      qdev: fix get_fw_dev_path to support to add nothing to fw_dev_path · bbfa18fc
      由 Amos Kong 提交于 
      Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path
could not be identified by seabios. It causes that bootindex parameter
of scsi device doesn't work.

This patch implements get_fw_dev_path() in BusClass, it will be called
if bus doesn't implement the method, tyename will be added to
fw_dev_path. If the implemented method returns NULL, nothing will be
added to fw_dev_path.

It also implements virtio_bus_get_fw_dev_path() to return NULL. Then
QEMU will still pass original style of fw_dev_path to seabios.

v2: only add nothing to fw_dev_path when get_fw_dev_path() is
    implemented and returns NULL. then it will not effect other devices
    don't have get_fw_dev_path() implementation.
v3: implement default get_fw_dev_path() in BusClass

      memory: populate FlatView for new address spaces · f43793c7
      由 Paolo Bonzini 提交于 
      Even a new address space might have a non-empty FlatView.  In order
to initialize it properly, address_space_init should (a) call
memory_region_transaction_commit after the address space is inserted
into the list; (b) force memory_region_transaction_commit to do something.

This bug was latent so far because all address spaces started empty, including
the PCI address space where the bus master region is initially disabled.
However, the target address space of an IOMMU is usually rooted at
get_system_memory(), which might not be empty at the time the IOMMU is created.

      memory: limit sections in the radix tree to the actual address space size · 86a86236
      由 Avi Kivity 提交于 
      The radix tree is statically sized to fit TARGET_PHYS_ADDR_SPACE_BITS.
If a larger memory region is registered, it will overflow.

Fix by limiting any section in the radix tree to the supported size.

This problem was not observed earlier since artificial regions (containers
and aliases) are eliminated by the memory core, leaving only device regions
which have reasonable sizes.  An IOMMU however cannot be eliminated by the
memory core, and may have an artificial size.
