H A D | spinlock_types.h | 5f1e001b Wed Oct 12 03:36:14 CDT 2022 Huacai Chen <chenhuacai@loongson.cn> LoongArch: Add qspinlock support
On NUMA system, the performance of qspinlock is better than generic spinlock. Below is the UnixBench test results on a 8 nodes (4 cores per node, 32 cores in total) machine.
A. With generic spinlock:
