== Ioctl3 ==
== Ioctl3 ==
Same input/output as Ioctl2, except cmdhdr_word1 is 0x100B instead of 0xC0B.
Takes a type-0x21 buffer, a type-0x22 buffer, another type-0x22 buffer, and two input u32s. Returns an output u32 (error_code).
Cmdhdr_word1 is 0x100B instead of 0xC0B.


== Cmd13 ==
== FinishInitialize ==
Takes an input u64. No output.
Takes an input u64. No output.
This sets a boolean value based on the input u64 and the value of the "nv!nv_graphics_firmware_memory_margin" system configuration, but only for "nvdrv" (the other services default to false).


Official user-processes starting with 3.0.0 now use this at the end of nvdrv service init with value 0x1.
