A Linux scheduling fix addresses a slowdown affecting cache-intensive Clang builds on AMD’s Ryzen AI 9 HX 370, Phoronix reports. The issue arose when cache-aware scheduling placed work on the processor’s smaller, slower cores.
Why it mattersThe fix lets scheduling favour a higher-performing idle core over keeping tasks together in one cache group. A modest kernel adjustment, perhaps, but a useful reminder that processor performance depends on where Linux sends the work.
Discuss: When a scheduler must choose, should it favour faster cores or keeping related work close together in cache?
