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 |
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 |
ISession
| Cmd | Name | Notes |
|---|---|---|
| 0 | SetPerformanceConfiguration | Takes u32 PerformanceMode |
| 1 | GetPerformanceConfiguration | Takes u32 PerformanceMode, u32 PerformanceConfiguration |
PerformanceMode
| Value | Name |
|---|---|
| 0 | Handheld |
| 1 | Docked |
PerformanceConfiguration
| Value | CPU clock | GPU clock | Memory clock |
|---|---|---|---|
| 0x00010000 | 1020 | 384 | 1600 |
| 0x00010001 | 1020 | 768 | 1600 |
| 0x00010002 | 1224 | 691.2 | 1600 |
| 0x00020000 | 1020 | 230.4 | 1600 |
| 0x00020001 | 1020 | 307.2 | 1600 |
| 0x00020002 | 1224 | 230.4 | 1600 |

| 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 do not seem to be available at all (dependent on apm settings?).
Settings
| 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 (devkit only). |
| sdev_cpu_overclock_enabled | 1 | Not used as of 3.0. May have been used to allow access to 1224MHz CPU mode? |
| sdev_throttling_additional_delay_us | 4 | ? |
| sdev_throttling_additional_delay_enabled | 1 | ? |
| throttling_for_smpd_enabled | 1 | Not used as of 3.0. |
| throttling_for_undock_enabled | 1 | Not used as of 3.0. |
