2015-06-23hw/pci-bridge: format special OFW unit address for PXB hostLaszlo Ersek
We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg file should follow the pattern /pci@i0cf8,%x/... for devices that live behind an extra root bus. The extra root bus in question is the %x'th among the extra root buses. (In other words, %x gives the position of the affected extra root bus relative to the other extra root buses, in bus_nr order.) %x starts at 1, and is formatted in hex. The portion of the unit address that comes before the comma is dynamically taken from the main host bridge, similarly to sysbus_get_fw_dev_path().

2015-06-23hw/core: explicit OFW unit address callback for SysBusDeviceClassLaszlo Ersek
The sysbus_get_fw_dev_path() function formats OpenFirmware device path nodes ("driver-name@unit-address") for sysbus devices. The first choice for "unit-address" is the base address of the device's first MMIO region. The second choice is its first IO port. However, if two sysbus devices with the same "driver-name" lack both MMIO and PIO resources, then there is no good way to distinguish them based on their OFW nodes, because in this case unit-address is omitted completely for both devices. An example is TYPE_PXB_HOST ("pxb-host"). For the sake of such devices, introduce the explicit_ofw_unit_address() "virtual member function". With this function, each sysbus device in the same SysBusDeviceClass can state its own address. Cc: Markus Armbruster <armbru@redhat.com> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

2015-06-23hw/pci-bridge: disable SHPC in PXBLaszlo Ersek
OVMF downloads the ACPI linker/loader script from QEMU when the edk2 PCI Bus driver globally signals the firmware that PCI enumeration and resource allocation have completed. At this point QEMU regenerates the ACPI payload in an fw_cfg read callback, and this is when the PXB's _CRS gets populated. Unfortunately, when this happens, the PCI_COMMAND_MEMORY bit is clear in the root bus's command register, *unlike* under SeaBIOS. The consequences unfold as follows: - When build_crs() fetches dev->io_regions[i].addr, it is all-bits-one, because pci_update_mappings() --> pci_bar_address() calculated it as PCI_BAR_UNMAPPED, due to the PCI_COMMAND_MEMORY bit being clear. - Consequently, the SHPC MMIO BAR (bar 0) of the bridge is not added to the _CRS, *despite* having been programmed in PCI config space. - Similarly, the SHPC MMIO BAR of the PXB is not removed from the main root bus's DWordMemory descriptor. - Guest OSes (Linux and Windows alike) notice the pre-programmed SHPC BAR within the PXB's config space, and notice that it conflicts with the main root bus's memory resource descriptors. Linux reports pci 0000:04:00.0: BAR 0: can't assign mem (size 0x100) pci 0000:04:00.0: BAR 0: trying firmware assignment [mem 0x88200000-0x882000ff 64bit] pci 0000:04:00.0: BAR 0: [mem 0x88200000-0x882000ff 64bit] conflicts with PCI Bus 0000:00 [mem 0x88200000-0xfebfffff] While Windows Server 2012 R2 reports https://technet.microsoft.com/en-us/library/cc732199%28v=ws.10%29.aspx This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12) This issue was apparently encountered earlier, see the "hack" in: https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02983.html and the current hole-punching logic in build_crs() and build_ssdt() is probably supposed to remedy exactly that problem -- however, for OVMF they don't work, because at the end of the PCI enumeration and resource allocation, which cues the ACPI linker/loader client, the command register is clear. The "shpc" property of "pci-bridge", introduced in the previous patches, allows us to disable the standard hotplug controller cleanly, eliminating the SHPC bar and the conflict. Cc: Michael S.

2015-06-23util/qemu-sockets: improve ai_flag hints for ipv6 hostsWolfgang Bumiller
*) Do not use AI_ADDRCONFIG on listening sockets, because this flag makes it impossible to explicitly listen on '127.0.0.1' if no global ipv4 address is configured additionally, making this a very uncomfortable option. *) Add AI_V4MAPPED hint for connecting sockets. If your system is globally only connected via ipv6 you often still want to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't also have an ipv6 entry). For example, PVE - unless explicitly asking for insecure mode - uses ipv4 loopback addresses with QEMU for live migrations tunneled over SSH. These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to work with '127.0.0.1'. As for the AI_V4MAPPED flag: glibc uses it by default, and providing non-0 flags removes it. I think it makes sense to use it. I also want to point out that glibc explicitly sidesteps POSIX standards when passing 0 as hints by then assuming both AI_V4MAPPED and AI_ADDRCONFIG (the latter being a rather weird choice IMO), while according to POSIX.1-2001 it should be assumed 0. (glibc considers its choice an improvement.) Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's default flags in turn are disabled again unless explicitly added, which I do with this patch.

This file is not used (it is included from include/libdecnumber/dpd/decimal128.h, so version in include/ is used). More, the version in include/ can also be removed, since none of the 3 defines from that file are actually used by the code.

2015-06-23Revert "xen-hvm: increase maxmem before calling xc_domain_populate_physmap"Stefano Stabellini
This reverts commit c1d322e6048796296555dd36fdd102d7fa2f50bf. The original commit fixes a bug when assigning a large number of devices which require option roms to a guest. (One known configuration that needs extra memory is having more than 4 emulated NICs assigned. Three or fewer NICs seems to work without this functionality.) However, by unilaterally increasing maxmem, it introduces two problems. First, now libxl's calculation of the required maxmem during migration is broken -- any guest which exercised this functionality will fail on migration. (Guests which have the default number of devices are not affected.) Secondly, it makes it impossible for a higher-level toolstack or administer to predict how much memory a VM will actually use, making it much more difficult to effectively use all of the memory on a machine.
