Update driver to export formatting and event information to sysfs so it can be used by the perf user space tools with the syntaxes: perf stat -e cpu/event=0x05 perf stat -e cpu/event=0x05,firmware=0x1/ 63-bit is used to distinguish hardware events from firmware. Firmware events are defined by "RISC-V Supervisor Binary Interface Specification". perf stat -e cpu/event=0x05,firmware=0x1/ is equivalent to perf stat -e r8000000000000005 Suggested-by: João Mário Domingos <joao.mario@tecnico.ulisboa.pt> Signed-off-by: Nikita Shubin <n.shubin@yadro.com> Link: https://github.com/riscv-non-isa/riscv-sbi-doc/blob/master/riscv-sbi.adoc Link: https://lore.kernel.org/r/20220628114625.166665-2-nikita.shubin@maquefel.me Signed-off-by: Will Deacon <will@kernel.org> |
