config IIO_BUFFER_CB |
|
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 "Industrial I/O DMA buffer infrastructure" |
|
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 "Industrial I/O DMA buffer integration with DMAEngine" |
|
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 "Industrial I/O triggered buffer support" |
|
select IIO_TRIGGER |
|
select IIO_KFIFO_BUF |
|
help |
|
Provides helper functions for setting up triggered buffers.
