Query: Supporting RISC-V Performance Counters through Performance analysis
  tools for Linux (Perf)   Increased attention to RISC-V in Cloud, Data Center, Automotive and
Networking applications, has been fueling the move of RISC-V to the
high-performance computing scenario. However, lack of powerful performance
monitoring tools will result in poorly optimized applications and,
consequently, a limited computing performance. While the RISC-V ISA already
defines a hardware performance monitor (HPM), current software gives limited
support for monitoring performance. In this paper we introduce extensions and
modifications to the Performance analysis tools for Linux(perf/perf_events),
Linux kernel, and OpenSBI, aiming to achieve full support for the RISC-V
performance monitoring specification. Preliminary testing and evaluation was
carried out in Linux 5.7 running on a FPGA booted CVA6 CPU, formerly named
Ariane, showing a monitoring overhead of 0.283%.
