Petersen <martin.petersen@oracle.com> diff a090fc97 Sun May 14 20:41:20 MDT 2023 Xingui Yang <yangxingui@huawei.com> scsi: hisi_sas: Change DMA setup lock timeout to 2.5s DMA setup lock timeout protection is added when DMA setup frames are received. It's a function outside the protocol and used to prevent SATA disk I/Os from being delivered for a long time. The default value is 100ms, it's too strict and easily triggered timeout when the disk is overloaded or faulty. Based on the average I/O latency of 300 disks, we adjust the value to 2.5s.

For SAS HBAs of 920B and later version, those HW registers are set through firmware. And different HBA models are distinguished through pci_dev->revision.
