Xiang Chen 4fefe5bbf5 scsi: hisi_sas: Use pci_irq_get_affinity() for v3 hw as experimental ... For auto-control irq affinity mode, choose the dq to deliver IO according to the current CPU. Then it decreases the performance regression that fio and CQ interrupts are processed on different node. For user control irq affinity mode, keep it as before. To realize it, also need to distinguish the usage of dq lock and sas_dev lock. We mark as experimental due to ongoing discussion on managed MSI IRQ during hotplug: https://marc.info/?l=linux-scsi&m=154876335707751&w=2 We're almost at the point where we can expose multiple queues to the upper layer for SCSI MQ, but we need to sort out the per-HBA tags performance issue.
