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. This patch removes it, instead putting the link pointers into the PCIHostState structure, which have a 1:1 relationship to PCIHostBus structures anyway.

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().

For some reason we recurse to fire the INTx routing notifier for each child of a bus, for each possible device of a bus. That means that if we add a root port, the notifier gets called for that bridge 256 times. If we add an upstream switch behind that root port, 256^2. But of course we need a downstream switch, 256^3.

Each PCI Bridge has a set of implied VGA regions that are enabled when the VGA bit is set in the bridge control register. This allows VGA devices behind bridges. Unfortunately with VGA Enable, which we formerly allowed but didn't back, comes along some required VGA baggage. VGA Palette Snooping is required, along with VGA 16-bit decoding. We don't yet have support for palette snooping. We also don't have support for 10-bit VGA aliases, the default mode, but we enable the register, even on root ports, to avoid confusing guests. Fortunately there's likely nothing from this century that requires these features, so the missing bits are noted with TODOs.

Since 39bffca2 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.
