| Description:
 | |
| 		Attribute group to describe the magic bits that go into
 | |
| 		perf_event_attr::config[012] for a particular pmu.
 | |
| 		Each attribute of this group defines the 'hardware' bitmask
 | |
| 		we want to export, so that userspace can deal with sane
 | |
| 		name/value pairs.
 | |
| 
 | |
| 		Example: 'config1:1,6-10,44'
 | |
| 		Defines contents of attribute that occupies bits 1,6-10,44 of
 | |
| 		perf_event_attr::config1.
