      pci: Fold host_buses list into PCIHostState functionality · 7588e2b0
      David Gibson authored
      
      
      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.

      pci: Remove domain from PCIHostBus · 2b8cc89a
      David Gibson authored
      
      
      There are now no users of the domain field of PCIHostBus, so remove it
      from the structure, and as a parameter from the pci_host_bus_register()
      function which sets it.

      pci: Simpler implementation of primary PCI bus · 9bc47305
      David Gibson authored
      
      
      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.

      pci: Add root bus parameter to pci_nic_init() · 29b358f9
      David Gibson authored
      
      
      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.

      pci: Add root bus argument to pci_get_bus_devfn() · 85c6e4fa
      David Gibson authored
      
      
      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: Replace pci_find_domain() with more general pci_root_bus_path() · 568f0690
      David Gibson authored
      
      
      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.

      pci: Use helper to find device's root bus in pci_find_domain() · c473d18d
      David Gibson authored
      
      
      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: Abolish pci_find_root_bus() · 1ef7a2a2
      David Gibson authored
      
      
      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().

      Make all static TypeInfos const · 8c43a6f0
      Andreas Färber authored
      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.
