Hello everyone, (Never done this before, let me know if I do anything incorrectly). I am looking for a dummy example on using the iio/buffer-dmaengine I have found several SDR examples in the linux/driver/iio/adc. However I am struggling to implement a simple version of them myself. The main road block I have currently seems to be a different between the AnalogDevicesInc github project and Torvalds. Specifically the difference is in “linux/include/linux/iio/buffer-dmaengine.h”. One takes 2 arguments and the other 4. Along with this when attempting to add a module that uses dmaEngine I get the following dmesg: “Unknown symbol iio_dmaengine_buffer_alloc” Am I missing something stupid? Am I using an obsolete functionality? Should I be using iio/kfifo_buf.h? Thanks everyone, John
