[PATCH 00/11] ALSA: vsnd: Add Xen para-virtualized frontend driver

Show all headers | View raw

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

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,
Oleksandr
