Subject: [PATCH 2/2] perf vendor events intel: Update metrics for Alderlake
From: Zhengjun Xing <zhengjun.xing@...ux.intel.com>
Update JSON metrics for Alderlake to perf.
It included both P-core and E-core metrics.
P-core metrics based on TMA 4.4 (TMA_Metrics-full.csv)
E-core metrics based on E-core TMA 2.0 (E-core_TMA_Metrics.csv)
