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.
