Detailed Description

Discovery component structure.

This is the major kind of components, taking care of the discovery. They are registered by generic components, either statically-built or as plugins.


Field Documentation

Enabled by default. If unset, if will be disabled unless explicitly requested.

Component types to exclude, as an OR'ed set of hwloc_disc_component_type_e.

For a GLOBAL component, this usually includes all other types (~0).

Other components only exclude types that may bring conflicting topology information. MISC components should likely not be excluded since they usually bring non-primary additional information.

struct hwloc_backend*(* hwloc_disc_component::instantiate)(struct hwloc_disc_component *component, const void *data1, const void *data2, const void *data3) [read]

Instantiate callback to create a backend from the component. Parameters data1, data2, data3 are NULL except for components that have special enabling routines such as hwloc_topology_set_xml().

Name. If this component is built as a plugin, this name does not have to match the plugin filename.

Component priority. Used to sort topology->components, higher priority first. Also used to decide between two components with the same name.

Usual values are 50 for native OS (or platform) components, 45 for x86, 40 for no-OS fallback, 30 for global components (xml, synthetic), 20 for pci, 10 for other misc components (opencl etc.).

Discovery component type.
