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

Say Y here if you want to build the ARM MHU controller driver.
|
|
The controller has 3 mailbox channels, the last of which can be
|
|
used in Secure mode only.

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

|
|
Mailbox implementation for OMAP family chips with hardware for
|
|
interprocessor communication involving DSP, IVA1.0 and IVA2 in
|
|
OMAP2/3; or IPU, IVA HD and DSP in OMAP4/5. Say Y here if you

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

help
|
|
ACPI 5.0+ spec defines a generic mode of communication
|
|
between the OS and a platform such as the BMC. This medium
|
|
(PCC) is typically used by CPPC (ACPI CPU Performance management),
|
|
RAS (ACPI reliability protocol) and MPST (ACPI Memory power
|
|
states). Select this driver if your platform implements the
|
|
PCC clients mentioned above.
