argh, I can't figure out how to make riscv compile :(
Are you using the riscv32 toolchain or riscv64?
And arch/riscv/include/asm/perf_event.h does
#ifdef CONFIG_RISCV_BASE_PMU
#define RISCV_MAX_COUNTERS 2
#endif
#ifndef RISCV_MAX_COUNTERS
#error "Please provide a valid RISCV_MAX_COUNTERS for the PMU."
#endif
where is RISCV_MAX_COUNTERS supposed to come from? Surely this should
be implemented in Kconfig somehow?
Sigh. Zong, did you take a look at this?
