* virtio: verify features on loadMichael S. Tsirkin2009-12-121-2/+10
| | | | | | | | | | | | | migrating between hosts which have different features might break silently, if the migration destination does not support some features supported by source. Prevent this from happening by comparing acked feature bits with the mask supported by the device. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> (cherry picked from commit 6d74ca5aa83b83fb52332f7735c61ecb7a5328c1)

* Revert "Get rid of _t suffix"Anthony Liguori2009-10-011-6/+6
| | | | | | | | | | | | In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

* qdev: add return value to init() callbacks.Gerd Hoffmann2009-08-271-3/+4
| | | | | | | | | | | | | | | | | | Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

* Revert "Introduce reset notifier order"Jan Kiszka2009-06-291-1/+1
| | | | | | | | | This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (and updates later added users of qemu_register_reset), we solved the problem it originally addressed less invasively.

* qemu/virtio: virtio support for many interrupt vectorsMichael S. Tsirkin2009-06-241-3/+10
| | | | | | | | | | | | Extend virtio to support many interrupt vectors, and rearrange code in preparation for multi-vector support (mostly move reset out to bindings, because we will have to reset the vectors in transport-specific code). Actual bindings in pci, and use in net, to follow. Load and save are not connected to bindings yet, so they are left stubbed out for now. Signed-off-by: Michael S.

* Remove io_index argument from cpu_register_io_memory()Avi Kivity2009-06-161-1/+1
| | | | | | | | | The parameter is always zero except when registering the three internal io regions (ROM, unassigned, notdirty). Remove the parameter to reduce the API's power, thus facilitating future change. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
