Subject: [PATCH 04/11] perf vendor events: Update events and metrics for haswellx
From: Zhengjun Xing <zhengjun.xing@...ux.intel.com>
Update the events to v25, the metrics are based on TMA 4.4 full, update
events and metrics for haswellx by the latest event converter tools.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
to download and generate the latest events and metrics. Manually copy
the haswellx files into perf.
