tristate "IIO callback buffer used for push in-kernel interfaces"
|
|
help
|
|
Should be selected by any drivers that do in-kernel push
|
|
usage. That is, those where the data is pushed to the consumer.
|

config IIO_BUFFER_DMA
|
|
tristate
|
|
help
|
|
Provides the generic IIO DMA buffer infrastructure that can be used by
|
|
drivers for devices with DMA support to implement the IIO buffer.
|
|
|
|
Should be selected by drivers that want to use the generic DMA buffer
|
|
infrastructure.
|

config IIO_BUFFER_DMAENGINE
|
|
tristate
|
|
select IIO_BUFFER_DMA
|
|
help
|
|
Provides a bonding of the generic IIO DMA buffer infrastructure with the
|
|
DMAengine framework. This can be used by converter drivers with a DMA port
|
|
connected to an external DMA controller which is supported by the
|
|
DMAengine framework.
|
|
|
|
Should be selected by drivers that want to use this functionality.
|

|
|
config IIO_BUFFER_HW_CONSUMER
|
|
tristate "Industrial I/O HW buffering"
|
|
help
|
|
Provides a way to bonding when an IIO device has a direct connection
|
|
to another device in hardware. In this case buffers for data transfers
|
|
are handled by hardware.
|
|
|
|
Should be selected by drivers that want to use the generic Hw consumer
|
|
interface.

config IIO_KFIFO_BUF
|
|
tristate "Industrial I/O buffering based on kfifo"
|
|
help
|
|
A simple fifo based on kfifo. Note that this currently provides
|
|
no buffer events so it is up to userspace to work out how
|
|
often to read from the buffer.
|
|
|
|
config IIO_TRIGGERED_BUFFER

tristate

select IIO_KFIFO_BUF
|
|
help
|
|
Provides helper functions for setting up triggered buffers.
