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 What: /sys/bus/event_source/devices/dmar*/cpumask Date: Jan 2023 KernelVersion: 6.3 Contact: Kan Liang <kan.liang@linux.intel.com> Description: Read-only.
