I finally pull requested initial Linux kernel SDR API, after many many review rounds! It will go mainline Kernel 3.15 as it is just a little bit too late for 3.14... Now it is time to design needed controls. I started already from the tuner gain controls, as you likely saw from the picture above. Now there is own controls for LNA, Mixer and RF gain.
I uploaded to GitHub some related software for test. Patches are more than welcome!
Will the Linux be first OS having native SDR support :)
