- What: /sys/bus/event_source/devices/hv_24x7/format
- Date: September 2020
- Contact: Linux on PowerPC Developer List <[email protected]>
- 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. All supported attributes are listed
- below::
- chip = "config:16-31"
- core = "config:16-31"
- domain = "config:0-3"
- lpar = "config:0-15"
- offset = "config:32-63"
- vcpu = "config:16-31"
- For example::
- PM_PB_CYC = "domain=1,offset=0x80,chip=?,lpar=0x0"
- In this event, '?' after chip specifies that
- this value will be provided by user while running this event.
- What: /sys/bus/event_source/devices/hv_24x7/interface/catalog
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- Provides access to the binary "24x7 catalog" provided by the
- hypervisor on POWER7 and 8 systems. This catalog lists events
- available from the powerpc "hv_24x7" pmu. Its format is
- documented here:
- https://raw.githubusercontent.com/jmesmon/catalog-24x7/master/hv-24x7-catalog.h
- What: /sys/bus/event_source/devices/hv_24x7/interface/catalog_length
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- A number equal to the length in bytes of the catalog. This is
- also extractable from the provided binary "catalog" sysfs entry.
- What: /sys/bus/event_source/devices/hv_24x7/interface/catalog_version
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- Exposes the "version" field of the 24x7 catalog. This is also
- extractable from the provided binary "catalog" sysfs entry.
- What: /sys/devices/hv_24x7/interface/sockets
- Date: May 2020
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description: read only
- This sysfs interface exposes the number of sockets present in the
- system.
- What: /sys/devices/hv_24x7/interface/chipspersocket
- Date: May 2020
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description: read only
- This sysfs interface exposes the number of chips per socket
- present in the system.
- What: /sys/devices/hv_24x7/interface/coresperchip
- Date: May 2020
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description: read only
- This sysfs interface exposes the number of cores per chip
- present in the system.
- What: /sys/devices/hv_24x7/cpumask
- Date: July 2020
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description: read only
- This sysfs file exposes the cpumask which is designated to make
- HCALLs to retrieve hv-24x7 pmu event counter data.
- What: /sys/bus/event_source/devices/hv_24x7/event_descs/<event-name>
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- Provides the description of a particular event as provided by
- the firmware. If firmware does not provide a description, no
- file will be created.
- Note that the event-name lacks the domain suffix appended for
- events in the events/ dir.
- What: /sys/bus/event_source/devices/hv_24x7/event_long_descs/<event-name>
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- Provides the "long" description of a particular event as
- provided by the firmware. If firmware does not provide a
- description, no file will be created.
- Note that the event-name lacks the domain suffix appended for
- events in the events/ dir.
