Field Documentation

◆ Cdb

VOID* EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::Cdb

A pointer to buffer that contains the Command Data Block to send to the SCSI device.

Definition at line 88 of file ScsiPassThru.h.

◆ CdbLength

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::CdbLength

The length, in bytes, of the buffer Cdb. The standard values are 6, 10, 12, and 16, but other values are possible if a variable length CDB is used.

Definition at line 98 of file ScsiPassThru.h.

◆ DataBuffer

VOID* EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::DataBuffer

A pointer to the data buffer to transfer between the SCSI controller and the SCSI device. Must be aligned to the boundary specified in the IoAlign field of the EFI_SCSI_PASS_THRU_MODE structure.

Definition at line 78 of file ScsiPassThru.h.

◆ DataDirection

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::DataDirection

The direction of the data transfer. 0 for reads, 1 for writes. A value of 2 is Reserved for Bi-Directional SCSI commands.

Definition at line 103 of file ScsiPassThru.h.

◆ HostAdapterStatus

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::HostAdapterStatus

The status of the SCSI Host Controller that produces the SCSI bus where the SCSI device attached when the SCSI Request Packet was executed on the SCSI Controller.

Definition at line 109 of file ScsiPassThru.h.

◆ SenseData

VOID* EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::SenseData

A pointer to the sense data that was generated by the execution of the SCSI Request Packet.

Definition at line 83 of file ScsiPassThru.h.

◆ SenseDataLength

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::SenseDataLength

On input, the length in bytes of the SenseData buffer. On output, the number of bytes written to the SenseData buffer.

Definition at line 119 of file ScsiPassThru.h.

◆ TargetStatus

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::TargetStatus

The status returned by the SCSI device when the SCSI Request Packet was executed.

Definition at line 114 of file ScsiPassThru.h.

◆ Timeout

UINT64 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::Timeout

The timeout, in 100 ns units, to use for the execution of this SCSI Request Packet. A Timeout value of 0 means that this function will wait indefinitely for the SCSI Request Packet to execute. If Timeout is greater than zero, then this function will return EFI_TIMEOUT if the time required to execute the SCSI Request Packet is greater than Timeout.

Definition at line 71 of file ScsiPassThru.h.

◆ TransferLength

UINT32 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::TransferLength

On Input, the size, in bytes, of InDataBuffer. On output, the number of bytes transferred between the SCSI controller and the SCSI device.

Definition at line 93 of file ScsiPassThru.h.
