[PATCH openEuler-1.0-LTS 1/3] scsi: hisi_sas: Change DMA setup lock timeout to 2.5s
From: Xingui Yang <yangxingui@huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5BXH1 CVE: NA ------------------------------------------------------------------- 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.

From: Xingui Yang <yangxingui@huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5CG2F CVE: NA ----------------------------------------------------------------------- SATA_DISK_ERR bit is bit16 of cq dw3，when it is set to 1, it means this sata disk is in error status and IPTT is invalid, such as NCQ error. In this scenario, new IO issued from this disk will be rejected by sas controller, all I/O remained in disk should be aborted. To ensure sas controller wouldn't operate memory before abort all I/O, all I/O remained in the disk should be set to aborted state by register and completed with state SAS_ABORTED_TASK through task_done(), then SCSI error handling thread will be wake up immediately to analyze the cause of the error, such as read log page for error details.
