2010-11-21vgabios update: handle compatibility with older qemu versionsGerd Hoffmann3-0/+26
As pointed out by avi the vgabios update is guest-visible and thus has migration implications. One change is that the vga has a valid pci rom bar now. We already have a pci bus property to enable/disable the rom bar and we'll load the bios via fw_cfg as fallback for the no-rom-bar case. So we just have to add compat properties to handle this case. A second change is that the magic bochs lfb @ 0xe0000000 is gone. When live-migrating a guest from a older qemu version it might be using the lfb though, so we have to keep it for the old machine types. The patch enables the bochs lfb in case we don't have the pci rom bar enabled (i.e. we are in 0.13+older compat mode). This patch depends on these patches which add (and use) the pc-0.13 machine type: http://patchwork.ozlabs.org/patch/70797/ http://patchwork.ozlabs.org/patch/70798/ Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Cc: avi@redhat.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-11-16PCI: Bus number from the bridge, not the deviceAlex Williamson1-2/+1
pcibus_dev_print() was erroneously retrieving the device bus number from the secondary bus number offset of the device instead of the bridge above the device. This ends of landing in the 2nd byte of the 3rd BAR for devices, which thankfully is usually zero. Note: pcibus_get_dev_path() copied this code, inheriting the same bug. pcibus_get_dev_path() is used for ramblock naming, so changing it can effect migration. However, I've only seen this byte be non-zero for an assigned device, which can't migrate anyway, so hopefully we won't run into any issues. This patch does not touch pcibus_get_dev_path, as bus number is guest assigned for nested buses, so using it for migration is broken anyway. Fix it properly later.

2010-11-01Add Intel HD Audio support to qemu.Gerd Hoffmann5-0/+2933
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.
