As discussed in: https://lore.kernel.org/lkml/20240217005738.3744121-1-atishp@xxxxxxxxxxxx/ preferring sysfs/json events consistently (with or without a given PMU) will enable RISC-V's hope to customize legacy events in the perf tool. Some minor clean-up is performed on the way. v2. Additional cleanup particularly adding better error messages. Fix some line length issues on the earlier patches.
