| Description: Read-only. Attribute group to describe the magic bits |
| that go into perf_event_attr.config for a particular pmu. |
| (See ABI/testing/sysfs-bus-event_source-devices-format). |
| |
| Each attribute under this group defines a bit range of the |
| perf_event_attr.config. All supported attributes are listed |
| below. |
| |
| event = "config:0-11" - event ID |
| evtype = "config:12-15" - event type |
| portid = "config:16-23" - event source |
| |
| For example, |
| |
| fab_mmio_read = "event=0x06,evtype=0x02,portid=0xff" |
| |
| It shows this fab_mmio_read is a fabric type (0x02) event with |
| 0x06 local event id for overall monitoring (portid=0xff). |

| Description: Read-only. Attribute group to describe performance monitoring |
| events specific to fme. Each attribute in this group describes |
| a single performance monitoring event supported by this fme pmu. |
| The name of the file is the name of the event. |
| (See ABI/testing/sysfs-bus-event_source-devices-events). |
| |
| All supported performance monitoring events are listed below. |
