		Description: Read-only. Attribute group to describe the magic bits
		that go into perf_event_attr.config,
		perf_event_attr.config1 or perf_event_attr.config2 for
		the IOMMU 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, perf_event_attr.config1,
		or perf_event_attr.config2. All supported attributes
		are listed below (See the VT-d Spec 4.0 for possible
		attribute values)::

		event = "config:0-27" - event ID
		event_group = "config:28-31" - event group ID

		filter_requester_en = "config1:0" - Enable Requester ID filter
		filter_domain_en = "config1:1" - Enable Domain ID filter
		filter_pasid_en = "config1:2" - Enable PASID filter
		filter_ats_en = "config1:3" - Enable Address Type filter
		filter_page_table_en= "config1:4" - Enable Page Table Level filter
		filter_requester_id = "config1:16-31" - Requester ID filter
		filter_domain = "config1:32-47" - Domain ID filter
		filter_pasid = "config2:0-21" - PASID filter
		filter_ats = "config2:24-28" - Address Type filter
		filter_page_table = "config2:32-36" - Page Table Level filter

		Description: Read-only. This file always returns the CPU to which the
		IOMMU pmu is bound for access to all IOMMU pmu performance
		monitoring events.
