ahci_init_one-->ahci_host_activate-->ata_host_register-->ata_scsi_add_hosts -->scsi_host_alloc和scsi_add_host_with_dma 这里用到了两个scsi子系统重要的对外接入函数。 (2) target 在scsi内部针对每个target创建了一个名字为“targetk:m:n”的device结构体,其中k是host编号,m是channel编号,n是id编...

这里会通过MMIO写REG_UTP_TRANSFER_REQ_DOOR_BELL寄存器,将偏移(task_tag)告知UFS host controller。同时也表示通知UFS host controller此时可以通过已知的DMA地址访问对应的UTRD。 但是我们看到这里只传入了偏移task_tag,没有提供基地址,那UFS host controller内部的DMA控制器怎么知道该访问哪里呢?实际上,lrbp->utr_...

DSM_NOTIFICATION_REQUEST_BLOCK结构紧跟 SRB 的数据缓冲区中的SRB_IO_CONTROL结构。DSM_NOTIFICATION_REQUEST_BLOCK在 ntddscsi.h 中定义如下。 typedef struct _DSM_NOTIFICATION_REQUEST_BLOCK { ULONG Version; ULONG Size; ULONG NotifyFLags; ULONG DataSetProfile; ULONG Reserved[3]; ULONG DataSetRangesCount;...

SCSI_VERIFIER_DETECTED_VIOLATION 错误检查的值为 0x000000F1。 这是所有驱动程序验证程序 SCSI 验证违规的错误检查代码。
The SCSI_DISK_DRIVER_INTERNAL bug check has a value of 0x0000002D.This bug check appears very infrequently.
The HBA driver provides resource allocation, DMA management, and transport services in response to requests made by SCSI target drivers through SCSA. The host adapter driver also manages the host adapter hardware and the SCSI protocols necessary to perform the commands. When a command has been ...
