ALSA: xen-front: Introduce Xen para-virtualized sound frontend driver Introduce skeleton of the para-virtualized Xen sound frontend driver. Initial handling for Xen bus states: implement Xen bus state machine for the frontend driver according to the state diagram and recovery flow from sound para-virtualized protocol: xen/interface/io/sndif.h.

ALSA: xen-front: Read sound driver configuration from Xen store Read configuration values from Xen store according to xen/interface/io/sndif.h protocol: - introduce configuration structures for different components, e.g. sound card, device, stream - read PCM HW parameters, e.g rate, format etc. - detect stream type (capture/playback) - read device and card parameters Signed-off-by: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> 2018-05-14 09:27:38 +03:00			`snd_xen_front-objs := xen_snd_front.o \`
ALSA: xen-front: Implement Xen event channel handling Handle Xen event channels: - create for all configured streams and publish corresponding ring references and event channels in Xen store, so backend can connect - implement event channels interrupt handlers - create and destroy event channels with respect to Xen bus state Signed-off-by: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> 2018-05-14 09:27:39 +03:00			`xen_snd_front_cfg.o \`
ALSA: xen-front: Implement handling of shared buffers Implement shared buffer handling according to the para-virtualized sound device protocol at xen/interface/io/sndif.h: - manage buffer memory - handle granted references - handle page directories [ Fixed missing linux/kernel.h inclusion -- tiwai ] Signed-off-by: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> 2018-05-14 09:27:40 +03:00			`xen_snd_front_evtchnl.o \`
