| H A D | hv-24x7.c | 8ba21426 Mon May 25 05:43:04 CDT 2020 Kajol Jain <kjain@linux.ibm.com> powerpc/hv-24x7: Add rtas call in hv-24x7 driver to get processor details
For hv_24x7 socket/chip level events, specific chip-id to which
the data requested should be added as part of pmu events.
But number of chips/socket in the system details are not exposed.
Patch implements read_24x7_sys_info() to get system parameter values
like number of sockets, cores per chip and chips per socket. Rtas_call
with token "PROCESSOR_MODULE_INFO" is used to get these values.
Subsequent patch exports these values via sysfs.
Patch also make these parameters default to 1.
