termination of all Xenomai threads running in user-space, waiting for them to exit for at most grace-seconds if specified, or indefinitely otherwise.

active RTDM drivers are notified of the transition to the stopped state.

termination of lingering RTDM threads (i.e. running in kernel space), waiting for them to exit for at most 3 seconds.

deactivation of the real-time timing services, control of the hardware timer on all real-time CPUs is fully released to the host kernel.

activation of the real-time timing services, the Cobalt core takes full control over the hardware timer on all real-time CPUs.

loaded RTDM drivers are notified of the transition to the running state.

disabled denotes a fully inoperative core. This state cannot be reached using the corectl command, but only by passing the xenomai.state=disabled option on the kernel command line. A disabled core cannot be started dynamically using corectl.

stopped means that no further connection request will be accepted from applications, the real-time services are currently unavailable. The Cobalt core can be stopped at boot time by passing the xenomai.state=stopped option on the kernel command line. A stopped core can be started dynamically using corectl --start, switching it to the running state.

running denotes an active state of the real-time core, application requests are processed normally. This is the default state entered at boot time, which corresponds to passing the xenomai.state=enabled option on the kernel command line.

teardown denotes a real-time system in the process of stopping all services. This transient status should not be seen unless some threads are unexpectedly lingering despite a termination request was issued.

warmup denotes a real-time system in the process of starting all services. This transient status should not be seen unless an RTDM driver gets stuck while switching to active mode.
