Devices

IDE / AHCI

  • Added emulation layer for an ICH-9 AHCI controller (not yet stable). Tested with Linux, OpenBSD, Windows Vista and Windows 7. The AHCI emulation supports NCQ, so multiple read or write requests can be outstanding at the same time.(commit f6ad2e32f8d833c7f1c75dc084a84a8f02704d64)
    • to use it, use the following command line snippet: -drive id=disk,file=<your image goes here>,if=none -device ahci,id=ahci -device ide-drive,drive=disk,bus=ahci.0

SCSI

  • Various bug fixes, no new features.

PCI/PCI Express

Sound

  • New Intel HD Audio support (commit d61a4ce8f01ac9f1810380e043db467d536eeb6b), adding three new devices:
    • intel-hda: Intel HD Audio Controller, the PCI device.
    • 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.
