- menuconfig MAILBOX
- bool "Mailbox Hardware Support"
- help
- 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.
- if MAILBOX
- config ARM_MHU
- tristate "ARM MHU Mailbox"
- depends on ARM_AMBA
- help
- 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.
- config PL320_MBOX
- bool "ARM PL320 Mailbox"
- depends on ARM_AMBA
- help
- 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.
- config OMAP2PLUS_MBOX
- tristate "OMAP2+ Mailbox framework support"
- depends on ARCH_OMAP2PLUS
- help
- 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
- want to use OMAP2+ Mailbox framework support.
- config OMAP_MBOX_KFIFO_SIZE
- int "Mailbox kfifo default buffer size (bytes)"
- depends on OMAP2PLUS_MBOX
- default 256
- 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).
- config PCC
- bool "Platform Communication Channel Driver"
- depends on ACPI
- default n
- 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.
- config ALTERA_MBOX
- tristate "Altera Mailbox"
- depends on HAS_IOMEM
- help
- An implementation of the Altera Mailbox soft core. It is used
- to send message between processors. Say Y here if you want to use the
- Altera mailbox support.
- config BCM2835_MBOX
- tristate "BCM2835 Mailbox"
- depends on ARCH_BCM2835
- help
- An implementation of the BCM2385 Mailbox. It is used to invoke
- the services of the Videocore. Say Y here if you want to use the
- BCM2835 Mailbox.
- config STI_MBOX
- tristate "STI Mailbox framework support"
- depends on ARCH_STI && OF
- help
- Mailbox implementation for STMicroelectonics family chips with
- hardware for interprocessor communication.
- config MAILBOX_TEST
- tristate "Mailbox Test Client"
- depends on OF
- help
- Test client to help with testing new Controller driver
- implementations.
