As far as I know pseries is the only platform that uses DR connectors, and I highly doubt that any other powerpc platform or arch ever will. So, I'm not sure that this is really generic enough to belong in topology.h. If anything I would suggest putting this in an include in arch/powerpc/include/ named something like drcinfo.h or pseries-drc.h. That will make it visible to modules like rpaphp that want/need to use this functionality. -Tyrel > > int arch_update_cpu_topology(void); > > +int arch_find_drc_match(struct device_node *dn, > + bool (*usercb)(struct device_node *dn, > + u32 drc_index, char *drc_name, > + char *drc_type, u32 drc_power_domain, > + void *data), > + char *opt_drc_type, char *opt_drc_name, > + bool match_drc_index, bool ck_php_type, > + void *data); > + > /* Conform to ACPI 2.0 SLIT distance definitions */ > #define LOCAL_DISTANCE 10 > #define REMOTE_DISTANCE 20 >
