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

apm

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

Cmd Name Notes
0 OpenSession Returns an #ISession.
1 GetPerformanceMode
6 IsCpuOverclockEnabled

apm:p

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

Cmd Name Notes
0 OpenSession Returns an #ISession.

apm:sys

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

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

ISession

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

Cmd Name Notes
0 SetPerformanceConfiguration Takes u32 PerformanceMode and u32 PerformanceConfiguration.
1 GetPerformanceConfiguration Takes u32 PerformanceMode, returns output u32 PerformanceConfiguration.

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.
