Hotplugging them simply doesn't work, so tag them accordingly to avoid users trying and then crashing qemu.
For xhci there is nothing fundamental which prevents hotplug from working, we'll "only" need a exit() function which cleans up everything properly. That isn't for 1.3 though. For ehci+uhci+ohci hotplug can't be supported until qemu gains the capability to hotplug multifunction pci devices. https://bugzilla.redhat.com/show_bug.cgi?id=879096 Signed-off-by: Gerd Hoffmann <[email protected]> --- hw/usb/hcd-ehci-pci.c | 1 + hw/usb/hcd-ohci.c | 1 + hw/usb/hcd-uhci.c | 1 + hw/usb/hcd-xhci.c | 1 + 4 files changed, 4 insertions(+), 0 deletions(-) diff --git a/hw/usb/hcd-ehci-pci.c b/hw/usb/hcd-ehci-pci.c index 5887eab..41dbb53 100644 --- a/hw/usb/hcd-ehci-pci.c +++ b/hw/usb/hcd-ehci-pci.c @@ -123,6 +123,7 @@ static void ehci_class_init(ObjectClass *klass, void *data) k->revision = i->revision; k->class_id = PCI_CLASS_SERIAL_USB; k->config_write = usb_ehci_pci_write_config; + k->no_hotplug = 1; dc->vmsd = &vmstate_ehci_pci; dc->props = ehci_pci_properties; } diff --git a/hw/usb/hcd-ohci.c b/hw/usb/hcd-ohci.c index 64de906..e16a2ec 100644 --- a/hw/usb/hcd-ohci.c +++ b/hw/usb/hcd-ohci.c @@ -1882,6 +1882,7 @@ static void ohci_pci_class_init(ObjectClass *klass, void *data) k->vendor_id = PCI_VENDOR_ID_APPLE; k->device_id = PCI_DEVICE_ID_APPLE_IPID_USB; k->class_id = PCI_CLASS_SERIAL_USB; + k->no_hotplug = 1; dc->desc = "Apple USB Controller"; dc->props = ohci_pci_properties; } diff --git a/hw/usb/hcd-uhci.c b/hw/usb/hcd-uhci.c index 8e47803..d053791 100644 --- a/hw/usb/hcd-uhci.c +++ b/hw/usb/hcd-uhci.c @@ -1327,6 +1327,7 @@ static void uhci_class_init(ObjectClass *klass, void *data) k->device_id = info->device_id; k->revision = info->revision; k->class_id = PCI_CLASS_SERIAL_USB; + k->no_hotplug = 1; dc->vmsd = &vmstate_uhci; dc->props = uhci_properties; u->info = *info; diff --git a/hw/usb/hcd-xhci.c b/hw/usb/hcd-xhci.c index 8ef4b07..efb509e 100644 --- a/hw/usb/hcd-xhci.c +++ b/hw/usb/hcd-xhci.c @@ -3167,6 +3167,7 @@ static void xhci_class_init(ObjectClass *klass, void *data) k->class_id = PCI_CLASS_SERIAL_USB; k->revision = 0x03; k->is_express = 1; + k->no_hotplug = 1; } static TypeInfo xhci_info = { -- 1.7.1
