"hv_24x7" pmu interface events needs system dependent parameter like socket/chip/core. For example, hv_24x7 chip level events needs specific chip-id to which the data is requested should be added as part of pmu events. So to enable JSON file support to "hv_24x7" interface, patchset expose total number of sockets and chips per-socket details in sysfs files (sockets, chips) under "/sys/devices/hv_24x7/interface/". To get sockets and number of chips per sockets, patchset adds a rtas call with token "PROCESSOR_MODULE_INFO" to get these details. Patchset also handles partition migration case to re-init these system depended parameters by adding proper calls in post_mobility_fixup() (mobility.c). v6: http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=164769 Changelog: v6 -> v7 - Split patchset into two patch series, one with kernel changes and another with perf tool side changes. This pachset contain all kernel side changes.
