* vga: tag as not hotplugable.Gerd Hoffmann2011-01-101-0/+1
| | | | | | | | | | This patch tags all vga cards as not hotpluggable. The qemu standard vga will never ever be hotpluggable. For cirrus + vmware it might be possible to get that work some day. Todays we can't handle that for a number of reasons though. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* vgabios update: handle compatibility with older qemu versionsGerd Hoffmann2010-11-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

* switch stdvga to pci vgabiosGerd Hoffmann2010-11-161-4/+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.

* pci: don't overwrite multi functio bit in pci header type.Isaku Yamahata2010-07-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't overwrite pci header type. Otherwise, multi function bit which pci_init_header_type() sets appropriately is lost. Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero which is already zero cleared. how to test: run qemu and issue info pci to see whether a device in question is normal device, not pci-to-pci bridge. This is handy because guest os isn't required. tested changes: The following files are covered by using following commands. sparc64-softmmu apb_pci.c, vga-pci.c, cmd646.c, ne2k_pci.c, sun4u.c ppc-softmmu grackle_pci.c, cmd646.c, ne2k_pci.c, vga-pci.c, macio.c ppc-softmmu -M mac99 unin_pci.c(uni-north, uni-north-agp) ppc64-softmmu pci-ohci, ne2k_pci, vga-pci, unin_pci.c(u3-agp) x86_64-softmmu acpi_piix4.c, ide/piix.c, piix_pci.c -vga vmware vmware_vga.c -watchdog i6300esb wdt_i6300esb.c -usb usb-uhci.c -sound ac97 ac97.c -nic model=rtl8139 rtl8139.c -nic model=pcnet pcnet.c -balloon virtio virtio-pci.c: untested changes: The following changes aren't tested. prep_pci.c: ppc-softmmu -M prep should cover, but core dumped. unin_pci.c(uni-north-pci): the caller is commented out. openpic.c: the caller is commented out in ppc_prep.c Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* Make sure to enable dirty tracking of VBE vram mappingAnthony Liguori2009-12-181-6/+1
| | | | | | | | | | | | | | | Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires that all mappings of the VGA vram have dirty tracking enabled on them. Any access to the VGA vram through the VBE mapping currently fails to result in dirty page tracking updates causing a black screen. This is the true root cause of VMware VGA not working correctly under KVM and likely also an issue with some of the std-vga black screen issues too. Cirrus does not enable VBE so it would not be a problem when using Cirrus. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Rebased-by: Dave Airlie <airlied@redhat.com>

* New qdev_init_nofail()Markus Armbruster2009-10-071-1/+1
| | | | | | | | | | | | | | | | | | | Like qdev_init(), but terminate program via hw_error() instead of returning an error value. Use it instead of qdev_init() where terminating the program on failure is okay, either because it's during machine construction, or because we know that failure can't happen. Because relying in the latter is somewhat unclean, and the former is not always obvious, it would be nice to go back to qdev_init() in the not-so-obvious cases, only with proper error handling. I'm leaving that for another day, because it involves making sure that error values are properly checked by all callers.

* Fix pci_vga_init() not to ignore bus argumentMarkus Armbruster2009-10-051-1/+1
| | | | | | | | | | Commit a414c306 converted all VGA devices to qdev. It used pci_create_simple() for all devices, except for this one it used pci_create(). That's wrong, because it uses PCI bus#0 regardless of the bus argument. Fix by switching to pci_create_noinit().
