Multiple -machine options with the same ID are merged. All but the one without an ID are to be silently ignored. In most places, we query these options with a null ID. This is correct. In some places, we instead query whatever options come first in the list. This is wrong. When the -machine processed first happens to have an ID, options are taken from that ID, and the ones specified without ID are silently ignored. Example: $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=kvm,usb=on QEMU 1.5.50 monitor - type 'help' for more information (qemu) info kvm kvm support: enabled (qemu) info usb (qemu) q $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on QEMU 1.5.50 monitor - type 'help' for more information (qemu) info kvm kvm support: disabled (qemu) info usb (qemu) q $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen QEMU 1.5.50 monitor - type 'help' for more information (qemu) info kvm kvm support: enabled (qemu) info usb USB support not enabled (qemu) q $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error xen be core: can't open xen interface failed to initialize Xen: Operation not permitted Option usb is queried correctly, and the one without an ID wins, regardless of option order. Option accel is queried incorrectly, and which one wins depends on option order and ID. Affected options are accel (and its sugared forms -enable-kvm and -no-kvm), kernel_irqchip, kvm_shadow_mem. Additionally, option kernel_irqchip is normally on by default, except it's off when no -machine options are given. Bug can't bite, because kernel_irqchip is used only when KVM is enabled, KVM is off by default, and enabling always creates -machine options. Downstreams that enable KVM by default do get bitten, though. Use qemu_get_machine_opts() to fix these bugs.

Commit 4f6dd9af changed the initialization of opts in opts_parse() to this: if (defaults) { if (!id && !QTAILQ_EMPTY(&list->head)) { opts = qemu_opts_find(list, NULL); } else { opts = qemu_opts_create(list, id, 0); } } else { opts = qemu_opts_create(list, id, 1); } Same as before for !defaults. If defaults is true, and params has no ID, and options exist, we use the first assignment. It sets opts to null if all options have an ID. opts_parse() then returns null. qemu_opts_set_defaults() asserts the value is non-null. It's the only caller that passes true for defaults. To reproduce, try "-M xenpv -machine id=foo" (yes, "id=foo" is silly, but it shouldn't crash). I believe the function attempts to do the following: If options don't yet exist, create new options Else, if defaults, modify the existing options Else, if list->merge_lists, modify the existing options Else, fail A straightforward call of qemu_opts_create() does exactly that.

With mon:stdio you can exit the VM by switching to the monitor and sending the "quit" command. It is then useful to pass Ctrl-C to the VM instead of exiting. This in turn lets us stop tying the default signal handling behavior to -nographic, removing gratuitous differences between "-display none" and "-nographic". This patch changes behavior for "-display none -serial mon:stdio", as expected, but not for "-display none -serial stdio".

The host_buses list is an odd structure - a list of pointers to PCI root buses existing in parallel to the normal qdev tree structure.

Currently pci_find_primary_bus() searches the list of root buses for one with domain 0. But since host buses are always registered with domain 0, this just amounts to finding the only PCI host bus. The only remaining users of pci_find_primary_bus() are in pci-hotplug-old.c, which implements the old style pci_add/pci_del commands. Therefore, this patch redefines pci_find_primary_bus() to find the only PCI root bus, returning an error if there are multiple roots. The callers in pci-hotplug-old.c are updated correspondingly, to produce sensible error messages. Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NMichael S.

At present, pci_nic_init() and pci_nic_init_nofail() assume that they will only create a NIC under the primary PCI root. As we add support for multiple PCI roots, that may no longer be the case. This patch adds a root bus parameter to pci_nic_init() (and updates callers accordingly) to allow the machine init code using it to specify the right PCI root for NICs created by old-style -net nic parameters. NICs created new-style, with -device can of course be put anywhere. Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

pci_get_bus_devfn() interprets a full PCI address string to give a PCIBus * and device/function number within that bus. Currently it assumes it is working on an address under the primary PCI root bus. This patch extends it to allow the caller to specify a root bus. This might seem a little odd since the supplied address can (theoretically) include a PCI domain number. However, attempting to use a non-zero domain number there is currently an error, so that shouldn't really cause problems.

pci_find_domain() is used in a number of places where we want an id for a whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is that many platforms may support multiple independent host bridges with no hardware supplied notion of domain number. This patch, therefore, replaces calls to pci_find_domain() with calls to a new pci_root_bus_path() returning a string. The new call is implemented in terms of a new callback in the host bridge class, so it can be defined in some way that's well defined for the platform. When no callback is available we fall back on the qbus name. Most current uses of pci_find_domain() are for error or informational messages, so the change in identifiers should be harmless. The exception is pci_get_dev_path(), whose results form part of migration streams. To maintain compatibility with old migration streams, the PIIX PCI host is altered to always supply "0000" for this path, which matches the old domain number (since the code didn't actually support domains other than 0). For the pseries (spapr) PCI bridge we use a different platform-unique identifier (pseries machines can routinely have dozens of PCI host bridges). Theoretically that breaks migration streams, but given that we don't yet have migration support for pseries, it doesn't matter. Any other machines that have working migration support including PCI devices will need to be updated to maintain migration stream compatibility.

Currently pci_find_domain() performs two functions - it locates the PCI root bus above the given bus, then looks up that root bus's domain number. This patch adds a helper function to perform the first task, finding the root bus for a given PCI device. This is then used in pci_find_domain(). This changes pci_find_domain()'s signature slightly, taking a PCIDevice instead of a PCIBus - since all callers passed something of the form dev->bus, this simplifies things slightly.

pci_find_root_bus() takes a domain parameter. Currently PCI root buses with domain other than 0 can't be created, so this is more or less a long winded way of retrieving the main PCI root bus. Numbered domains don't actually properly cover the (non x86) possibilities for multiple PCI root buses, so this patch for now enforces the domain == 0 restriction in other places to replace pci_find_root_bus() with an explicit pci_find_primary_bus().
