VS-extension improvements ver. vs-5.x [CMN]

We have to create new CMN window. CMN is enabled on the system if wperf test command will return cmn_device.version_name with value different to CMN_FAMILY_UNKNOWN

So:

• if cmn_device.version_name == CMN_FAMILY_UNKNOWN - CMN device is not available.

• If cmn_device.version_name == e.g. CMN700_FAMILY CMN is detected.

See https://linaro.atlassian.net/browse/WPERF-1089 to understand how -e with arm_cmn_0// can be sheped. In short it can be:

• -e arm_cmn_0/<list_of_filters>/

• -e arm_cmn_0/hnf_cache_miss,bynodeid,nodeid=0x24/,arm_cmn_0/type=0x5,eventid=0x1,bynodeid,nodeid=0x24/(two arm_spe_0// defined).

• As above but it can be grouped with outer {} brackets.

Considerations

• Support for process spawn (priority low)

• Support for timeline (priority high)

• event name, for example hnf_cache_miss is type=0x5,eventid=0x1 because:

  • WPERF_TS_CMN_DEVICE(CMN700_FAMILY, HNF, 5, "Telemetry Specification (PMU Events, Metrics and Methodology) for HNF CMN")

  • WPERF_TS_CMN_EVENTS(CMN700_FAMILY, HNF, PMU_HNF_CACHE_MISS_EVENT, 0x0001, "pmu_hnf_cache_miss_event", "PMU_HNF_CACHE_MISS_EVENT", "Counts total cache misses in first lookup result (high priority)")

Definition of done

• Add new modal window for CMN counting. We want to support widgets for command line options like:

  • wperf stat

  • -e arm_cmn_0//

    • Plus filters that CMN can support. For development please hardcode some filters like:

      • Note: Ask Everton to help you understand type of input we can put in each “filter”.

      • nodeid - An integer or hex number indicating the nodeid this will have no effect if bynodeid is not set

      • bynodeid - Defines that the event is related to a particular nodeid, if this flag is found nodeid is required.

      • type - A number or hex with the device type, valid types are at the moment directly takes from Arm ARM. This is required.

      • eventid - A number or hex defining the eventid for this event.

      • dtcid - A number or hex defining the DTC domain for this event.

      • event - A string taken from Telemetry solution an event already contains type and eventid information.

        • Example event names per CMN devices are: https://gitlab.com/Linaro/WindowsPerf/windowsperf/-/blob/main/wperf-common/cmn700.def?ref_type=heads#L39

  • Flags:

    • --dpc-ovf, --enable-dpc-overflow (bool)

    • --dtc-ovf, --enable-dtc-overflow (bool)

    • --timeout / sleep N
