== GetSaveDataCommitId ==
== OpenFileSystem ==
Takes an input u8 and u64, returns an output u64.
Takes a type-0x19 input [[#ContentPath]] and a [[#FileSystemProxyType]] as parameters. Returns an [[#IFileSystem]].


== SetSdCardEncryptionSeed ==
[2.0.0+] This function was removed.
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.


[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is (usually/always?) all-zero (however in some cases the byte at offset 0x20 is value 0x1).
== SetCurrentProcess ==
Takes a pid-descriptor.


== OpenAccessFailureDetectionEventNotifier ==
== OpenFileSystemWithPatch ==
Takes 8-bytes of input and returns an [[#IEventNotifier]].
Takes an input [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].


[8.0.0+] Now takes an additional 8-bytes of input.
Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].


== SetSaveDataSize ==
Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.


These variables are normally initialized with 32 MiB (0x2000000) and 16 MiB (0x1000000), respectively.
== OpenFileSystemWithId ==
Takes a type-0x19 input buffer, an [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].


These variables don't seem to be actually used anywhere else (?)
The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.


== SetSaveDataRootPath ==
The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);


This path is normally all-zero. When this path is non-zero, the internal OpenSaveDataFileSystem function will create a DirectorySaveDataFileSystem if the target save is a user-save + a directory exists, instead of the normal savedata filesystem object.
May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.


== SetGlobalAccessLogMode ==
The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.
Takes an input u32.


== SetGlobalAccessLogMode ==
After the [[#FileSystemProxyType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
Takes an input u32.


== GetGlobalAccessLogMode ==
When [[#FileSystemProxyType]] is '''Meta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA [[NCM_services#ProgramId|ProgramId]], then an error is thrown on mismatch.
Returns an output u32.


GlobalAccessLogMode is normally 0.
== OpenBisFileSystem ==
Takes a type-0x19 input buffer string and a [[#BisPartitionId]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].


== OutputAccessLogToSdCard ==
Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisStorage]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.
Takes a type-0x5 input buffer.


The input buffer is the string to output to the log. User-processes normally include a newline at the end.
== OpenBisStorage ==
Takes a u32 partition ID, returns 0x2EE202 for partitions which do not exist, 0x320002 for partitions which cannot be opened and a valid [[#IStorage]] handle otherwise.


User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.
== InvalidateBisCache ==
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].


When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.
== DeleteSaveDataFileSystem ==
Takes an input u64.


The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).
== CreateSaveDataFileSystem ==
Takes a 0x40-byte [[#SaveDataAttribute]], a 0x40-byte [[#SaveDataCreationInfo]], and a 0x10-byte input struct which governs creation of a saveMeta file.


== GetProgramIndexForAccessLog ==
Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060 meta file size, +4 u8 = 1 meta index which dictates meta file name.
No input, returns two 32-bit values "version" and "program_index".
 
Creates non-system savedata.
 
== CreateSaveDataFileSystemBySystemSaveDataId ==
Takes a 0x40-byte [[#SaveDataAttribute]] and a 0x40-byte [[#SaveDataCreationInfo]].
 
Creates savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.


== OpenMultiCommitManager ==
== OpenGameCardStorage ==
No input, returns an output [[#IMultiCommitManager]].
Takes two input u32s (gamecard handle, partition ID), and returns an [[#IStorage]] for the [[Gamecard_Format|partition]].


= IStorage =
== OpenGameCardFileSystem ==
This is "nn::fssrv::sf::IStorage".
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].


This is the interface for a raw device, usually a block device.
Mounts a [[Gamecard_Partition|gamecard partition]].

Returns an [[#IFileSystem]].
Takes a type-0x45 buffer, an offset and length.


== Flush ==
Permissions aren't checked until the specified save is successfully found.
No input.


== SetSize ==
Only one process (specifically only one [[#IFileSystem]] session) can mount a given savedata at any given time (this includes SystemSaveData).
Takes a size.


== GetSize ==
== OpenSaveDataFileSystemBySystemSaveDataId ==
Returns a size.
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte [[#SaveDataAttribute]]. Web-applet only uses value0 for the input u8.
 
Returns an [[#IFileSystem]].


= IFileSystem =
Mounts savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.
This is "nn::fssrv::sf::IFileSystem".


There are two main implementations of this interface:
== OpenReadOnlySaveDataFileSystem ==
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte [[#SaveDataAttribute]], and returns an [[#IFileSystem]].


* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
Mounts SaveData as ReadOnly.
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.


There are two adapter classes to convert between these interfaces:
== ReadSaveDataFileSystemExtraDataBySaveDataSpaceId ==
Takes an input u8 [[#SaveDataSpaceId]], an input u64 saveID, and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].


* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
== ReadSaveDataFileSystemExtraData ==
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.
Takes an input u64 saveID and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].


When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
== OpenSaveDataInfoReader ==
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.
No input, returns an output [[#ISaveDataInfoReader]].

== OpenFile ==
== OpenSaveDataTransferManagerForSaveDataRepair ==
Takes a type-0x19 input buffer for the path, and an u32 '''mode'''. '''mode''' controls how the file is opened, based on which bits are set:

Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.


{| class="wikitable" border="1"
[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is (usually/always?) all-zero (however in some cases the byte at offset 0x20 is value 0x1).

Takes a type-0x6 output buffer. Returns an output u64 for total output entries. This buffer contains an array of [[#SaveDataInfo]].


This is used to get [[#SaveDataInfo]] for all savedata on the system (or all savedata for the current [[#SaveDataSpaceId]]). When used multiple times, it will resume reading where it left off, until no more entries are available (in that case the out u64 is value 0).
== SetSaveDataRootPath ==
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);
 
This path is normally all-zero. When this path is non-zero, the internal OpenSaveDataFileSystem function will create a DirectorySaveDataFileSystem if the target save is a user-save + a directory exists, instead of the normal savedata filesystem object.

When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.
| 3 || [2.0.0+] GetSdCardUserAreaSize
 
The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).
 
== GetProgramIndexForAccessLog ==
No input, returns two 32-bit values "version" and "program_index".

There are two main implementations of this interface:
 
* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.
 
There are two adapter classes to convert between these interfaces:
 
* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.
 
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.

No input, returns an u32 '''GameCardHandle'''.
Takes a type-0x19 input buffer for the path, and an u32 '''mode'''. '''mode''' controls how the file is opened, based on which bits are set:


== GetGameCardUpdatePartitionInfo ==
* When bit 0 is set, the file is Readable: you can use the Read operation.
Returns a [[NCM_services#ProgramId|ProgramId]] and the title-version for it.
* When bit 1 is set, the file is Writable: you can use the Write operation.
* When bit 2 is set, the file is Appendable: unless this bit is set, you will not be able to write beyond the end of a file (such writes will result in an error 0x307202)


* Output u32 with ARMS-gamecard: title-version v131162. This is the title-version for [[2.1.0]], which is the sysupdate included with this gamecard. Launch-day gamecards return title-version v450.
