| help | |
| Direct Internal Buffer Sharing (DIBS) is a communication method that | |
| uses common physical (internal) memory for synchronous direct access | |
| into a remote buffer. | |
| Select this option to provide the abstraction layer between | |
| dibs devices and dibs clients like the SMC protocol. | |
| The module name is dibs. | |

| help | |
| DIBS_LO enables the creation of an software-emulated dibs device | |
| named lo which can be used for transferring data when communication | |
| occurs within the same OS. This helps in convenient testing of | |
| dibs clients, since dibs loopback is independent of architecture or | |
| hardware. |
