== OpenCodeFileSystem ==
Takes a type-0x19 input buffer containing a [[#FspPath]] and an input [[NCM_services#ProgramId|ProgramId]]. Returns an [[#IFileSystem]].
[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 ==
Takes an input u64 ProcessId. Returns a bool (1 if the process id's [[#FspPath]] ends in ".nca").
== SetCurrentProcess ==
Takes an input u64 ProcessId. No output.

== RegisterProgram ==
== RegisterProgram ==
Takes a storageID, a pid, a titleID, 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.

[10.0.0+] This was moved to [[Loader_services|Loader]].

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.
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.

When [[#FileSystemType]] is '''ContentMeta''', 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 titleID, then an error is thrown on mismatch.

There are two main implementations of this interface:
There are two main implementations of this interface:


* '''RomFS''': Filesystem implementation statically linked in the binary. Uses an [[#IStorage]] interface as underlying raw device.
* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
* '''IPC proxy''': Used for all non-RomFS filesystems. In this case, actual filesystem implementation is in the FS process.
* '''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.

This is accessed using the same commands for SaveData with the same input u8. The [[#SaveDataAttribute]] is the same as DeviceSaveData (besides the SaveDataType), except that the [[NCM_services#ApplicationId|ApplicationId]] field is always set to <input ApplicationId> (unlike DeviceSaveData where it's optional).

The 0x10-byte struct passed to [[#CreateSaveDataFileSystem]] has the first 0x5-bytes set to all-zero.
 
MountSystemBcatSaveData uses [[#OpenSaveDataFileSystemBySystemSaveDataId]] with [[#SaveDataSpaceId]] System. The [[#SaveDataAttribute]] is all-zero, except for the SaveDataType, and SystemSaveDataId is set to the input param.
