2 # Industrial I/O subsystem configuration
6 tristate "Industrial I/O support"
7 depends on GENERIC_HARDIRQS
9 The industrial I/O subsystem provides a unified framework for
10 drivers for many different types of embedded sensors using a
11 number of different physical interfaces (i2c, spi, etc).
16 bool "Enable buffer support within IIO"
18 Provide core support for various buffer based data
24 boolean "IIO callback buffer used for push in-kernel interfaces"
26 Should be selected by any drivers that do-inkernel push
27 usage. That is, those where the data is pushed to the consumer.
31 tristate "Industrial I/O buffering based on kfifo"
33 A simple fifo based on kfifo. Use this if you want a fifo
34 rather than a ring buffer. Note that this currently provides
35 no buffer events so it is up to userspace to work out how
36 often to read from the buffer.
38 config IIO_TRIGGERED_BUFFER
43 Provides helper functions for setting up triggered buffers.
48 boolean "Enable triggered sampling support"
50 Provides IIO core support for triggers. Currently these
51 are used to initialize capture of samples to push into
52 ring buffers. The triggers are effectively a 'capture
55 config IIO_CONSUMERS_PER_TRIGGER
56 int "Maximum number of consumers per trigger"
57 depends on IIO_TRIGGER
60 This value controls the maximum number of consumers that a
61 given trigger may handle. Default is 2.
