| help |
| Size of stack used by work queue RX thread. This work queue is |
| created in the multi-instance / multi-core RPMsg backend module to |
| prevent notifying service users about received data from the system |
| work queue. Size is the same for all instances. |

| bool "Reset shared memory state" |
| help |
| Some platforms retain the memory content upon reset. This is |
| problematic because the backend expects a zero-ed memory to be |
| able to correctly setup instances and endpoints at init time. |
| When this parameter is set to 'y' the status region of the shared |
| memory is reset on kernel initialization. |

| help |
| Maximal number of endpoints that can be registered for one instance |
| for RPMSG backend. |
