2 bool "Mailbox Hardware Support"
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.
10 bool "ARM PL320 Mailbox"
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.
20 tristate "OMAP2+ Mailbox framework support"
21 depends on ARCH_OMAP2PLUS
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.
28 config OMAP_MBOX_KFIFO_SIZE
29 int "Mailbox kfifo default buffer size (bytes)"
30 depends on OMAP2PLUS_MBOX
33 Specify the default size of mailbox's kfifo buffers (bytes).
34 This can also be changed at runtime (via the mbox_kfifo_size
