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.
Userspace must be prepared for the possibility that attributes
define overlapping bit ranges. For example:
attr1 = 'config:0-23'
attr2 = 'config:0-7'
attr3 = 'config:12-35'
Example: 'config1:1,6-10,44'
Defines contents of attribute that occupies bits 1,6-10,44 of
perf_event_attr::config1.
