RIO_GET_DEVICE(9)					     RapidIO driver interface						 RIO_GET_DEVICE(9)

rio_get_device - Begin or continue searching for a RIO device by vid/did SYNOPSIS
struct rio_dev * rio_get_device(u16 vid, u16 did, struct rio_dev * from); ARGUMENTS
vid RIO vid to match or RIO_ANY_ID to match all vids did RIO did to match or RIO_ANY_ID to match all dids from Previous RIO device found in search, or NULL for new search DESCRIPTION
Iterates through the list of known RIO devices. If a RIO device is found with a matching vid and did, the reference count to the device is incrememted and a pointer to its device structure is returned. Otherwise, NULL is returned. A new search is initiated by passing NULL to the from argument. Otherwise, if from is not NULL, searches continue from next device on the global list. The reference count for from is always decremented if it is not NULL. AUTHOR

scsi_get_device_type_string - look up per-device-type, returning matching information string SYNOPSIS
#include <sys/scsi/scsi.h> char *scsi_get_device_type_string(char *prop_name, dev_info_t *dip, struct scsi_device *devp); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
prop_name Name of string array property that contains a list of paired device-type information. dip Pointer to the device info node for this HBA driver. devp Pointer to a scsi_device(9S) structure of the target. DESCRIPTION
The scsi_get_device_type_string() function looks up the prop_name property, which can be specified in the HBA's driver.conf(4)file. This property allows specification of per-device-type information. The syntax for prop_name in a driver.conf(4) file is: The formal syntax is: prop_name = <duplet> [, <duplet> *]; where: <duplet> := "<vid+pid>", "<information" The string <vid+pid> is returned by the device on a SCSI inquiry command. This string can contain any character in the range 0x20-0x7e. Characters such as double quote (") or single quote ('), which are not permitted in property value strings, are represented by their octal equivalent (for example, 42 and 47). Trailing spaces can be truncated. For example: scsi_vhci_failover_override = "STK FLEXLINE 400", "f_asym_lsi", "SUN T4", "f_tpgs";; The scsi_get_device_type_string() function searches the list of duplets for a matching INQUIRY string. If a match is found, scsi_get_device_type_string returns a copy of the <information> string. The meaning of the returned <information> string is determined by the caller. RETURN VALUES
scsi_get_device_type_string() returns a copy of the matching <information> string, or if no match is found, NULL is returned. When a non- NULL value is returned, the caller is responsible for freeing the <information> string via: kmem_free(info, strlen(info) + 1); CONTEXT
This function can be called from kernel or interrupt context. SEE ALSO
