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