2 # Industrial I/O subsytem 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
25 tristate "Industrial I/O buffering based on kfifo"
27 A simple fifo based on kfifo. Use this if you want a fifo
28 rather than a ring buffer. Note that this currently provides
29 no buffer events so it is up to userspace to work out how
30 often to read from the buffer.
32 config IIO_TRIGGERED_BUFFER
37 Provides helper functions for setting up triggered buffers.
42 boolean "Enable triggered sampling support"
44 Provides IIO core support for triggers. Currently these
45 are used to initialize capture of samples to push into
46 ring buffers. The triggers are effectively a 'capture
49 config IIO_CONSUMERS_PER_TRIGGER
50 int "Maximum number of consumers per trigger"
51 depends on IIO_TRIGGER
54 This value controls the maximum number of consumers that a
55 given trigger may handle. Default is 2.
