7.1. These updates introduce a new ioctl for reading real-time power estimates from the hardware and expose NPU column utilization metrics to user-space. This functionality allows users to monitor the power consumption and utilization of the NPU during AI workloads, which is particularly relevant with the recent release of LLM frameworks like Lemonade 100 and FastFlowLM. The power reporting is achieved through work with the AMD PMF platform driver, exposing data via DRM_IOCTL_AMDXDNA_GET_INFO.
