2014-03-26virtio-net: add vlan receive state to RxFilterInfoAmos Kong1-13/+29
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. Tsirkin1-2/+14
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.

When trying to load an ELF file specified via -kernel, we need to pass load_elf() the ELF machine type corresponding to the CPU we're booting with, not the one corresponding to the softmmu binary we happen to be running. (The two are different in the case of loading a 32-bit ARM ELF file into a 32 bit CPU being emulated by qemu-system aarch64.)

This extends the pseries machine type with the interface to fix firmware pathnames for devices which have @bootindex property. 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. This stores the boot list in the /chosen/qemu,boot-list property of the device tree. "\n" are replaced by spaces to support OF1275.

This introduces a firmware-pathname-change interface definition. If some machines needs to redefine the firmware path format, it has to add the TYPE_FW_PATH_PROVIDER interface to an object that is above the device on the QOM tree (typically /machine).

As suffixes do not make sense for sPAPR's device tree and there is no way to filter them out on the BusState::get_fw_dev_path() level, let's add an ability for the external caller to specify whether to apply suffixes or not. We could handle suffixes in SLOF (ignored for now) but this would require serious rework in the node opening code in SLOF, which has no obvious benefit for the currently emulated sPAPR machine.

There are currently three types of object_property_add_link() callers: 1. The link property may be set at any time. 2. The link property of a DeviceState instance may only be set before realize. 3.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi8-17/+39
Some object_property_add_link() callers expect property deletion to unref the link property object. Other callers expect to manage the refcount themselves. The former are currently broken and therefore leak the link property object. This patch adds a flags argument to object_property_add_link() so the caller can specify which refcount behavior they require. The new OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be unreferenced when the property is deleted. This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c, s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c. Rationale for refcount behavior: * hw/core/qdev.c - bus children are explicitly unreferenced, don't interfere - parent_bus is essentially a read-only property that doesn't hold a refcount, don't unref - hotplug_handler is leaked, do unref * hw/dma/xilinx_axidma.c - rx stream "dma" links are set using set_link, therefore they need unref - tx streams are set using set_link, therefore they need unref * hw/net/xilinx_axienet.c - same reasoning as hw/dma/xilinx_axidma.c * hw/pcmcia/pxa2xx.c - pxa2xx bypasses set_link and therefore does not use refcounts * hw/s390x/s390-virtio-bus.c * hw/virtio/virtio-pci.c * hw/virtio/virtio-rng.c * ui/console.c - set_link is used and there is no explicit unref, do unref Cc: Peter Crosthwaite <peter.crosthwaite@petalogix.com> Cc: Alexander Graf <agraf@suse.de> Cc: Anthony Liguori <aliguori@amazon.com> Cc: "Michael S.

Offset 4 is UARTRSR/UARTECR, not the UARTCR. The UARTCR would be corrupted if the UARTRSR is ever written. Fix by implementing a correct model of the UARTRSR/UARTECR register. Reads of this register simply reflect the error bits in data register. Only breaks can be triggered in QEMU. With the pl011_can_receive function, we effectively have flow control between the host and the model. Framing and parity errors simply don't make sense in the model and will never occur.

2014-03-18pl011: reset the fifo when enabled or disabledRob Herring1-0/+5
Intermittent issues have been seen where no serial input occurs. It appears the pl011 gets in a state where the rx interrupt never fires because the rx interrupt only asserts when crossing the fifo trigger level. The fifo state appears to get out of sync when the pl011 is re-configured. This combined with the rx timeout interrupt not being modeled results in no more rx interrupts. Disabling the fifo is the recommended way to clear the tx fifo in the TRM (section 3.3.8). The behavior in this case for the rx fifo is undefined in the TRM, but having fifo contents to be maintained during configuration changes is not likely expected behavior. Reseting the fifo state when the fifo size is changed is the simplest solution.
