Definition at line 1536 of file scsi_transport_spi.c.

void spi_display_xfer_agreement ( struct scsi_target * starget )

spi_display_xfer_agreement - Print the current target transfer agreement : The target for which to display the agreement

Each SPI port is required to maintain a transfer agreement for each other port on the bus. This function prints a one-line summary of the current agreement; more detailed information is available in sysfs.

Definition at line 1118 of file scsi_transport_spi.c.

void spi_dv_device ( struct scsi_device * sdev )

spi_dv_device - Do Domain Validation on the device : scsi device to validate

Performs the domain validation on the given device in the current execution thread. Since DV operations may sleep, the current thread must have user context. Also no SCSI related locks that would deadlock I/O issued by the DV may be held.

void spi_schedule_dv_device ( struct scsi_device * sdev )

spi_schedule_dv_device - schedule domain validation to occur on the device : The device to validate

Identical to spi_dv_device() above, except that the DV will be scheduled to occur in a workqueue later. All memory allocations are atomic, so may be called from any context including those holding SCSI locks.
