Support for OMAP's remote processors (dual M3
and DSP on OMAP4) via the remote processor framework.
Currently only supported on OMAP4.
It gets selected by DSP or IPU OMAP_REMOTEPROC instances,
in order to enable multimedia use-cases to run on your platform
(multimedia codecs are offloaded to remote DSP processors using
this framework).
config OMAP_REMOTEPROC_IPU
bool "OMAP remoteproc support for IPU"
help
Say Y here if you want to enable OMAP's IPU remote processor.
This option controls only the dual M3 processor sub-system. You
would want to say y here usually, as this is the sub-system where
typically video & imaging codec control s/w is offloaded.
It's safe to say n here if you're not interested in multimedia
offloading (by IPU) or just want a bare minimum kernel.
config OMAP_REMOTEPROC_DSP
bool "OMAP remoteproc support for DSP"
help
Say Y here if you want to enable OMAP's DSP remote processor.
This option controls only the DSP processor sub-system. DSP would
typically be used to offload audio codecs or other advanced
processing algorithms.
It's safe to say n here if you're not interested in offloading
audio or any other algorithm (by DSP) or just want a bare minimum kernel.
config OMAP_REMOTEPROC_WATCHDOG
bool "OMAP remoteproc watchdog timer"
depends on OMAP_REMOTEPROC
default y
help
Say Y here to enable watchdog timer for remote processors.
This option controls the watchdog functionality for the remote
processors in OMAP. Dedicated timers are used by the remote
processors and triggers the timer interrupt upon a watchdog
detection.
# Amount of CMA memory to reserve for OMAP's remoteproc sub-system.
# We need quite much. Fortunately, CMA makes sure this memory isn't
# wasted in case we're not loading the remote processors.
config OMAP4_IPU_CMA_SIZE
hex "Cortex M3 physically contiguous memory pool size (in bytes)"
depends on OMAP_REMOTEPROC_IPU
default 0x6800000
help
Allocate a specified size of physically contiguous memory (CMA)
for OMAP4's dual Cortex-M3 sub-system. Vast majority of this
memory isn't wasted in case the M3 sub-system isn't loaded.
config OMAP5_IPU_CMA_SIZE
hex "Cortex M4 physically contiguous memory pool size (in bytes)"
depends on OMAP_REMOTEPROC_IPU
default 0xA400000
help
Allocate a specified size of physically contiguous memory (CMA)
for OMAP's dual M4 sub-system. Vast majority of this
memory isn't wasted in case the M4 sub-system isn't loaded.
config OMAP_DSP_CMA_SIZE
hex "Dsp physically contiguous memory pool size (in bytes)"
depends on OMAP_REMOTEPROC_DSP
default 0x500000
help
Allocate a specified size of physically contiguous memory (CMA)
for OMAP's dsp sub-system. Vast majority of this
memory isn't wasted in case the Dsp sub-system isn't loaded.
