Subject: [PATCH 36/63] perf vendor events intel: Update all the Intel JSON metrics from TMAM 3.6.
From: Haiyan Song <haiyanx.song@...el.com>
New Metrics:
- DSB_Switches: fraction of cycles CPU was stalled due to switches from DSB to MITE pipeline [all]
- L2_Evictions_{Silent|NonSilent}_PKI: L2 {silent|non silent} ecivtions rate per Kilo instruction [SKX+]
- IpFarBranch - Instructions per Far Branch
Other Enhancements & fixes:
- KBLR/CFL & CLX move to separate columns (no column sharing via if #model)
- Re-organized/renamed Metric Group

Frontend denotes the first part of the processor core responsible to fetch operations that are executed later on by the Backend part. Within the Frontend; a branch predictor predicts the next address to fetch; cache-lines are fetched from the memory subsystem; parsed into instructions; and lastly decoded into micro-ops (uops). Ideally the Frontend can issue 4 uops every cycle to the Backend. Frontend Bound denotes unutilized issue-slots when there is no Backend stall; i.e. bubbles where Frontend delivered no uops while Backend could have accepted them.
