      conf: aggregate multiple devices on a slot when assigning PCI addresses · 48d39cf9
      Laine Stump 提交于
      If a PCI device has VIR_PCI_CONNECT_AGGREGATE_SLOT set in its
      pciConnectFlags, then during address assignment we allow multiple
      instances of this type of device to be auto-assigned to multiple
      functions on the same device. A slot is used for aggregating multiple
      devices only if the first device assigned to that slot had
      VIR_PCI_CONNECT_AGGREGATE_SLOT set. but any device types that have
      AGGREGATE_SLOT set might be mix/matched on the same slot.
      
      (NB: libvirt should never set the AGGREGATE_SLOT flag for a device
      type that might need to be hotplugged. Currently it is only planned
      for pcie-root-port and possibly other PCI controller types, and none
      of those are hotpluggable anyway)
      
      There aren't yet any devices that use this flag. That will be in a
      later patch.

      qemu: use virDomainPCIAddressSetAllMulti() to set multi when needed · 8f400871
      Laine Stump 提交于
      If there are multiple devices assigned to the different functions of a
      single PCI slot, they will not work properly if the device at function
      0 doesn't have its "multi" attribute turned on, so it makes sense for
      libvirt to turn it on during PCI address assignment. Setting multi
      then assures that the new setting is stored in the config (so it will
      be used next time the domain is started), preventing any potential
      problems in the case that a future change in the configuration
      eliminates the devices on all non-0 functions (multi will still be set
      for function 0 even though it is the only function in use on the slot,
      which has no useful purpose, but also doesn't cause any problems).
      
      (NB: If we were to instead just decide on the setting for
      multifunction at runtime, a later removal of the non-0 functions of a
      slot would result in a silent change in the guest ABI for the
      remaining device on function 0 (although it may seem like an
      inconsequential guest ABI change, it *is* a guest ABI change to turn
      off the multi bit).)

      conf: new function virDomainPCIAddressSetAllMulti() · 3c1a0fc2
      Laine Stump 提交于
      This utility function iterates through all devices looking for any
      with a PCI address that has function != 0 (which implies that multiple
      functions are in use on that slot), then uses an inner iterator to
      find the device that's on function 0 of that same slot and sets the
      "multi" in its virDomainDeviceInfo (as long as it hasn't already been
      set explicitly by someone who presumably has better information than
      we do).
      
      It isn't yet called from anywhere, so will have no functional effect.

      conf: start search for next unused PCI address at same slot as previous find · 66e0b08d
      Laine Stump 提交于
      There is a very slight time advantage to beginning the search for the
      next unused PCI address at the slot *after* the previous find (which
      is now used), but if we do that, we will miss allocating the other
      functions of the same slot (when we implement a
      VIR_PCI_CONNECT_AGGREGATE_SLOT flag to support that).

      conf: eliminate repetitive code in virDomainPCIAddressGetNextSlot() · 99bf66f3
      Laine Stump 提交于
      virDomainPCIAddressGetNextSlot() starts searching from the last
      allocated address and goes to the end of all the buses, then goes back
      to the first bus and searches from there up to the starting point (in
      case any address has been freed since the last time an address was
      allocated. The loops for these two are almost, but not exactly, the
      same, so they have remained as separate loops with the same code
      inside the loop. To lessen maintenance headaches, the identical code
      has been moved out into the function
      virDomainPCIAddressFindUnusedFunctionOnBus(), which is called in place
      of the loop contents.

      conf: eliminate concept of "reserveEntireSlot" · 9ff9d9f5
      Laine Stump 提交于
      setting reserveEntireSlot really accomplishes nothing - instead of
      going to the trouble of computing the value for reserveEntireSlot and
      then possibly setting *all* functions of the slot as in-use, we can
      just set the in-use bit only for the specific function being used by a
      device.  Later we will know from the context (the PCI connect flags,
      and whether we are reserving a specific address or asking for "the
      next available") whether or not it is okay to allocate other functions
      on the same slot.
      
      Although it's not used yet, we allow specifying "-1" for the function
      number when looking for the "next available slot" - this is going to
      end up meaning "return the lowest available function in the slot, but
      since we currently only provide a function from an otherwise unused
      slot, "-1" ends up meaning "0".

      conf: use struct instead of int for each slot in virDomainPCIAddressBus · 9838cad9
      Laine Stump 提交于
      When keeping track of which functions of which slots are allocated, we
      will need to have more information than just the current bitmap with a
      bit for each function that is currently stored for each slot in a
      virDomainPCIAddressBus. To prepare for adding more per-slot info, this
      patch changes "uint8_t slots" into "virDomainPCIAddressSlot slot", which
      currently has a single member named "functions" that serves the same
      purpose previously served directly by "slots".

      libxl: define a per-domain logger. · a30b08b7
      Cédric Bosdonnat 提交于
      libxl doesn't provide a way to write one log for each domain. Thus
      we need to demux the messages. If our logger doesn't know to which
      domain to attribute a message, then it will write it to the default
      log file.
      
      Starting with Xen 4.9 (commit f9858025 and following), libxl will
      write the domain ID in an easy to grab manner. The logger introduced
      by this commit will use it to demux the libxl log messages.
      
      Thanks to the default log file, this logger will also work with older
      versions of Xen.

      NEWS: Improve building pipeline · be36ea4b
      Andrea Bolognani 提交于
      Currently, building the NEWS file involves using a XSLT stylesheet
      to extract information from the same HTML file that's used on the
      libvirt website.
      
      The process works, but it's quite fiddly in that it requires the
      source HTML to be formatted in a very precise way, and a single
      missing newline can mess up the resulting plain text considerably.
      
      Moreover, the XSLT stylesheet itself encodes a lot of the details
      of converting to plain text in a way that's not necessarily easy
      to understand, tweak or fix.
      
      To improve the process, move all existing entries to a new XML
      file that contains exactly the information we care about in a
      simple structured format, and start generating both the HTML and
      plain text versions of the release notes using XSLT stylesheets
      that can now afford to be almost trivial.

      There are still some systems out there that have broken
