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

apm

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

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

Cmd	Name	Notes
0	OpenSession	Returns an #ISession.

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

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.

Value	Name
0	Handheld
1	Docked

Value	CPU clock	GPU clock	Memory clock
0x00010000	1020	384	1600
0x00010001	1020	768	1600
0x00010002	1224	691.2	1600

0x00020002	1224	230.4	1600
0x00020003	1020	307	1331.2
0x00020004	1020	384	1331.2
0x00020005	1020	307.2	1065.6
0x00020006	1020	384	1065.6
0x92220007	1020	460.8	1600
0x92220008	1020	460.8	1331.2

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.

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

Cmd	Name
0	Initialize

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

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

Key	Size	Notes
battery_draining_enabled	1	?
performance_mode_policy	strlen	"auto": use boost mode when docked. "normal": never use boost mode. "boost": always use boost mode (SDEV only).
sdev_cpu_overclock_enabled	1	SDEV only. Used to allow access to 1224MHz CPU mode.
sdev_throttling_additional_delay_us	4	SDEV only.
sdev_throttling_additional_delay_enabled	1	SDEV only.
throttling_for_smpd_enabled	1	Not used as of 3.0.
throttling_for_undock_enabled	1	Not used as of 3.0.
