PSC (Power State Control) provides services related to power state changes in the system.

Concept

psc:m allows a process to register a module that depends on power management in some way. A client calls GetPmModule to receive an IPmModule (Power Managed Module), and then calls IPmModule->Initialize(module_id, module_dependency_list) where module_id is the ModuleId enum member for the client, and the dependency list is an array of module IDs for the modules that this depends on. Initialize() returns an event handle that the client can wait on to be notified of a power state change.

psc:c allows a module to the power state controller for the system (in practice, AM is the only client to the controller). IPmControl->DispatchRequest() is used notify all IPmModules of a state change.

For example, FS registers itself as an IPmModule with dependencies on pinmux, gpio, pcv, tma, and initializes the SD card once those dependencies have registered..

It then does (basically) the following pseudocode (actual code located at .text + 0xB2DB0 in 6.0.0 FS):

   while (true) {
       Fs_IPmModule->WaitSignaled();
       
       Fs_IPmModule->GetRequest(&state);
       switch (state) {
           case WakingUp:
               /* hardware devices are woken up here */
           case GoingToSleep:
               /* hardware devices are put to sleep here */
           case ShuttingDown:
               /* hardware devices are turned off here */
       }
       
       Fs_IPmModule->Acknowledge(state);
   }

202 ToPosixTimeWithMyRule Takes an input #CalendarTime, an type-0xA output buffer for #PosixTime array, and returns an output s32.

LoadLocationNameList

Takes an input s32 LocationName_index and a type-0x6 output buffer for #LocationName, returns an output s32 for total output entries.

LocationName

This contains a TimeZone location string with a max size of 0x24 bytes.

TimeZoneRule

This is an 0x4000-byte struct. Official sw uses fixed-size 0x4000 for the buffer size with the above commands.

This is loaded from the TimeZoneBinary title with the specified LocationName under the zoneinfo/ directory, the content is then converted into this TimeZoneRule structure.

The files contained under zoneinfo/ directory are Tzif2 files without Tzif1 header and data at the begining of them (see RFC8536 for more information).

The conversion of a Tzif2 file to a TimeZoneRule structure is based on tz database code with some custom modifications (Leap seconds aren't handled, no usage of "posixrules" and Tzif1 support stripped out).
