2023-06-27console/win32: allocate shareable display surfaceMarc-André Lureau
Introduce qemu_win32_map_alloc() and qemu_win32_map_free() to allocate shared memory mapping. The handle can be used to share the mapping with another process. Teach qemu_create_displaysurface() to allocate shared memory. Following patches will introduce other places for shared memory allocation. Other patches for -display dbus will share the memory when possible with the client, to avoid expensive memory copy between the processes.

2023-06-27ui/dbus: introduce "Interfaces" propertiesMarc-André Lureau
This property is similar to ``org.freedesktop.DBus.Interfaces`` property on the bus interface: it's an array of strings listing the extra interfaces and capabilities available, in a convenient way. Most interfaces are implicit, as they are required. For ``org/qemu/Display1_$id``, we can list the Keyboard And Mouse interfaces. Those could be optional.

2023-06-27ui/dbus: win32 supportMarc-André Lureau
D-Bus doesn't support fd-passing on Windows (AF_UNIX doesn't have SCM_RIGHTS yet, but there are other means to share objects. I have proposed various solutions upstream, but none seem fitting enough atm). To make the "-display dbus" work on Windows, implement an alternative D-Bus interface where all the 'h' (FDs) arguments are replaced with 'ay' (WSASocketW data), and sockets are passed to the other end via WSADuplicateSocket().

2023-06-27scripts: add a XML preprocessor scriptMarc-André Lureau
gdbus-codegen doesn't support conditions or pre-processing. Rather than duplicating D-Bus interfaces for win32 adaptation, let's have a preprocess step, so we can have platform-specific interfaces. The python script is based on https://github.com/peitaosu/XML-Preprocessor, with bug fixes, some testing and replacing lxml dependency with the built-in xml module. This preprocessing syntax style is not very common, but is similar to the one provided by WiX (https://wixtoolset.org/docs/v3/overview/preprocessor/) or wixl, that we adopted in QEMU for packaging the guest agent.

2023-06-27virtio-gpu-udmabuf: create udmabuf for blob even when iov_cnt == 1Dongwon Kim
There were often cases where a scanout blob sometimes has just 1 entry that is linked to many pages in it. So just checking whether iov_cnt is 1 is not enough for screening small, non-scanout blobs. Therefore adding iov_len check as well to make sure it creates an udmabuf only for a scanout blob, which is at least bigger than one page size.

2023-06-27icount: don't adjust virtual time backwards after warpNicholas Piggin
The icount-based QEMU_CLOCK_VIRTUAL runs ahead of the RT clock at times. When warping, it is possible it is still ahead at the end of the warp, which causes icount adaptive mode to adjust it backward. This can result in the machine observing time going backwards. Prevent this by clamping adaptive adjustment to 0 at minimum.

2023-06-26vhost-vdpa: do not cleanup the vdpa/vhost-net structures if peer nic is presentAni Sinha
When a peer nic is still attached to the vdpa backend, it is too early to free up the vhost-net and vdpa structures. If these structures are freed here, then QEMU crashes when the guest is being shut down. The following call chain would result in an assertion failure since the pointer returned from vhost_vdpa_get_vhost_net() would be NULL: do_vm_stop() -> vm_state_notify() -> virtio_set_status() -> virtio_net_vhost_status() -> get_vhost_net(). Therefore, we defer freeing up the structures until at guest shutdown time when qemu_cleanup() calls net_cleanup() which then calls qemu_del_net_client() which would eventually call vhost_vdpa_cleanup() again to free up the structures. This time, the loop in net_cleanup() ensures that vhost_vdpa_cleanup() will be called one last time when all the peer nics are detached and freed. All unit tests pass with this change.

2023-06-26intel_iommu: Fix address space unmapZhenzhong Duan
During address space unmap, corresponding IOVA tree entries are also removed. But DMAMap is set beyond notifier's scope by 1, so in theory there is possibility to remove a continuous entry above the notifier's scope but falling in adjacent notifier's scope. There is no issue currently as no use cases allocate notifiers continuously, but let's be robust.

2023-06-26intel_iommu: Fix flag check in replayZhenzhong Duan
Replay doesn't notify registered notifiers but the one passed to it. So it's meaningless to check the registered notifier's synthetic flag. There is no issue currently as all replay use cases have MAP flag set, but let's be robust.
