Services are system processes running in the background which wait for incoming requests. When a process wants to communicate with a service, it first needs to get a handle to the named service, and then it can communicate with the service via inter-process communication (each service has a name up to 8 characters).

Handles for services are retrieved from the service manager port, "sm:". Manager service "sm:m" also exists. Services are an abstraction of ports, they operate the same way except regular ports can have their handles retrieved directly from a SVC.

Handles for services are retrieved from the service manager port, "sm:", and are released via svcCloseHandle or when a process is terminated or crashes. Manager service "sm:m" also exists. Services are an abstraction of ports, they operate the same way except regular ports can have their handles retrieved directly from a SVC. Services are also able to limit the number of handles given to other processes.

Services are system processes running in the background which wait for incoming requests. When a process wants to communicate with a service, it first needs to get a handle to the named service, and then it can communicate with the service via inter-process communication (each service has a name up to 8 characters).

Handles for services are retrieved from the service manager port, "sm:", and are released via svcCloseHandle or when a process is terminated or crashes. Manager service "sm:m" also exists. Services are an abstraction of ports, they operate the same way except regular ports can have their handles retrieved directly from a SVC. Services are also able to limit the number of handles given to other processes.

sm:

This is "nn::sm::detail::IUserInterface".

Cmd Name
0 #RegisterClient
1 #GetServiceHandle
2 #RegisterService
3 #UnregisterService
4 [11.0.0-11.0.1] #DetachClient

RegisterClient

Takes a PID-descriptor and a reserved input u64.

GetServiceHandle

Takes a zero-padded service name encoded as an u64 integer. Returns a handle.

RegisterService

Takes a zero-padded service name encoded as an u64 integer, an u8 bool IsLight, and a s32 MaxSessions at the next word. Returns a handle.

[12.0.0+] This is only available with tipc.

UnregisterService

Takes a zero-padded service name encoded as an u64 integer.

[12.0.0+] This is only available with tipc.

DetachClient

Takes a PID-descriptor and a reserved input u64.

sm:m

This is "nn::sm::detail::IManagerInterface".

Cmd Name
0 #RegisterProcess
1 #UnregisterProcess

RegisterProcess

Takes a PID and two type-0x5 input buffers with the ACID and ACI0 service lists. That data originates from NPDM.

UnregisterProcess

Takes a PID.
