This patch tags all vga cards as not hotpluggable. The qemu standard vga will never ever be hotpluggable. For cirrus + vmware it might be possible to get that work some day. Todays we can't handle that for a number of reasons though. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

rtl8139 includes a cpu_register_io_memory acquired value in it's migration data. This is not only unecessary, but we should treat these values as unique to the VM instances since the value depends on call order. In most cases, this miraculously still works. However, if devices are added or removed from the system, it may represent an ordering change, which could cause the target rtl8139 device to make use of another device's cpu_register_io_memory value. If we detect that a hot-add/remove has occured, include a subsection to restrict migrations only to driver versions known to include this fix.

Create a trivial interface to track whether the machine has been modified since boot. Adding or removing devices will trigger this to return true. An example usage scenario for such an interface is the rtl8139 driver which includes a cpu_register_io_memory() value in it's migration stream. For the majority of migrations, where no hotplug has occured in the machine, this works correctly. Once the machine is modified, we can use this interface to detect that and include a subsection for the device to prevent migrations to rtl8139 versions with this bug.

The device path used for migration is currently broken for for all devices behind a nested bridge. Replace this by a hierarchical list of slot/function numbers, walking the path from root down to device. Add :00 after the domain number so that if there are no nested bridges, this is compatible with what we have now. Note: as pointed out by Gleb, using openfirmware paths might be cleaner, doing this would break compatibility though, and the IDs used are not guest or user visible at all, so breaking the compatibility is probably not worth it.

The issue is, it is assumed that all qbuses, qdeves are under main_system_bus. But there are qbuses whose parent is NULL. So it is necessary to trigger reset for those qbuses. (On the other hand, if NULL is passed to qdev_create(), its parent bus is main_system_bus.) Ideally those buses should be moved under bus controller device which is qdev. But it's not done yet. So register qbus reset handler for qbus whose parent is NULL. Reported-by: NStefan Weil <weil@mail.berlios.de> Signed-off-by: N"Michael S.

Every system should have some sort of main system bus, so sysbus_get_default should always return a valid bus.

Using bus numbers in migration is clearly wrong as they are guest assigned. Not really sure what the right thing to do is, for now stick 0 in there so things keep working for non-nested setups, add a TODO. We also probably have to mark nested bridges as non-migrateable until this is fixed? Signed-off-by: NMichael S. Tsirkin <mst@redhat.com> Acked-by: NAlex Williamson <alex.williamson@redhat.com>

QEMU source code with CRLF line endings which is quite common on windows hosts fails with current make_device_config.sh. The awk script gets the name of the included file with \r, so instead of pci.mak it will search for pci.mak\r which of course does not work. Fix this by removing any \r. v2: Avoid using sub() and \r with awk because they are unsupported on some platforms. Use tr to remove \r. This new solution improves portability and was suggested by Paolo Bonzini.

This patch adds support for the qemu-img check command. It also introduces a dirty bit in the qed header to mark modified images as needing a check. This bit is cleared when the image file is closed cleanly. If an image file is opened and it has the dirty bit set, a consistency check will run and try to fix corrupted table offsets. These corruptions may occur if there is power loss while an allocating write is performed. Once the image is fixed it opens as normal again.

This patch implements the read/write state machine. Operations are fully asynchronous and multiple operations may be active at any time.

This patch adds code to look up data cluster offsets in the image via the L1/L2 tables. The L2 tables are writethrough cached in memory for performance (each read/write requires a lookup so it is essential to cache the tables). With cluster lookup code in place it is possible to implement bdrv_is_allocated() to query the number of contiguous allocated/unallocated clusters.
