5	Description:
6			Attribute group to describe the magic bits that go into
7			perf_event_attr::config[012] for a particular pmu.
8			Each attribute of this group defines the 'hardware' bitmask
9			we want to export, so that userspace can deal with sane
10			name/value pairs.
11	
12			Userspace must be prepared for the possibility that attributes
13			define overlapping bit ranges. For example:
14				attr1 = 'config:0-23'
15				attr2 = 'config:0-7'
16				attr3 = 'config:12-35'
17	
18			Example: 'config1:1,6-10,44'
19			Defines contents of attribute that occupies bits 1,6-10,44 of
20			perf_event_attr::config1.
