[Qemu-devel] [PATCH 2/2] ide: implement stub for audio control/volume read |
Date: |
Mon, 30 Nov 2009 17:37:03 -0200 |
This implements the audio control or volume read support as needed by
some systems. A Conectiva Parolin system required this to detect an IDE
device as CD-ROM, through the CDVOLREAD ioctl.
