(Image credit: AMD) AMD has submitted Linux kernel patches including support for its new low-power CPU cores that will likely emerge in its future heterogeneous processors. The new patch clearly distinguishes between high-performance cores, efficiency cores, and low-power cores, so it is safe to say that AMD's upcoming CPU platforms will use three types of cores, with the low-power one serving light workloads, reports Phoronix . Go deeper with TH Premium: CPU AMD's heterogeneous processors identify CPU types using CPUID Function 0x80000026 (Extended CPU Topology), as EBX bits [31:28] carry the core classification. Up until recently, AMD only classified its cores as Performance and Efficiency, while the latest patch adds Low-Power cores. The patch enables Linux to distinguish between Performance, Efficiency, and Low-Power cores efficiently, and the latter are also correctly supported by AMD's performance management.…
