According to news from this website on December 29, both Intel and AMD processors have a feature called Preferred Core, which will automatically prioritize work and assign it to high-performance cores to improve the efficiency of work processing. .

Recently, Zhaoxin engineers are also working hard to introduce preferred kernel scheduling support into Linux . With the proposed Linux kernel patch, Zhaoxin CPUs can use existing ACPI functionality to indicate per-core differences, and the patch will reflect this in the ACPI CPUFreq driver. This way, the scheduler can prioritize running tasks on the preferred core for better performance.

# However, the patch does not detail which Zhaoxin processors will support the preferred core. This site previously reported that the company has just launched a new generation of Kaixian KX-7000 series this month, which adopts a new "century道" independent core micro-architecture and integrates 8 high-performance cores with a maximum frequency of up to 3.7GHz.
