Updated with the changes from the Gerrit CL 40406246 (VSOCK routing). |
Enables netsim to act as the cellular modem simulator for Cuttlefish by passing VSOCK connections directly to netsimd:
1. CLI & Instance Configuration:
- Adds '--netsim_modem' flag to launch_cvd to route cellular modem traffic to netsim.
- Disables the legacy standalone modem_simulator process when '--netsim_modem' or '--netsim' is active.
- Records modem simulator instance count and SIM type in CuttlefishConfig.
2. VSOCK Server Routing ('netsim_server.cpp'):
- Creates a VSOCK server socket ('SharedFD::VsockServer') listening on each guest modem simulator port.
- Configures the CELLULAR chip in netsimd's startup JSON ('-s'), passing the inherited listening file descriptor as 'vsockFd' and the SIM configuration as 'simType'.
Refactored netsim radio enabling to use per-instance config checks in netsim_server.cpp to support mixed-mode multi-instance clusters, and removed the global netsim_radio_enabled config.
