Annotated Snippet

What:           /sys/bus/event_source/devices/vpa_pmu/format
Date:           November 2024
Contact:        Linux on PowerPC Developer List <linuxppc-dev@lists.ozlabs.org>
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. Supported attribute are listed
                below::

                  event = "config:0-31" - event ID

                For example::

                  l1_to_l2_lat = "event=0x1"

What:           /sys/bus/event_source/devices/vpa_pmu/events
Date:           November 2024
Contact:        Linux on PowerPC Developer List <linuxppc-dev@lists.ozlabs.org>
Description:    Read-only. Attribute group to describe performance monitoring
                events for the Virtual Processor Area events. Each attribute
                in this group describes a single performance monitoring event
                supported by vpa_pmu. The name of the file is the name of
                the event (See ABI/testing/sysfs-bus-event_source-devices-events).

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
