when i use ddi_prop_op to give wwn property of device ,there has a coredump .
there maybe some bug in the ddi_prop_search_common which is called by
ddi_prop_op ,
if property not exist in devi_drv_prop_ptr and evi_sys_prop_ptr is null
code is follow :
propp = i_ddi_prop_search(dev, name, flags,
&(DEVI(dip)->devi_drv_prop_ptr));
if (propp == NULL) {
propp = i_ddi_prop_search(dev, name, flags,
&(DEVI(dip)->devi_sys_prop_ptr));
}
if ((propp == NULL) && DEVI(dip)->devi_global_prop_list) {
propp = i_ddi_prop_search(dev, name, flags,
&DEVI(dip)->devi_global_prop_list->prop_list);
}
if (propp == NULL) {
propp = i_ddi_prop_search(dev, name, flags,
&(DEVI(dip)->devi_hw_prop_ptr));
}
Mabey there is some sequence required ,call you tell me how to get the wwn
property of device
thanks
