NvServiceType

enum NvServiceType

NvServiceType, for __nx_nv_service_type.

Enumerator
NvServiceType_Auto	This is the default. Automatically select the type using appletGetAppletType.
NvServiceType_Application	Initializes nvdrv.
NvServiceType_Applet	Initializes nvdrv:a.
NvServiceType_System	Initializes nvdrv:s.
NvServiceType_Factory	Initializes nvdrv:t.
