PSC services

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);
   }

SaveReport

Takes a type-0x9 input buffer containing the #EventId, an input u64 ApplicationId and a type-0x5 input buffer containing the #SystemReport. No output.

nn::srepo::detail::VerifyEventId is then used with the #EventId, throwing error on failure.

The #SystemReport is used with nn::srepo::detail::VerifyReport and with last param = 0x8000, throwing error on failure.

Lastly, the actual processing func is called, returning the Result from here. Besides various cmd input being passed to this etc, this also passes the output from nn::util::GenerateUuid() to this.

SaveReportWithUser

Takes a type-0x9 input buffer containing the #EventId, an input u64 ApplicationId, a type-0x5 input buffer containing the #SystemReport and an input Uid. No output.

Same as #SaveReport except instead of calling the processing func with Uid=all-zero, the input Uid is passed instead (which must be non-zero).

SaveReportForAntiPiracy

Takes a type-0x9 input buffer containing the #EventId, an input u64 ApplicationId and a type-0x5 input buffer containing the #SystemReport. No output.

Same as #SaveReport except the #SystemReport Flags field is 1 instead of 0.

SaveReportWithUserForAntiPiracy

Takes a type-0x9 input buffer containing the #EventId, an input u64 ApplicationId, a type-0x5 input buffer containing the #SystemReport and an input Uid. No output.

Same as #SaveReportWithUser except the #SystemReport Flags field is 1 instead of 0.

SendReportWithUser

Takes an input Uid, an input u64 ApplicationId, an input bool (padded to u64), two input u32s, a type-0x9 input buffer and a TransferMemory handle. Returns an output #IAsyncContext.

The mapped TransferMemory buffer is used with nn::srepo::detail::VerifyReport, returning an error on failure.

NotifyUserList

Takes a type-0x9 input buffer containing an array of Uid. No output.

The Sf handler code (func which calls the serv obj vfunc) will throw an error if the buffer size is >0x8F (that is, >8 entries).

This gets data from a state list, then clears the is_initialized flag for each entry. Lastly when the input array count is non-zero, this loops through the input array writing each entry into the aforementioned state list. If this would run out of space, it would skip writing that entry and still continue - however this shouldn't be possible with the above Sf check. Then this returns 0.

NotifyUserDeleted

Takes an input Uid. No output.

This calls the same state-reset func as #NotifyUserList, except this passes the input Uid instead. Then this returns 0.

NotifyUserRegistered

Takes an input Uid. No output.

This calls the same state-writing func as #NotifyUserList, except this passes the input Uid instead. Then this returns 0.

NotifyUserClosed

PopLostByBufferShortageInfo

Takes an input u32. Returns two output u64s.

The input u32 must be <=1. This gets data from a state array with the specified index.

GetBufferUsageInfo

No input. Returns two output u64s.

The first u64 is a constant value, while the second u64 is from state.

SetDurationReportChatteringDetectionThreshold

Takes an input #TimeSpanType and an input u64. No output.

The input s64 must be >=1. The two input fields are written into global state, and various state is also cleared.

GetWatchdogStatistics

No input. Returns an output #WatchdogStatistics.

This gets two u64s from global state.

NotifyForegroundTransmissionResult

Takes an input u128 "nn::util::Uuid" and an input #ResultHolder. No output.

This goes through the global list of #IAsyncContext looking for an entry with data matching the input struct, then writes the input #ResultHolder into that #IAsyncContext. This Result would then be returned by #GetResult - the Event from #GetSystemEvent is also signaled.

This always returns 0.

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).
