[PATCH OLK-5.10 v7 00/11] Memory access profiler(SPE) driven NUMA balancing
by Ze Zuo 04 Jun '24

04 Jun '24

Hi, In Arm processors, there is a hardware PMU (Performance Monitoring Unit) facility called Statistical Profiling Extension (SPE) that can gather memory access metrics. In this patchset, SPE is exploited as an access information sampling approach to drive NUMA balancing. This sampling approach is introducedto replace the method based on address space scanning and hint faults with the access information provided by the hardware. With this, it is no longer necessary for NUMA balancing to scan over the address space periodically and rely on task-to-page association built by NUMA hint faults. Instead, the access samples obtained from hardware PMU are fed to NUMA balancing as equivalents to page fault. Except for the replaced sampling approach, the rest of the NUMA balancing policy is retained to do pages and tasks migrations according to the samples. Profiling based on SPE is an valid alternative sampling approach in NUMA balancing for the optimal page and task placement. This can be also extended to other architectures as long as there is a hardware PMU that supports memory access profiling. An abstract layer mem_sampling is introduced to reserve support for other kernel features and different types of hardware PMU. To help evaluate performance of this approach in system, syctl interfaces are added to enable/disable hardware mem sampling. NUMA balancing sampling approach can be also switched back to hint-faults- based approach dynamically. TODOs Currently, SPE for NUMA balance does not support PMD-level page migration, but it will be supported in later version. Changes since v6: -- clean code on spe.c, arm_spe_pmu.c. Changes since v5: -- Modify perf and mem_sampling compatibility logic. -- Introduce cmdline mem_sampling_on to use mem_sampling. Changes since v4: -- some patch check warning fixs, no functional change. Changes since v3: -- some clean code, no functional change. Changes since v2: -- clean code and commit fixs, no functional change. Changes since v1: -- clean code, no functional change.
