2014-03-25target-mips: fix MTHC1 and MFHC1 when FPU in FR=0 modePetar Jovanovic
Previous implementation presumed that FPU registers are 64-bit and are working in 64-bit mode. This change first checks MIPS_HFLAG_F64 and if not set, it does load/store from the odd numbered register pair. Patch by Matthew Fortune.

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.

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.)

2014-03-20spapr: Implement interface to fix device pathnameAlexey Kardashevskiy
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.

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).

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.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi
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.

2014-03-19qom: Don't make link NULL on object_property_set_link() failureStefan Hajnoczi
The error behavior of object_property_set_link() is dangerous. It sets the link property object to NULL if an error occurs. A setter function should either succeed or fail, it shouldn't leave the value NULL on failure.

The path resolution logic in object_property_set_link() should be a separate function. This makes the code easier to read and maintain. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
