Discovery backend structure.
A backend is the instantiation of a discovery component. When a component gets enabled for a topology, its instantiate() callback creates a backend.
hwloc_backend_alloc() initializes all fields to default values that the component may change (except "component" and "next") before enabling the backend with hwloc_backend_enable().
void(* hwloc_backend::disable)(struct hwloc_backend *backend) |
Callback for freeing the private_data. May be NULL.
int(* hwloc_backend::discover)(struct hwloc_backend *backend) |
Main discovery callback. returns > 0 if it modified the topology tree, -1 on error, 0 otherwise. May be NULL if type is HWLOC_DISC_COMPONENT_TYPE_MISC.
unsigned long hwloc_backend::flags |
Backend flags, as an OR'ed set of HWLOC_BACKEND_FLAG_*.
int(* hwloc_backend::get_obj_cpuset)(struct hwloc_backend *backend, struct hwloc_backend *caller, struct hwloc_obj *obj, hwloc_bitmap_t cpuset) |
Callback used by the PCI backend to retrieve the locality of a PCI object from the OS/cpu backend. May be NULL.
int hwloc_backend::is_custom |
Backend-specific 'is_custom' property. Shortcut on !strcmp(..->component->name, "custom"). Only the custom component should touch this.
int hwloc_backend::is_thissystem |
Backend-specific 'is_thissystem' property. Set to 0 or 1 if the backend should enforce the thissystem flag when it gets enabled. Set to -1 if the backend doesn't care (default).
int(* hwloc_backend::notify_new_object)(struct hwloc_backend *backend, struct hwloc_backend *caller, struct hwloc_obj *obj) |
Callback called by backends to notify this backend that a new object was added. returns > 0 if it modified the topology tree, 0 otherwise. May be NULL.
void* hwloc_backend::private_data |
Backend private data, or NULL if none.
