== OpenCodeFileSystem ==
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.

|-
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.

== OpenFileSystem ==
== SimulateDeviceDetectionEvent ==
Takes a type-0x19 input [[#ContentPath]] and a [[#FileSystemProxyType]] as parameters. Returns an [[#IFileSystem]].
Takes a total of 0xC-bytes of input, no output.


[2.0.0+] This function was removed.
== VerifySaveDataFileSystem ==
Takes an unknown input u64 and a type-0x6 output buffer.


== SetCurrentProcess ==
The input u64 high-byte must be non-zero, otherwise an [[Error_codes|error]] is returned(0xE02).
Takes a pid-descriptor.


== OpenFileSystemWithPatch ==
== GetSaveDataCommitId ==
Takes an input [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
Takes an input u8 and u64, returns an output u64.


Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].
== SetSdCardEncryptionSeed ==
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.


Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.
[[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.


== OpenFileSystemWithId ==
== OpenAccessFailureDetectionEventNotifier ==
Takes a type-0x19 input buffer, an [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
Takes 8-bytes of input and returns an [[#IEventNotifier]].


The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
[8.0.0+] Now takes an additional 8-bytes of input.


The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
== SetSaveDataSize ==
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.


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.
These variables are normally initialized with 32 MiB (0x2000000) and 16 MiB (0x1000000), respectively.


The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.
These variables don't seem to be actually used anywhere else (?)


After the [[#FileSystemProxyType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
== SetSaveDataRootPath ==
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);


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.
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.


== OpenBisFileSystem ==
== SetGlobalAccessLogMode ==
Takes a type-0x19 input buffer string and a [[#BisPartitionId]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].
Takes an input u32.


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 ==
== GetGlobalAccessLogMode ==
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.
Returns an output u32.


== InvalidateBisCache ==
GlobalAccessLogMode is normally 0.
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].


== DeleteSaveDataFileSystem ==
== OutputAccessLogToSdCard ==
Takes an input u64.
Takes a type-0x5 input buffer.


== CreateSaveDataFileSystem ==
The input buffer is the string to output to the log. User-processes normally include a newline at the end.
Takes a 0x40-byte [[#SaveDataAttribute]], a 0x40-byte [[#SaveDataCreationInfo]], and a 0x10-byte input struct which governs creation of a saveMeta file.


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


Creates non-system savedata.
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.


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


Creates savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.
== GetProgramIndexForAccessLog ==
No input, returns two 32-bit values "version" and "program_index".


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


== OpenGameCardFileSystem ==
== OpenBisWiper ==
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].
Takes an input u64 size and a TransferMemory handle. Returns an output [[#IWiper]].


Mounts a [[Gamecard_Partition|gamecard partition]].
= IStorage =
This is "nn::fssrv::sf::IStorage".


== CreateSaveDataFileSystemWithHashSalt ==
This is the interface for a raw device, usually a block device.
Takes a total of 0xB0-bytes of input, no output.


== OpenSaveDataFileSystem ==
{| class="wikitable" border="1"
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]].
== GetSize ==
Returns a size.


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


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


Mounts SaveData as ReadOnly.
* '''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.


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


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


== OpenSaveDataInfoReader ==
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
No input, 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.


== OpenSaveDataInfoReaderBySaveDataSpaceId ==

== OpenSaveDataTransferManagerVersion2 ==
* When bit 0 is set, the file is Readable: you can use the Read operation.
No input, returns an [[#ISaveDataTransferManagerWithDivision]].
* 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)

== SetSdCardEncryptionSeed ==
== ReadSaveDataInfo ==
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.
Takes a type-0x6 output buffer. Returns an output u64 for total output entries. This buffer contains an array of [[#SaveDataInfo]].


[[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.
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).


== OpenAccessFailureDetectionEventNotifier ==
= IDeviceOperator =
Takes 8-bytes of input and returns an [[#IEventNotifier]].
This is "nn::fssrv::sf::IDeviceOperator".


[8.0.0+] Now takes an additional 8-bytes of input.

! Cmd || Name
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.
|-

| 3 || [2.0.0+] [[#GetSdCardUserAreaSize]]
 
|-
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.
| 4 || [2.0.0+] [[#GetSdCardProtectedAreaSize]]

== SetGlobalAccessLogMode ==
|-
Takes an input u32.
| 7 || [20.0.0+] SetSdCardActivationMode
 
== GetGlobalAccessLogMode ==
Returns an output u32.
 
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.
