This patch series adds support for Xen [1] para-virtualized
sound frontend driver. It implements the protocol from
include/xen/interface/io/sndif.h with the following limitations:
- mute/unmute is not supported
- get/set volume is not supported
Volume control is not supported for the reason that most of the
use-cases (at the moment) are based on scenarious where
unprivileged OS (e.g. Android, AGL etc) use software mixers.

Both capture and playback are supported.

Thank you,

This patchset is not proper yet.

really sorry for the mess :(
Your first patch includes code difference under line 26, thus it expects existence of a file 'sound/drivers/xen-front.c' in tree. However, the file is not introduced in any upstream yet; at least, Linus's tree and Iwai-san's tree.
I missed the very first patch in the series, this is why, my bad

You still work on your local branch, not for us.
