Help:why bus resource shortage?

[hongz at promisechina.com]

Hi guys:

 

I failed to get the pci bus resource after the driver is loaded (sc->r_mem
is NULL after bus_alloc_resource_any is called). Is it because bus resources
have been consumed by other drivers? Or other something happened? Please
help me on this!

 

Thanks!

Notes:

/* get resources */

rid = 0x10;

sc->r_mem = bus_alloc_resource_any(sc->dev, SYS_RES_MEMORY, &rid,
RF_ACTIVE);

if (!sc->r_mem) return ENOMEM;

 

The pci resources on our cards:
