From d61a4ce8f01ac9f1810380e043db467d536eeb6b Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Mon, 1 Nov 2010 13:05:32 +0100 Subject: [PATCH] Add Intel HD Audio support to qemu. This patch adds three devices to qemu: intel-hda Intel HD Audio Controller, the PCI device. Provides a HDA bus. Emulates ICH6 at the moment. Adding a ICH9 PCIE variant shouldn't be hard. hda-duplex HDA Codec. Attaches to the HDA bus. Supports 16bit stereo, rates 16k -> 96k, playback, recording and volume control (with CONFIG_MIXEMU=y). hda-output HDA Codec without recording support. Subset of the hda-duplex codec. Use this if you don't want your guests access your mic. Usage: add '-device intel-hda -device hda-duplex' to your command line. Tested guests: * Linux works. * Win7 works. * DOS (mpxplay) works. * WinXP doesn't work. [ v2 changes ] * Fixed endianess, big endian hosts work now. * Fixed some emulation bugs. * Added immediate command emulation. * Added vmstate support. * Make it behave like all other sound card drivers: - can be configured via '--audio-card-list=hda' - can be added to a VM using '-soundhw hda' * Code style fixups. * Zapped guest-triggerable asserts. * Handle partial reads/writes of audio data correctly.
