2010-11-21vgabios update: handle compatibility with older qemu versionsGerd Hoffmann
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>
2010-11-21virtfs: enable MSI-XGerd Hoffmann
This patch enables MSI-X for virtfs-9p-pci. It also adds a compat property to pc-0.13 which turns it of there to stay compatible to 0.13-stable. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-08-24Rearrange block headersBlue Swirl
Changing block.h or blockdev.h resulted in recompiling most objects. Move DriveInfo typedef and BlockInterfaceType enum definitions to qemu-common.h and rearrange blockdev.h use to decrease churn. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-07-22virtio-serial: Fix compat property nameAmit Shah
Starting with qemu -M pc-0.12 -device virtio-serial results in -device virtio-serial: Property 'virtio-serial-pci.max_nr_ports' not found The property name 'max_ports' is incorrectly named 'max_nr_ports'. Fix that. Also fix the ppc440 machine type bamboo-0.12 which has this typo. Reported-by: Daniel P.

2010-07-02pc: Fix CMOS info for drives defined with -deviceMarkus Armbruster
Drives defined with -drive if=ide get get created along with the IDE controller, inside machine->init(). That's before cmos_init(). Drives defined with -device get created during generic device init. That's after cmos_init(). Because of that, CMOS has no information on them (type, geometry, translation). Older versions of Windows such as XP reportedly choke on that. Split off the part of CMOS initialization that needs to know about -device devices, and turn it into a reset handler, so it runs after device creation.

System architecture dictates whether HAS_AUDIO is defined. It's then useless to check for HAS_AUDIO in files which are only used on those architectures which always have audio. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
