What: /sys/bus/event_source/devices/dsa*/format Date: April 2021 KernelVersion: 5.13 Contact: Tom Zanussi <tom.zanussi@linux.intel.com> 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 What: /sys/bus/event_source/devices/dsa*/cpumask Date: April 2021 KernelVersion: 5.13 Contact: Tom Zanussi <tom.zanussi@linux.intel.com> Description: Read-only. This file always returns the cpu to which the IDXD DSA pmu is bound for access to all dsa pmu performance monitoring events. |
