em_dev_register_perf_domain() can be called from any initcall level before
The EM is registered by cpufreq drivers (or devfreq), which is later than fs_initcall, so the debugfs is setup. We even have added recently a dedicated callback into the cpufreq (register_em()) for that. Do you have such code which registers EM for CPUs (or some devfreq) earlier than this fs_initcall? I cannot find such code in mainline. Regards, Lukasz
