[PATCH v1 OLK-6.6 0/3] kworker: Fix the problem of ipsan performance degradation on ARM architecture
by jiangdongxu 28 Feb '24

28 Feb '24

From: shaodenghui <shaodenghui(a)huawei.com> When the current downstream FS tests IPSAN, it is found that the performance on ARM is much worse than that on X86, and the test data of IPSAN fluctuates greatly. After analysis, the reason is that when iscsi issues IO, the task is sent to kworker for processing by iscsi_xmitworker. The workqueue created by iscsi can automatically identify the CPU of the soft interrupt currently processed by iscsi, and automatically schedule the workqueue to the corresponding NUMA node. shaodenghui (3): iscsi: add member for NUMA aware order workqueue workqueue: implement NUMA affinity for single thread workqueue iscsi: use dynamic single thread workqueue to improve performance drivers/scsi/iscsi_tcp.c | 9 +++++++++ drivers/scsi/libiscsi.c | 17 ++++++++++++----- include/linux/workqueue.h | 1 + include/scsi/libiscsi.h | 1 + kernel/workqueue.c | 15 ++++++++++----- 5 files changed, 33 insertions(+), 10 deletions(-) -- 2.33.0
