2014-03-26virtio-net: add vlan receive state to RxFilterInfoAmos Kong
Stefan Fritsch just fixed a virtio-net driver bug [1], virtio-net won't filter out VLAN-tagged packets if VIRTIO_NET_F_CTRL_VLAN isn't negotiated. This patch added a new field to @RxFilterInfo to indicate vlan receive state ('normal', 'none', 'all'). If VIRTIO_NET_F_CTRL_VLAN isn't negotiated, vlan receive state will be 'all', then all VLAN-tagged packets will be received by guest. This patch also fixed a boundary issue in visiting vlan table.

2014-03-26acpi: make SSDT 1.0 spec compliant when possibleMichael S. Tsirkin
The ACPI specification says: The ASL compiler can emit two different AML opcodes for a Package declaration, either PackageOp or VarPackageOp. For small, fixed-length packages, the PackageOp is used and this opcode is compatible with ACPI 1.0. A VarPackageOp will be emitted if any of the following conditions are true: . The NumElements argument is a TermArg that can only be resolved at runtime. . At compile time, NumElements resolves to a constant that is larger than 255. . The PackageList contains more than 255 initializer elements. Note: The ability to create variable-sized packages was first introduced in ACPI 2.0. ACPI 1.0 only allowed fixed-size packages with up to 255 elements. So the spec seems to say a fixed value up to 255 must always be used with PackageOp and not VarPackageOp, and some guests (windows up to win2k8) seem to interpret it like this. Let's do just this, choosing the encoding depending on the number of elements. Fixes 9bcc80cd71892df42605e0c097d85c0237ff45d1 (i386/acpi-build: allow more than 255 elements in CPON). https://bugs.launchpad.net/bugs/1297651 Reported-by: Robert Hu <robert.hu@intel.com> Cc: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Michael S.

2014-03-25osdep: initialize glib threads in all QEMU toolsStefan Hajnoczi
glib versions prior to 2.31.0 require an explicit g_thread_init() call to enable multi-threading. Failure to initialize threading causes glib to take single-threaded code paths without synchronization. For example, the g_slice allocator will crash due to race conditions. Fix this for all QEMU tool programs (qemu-nbd, qemu-io, qemu-img) by moving the g_thread_init() call from vl.c:main() into a new osdep.c:thread_init() constructor function. thread_init() has __attribute__((constructor)) and is automatically invoked by the runtime during startup. We can now drop the "simple" trace backend's g_thread_init() call since thread_init() already called it. Note that we must keep coroutine-gthread.c's g_thread_init() call which is located in a constructor function. There is no guarantee for constructor function ordering so thread_init() may only be called later.

This fixes SCSI disks' device node names (which are wildcard nodes in the device-tree), for spapr-vscsi, virtio-scsi and usb-storage. This fixes PHB name from "pci" to "pci@XXXX" where XXXX is a BUID as there is no bus on top of sPAPRPHBState where PHB firmware name could be fixed using the BusClass::get_fw_dev_path() mechanism.

2014-03-20target-ppc: Introduce powerisa-207-server flagAlexey Kardashevskiy
This flag will be used to decide whether to emulate some bits of H_SET_MODE hypercall because some are POWER8-only. While we are here, add 2.05 flag to POWER8 family too. POWER7/7+ already have it.

2014-03-20target-ppc: Force CPU threads count to be a power of 2Bharata B Rao
PowerPC kernel expects the number of SMT threads in a core to be a power of 2. Since QEMU doesn't enforce this, it leads to an early guest kernel crash if invalid threads count is specified. Prevent this crash and make it a graceful exit from QEMU itself by validating the user-supplied threads count.
