# # Industrial I/O subsytem configuration # menuconfig IIO tristate "Industrial I/O support" depends on GENERIC_HARDIRQS help The industrial I/O subsystem provides a unified framework for drivers for many different types of embedded sensors using a number of different physical interfaces (i2c, spi, etc). See Documentation/iio for more information. if IIO config IIO_BUFFER bool "Enable buffer support within IIO" help Provide core support for various buffer based data acquisition methods. if IIO_BUFFER config IIO_KFIFO_BUF select IIO_TRIGGER tristate "Industrial I/O buffering based on kfifo" help A simple fifo based on kfifo. Use this if you want a fifo rather than a ring buffer. Note that this currently provides no buffer events so it is up to userspace to work out how often to read from the buffer. endif # IIO_BUFFER config IIO_TRIGGER boolean "Enable triggered sampling support" help Provides IIO core support for triggers. Currently these are used to initialize capture of samples to push into ring buffers. The triggers are effectively a 'capture data now' interrupt. config IIO_CONSUMERS_PER_TRIGGER int "Maximum number of consumers per trigger" depends on IIO_TRIGGER default "2" help This value controls the maximum number of consumers that a given trigger may handle. Default is 2. source "drivers/iio/amplifiers/Kconfig" endif # IIO
