2014-08-25pci_bridge: manually destroy memory regions within PCIBridgeWindowsPaolo Bonzini
The regions are destroyed and recreated on configuration space accesses. We need to destroy them before the containing PCIBridgeWindows object is freed.

2013-12-24qdev: Drop misleading qbus_free() functionStefan Hajnoczi
Same reasoning as commit 02a5c4c97422b40034f31265e0f139f7846172a8 ("qdev: Drop misleading qdev_free() function"). The qbus_free() function removes the child from the namespace and decrements the reference count. It does not, however, guarantee to free the child since the refcount may still be held. Just call object_unparent() directly. Suggested-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-12-23pci: do not export pci_bus_resetPaolo Bonzini
qbus_reset_all can be used instead. There is no semantic change because pcibus_reset returns 1 and takes care of the device tree traversal. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-12-10pci: fix address space size for bridgeMichael S. Tsirkin
Address space size for bridge should be full 64 bit, so we should use UINT64_MAX not INT64_MAX as it's size. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-11-05qdev: Drop misleading qdev_free() functionStefan Hajnoczi
The qdev_free() function name is misleading since all the function does is unlink the device from its parent. The device is not necessarily freed. The device will be freed when its QObject refcount reaches zero. It is usual for the parent (bus) to hold the final reference but there are cases where something else holds a reference so "free" is a misleading name. Call object_unparent(obj) directly instead of having a qdev wrapper function.

2013-03-26pci_bridge: Use a default map_irq functionAlex Williamson

2013-03-26pci: Teach PCI Bridges about VGA routingAlex Williamson
Each PCI Bridge has a set of implied VGA regions that are enabled when the VGA bit is set in the bridge control register. This allows VGA devices behind bridges. Unfortunately with VGA Enable, which we formerly allowed but didn't back, comes along some required VGA baggage. VGA Palette Snooping is required, along with VGA 16-bit decoding. We don't yet have support for palette snooping. We also don't have support for 10-bit VGA aliases, the default mode, but we enable the register, even on root ports, to avoid confusing guests. Fortunately there's likely nothing from this century that requires these features, so the missing bits are noted with TODOs.
