2014-04-03bswap: Fix build on FreeBSD 10.0Andreas Färber1-0/+2
FreeBSD 10.0-RELEASE has bswap16() etc. macros defined in sys/endian.h, which leads to a conflict with our static inline definitions. Force using the system version of the macros.

2014-03-31cpu: Avoid QOM casts for CPU()Andreas Färber1-1/+6
CPU address spaces touching load and store helpers as well as the movement of (almost) all fields from CPU_COMMON to CPUState have led to a noticeable increase of CPU() usage in "hot" paths for both TCG and KVM. While CPU()'s OBJECT_CHECK() might help detect development errors, i.e. in form of crashes due to QOM vs. non-QOM mismatches rather than QOM type mismatches, it is not really needed at runtime since mostly used in CPU-specific paths, coming from a target-specific CPU subtype. If that pointer is damaged, other errors are highly likely to occur elsewhere anyway. Keep the CPU() macro for a consistent developer experience and for flexibility to exchange its implementation, but turn it into a pure, unchecked C cast for now. Compare commit 6e42be7cd10260fd3a006d94f6c870692bf7a2c0.

2014-03-20qdev: Introduce FWPathProvider interfacePaolo Bonzini1-0/+47
QEMU supports firmware names for all devices in the QEMU tree but some architectures expect some parts of firmware path names in different format. 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).

2014-03-20vl.c: Extend get_boot_devices_list() to ignore suffixesAlexey Kardashevskiy1-1/+1
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.

This changes resource code definitions to ones used in the host kernel. This fixes H_SET_MODE_RESOURCE_LE (switch between big endian and little endian) to sync registers from KVM before changing LPCR value. This adds a set_spr() helper to update an SPR in a CPU's context to avoid possible races and makes use of it to change LPCR.

2014-03-19qom: Add check() argument to object_property_add_link()Stefan Hajnoczi2-0/+29
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. The link property may never be set, it is read-only. Something similar can already be achieved with object_property_add_str()'s set() argument. Follow its example and add a check() argument to object_property_add_link(). Also provide default check() functions for case #1 and #2. Case #3 is covered by passing a NULL function pointer.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi1-1/+10
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.

In the original code, vga_interface_type is evaluated to VGA_NONE even if a VGA is added via '-device VGA'. It causes the machine not aware of the graphics device configured.
