Thanks for checking, but there is a 1-to-1 relation ship now:

enum PP_SMC_POWER_PROFILE {
        PP_SMC_POWER_PROFILE_BOOTUP_DEFAULT = 0x0,
        PP_SMC_POWER_PROFILE_FULLSCREEN3D = 0x1,
        PP_SMC_POWER_PROFILE_POWERSAVING  = 0x2,
        PP_SMC_POWER_PROFILE_VIDEO        = 0x3,
        PP_SMC_POWER_PROFILE_VR           = 0x4,
        PP_SMC_POWER_PROFILE_COMPUTE      = 0x5,
        PP_SMC_POWER_PROFILE_CUSTOM       = 0x6,
        PP_SMC_POWER_PROFILE_COUNT,
};

vs

        static const char *profile_name[] = {
                                        "BOOTUP_DEFAULT",
                                        "3D_FULL_SCREEN",
                                        "POWER_SAVING",
                                        "VIDEO",
                                        "VR",
                                        "COMPUTE",
                                        "CUSTOM"};


unless I'm missing something because I've not had enough coffee.
