- What: /sys/bus/event_source/devices/hv_gpci/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::
- counter_info_version = "config:16-23"
- length = "config:24-31"
- partition_id = "config:32-63"
- request = "config:0-31"
- sibling_part_id = "config:32-63"
- hw_chip_id = "config:32-63"
- offset = "config:32-63"
- phys_processor_idx = "config:32-63"
- secondary_index = "config:0-15"
- starting_index = "config:32-63"
- For example::
- processor_core_utilization_instructions_completed = "request=0x94,
- phys_processor_idx=?,counter_info_version=0x8,
- length=8,offset=0x18"
- In this event, '?' after phys_processor_idx specifies this value
- this value will be provided by user while running this event.
- What: /sys/bus/event_source/devices/hv_gpci/interface/collect_privileged
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- '0' if the hypervisor is configured to forbid access to event
- counters being accumulated by other guests and to physical
- domain event counters.
- '1' if that access is allowed.
- What: /sys/bus/event_source/devices/hv_gpci/interface/ga
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- 0 or 1. Indicates whether we have access to "GA" events (listed
- in arch/powerpc/perf/hv-gpci.h).
- What: /sys/bus/event_source/devices/hv_gpci/interface/expanded
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- 0 or 1. Indicates whether we have access to "EXPANDED" events (listed
- in arch/powerpc/perf/hv-gpci.h).
- What: /sys/bus/event_source/devices/hv_gpci/interface/lab
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- 0 or 1. Indicates whether we have access to "LAB" events (listed
- in arch/powerpc/perf/hv-gpci.h).
- What: /sys/bus/event_source/devices/hv_gpci/interface/version
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- A number indicating the version of the gpci interface that the
- hypervisor reports supporting.
- What: /sys/bus/event_source/devices/hv_gpci/interface/kernel_version
- Date: February 2014
- Contact: Linux on PowerPC Developer List <[email protected]>
- Description:
- A number indicating the latest version of the gpci interface
- that the kernel is aware of.
- What: /sys/devices/hv_gpci/cpumask
- Date: October 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-gpci pmu event counter data.
