Subject: [PATCH 21/91] perf vendor events power9: Add hv_24x7 socket/chip level metric events

From: Kajol Jain <kjain@...ux.ibm.com>

The hv_24×7 feature in IBM® POWER9™ processor-based servers provide the
facility to continuously collect large numbers of hardware performance
metrics efficiently and accurately.

This patch adds hv_24x7  metric file for different Socket/chip
resources.

Result:

power9 platform:

  command:# ./perf stat --metric-only -M Memory_RD_BW_Chip -C 0 -I 1000

     1.000096188          0.9           0.3
     2.000285720          0.5           0.1
     3.000424990          0.4           0.1

  command:# ./perf stat --metric-only -M PowerBUS_Frequency -C 0 -I 1000

     1.000097981          2.3           2.3
     2.000291713          2.3           2.3
     3.000421719          2.3           2.3
     4.000550912          2.3           2.3
