 5Description:	Read-only.  Attribute group to describe the magic bits
 6		that go into perf_event_attr.config or
 7		perf_event_attr.config1 for the IDXD DSA pmu.  (See also
 8		ABI/testing/sysfs-bus-event_source-devices-format).
 9
10		Each attribute in this group defines a bit range in
11		perf_event_attr.config or perf_event_attr.config1.
12		All supported attributes are listed below (See the
13		IDXD DSA Spec for possible attribute values)::
14
15		    event_category = "config:0-3"    - event category
16		    event          = "config:4-31"   - event ID
17
18		    filter_wq      = "config1:0-31"  - workqueue filter
19		    filter_tc      = "config1:32-39" - traffic class filter
20		    filter_pgsz    = "config1:40-43" - page size filter
21		    filter_sz      = "config1:44-51" - transfer size filter
22		    filter_eng     = "config1:52-59" - engine filter
