Subject: [PATCH 2/4] [powerpc] perf vendor events: Add JSON metrics for POWER9

From: Paul Clarke <[email-masked]>
Date: Sat, 9 Feb 2019 13:14:27 -0500

Descriptions of metrics for POWER9 processors can be found in the
"POWER9 Performance Monitor Unit User’s Guide", which is currently
available on the "IBM Portal for OpenPOWER"
(https://www-355.ibm.com/systems/power/openpower/welcome.xhtml) at
https://www-355.ibm.com/systems/power/openpower/posting.xhtml?postingId=4948CDE1963C9BCA852582F800718190

This patch is for metric groups:
- dl1_reloads_percent_per_inst
- dl1_reloads_percent_per_ref
- instruction_misses_percent_per_inst
- l2_stats
- l3_stats
- pteg_reloads_percent_per_inst
- pteg_reloads_percent_per_ref
