| 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 |
