STRUCT AMD_PMF_NPU_METRICS(9)

💅 struct amd_pmf_npu_metrics(9) 💅

Hey bestie 💖, welcome to the Kernel API Manual. This page is literally struct amd_pmf_npu_metrics(9), and its whole personality is: Get NPU metrics data from PMF driver. That's the plot, no cap. 🎀✨

✨ NAME ✨

struct amd_pmf_npu_metrics — Get NPU metrics data from PMF driver. It's giving “the NPU report card,” and honestly? Obsessed. 🫶

🛠️ SYNOPSIS 🛠️

       struct amd_pmf_npu_metrics {
           u16 npuclk_freq;
           u16 npu_busy[8];
           u16 npu_power;
           u16 mpnpuclk_freq;
           u16 npu_reads;
           u16 npu_writes;
           u16 npu_temp;
        };
