RIO_GET_ASM(9) RapidIO driver interface RIO_GET_ASM(9)
NAME
rio_get_asm - Begin or continue searching for a RIO device by vid/did/asm_vid/asm_did
SYNOPSIS
struct rio_dev * rio_get_asm(u16 vid, u16 did, u16 asm_vid, u16 asm_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
asm_vid
RIO asm_vid to match or RIO_ANY_ID to match all asm_vids
asm_did
RIO asm_did to match or RIO_ANY_ID to match all asm_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, did, asm_vid, asm_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.
