2013-04-22qcow2: allow sub-cluster compressed write to last clusterStefan Hajnoczi
Compression in qcow2 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. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-04-20qdev: Drop taddr propertiesPeter Maydell
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.

2013-04-19target-arm: Correctly restore FPSCRPeter Maydell
Use the helper functions to save and restore the FPSCR, so that we correctly propagate rounding mode and flushing behaviour into the float_status fields. This also allows us to stop saving the vector length/stride fields separately. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2013-04-19target-arm: Add some missing CPU state fields to VMStatePeter Maydell

2013-04-19target-arm: port ARM CPU save/load to use VMStateJuan Quintela
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. Signed-off-by: Juan Quintela <quintela@redhat.com> [PMM: fixed conflicts, updated to use cpu_class_set_vmsd(), updated with new/removed fields since original patch, changed to use custom VMStateInfo for cpsr rather than presave/postload hooks, corrected subsection names so vmload doesn't fail] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

Since patch 81465888c5306cd94abb9847e560796fd13d3c2f target-arm: factor out handling of SRS instruction the ARM mode SRS instruction has not worked in QEMU. The problem is a missing return directive that was removed in the refactoring, so after decoding the instruction, qemu would fall through to generate an UNDEF exception for an illegal instruction.

2013-04-19hw/versatile_pci: Drop unnecessary vpb_pci_config_addr()Peter Maydell
Drop the vpb_pci_config_addr() function -- it is unnecessary since the size of the memory regions means the hwaddr is always within the 24 bit size. (This function was probably a leftover from when read/write functions were called with absolute addresses rather than relative ones.)

2013-04-19versatile_pci: Expose PCI memory space to systemPeter Maydell
The VersatilePB's PCI controller exposes the PCI memory space to the system via three regions controlled by the mapping control registers.

2013-04-19arm/realview: Fix mapping of PCI regionsPeter Maydell
Fix the mapping of the PCI regions for the realview board, which were all incorrect. (This was never noticed because the Linux kernel doesn't actually include a PCI driver for the realview boards.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Paul Brook <paul@codesourcery.com>
2013-04-19versatile_pci: Implement the PCI controller's control registersPeter Maydell
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.

2013-04-19versatile_pci: Implement the correct PCI IRQ mappingPeter Maydell
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. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2013-04-19versatile_pci: Put the host bridge PCI device at slot 29Peter Maydell
On real hardware the host bridge appears as a PCI device in slot 29, so make QEMU put its host bridge in that slot too. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Paul Brook <paul@codesourcery.com>
2013-04-19versatile_pci: Use separate PCI I/O space rather than system I/O spacePeter Maydell
Rather than overloading the system I/O space (which doesn't even make any sense on ARM) for PCI I/O, create an memory region in the PCI controller and use that to represent the I/O space. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Paul Brook <paul@codesourcery.com>
2013-04-19versatile_pci: Change to subclassing TYPE_PCI_HOST_BRIDGEPeter Maydell

2013-04-19versatile_pci: Update to realize and instance init functionsPeter Maydell
Update the Versatile PCI controller to use a realize function rather than SysBusDevice::init. To reflect the fact that the 'realview_pci' class is taking most of its implementation from 'versatile_pci' (and to make the QOM casts work) we make 'realview_pci' a subclass of 'versatile_pci'.

2013-04-19versatile_pci: Expose PCI I/O region on Versatile PBPeter Maydell
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. This change removes the only currently implemented difference between the realview-pci and versatile-pci models; however there are other differences in not-yet-implemented functionality, so we retain the distinction between the two device types.
