Takes an [[NCM_services#ProgramId|ProgramId]] and a [[#ContentPath]]. Returns an [[#IFileSystem]].
Takes a type-0x19 input buffer containing a [[#FspPath]] and an input [[NCM_services#ProgramId|ProgramId]]. Returns an [[#IFileSystem]].


[10.0.0+] This now takes an additional type-0x1A output buffer.
[10.0.0+] Now takes an additional type-0x1A output buffer.
 
[16.0.0+] Now takes an additional input [[#ContentAttributes]].
 
[17.0.0+] Now takes a type-0x6 output buffer instead of a type-0x1A output buffer.
 
[20.0.0+] Now no longer takes a type-0x19 input buffer containing a [[#FspPath]] and instead takes an input [[NCM_services#StorageId|StorageId]].


== IsArchivedProgram ==
== IsArchivedProgram ==
Takes an u64 ProcessId. Returns a bool (1 if the process id's [[#ContentPath]] ends in ".nca").

== RegisterProgram ==
== RegisterProgram ==
Takes a [[NCM_services#StorageId|StorageId]], an u64 ProcessId, a [[NCM_services#ProgramId|ProgramId]], a 0x1C type-A buffer for the [[NPDM#FS_Access_Header| FS Access Header]], and a 0x2C type-A buffer for the [[NPDM#FS_Access_Control| FS Access Control]]
Takes an input [[NCM_services#StorageId|StorageId]], an input u64 ProcessId, an input [[NCM_services#ProgramId|ProgramId]], a type-0x5 input buffer containing an [[NPDM#ACID|ACID]] [[NPDM#FsAccessControl|FsAccessControl]], and a type-0x5 input buffer containing an [[NPDM#ACI0|ACI0]] [[NPDM#FsAccessControl|FsAccessControl]].


Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.
Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.
[20.0.0+] Now takes an additional input [[#FsAccessControlRestrictionMode]].


== UnregisterProgram ==
== UnregisterProgram ==
Takes a pid. Removes registered FS permissions for that PID.
Takes an input u64 ProcessId. No output.
 
Removes registered FS permissions for that PID.


== SetEnabledProgramVerification ==
== SetEnabledProgramVerification ==
Seems to sets a global flag to inputval & 1.
Takes an input bool. No output.


When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.

Note that the functions check whether or not at least one bit is set in the mask. This means that, you don't need to set 0xFFFFFFFFFFFFFFFF to get all permissions: it suffices to set 0x8000000000000000.

If nn::spl::IsDebugMode() is disabled (retail behavior), the FS sysmodule masks the permission descriptor with 0x3FFFFFFFFFFFFFFF upon process registration.

|-
The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
| 0x7 || CanDeleteSaveData || 0x8000000000000060 || [[#DeleteSaveDataFileSystem]], RegisterSaveDataFileSystemAtomicDeletion
 
|-
The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
| 0x8 || CanCreateSystemSaveData || 0x8000000000000028 || CreateSaveDataFileSystemBySystemSaveDataId
 
|-
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.
| 0x9 || CanCreateOthersSystemSaveData || 0x8000000000000020 || CreateSaveDataFileSystemBySystemSaveDataId
 
|-
The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.

== OpenFileSystem ==
== OpenGameCardDetectionEventNotifier ==
Takes a type-0x19 input [[#ContentPath]] and a [[#FileSystemProxyType]] as parameters. Returns an [[#IFileSystem]].
This command returns a session to a port implementing the [[#IEventNotifier]] interface.


[2.0.0+] This function was removed.
== SimulateDeviceDetectionEvent ==
Takes a total of 0xC-bytes of input, no output.


== SetCurrentProcess ==
== VerifySaveDataFileSystem ==
Takes a pid-descriptor.
Takes an unknown input u64 and a type-0x6 output buffer.


== OpenFileSystemWithPatch ==
The input u64 high-byte must be non-zero, otherwise an [[Error_codes|error]] is returned(0xE02).
Takes an input [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].


Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].
== GetSaveDataCommitId ==
Takes an input u8 and u64, returns an output u64.


Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.
== SetSdCardEncryptionSeed ==
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.


== OpenFileSystemWithId ==
[[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 all-zero except for the byte at offset 0x20. This byte is set to 1 by NS if the SD card has been mounted successfully and is subsequently passed to SetSdCardAccessibility.
Takes a type-0x19 input buffer, an [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].


The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
== OpenAccessFailureDetectionEventNotifier ==
Takes 8-bytes of input and returns an [[#IEventNotifier]].


The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
[8.0.0+] Now takes an additional 8-bytes of input.


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.
== SetSaveDataSize ==
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.


The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.
These variables are normally initialized with 32 MiB (0x2000000) and 16 MiB (0x1000000), respectively.


After the [[#FileSystemProxyType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
These variables don't seem to be actually used anywhere else (?)


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.
== SetSaveDataRootPath ==
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);


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


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.
== SetGlobalAccessLogMode ==
Takes an input u32.


== OpenBisStorage ==
== SetGlobalAccessLogMode ==
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.
Takes an input u32.


== InvalidateBisCache ==
== GetGlobalAccessLogMode ==
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].
Returns an output u32.


== DeleteSaveDataFileSystem ==
GlobalAccessLogMode is normally 0.
Takes an input u64.


== CreateSaveDataFileSystem ==
== OutputAccessLogToSdCard ==
Takes a 0x40-byte [[#SaveDataAttribute]], a 0x40-byte [[#SaveDataCreationInfo]], and a 0x10-byte input struct which governs creation of a saveMeta file.
Takes a type-0x5 input buffer.


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.
The input buffer is the string to output to the log. User-processes normally include a newline at the end.


Creates non-system savedata.
User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.


== CreateSaveDataFileSystemBySystemSaveDataId ==
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.
Takes a 0x40-byte [[#SaveDataAttribute]] and a 0x40-byte [[#SaveDataCreationInfo]].


Creates savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.
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).


== OpenGameCardStorage ==
== GetProgramIndexForAccessLog ==
Takes two input u32s (gamecard handle, partition ID), and returns an [[#IStorage]] for the [[Gamecard_Format|partition]].
No input, returns two 32-bit values "version" and "program_index".


== OpenGameCardFileSystem ==
== OpenMultiCommitManager ==
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].
No input, returns an output [[#IMultiCommitManager]].


Mounts a [[Gamecard_Partition|gamecard partition]].
== OpenBisWiper ==
Takes an input u64 size and a TransferMemory handle. Returns an output [[#IWiper]].


== CreateSaveDataFileSystemWithHashSalt ==
= IStorage =
Takes a total of 0xB0-bytes of input, no output.
This is "nn::fssrv::sf::IStorage".


== OpenSaveDataFileSystem ==
This is the interface for a raw device, usually a block device.
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte [[#SaveDataAttribute]]. Official user-process code is only known to use value 1 for the u8.


Returns an [[#IFileSystem]].

Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte [[#SaveDataAttribute]]. Web-applet only uses value0 for the input u8.
No input.


Returns an [[#IFileSystem]].
== SetSize ==
Takes a size.


Mounts savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.
== GetSize ==
Returns a size.


== OpenReadOnlySaveDataFileSystem ==
= IFileSystem =
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte [[#SaveDataAttribute]], and returns an [[#IFileSystem]].
This is "nn::fssrv::sf::IFileSystem".


Mounts SaveData as ReadOnly.
There are two main implementations of this interface:


== ReadSaveDataFileSystemExtraDataBySaveDataSpaceId ==
* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
Takes an input u8 [[#SaveDataSpaceId]], an input u64 saveID, and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.


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


== OpenSaveDataInfoReader ==
* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
No input, returns an output [[#ISaveDataInfoReader]].
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.


== OpenSaveDataInfoReaderBySaveDataSpaceId ==
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
Takes an input u8 [[#SaveDataSpaceId]], returns an output [[#ISaveDataInfoReader]].
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.


