APM is utilized for setting system performance profiles including clocks for CPU, GPU, and memory.

apm

This is "nn::apm::IManager".

This was moved to AM with [8.0.0+] and is now a shim for apm:am.

Cmd Name
0 #OpenSession
1 GetPerformanceMode
6 [7.0.0+] #IsCpuOverclockEnabled

OpenSession

Returns an #ISession.

IsCpuOverclockEnabled

No input, returns an output u8 bool.

apm:p

This is "nn::apm::IManagerPrivileged".

This service no longer exists in [8.0.0+].

Cmd Name
0 OpenSession

OpenSession

Returns an #ISession.

apm:am

This is "nn::apm::IManager".

This was added with [8.0.0+] and is the same as the old apm service.

apm:sys

This is "nn::apm::ISystemManager".

Cmd Name
0 RequestPerformanceMode
1 GetPerformanceEvent
2 GetThrottlingState
3 GetLastThrottlingState
4 ClearLastThrottlingState
5 [5.0.0+] LoadAndApplySettings
6 [7.0.0+] #SetCpuBoostMode
7 [7.0.0+] #GetCurrentPerformanceConfiguration

GetPerformanceEvent

Returns an #ISession.

SetCpuBoostMode

Takes an u32 #CpuBoostMode.

CpuBoostMode

Mode Description
0 Disabled.
1 Use performance configurations 0x92220009 and 0x9222000A, or 0x9222000B and 0x9222000C.
2 Use performance configurations 0x9222000B and 0x9222000C.

GetCurrentPerformanceConfiguration

Returns the currently active #PerformanceConfiguration (default value is 0x00020003).

ISession

This is "nn::apm::ISession".

Cmd Name
0 SetPerformanceConfiguration
1 GetPerformanceConfiguration
2 [8.0.0+] #SetCpuOverclockEnabled

SetPerformanceConfiguration

Takes an u32 #PerformanceMode and an u32 #PerformanceConfiguration.

GetPerformanceConfiguration

Takes an u32 #PerformanceMode and returns an output u32 #PerformanceConfiguration.

SetCpuOverclockEnabled

Takes an input u8 bool, no output.

Clocks are all in MHz.

Configurations 0x10001 and 0x20000 are only available while docked. Configurations 0x10002 and 0x20002 are only available for SDEV units.

Some of these require apm:p.

fgm, fgm:0, fgm:9

This is "nn::fgm::sf::ISession".

Cmd Name
0 Initialize

IRequest

This is "nn::fgm::sf::IRequest".

Cmd Name
0 Initialize
1 Set
2 Get
3 Cancel

fgm:dbg

This is "nn::fgm::sf::IDebugger".

Cmd Name
0 Initialize
1 Read
2 Cancel
