* PortioList: Store PortioList in device stateKirill Batuzov2014-05-051-3/+4
| | | | | | | | | | | | | | | | | | | | PortioList is an abstraction used for construction of MemoryRegionPortioList from MemoryRegionPortio. It can be used later to unmap created memory regions. It also requires proper cleanup because some of the memory inside is allocated dynamically. By moving PortioList ot device state we make it possible to cleanup later and avoid leaking memory. This change spans several target platforms. The following testcases cover all changed lines: qemu-system-ppc -M prep qemu-system-i386 -vga qxl qemu-system-i386 -M isapc -soundhw adlib -device ib700,id=watchdog0,bus=isa.0 Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

* qom: Add check() argument to object_property_add_link()Stefan Hajnoczi2014-03-191-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* qom: Make QOM link property unref optionalStefan Hajnoczi2014-03-191-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Set cannot_instantiate_with_device_add_yet for the other devices with pointer properties, with a comment explaining why. Juha Riihimäki and Peter Maydell deserve my thanks for making "pointer property must not remain null" blatantly obvious in the OMAP devices. Only device "smbus-eeprom" is actually changed. The others are all sysbus devices, which get cannot_instantiate_with_device_add_yet set in their abstract base's class init function. Setting it again in their class init function is technically redundant, but serves as insurance for when sysbus devices become available with device_add, and as documentation.

* | qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster2013-12-231-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

* qdev: Drop taddr propertiesPeter Maydell2013-04-201-1/+0Star
| | | | | | | | | | | | Drop all the infrastructure for taddr properties (ie ones which are 'hwaddr' sized). These are now unused, and any further desired use would be rather questionable since device properties shouldn't generally depend on a type that is conceptually variable based on the target CPU. 32 or 64 bit integer properties should be used instead as appropriate for the specific device.

* stream: Remove app argument hackPeter Crosthwaite2013-04-161-29/+70
| | | | | | | | | The uint32_t *app argument doesn't exist in real hardware. It was a hack in xilinx_axidma/enet to fake the (secondary) control stream connection. Removed the argument and added the second stream to axienet/dma. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
* xilinx_axienet/dma: Implement rx path flow controlPeter Crosthwaite2013-04-161-8/+41
| | | | | | | | | | | | | | | Implement flow control for the RX data path from xilinx_axienet->xilinx_axidma. On short return from axidma, then ethernet sets up the notify callback to resume transfer from where it left off. This also allows the ethernet to track whether there is an in progress transaction and return false from ethernet can_receive() as appropriate. If the DMA backs up or is disabled it waits for enablement. When the rx stream IO region is touched, the can_push() notify function is called if set.
