NAME

pdc_get_initiator - Get the SCSI Interface Card params (SCSI ID, SDTR, SE or LVD)

SYNOPSIS

"SYNOPSIS"

int pdc_get_initiator (struct hardware_path * hwpath, unsigned char * scsi_id, unsigned long * period, char * width, char * mode);

ARGUMENTS

hwpath: fully bc.mod style path to the device.
scsi_id: what someone told firmware the ID should be.
period: time in cycles
width: 8 or 16-bit wide bus
mode: 0,1,2 -> SE,HVD,LVD signalling mode

DESCRIPTION

Get the SCSI operational parameters from PDC. Needed since HPUX never used BIOS or symbios card NVRAM. Most ncr/sym cards won't have an entry and just use whatever capabilities of the card are (eg Ultra, LVD). But there are several cases where it's useful: o set SCSI id for Multi-initiator clusters, o cable too long (ie SE scsi 10Mhz won't support 6m length), o bus width exported is less than what the interface chip supports.
