Date: Wed, 20 Jan 2021 01:36:28 +0100 From: Anton Yakovlev <anton.yakovlev@...nsynergy.com> To: <virtualization@...ts.linux-foundation.org>, <alsa-devel@...a-project.org>, <virtio-dev@...ts.oasis-open.org> CC: Jaroslav Kysela <perex@...ex.cz>, Jason Wang <jasowang@...hat.com>, <linux-kernel@...r.kernel.org>, "Michael S. Tsirkin" <mst@...hat.com>, Takashi Iwai <tiwai@...e.com> Subject: [PATCH 0/7] ALSA: add virtio sound driver This series implements a driver part of the virtio sound device specification v8 [1]. The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device. The series is based (and was actually tested) on Linus's master branch [2], on top of commit 1e2a199f6ccd ("Merge tag 'spi-fix-v5.11-rc4' of ...") As a device part was used OpenSynergy proprietary implementation. Any comments are very welcome.
