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

+Description: Read-only. This file always returns the cpu to which the
+ IDXD DSA pmu is bound for access to all dsa pmu
+ performance monitoring events.
