2010-11-16tap: make set_offload a nop after netdev cleanupMichael S. Tsirkin1-1/+5
virtio-net expects set_offload to succeed after peer cleanup. Since we don't have an open fd anymore, make it so. Fixes warning about the failure of offload setting. Reported-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-11-16tap: clear vhost_net backend on cleanupMichael S. Tsirkin1-0/+1
Frontends calling tap_get_vhost_net get an invalid pointer after the peer backend has been deleted. Jason Wang <jasowang@redhat.com> reports this leading to a crash in ack_features when we remove the vhost-net bakend of a virtio nic. The fix is simply to clear the backend pointer.

2010-11-16switch stdvga to pci vgabiosGerd Hoffmann1-4/+3
Make stdvga provide the new vgabios binary (with pcibios support) using the PCI option rom bar. Seabios will happily load it from there. The new vga bios will also lookup the framebuffer address in pci config space, so the magic bochs lfb @ 0xe0000000 is not needed any more -> zap it.

2010-11-09spice: add audioGerd Hoffmann6-0/+334
Add support for the spice audio interface. With this patch applied audio can be forwarded over the network from/to the spice client. Both recording and playback is supported. The driver is first in the driver list, but the can_be_default flag is set only in case spice is active. So if you have the spice protocol enabled the spice audio driver is the default one, otherwise whatever comes first after spice in the list. Overriding the default using QEMU_AUDIO_DRV works in any case.

2010-11-01Add Intel HD Audio support to qemu.Gerd Hoffmann8-2/+2946
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.