== FindSaveDataWithFilter ==

* When bit 0 is set, the file is Readable: you can use the Read operation.
Takes a [[#ContentStorageId]]. Invalid values return 0x2EE202.
* 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)


Returns an [[#IFileSystem]] with NCA files. The read data from these files is identical to the data read by [[NCM_services#ReadContentIdFile]].
== OpenDirectory ==
Takes a type-0x9 input buffer for the path and an u64 '''filter_flags'''. '''filter_flags''' controls what type of entries are read by the [[#IDirectory]]: bitmask 0x1 = directories, bitmask 0x2 = files.


== OpenCloudBackupWorkStorageFileSystem ==
== Commit ==
Takes 4-bytes of input, returns an [[#IFileSystem]].
Like [https://3dbrew.org/wiki/FS:ControlArchive 3DS], this has to be used after writing to savedata for the changes to take affect.

== OpenDeviceOperator ==
== Read ==
This command returns a session to a port implementing the [[#IDeviceOperator]] interface.
Takes a type-0x6 output buffer. Returns an output u64(?) for the total number of read entries, this is 0 when no more entries are available.


== OpenSdCardDetectionEventNotifier ==
The output buffer contains the read array of [[#DirectoryEntry]]. This doesn't include entries for "." and "..".
This command returns a session to a port implementing the [[#IEventNotifier]] interface.


== OpenGameCardDetectionEventNotifier ==
== GetEntryCount ==
This command returns a session to a port implementing the [[#IEventNotifier]] interface.
Returns an u64 for the total number of readable entries.


== SimulateDeviceDetectionEvent ==
= DirectoryEntry =
Takes a total of 0xC-bytes of input, no output.
This is "nn::fs::DirectoryEntry".


== VerifySaveDataFileSystem ==
{| class="wikitable" border="1"
Takes an unknown input u64 and a type-0x6 output buffer.

|}


The input u64 high-byte must be non-zero, otherwise an [[Error_codes|error]] is returned(0xE02).
= DirectoryEntryType =
This is "nn::fs::DirectoryEntryType".


== GetSaveDataCommitId ==
An s8 value indicating a directory entry type. The current values are:
Takes an input u8 and u64, returns an output u64.


== SetSdCardEncryptionSeed ==
{| class="wikitable" border="1"
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.
|-
! Value || Description
|-
| 0 || Directory
|-
| 1 || File
|}


[[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).
= IFile =
This is "nn::fssrv::sf::IFile".


== OpenAccessFailureDetectionEventNotifier ==

= ISaveDataInfoReader =
This is "nn::fssrv::sf::ISaveDataInfoReader".


== SetSaveDataSize ==
{| class="wikitable" border="1"
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.
|-
! Cmd || Name
|-
| 0 || [[#ReadSaveDataInfo]]
|}


These variables are normally initialized with 32 MiB (0x2000000) and 16 MiB (0x1000000), respectively.
== ReadSaveDataInfo ==
Takes a type-0x6 output buffer. Returns an output u64 for total output entries. This buffer contains an array of [[#SaveDataInfo]].


These variables don't seem to be actually used anywhere else (?)
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 ==
= IDeviceOperator =
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);
This is "nn::fssrv::sf::IDeviceOperator".


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.

== GetGlobalAccessLogMode ==
| 2 || [2.0.0+] [[#GetSdCardCid]]
Returns an output u32.
|-
 
| 3 || [2.0.0+] [[#GetSdCardUserAreaSize]]
GlobalAccessLogMode is normally 0.
 
== OutputAccessLogToSdCard ==
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.
 
User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.
 
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.
 
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".
 
== OpenMultiCommitManager ==
No input, returns an output [[#IMultiCommitManager]].
 
== OpenBisWiper ==
Takes an input u64 size and a TransferMemory handle. Returns an output [[#IWiper]].
 
= IStorage =
This is "nn::fssrv::sf::IStorage".
 
This is the interface for a raw device, usually a block device.

= IFileSystem =
This is "nn::fssrv::sf::IFileSystem".
 
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.
