3 | help | |
4 | Mailbox is a framework to control hardware communication between | |
5 | on-chip processors through queued messages and interrupt driven | |
6 | signals. Say Y if your platform supports hardware mailboxes. | |

12 | help | |
13 | An implementation of the ARM PL320 Interprocessor Communication | |
14 | Mailbox (IPCM), tailored for the Calxeda Highbank. It is used to | |
15 | send short messages between Highbank's A9 cores and the EnergyCore | |
16 | Management Engine, primarily for cpufreq. Say Y here if you want | |
17 | to use the PL320 IPCM support. | |

50 | Specify the default size of mailbox's kfifo buffers (bytes). | |
51 | This can also be changed at runtime (via the mbox_kfifo_size | |
52 | module parameter). | |
