0005 Description: Read-only. Attribute group to describe the magic bits
0006 that go into perf_event_attr.config or
0007 perf_event_attr.config1 for the IDXD DSA pmu. (See also
0008 ABI/testing/sysfs-bus-event_source-devices-format).

0010 Each attribute in this group defines a bit range in
0011 perf_event_attr.config or perf_event_attr.config1.
0012 All supported attributes are listed below (See the
0013 IDXD DSA Spec for possible attribute values)::
0014
0015 event_category = "config:0-3" - event category
0016 event = "config:4-31" - event ID
0017
0018 filter_wq = "config1:0-31" - workqueue filter
0019 filter_tc = "config1:32-39" - traffic class filter
0020 filter_pgsz = "config1:40-43" - page size filter
0021 filter_sz = "config1:44-51" - transfer size filter
0022 filter_eng = "config1:52-59" - engine filter
