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.
