Linux kernel scheduling will optimize Zhaoxin CPU to improve program performance

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.

The above is the detailed content of Linux kernel scheduling will optimize Zhaoxin CPU to improve program performance. For more information, please follow other related articles on the PHP Chinese website!
