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

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
