From 6abfee773fa9696fc7556da0bf78cd153080cb3d Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Tue, 22 Feb 2011 12:28:19 -0500 Subject: linux-yocto: enable audio for selected qemu targets Fixes [BUGID #488 #734] Enable audio for qemux86/qemux86-64 via the following kernel configuration options. CONFIG_SOUND_OSS_CORE=y CONFIG_SOUND_OSS_CORE_PRECLAIM=y CONFIG_SND_RAWMIDI=m CONFIG_SND_SEQUENCER=y CONFIG_SND_OSSEMUL=y CONFIG_SND_MIXER_OSS=y CONFIG_SND_PCM_OSS=y CONFIG_SND_PCM_OSS_PLUGINS=y CONFIG_SND_SEQUENCER_OSS=y CONFIG_SND_RAWMIDI_SEQ=m CONFIG_SND_AC97_CODEC=m CONFIG_SND_ENS1370=m CONFIG_SND_INTEL8X0=m CONFIG_AC97_BUS=m The mechanism to trigger these options is in the form of an optional kernel feature that is only appended for qemux86 and qemux86-64, but is contained within the kernel tree. This allows several things: - the options to be available/shared for all boards - the options to be in tree - to not add the options to every board, which unecessarily bloats the default configuration.
