2009-07-16qemu-io: use BDRV_O_FILE to implement the growable open optionChristoph Hellwig
Instead of doing our own check for protocols which fails because raw isn't formally a protocol but special cased in find_protocol specify the BDRV_O_FILE option to use the same code as bdrv_file_open does. While we're at it also add the missing documentation for -g to the main qemu-io help string. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-16qemu-io: Implement bdrv_load_vmstate/bdrv_save_vmstateKevin Wolf
The load_vmstate and save_vmstate functions are implemented as a variation of the normal read/write operation, enabled by the -b option. This is the same mechanism as is used to switch from read/write to pread/pwrite. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-16ioport: use uint{32, 16, 8}_t for ioport value and pio_addr_t for ioport ↵Isaku Yamahata
address. Using int for cpu_{in, out}[bwl] is inconsistent with other part because for address or value, uintN_t is used by other qemu part. At least, softmmu, CPU{Read, Write}MemoryFunc, pci, target_phys_addr_t and the callers of cpu_{in, out}[bwl](). This patch removes the inconsistency. IO port has its own address space so define pio_addr_t as uint32_t because PCI io space width is 32bit. And use uint{32, 16, 8}_t for ioport value. Changing signedness of value might cause subtle issue. However only a suspicious caller is kvm_handle_io() which is ok. And other callers pass unsigned value in the first place.

2009-07-16raw-posix: Handle errors in raw_createStefan Weil
In qemu-iotests, some large images are created using qemu-img. Without checks for errors, qemu-img will just create an empty image, and later read / write tests will fail.

2009-07-16omit 3DNOW! CPUID bits from qemu64 CPU modelAndre Przywara
Since we recently do not disable 3DNOW! support anymore, we should avoid setting the bits in the default qemu64 CPU model to ease migration. TCG does not support it anyway and even AMD deprecates it's usage nowadays. If you want to use it in KVM, use the phenom, athlon or host CPU model.

2009-07-16honor -S on incoming migrationPaolo Bonzini
-S is not honored by qemu on incoming migration. If a domain is migrated while paused, thus, it will start running on the remote machine; this is wrong. Given the trivial patch to fix this, it looks more like a thinko than anything else, probably dating back to the qemu-kvm merge. The interesting part is that the -S mechanism was in fact *used* when migrating (setting autostart = 0) and the incoming migration code was starting the VM at the end of the migration. Since I was removing the vm_start from there, I also corrected a related imprecision. The code was doing a vm_stop "just in case", but we can be sure that the VM is not running---the vm_start call in vl.c has not been reached yet. So the vm_stop is removed together with the vm_start.

The VM state offset is a concept internal to the image format.

2009-07-16bios: Fix multiple calls into smbios_load_exAnthony Liguori
We're marking the used entry bitmap in smbios_load_external() for each type we check, regardless of whether we loaded anything. This makes subsequent calls behave as if we've already loaded the tables from qemu and can result in missing tables (ex. multiple type4 entries on an SMP guest). Only mark the bitmap if we actually load something. Signed-off-by: Alex Williamson <alex.williamson@hp.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-16Change default PCI class of virtio-console to PCI_CLASS_SERIAL_OTHERMark McLoughlin
We're using PCI_CLASS_DISPLAY_OTHER now, but qemu-kvm.git is using PCI_CLASS_OTHERS because: "As a PCI_CLASS_DISPLAY_OTHER, it reduces primary display somehow on Windows XP (possibly Windows disables acceleration since it fails to find a driver)." While this is valid, many versions of X will get confused by it. Class major number of 0 gets treated as a possibly prehistoric VGA device, and then the autoconfig logic gets confused trying to figure out whether the virtio console or the pv vga device are the real VGA. We should really set a proper class ID. 0x0780 (serial / other) seems most appropriate. This shouldn't require any kernel changes, the modalias for virtio looks like: alias: pci:v00001AF4d*sv*sd*bc*sc*i* so won't care what the base class or subclass are. It shows up in the guest as: 00:05.0 Communication controller: Qumranet, Inc.

2009-07-12gdb-xml: fix hacks in powerpc register numberingNathan Froyd
The powerpc xml files contained a hack--an empty, non-existent register--for getting the register numbers to line up for newer (XML-aware) and older (non-XML-aware) GDB. While this hack worked in some cases, it didn't work in all cases, notably when the user used `finish' or `continue': GDB would attempt to read the non-existent register and QEMU would complain. This patch fixes things up properly. Instead of inserting a fake register, we explicitly declare the floating-point and SPE registers to start at 71. This action accomplishes the same thing as the nasty hack, except that now GDB never tries to fetch the non-existant register 70.

2009-07-12target-ppc: fix evmergelo and evmergelohiNathan Froyd
For 32-bit PPC targets, we translated: evmergelo rX, rX, rY as: rX-lo = rY-lo rX-hi = rX-lo which is wrong, because we should be transferring rX-lo first. This problem is fixed by swapping the order in which we write the parts of rX. Similarly, we translated: evmergelohi rX, rX, rY as: rX-lo = rY-hi rX-hi = rX-lo In this case, we can't swap the assignment statements, because that would just cause problems for: evmergelohi rX, rY, rX Instead, we detect the first case and save rX-lo in a temporary variable: tmp = rX-lo rX-lo = rY-hi rX-hi = tmp These problems don't occur on PPC64 targets because we don't split the SPE registers into hi/lo parts for such targets.
