Please note this ring buffer implementation is very much a work in progress (and hence RFC). In it's current form it is stable and reasonably efficient. There are a couple of unlikely cases that will lead to more data being lost that is strictly necessary. The target was for the case of requiring regular sampling even during user space reads. All comments welcome. The intention is to make this only one of several implementations with run time selection. For now there is only one, so it is hard coded into the drivers using it.

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

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
