| 2 | bool "Mailbox Hardware Support" | |
| 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. | |

22 | help |
| 23 | Mailbox implementation for OMAP family chips with hardware for | |
| 24 | interprocessor communication involving DSP, IVA1.0 and IVA2 in | |
| 25 | OMAP2/3; or IPU, IVA HD and DSP in OMAP4/5. Say Y here if you | |
| 26 | want to use OMAP2+ Mailbox framework support. | |

| 32 | help | |
| 33 | Specify the default size of mailbox's kfifo buffers (bytes). | |
| 34 | This can also be changed at runtime (via the mbox_kfifo_size | |
| 35 | module parameter). | |

| 37 | config PCC | |
| 38 | bool "Platform Communication Channel Driver" | |
| 39 | depends on ACPI | |
| 40 | help | |
| 41 | ACPI 5.0+ spec defines a generic mode of communication | |
| 42 | between the OS and a platform such as the BMC. This medium | |
| 43 | (PCC) is typically used by CPPC (ACPI CPU Performance management), | |
| 44 | RAS (ACPI reliability protocol) and MPST (ACPI Memory power | |
| 45 | states). Select this driver if your platform implements the | |
| 46 | PCC clients mentioned above. | |

| 50 | help | |
| 51 | An implementation of the Altera Mailbox soft core. It is used | |
| 52 | to send message between processors. Say Y here if you want to use the | |
| 53 | Altera mailbox support. | |
