   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).

  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.

  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.
