总的来说,cpu_capacity是调度器用于衡量每个CPU核心的相对处理能力的重要指标,尤其是在现代异构多核系统中,它能够显著优化性能和功耗的平衡。 回到顶部 cpu_capacity_orig 在Linux内核中,cpu_capacity_orig是每个CPU在系统启动时的原始处理能力,它表示CPU在未进行任何动态调整之前的基线容量。 详细说明 与cpu_capacity...
capacity_scale= max(cpu_capacity, capacity_scale);//记录最大cpu capacity值作为scale,不能超过scale。因此cpu capacity都是大核1024,小核<1024raw_capacity[cpu] = cpu_capacity;//raw capacity就是dts中dmips值,其实就是调度中经常使用到的cpu_capacity_origpr_debug("cpu_capacity: %pOF cpu_capacity=%u ...

IBM publishes their Large Systems Performance Reference (LSPR) ratings, and Amdahl and HDS publish their relative perfirmance ratings for new processor speeds and capacity. Do these ratings match your workloads and will your work experimence the performance differences as published by the vendors?
