Subject: [alsa-devel] [PATCH v2 0/5] ALSA: hda - Add DP-MST support for NVIDIA codecs
Date: Fri, 15 Nov 2019 15:26:01 +0530 [thread overview]
Message-ID: <20191115095606.22392-1-nmahale@nvidia.com> (raw)
Today, DisplayPort multi-stream transport (DP-MST) audio is not
supported on codec drivers which don't use the audio component
(acomp) binding.
The commit ade49db337a9 (ALSA: hda/hdmi - Allow audio component for
AMD/ATI and Nvidia HDMI) added the DRM audio component binding for
the NVIDIA codec drivers, but the traditional HD-audio unsolicited
event code path is still in use by the proprietary NVIDIA graphics
driver.
This patch set adds DP-MST audio support for non-acomp codec drivers
which use the traditional HD-audio unsolicited event code path. This
patch set adds DP-MST support for NVIDIA codecs.
The patch set has been tested for HDMI/DP-SST/DP-MST(4 dp-mst audio
streams) configurations on NVIDIA Kepler and Maxwell GPUs, using
both the nouveau driver and the proprietary NVIDIA graphics driver.

ALSA: hda - Add DP-MST jack support
ALSA: hda - Add DP-MST conn list support
ALSA: hda - Add DP-MST support for non-acomp codecs
ALSA: hda - Add DP-MST support for NVIDIA codecs
