2014-03-19qom: Add check() argument to object_property_add_link()Stefan Hajnoczi9-3/+33
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 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.

2014-03-18pl011: fix UARTRSR accesses corrupting the UARTCR valueRob Herring1-7/+10
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.

2014-03-18ahci: fix sysbus supportRob Herring1-5/+8
Non-PCI AHCI support is broken due to assertion failures when trying to convert AHCIState to a PCIDevice pointer as AHCIState can have different container structs. Fix this by using the non-asserting object cast and checking the returned pointer is not NULL. The AddressSpace pointer is also being initialized to NULL and causing dma_memory_map call to fail. Fix this by initializing to address_space_memory for sysbus instances. Also correct AHCI_VMSTATE to use the correct container SysbusAHCIState for sysbus instances.

Since we now have a CPU property for the reset value of the CBAR, we can just fix the vexpress board model to correctly set CBAR so SMP works again.

Before spapr_vga_init will returned false if the vga is specified by the command '-device VGA' because vga_interface_type was evaluated to VGA_NONE. With the change in previous patch of this series, spapr_vga_init should return true if it's told that the vga will be initialized in flow of the generic devices initialization. To keep '-nodefaults' have the semantics of bare minimum, it adds a check of 'has_defaults' in usb_enabled() to avoid that a USB controller is added by '-nodefautls, -device VGA' implicitly. This patch also makes two cleanups: 1. skip initialization for VGA_NONE 2. remove the useless 'break' Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Mark Wu <wudxw@linux.vnet.ibm.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13raven: Move BIOS loading from board code to PCI hostHervé Poussineau2-40/+57
Raven datasheet explains where firmware lives in system memory, so do it there instead of in board code. Other boards using the same PCI host will not have to copy the firmware loading code.

2014-03-13target-i386: Enable x2apic by default on KVMEduardo Habkost2-0/+2
When on KVM mode, enable x2apic by default on all CPU models. Normally we try to keep the CPU model definitions as close as the real CPUs as possible, but x2apic can be emulated by KVM without host CPU support for x2apic, and it improves performance by reducing APIC access overhead. x2apic emulation is available on KVM since 2009 (Linux 2.6.32-rc1), there's no reason for not enabling x2apic by default when running KVM.

2014-03-13dataplane: replace internal thread with IOThreadStefan Hajnoczi1-42/+54
Today virtio-blk dataplane uses a 1:1 device-per-thread model. Now that IOThreads have been introduced we can generalize this to N:M devices per threads. This patch drops thread code from dataplane in favor of running inside an IOThread AioContext. As a bonus we solve the case where a guest keeps submitting I/O requests while dataplane is trying to stop. Previously the dataplane thread would continue to process requests until the request gave it a break. Now we can shut down in bounded time thanks to aio_context_acquire/release.

2014-03-13iothread: add "iothread" qdev property typeStefan Hajnoczi1-0/+51
Add a "iothread" qdev property type so devices can be hooked up to an IOThread from the comand-line: qemu -object iothread,id=iothread0 \ -device some-device,x-iothread=iothread0 Note that Paolo Bonzini <pbonzini@redhat.com> has suggested using QOM links instead. This way the relationship between the objects is reflected in QOM. There are currently shortcomings of object_property_add_link() which prevent this use case. I will attempt to fix them and move to QOM links in a separate series. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
