Zhaoxin Working on Linux Support for Preferred Core on Their CPUs
Zhaoxin engineers are developing preferred core support for their processors in the Linux kernel. Similar to Intel and AMD processors, Zhaoxin CPUs can have cores with different frequencies and maximum frequencies. The proposed Linux kernel patches will use existing ACPI functionality to indicate the per-core differences and will reflect that within the ACPI CPUFreq driver. This will allow the scheduler to prioritize running tasks on the preferred cores for improved performance.
