This allows using the file.filename option instead of the string that comes from -drive file=... and is passed around as a separate parameter. The goal is to get rid of this parameter and use the options QDict more consistently. With this option you can access not only the top-level image, but specify a filename for the backing file (currently only if no backing file exists, but we'll allow overriding it later) Signed-off-by: NKevin Wolf <kwolf@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com>

Options starting in "backing." are passed to the backing file now. If you don't need to specify the filename for the backing file, you can add it on the command line instead of in the image file: $ qemu-nbd -t /tmp/test.img $ qemu-img create -f qcow2 empty.qcow2 1G $ qemu-system-x86_64 -drive file=empty.qcow2,backing.file.driver=nbd,\ backing.file.host=localhost Note that this doesn't override the backing filename from the image. If the image has one, this will fail because NBD doesn't want the options and a filename at the same time. Signed-off-by: NKevin Wolf <kwolf@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com>

bdrv_write_compressed() does not allow requests that span the end of the device. Therefore it is useless to zero-pad the last cluster and thereby exceed the end of the device.

Compression in qcow requires image length to be a multiple of the cluster size. Lift this requirement by zero-padding the final cluster when necessary. The virtual disk size is still not cluster-aligned, so the guest cannot access the zero sectors. Note that this is almost identical to the qcow2 version of this code. qcow2's compression code is drawn from qcow.

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.

Port the ARM CPU save/load code to use VMState. Some state is saved in a slightly different order to simplify things -- for example arrays are saved one after the other rather than 'striped', and we always save all 32 VFP registers even if the CPU happens to only have 16. Use one subsection for each feature. This means that we don't need to bump the version field each time that a new feature gets introduced.

The versatile_pci PCI controller has a set of control registers which handle the mapping between PCI and system address spaces. Implement these registers (though for now they have no effect since we don't implement mapping PCI space into system memory at all). The most natural order for our sysbus regions has the control registers at the start, so move all the others down one.

Implement the correct IRQ mapping for the Versatile PCI controller; it differs between realview and versatile boards, but the previous QEMU implementation was correct only for the first PCI card on a versatile board, since we weren't swizzling IRQs based on the slot number. Since this change would otherwise break any uses of PCI on Linux kernels which have an equivalent bug (since they have effectively only been tested against QEMU, not real hardware), we implement a mechanism for automatically detecting those broken kernels and switching back to the old mapping. This works by looking at the values the kernel writes to the PCI_INTERRUPT_LINE register in the config space, which is effectively the interrupt number the kernel expects the device to be using.

Comments in the QEMU source code claim that the version of the PCI controller on the VersatilePB board doesn't support the PCI I/O region, but this is incorrect; expose that region, map it in the correct location, and drop the misleading comments.
