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).

This file always returns cpu which the PMU is bound for access to all fme pmu performance monitoring events. What: /sys/bus/event_source/devices/dfl_fmeX/events Date: April 2020 KernelVersion: 5.8 Contact: Wu Hao <hao.wu@intel.com> 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.
