| 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. |
