When configured with --enable-debug, we compile without optimization. This means that the function mpc8544_copy_soc_cell() in ppce500_mpc8544ds.c is not optimized out, even though it is never called without kvm. That in turn causes a link failure, because it calls the function kvmppc_read_host_property() which is in kvm_ppc.o and therefore not included in a --disable-kvm build. This patch fixes the problem by providing a dummy stub for kvmppc_read_host_property() in kvm_ppc.h when !CONFIG_KVM.

The recent patches adding partial support for POWER7 cpu emulation included implementing the popcntd instruction. The support for this was open coded, but host-utils.h already included a function implementing an equivalent population count function, which uses a gcc builtin (which can use special host instructions) if available. This patch makes the popcntd implementation use the existing, potentially faster, implementation.

At present, the 'pseries' machine creates a flattened device tree in the machine->init function to pass to either the guest kernel or to firmware. However, the machine->init function runs before processing of -device command line options, which means that the device tree so created will be (incorrectly) missing devices specified that way. Supplying a correct device tree is, in any case, part of the required platform entry conditions. Therefore, this patch moves the creation and loading of the device tree from machine->init to a reset callback. The setup of entry point address and initial register state moves with it, which leads to a slight cleanup. This is not, alas, quite enough to make a fully working reset for pseries. For that we would need to reload the firmware images, which on this machine are loaded into RAM. It's a step in the right direction, though.

Currently the pseries machine init code builds up an array, envs, of CPUState pointers for all the cpus in the system. This is kind of pointless, given the generic code already has a perfectly good linked list of the cpus. In addition, there are a number of places which assume that the cpu's cpu_index field is equal to its index in this array. This is true in practice, because cpu_index values are just assigned sequentially, but it's conceptually incorrect and may not always be true. Therefore, this patch abolishes the envs array, and explicitly uses the generic cpu linked list and cpu_index values throughout.

But given that the protocol specifies a byte unit length field we currently accept such requests, which cause qemu to abort() in lower layers.

The specification for the virtio balloon device requres that the values in the config space be encoded little-endian. This differs from most virtio things, where guest-native endian is the norm. Currently, the qemu virtio-balloon code correctly makes the conversion on get_config(), but doesn't on set_config for the 'actual' field. The kernel driver, on the other hand, correctly converts when setting the actual field, but does not convert when reading the config space. The upshot is that virtio-balloon will only work correctly if both host and guest are LE, making all the conversions nops. This patch corrects the qemu side, correctly doing host-native <-> LE conversions when accessing the config space. This won't break any setups that aren't already broken, and fixes the case of BE host, LE guest. Fixing the BE guest case will require kernel fixes as well.

The 9p code already contains an attempt at the necessary endian conversions, but it's broken. The code which does conversion from host to guest does it correctly and this code was copied to the function which does guest to host conversion. However the copied code hasn't been correctly updated, so it first endian converts some garbage on the stack and then overwrites it with a field from incoming packet without conversion. The patch fixes the mistakes.

We need to keep DIR register unchanged across migration, but currently it depends on the media_changed flags from block layer. Since we do not save/restore it and the bdrv_open() called in dest node may set the media_changed flag when trying to open floppy image, guest driver may think the floppy have changed after migration. To fix this, a new filed media_changed in FDrive strcutre was introduced in order to save and restore the it from block layer through pre_save/post_load callbacks.

This commit has the side-effect of making the qemu-nbd binary capable of binding to IPv6 addresses. ("-b ::1", for instance). block/nbd.c fails to parse IPv6 IP addresses correctly at this point, but will work over IPv6 when given a hostname. It still works over IPv4 as before. We move the qemu-sockets object from the 'common' to the 'block' list in the Makefile. The common list includes the block list, so this is effectively a no-op for the rest of the code. We also add 32-bit 'magic' attributes to nbd_(request|reply) to facilitate calculating maximum request/response sizes later.

This fixes the problem when qemu continues even if -drive specification is somehow invalid, resulting in a mess. Applicable for both current master and for stable-0.14 (and the same issue exist 0.13 and 0.12 too). The prob can actually be seriuos: when you start guest with two drives and make an error in the specification of one of them, and the guest has something like a raid array on the two drives, guest may start failing that array or kick "missing" drives which may result in a mess - this is what actually happened to me, I did't want a resync at all, and a resync resulted in re-writing (and allocating) a 4TB virtual drive I used for testing, which in turn resulted in my filesystem filling up and whole thing failing badly. Yes it was just testing VM, I experimented with larger raid arrays, but the end result was quite, well, unexpected.

The block layer caches the device size to avoid doing lseek(fd, 0, SEEK_END) every time this value is needed. For removable media the device size becomes stale if a new medium is inserted. This patch simply prevents device size caching for removable media. A smarter solution is to update the cached device size when a new medium is inserted. Given that there are currently bugs with CD-ROM media change I do not want to implement that approach until we've gotten things correct first.

When removing a drive from the host-side via drive_del we currently have the following path: drive_del qemu_aio_flush() bdrv_close() // zaps bs->drv, which makes any subsequent I/O get // dropped. Works as designed drive_uninit() bdrv_delete() // frees the bs. Since the device is still connected to // bs, any subsequent I/O is a use-after-free. The value of bs->drv becomes unpredictable on free. As long as it remains null, I/O still gets dropped, however it could become non-null at any point after the free resulting SEGVs or other QEMU state corruption. To resolve this issue as simply as possible, we can chose to not actually delete the BlockDriverState pointer. Since bdrv_close() handles setting the drv pointer to NULL, we just need to remove the BlockDriverState from the QLIST that is used to enumerate the block devices. This is currently handled within bdrv_delete, so move this into its own function, bdrv_make_anon(). The result is that we can now invoke drive_del, this closes the file descriptors and sets BlockDriverState->drv to NULL which prevents futher IO to the device, and since we do not free BlockDriverState, we don't have to worry about the copy retained in the block devices. We also don't attempt to remove the qdev property since we are no longer deleting the BlockDriverState on drives with associated drives. This also allows for removing Drives with no devices associated either.
