pciLocalToPciAdrs (replaced with sysLocalToBusAdrs)

Synopsis.

int pciLocalToPciAdrs ( int adrsSpace, char *localAdrs, char **busAdrs, int busId) adrsSpace - specifies which PCI address space. Must be one of the following defined constants:

PCI_MEMORY_SPACE (1) or PCI_IO_SPACE (2).

localAdrs - local address to convert.

busAdrs - where the converted address is returned.

busId - This parameter is not used.

Say the application code allocates a buffer in the PPC440 DRAM. In order for other PCI masters to access this buffer, the buffer's PCI address must be obtained from its corresponding local address.

Description.

Returns.

Example.

OK

, or

ERROR

.

char *localAdrs, *busAdrs;

/* Allocate a 1KB buffer in MPC8240 DRAM */ localAdrs = malloc (1024); if (localAdrs == NULL)

return (ERROR);

/* Find PCI address of buffer */ if (pciLocalToPciAdrs (PCI_MEMORY_SPACE, localAdrs, &busAdrs, 0) == ERROR)

return (ERROR); printf ("buffer local addr=0x%x, buffer PCI

bus address=0x%x\n", localAdrs, busAdrs);
