Subject: [PATCH v4 0/5] RISC-V: Create unique identification for SoC PMU
Date:   Fri, 24 Jun 2022 19:00:50 +0300

This series aims to provide matching vendor SoC with corresponded JSON bindings.

The ID string is proposed to be in form of MVENDORID-MARCHID-MIMPID, for example 
for Sifive Unmatched the corresponding string will be:

0x489-0x8000000000000007-0x[[:xdigit:]]+,v1,sifive/u74,core

Where MIMPID can vary as all impl supported the same number of events, this might not 
be true for all future SoC however.

Also added 3 counters which are standart for all RISC-V implementations and SBI firmware 
events prerry names, as any firmware that supports SBI PMU should also support firmare 
events.

v3->v4:
- drop pmuid in riscv_pmu_sbi, we are using /proc/cpuinfo
- rework util/header.c to use /proc/cpuinfo
- add SBI firmware events
- add firmware and std arch events to U74 pmu bindings
- change U74 id string and description in mapfile.csv

  perf tools riscv: Add support for get_cpuid_str function
  perf arch events: riscv arch std event files
  perf arch events: riscv sbi firmare std event files
  perf vendor events riscv: add Sifive U74 JSON file
