| 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. |

| bool "Intra-OS shortcut with dibs loopback" |
| depends on DIBS |
| default n |
| 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. |
