Dwords and Parameters desc

looking at documentation, I realized that I can not find information about dwords and parameters.
all I found is open-gpu-kernel-modules/nvrm_registry.h at main · NVIDIA/open-gpu-kernel-modules · GitHub
so i have a couple of questions

  1. Are there any documentation for dwords and parameters?
  2. my “friend” says that he has documentation for all dwords and parameters
    as proof he threw off the screenshots

and this

"PS_LOADBALANCE_MODE" => 
    type   => $type_int,
    desc   => "",
    enums  => [ "FORCE_CPU_LIMITED", "FORCE_ALWAYS_OFF", "FORCE_GPU_LIMITED", "FORCE_ALWAYS_ON", "FORCE_LOADBALANCE", "FORCE_LB", "FORCE_ALTERNATE", "FORCE_ALTERNATE_EACH_DECISION", "FORCE_HIGH_FREQUENCY_MODE", ],
    values => { "FORCE_ALTERNATE" => 0x00000003, "FORCE_ALTERNATE_EACH_DECISION" => 0x00000004, "FORCE_ALWAYS_OFF" => 0x00000000, "FORCE_ALWAYS_ON" => 0x00000001, "FORCE_CPU_LIMITED" => 0x00000000, "FORCE_GPU_LIMITED" => 0x00000001, "FORCE_HIGH_FREQUENCY_MODE" => 0x00000005, "FORCE_LB" => 0x00000002, "FORCE_LOADBALANCE" => 0x00000002, },
},

PS_FRAMERATE_LOGGER" => {
type => $type_int,
desc => “FPS overlay and simple text logging”,
enums => [ “DISABLED”, “DISPLAY”, “LOGTOFILE”, “LOGTOETW”, “ALLOWDWM”, ],
values => { “ALLOWDWM” => 0x00000008, “DISABLED” => 0x00000000, “DISPLAY” => 0x00000001, “LOGTOETW” => 0x00000004, “LOGTOFILE” => 0x00000002, },
},

“LATENCY” => {
type => $type_int,
desc => "Reduces latency by limiting the number of frames the CPU can prepare before the frames are processed by the GPU. It also determines how multiple CPU-cores are used by the driver ",
enums => [ “BEST_PERFORMANCE”, “LOW_LATENCY”, “LOWEST_LATENCY”, ],
values => { “BEST_PERFORMANCE” => 0x0, “LOWEST_LATENCY” => 0x2, “LOW_LATENCY” => 0x1, },
},

type => $type_bool,
desc => “Allow DWM to use low latency node”,
enums => [ “OFF”, “0”, “FALSE”, “DISABLED”, “ON”, “1”, “TRUE”, “ENABLED”, ],
values => { “0” => 0x00000000, “1” => 0x00000001, “DISABLED” => 0x00000000, “ENABLED” => 0x00000001, “FALSE” => 0x00000000, “OFF” => 0x00000000, “ON” => 0x00000001, “TRUE” => 0x00000001, },
},

now the question where did he get it from?
