== User Name to Block Maps ==
[7.0.0+] The type-0xA output buffers were replaced with type-0x22 output buffers, for the following: GetDvfsTable, GetModuleStateTable, and GetPowerDomainStateTable.
 
== IsPoweredOn ==
Takes a [[#PowerDomain|PowerDomain]] and returns a bool indicating the status of the requested voltage block.
 
== GetVoltage ==
Takes a [[#PowerDomain|PowerDomain]] and returns an u32 voltage value for the requested voltage block.
 
= pcv:arb =
This is "nn::pcv::IArbitrationManager".


=== Power Switch / Clocking / Reset ===
This service no longer exists in [8.0.0+].

Takes an u8 '''DoReset''' and a [[Bus_services#I2cDevice|DeviceCode]]. Similar to SetUpRtcResetOnShutdown from [[#bpc:r|bpc:r]], but this version assigns the provided boolean value on a per-client basis (instead of a global variable) and checks it when the current [[PSC_services#Power_Management_States|power state]] is "ReadyShutdown".

Note: max77620 GPIOs are only used internally by the driver during init, and not exposed via an API.
=== 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 [[Title_list|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 [https://tools.ietf.org/html/rfc8536 RFC8536] for more information).


= pcv:arb =
The conversion of a Tzif2 file to a TimeZoneRule structure is based on [https://github.com/eggert/tz/blob/master/localtime.c tz database code] with some custom modifications (Leap seconds aren't handled, no usage of "posixrules" and Tzif1 support stripped out).
This is "nn::pcv::IArbitrationManager".
