Currently, when the CPU is doing suspend to ram, we don't save pmu counter register and its content will be lost. To ensure perf profiling is not affected by suspend to ram, this patch is based on arm_pmu CPU_PM notifier and implements riscv pmu pm notifier. In the pm notifier, we stop the counter and update the counter value before suspend and start the counter after resume.
