When a service is registered, [[SVC|svcCreatePort]] is used without a port-name. This means that the port is inaccessible via the port SVCs outside of sm-module. See below for getting a session handle for sending commands to services.
When a service is registered, [[SVC|svcCreatePort]] is used without a port-name. This means that the port is inaccessible via the port SVCs outside of sm-module. See below for getting a session handle for sending commands to services.
Processes with PID less than or equal to the number of NATIVE_FIRM built-in modules (fs, sm, pm, pxi, ldr) have access to all services. This value is obtained from [[SVC|svcGetSystemInfo]].
Processes with PID less than or equal to the number of NATIVE_FIRM built-in modules (fs, sm, pm, pxi, ldr) have access to all services. This value is obtained from [[SVC|svcGetSystemInfo]]. Other processes are limited to access services listed in their [[NCCH/Extended_Header#ARM11_Local_System_Capabilities|service access control list]], as passed to [[SRVPM:RegisterProcess]].
Attempting to use [[SRV:GetServiceSession|GetServiceSession]] with a service that the process has access to when that service isn't registered, results in [[SVC|svcSendSyncRequest]] never returning(the exact cause is unknown).
Attempting to use [[SRV:GetServiceHandle|GetServiceHandle]] with a service that the process has access to when that service isn't registered will block until it is registered.

It appears these "port" commands can be used for transferring arbitrary handles, however [[SRV:GetPort|GetPort]] still uses the same service-access-control validation as [[SRV:GetServiceHandle|GetServiceHandle]]. Despite this fact, it appears that a "port" and a service with the same name can coexist independently.
