Subject: [PATCH 1/4] [powerpc] perf vendor events: Add JSON metrics for POWER9
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:
- cpi_breakdown
- estimated_dcache_miss_cpi
