Make use of the new s390 adapter irq routing support to enable real in-kernel irqfds for virtio-ccw with adapter interrupts. Note that s390 doesn't provide the common KVM_CAP_IRQCHIP capability, but rather needs KVM_CAP_S390_IRQCHIP to be enabled. This is to ensure backward compatibility.

Current css code saves the operation request block (orb) in the subchannel structure for later consumption by the start function handler. This might make sense for asynchronous execution of the start function (which qemu doesn't support), but not in our case; it would even be wrong since orb contains a reference to a local variable in the base ssch handler. Let's just pass the orb through the start function call chain for ssch; for rsch, we can pass NULL as the backend function does not use any information passed via the orb there.

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.

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.

The existing load_elf() just returns -1 if it fails to load ELF. However it could be smarter than this and tell more about the failure such as wrong endianness or incompatible platform. This adds additional return codes for wrong architecture, wrong endianness and if the image is not ELF at all. This adds a load_elf_strerror() helper to convert return codes into string messages. This fixes handling of what load_elf() returns for s390x, other callers just check the return value for <0 and this remains unchanged.

Post-order is the only sensible direction for the reset signals. For example, suppose pre-order is used and the parent has some data structures that cache children state (for example a list of active requests). When the reset method is invoked on the parent, these caches could be in any state. If post-order is used, on the other hand, these will be in a known state when the reset method is invoked on the parent. This change means that it is no longer possible to block the visit of the devices, so the callback is changed to return void. This is not a problem, because PCI was returning 1 exactly in order to achieve the same ordering that this patch implements. PCI can then rely on the qdev core having sent a "reset signal" (whatever that means) to the device, and only do the PCI-specific initialization with pci_do_device_reset.
