| * vdpa: Add device migration blockerEugenio Pérez2022-07-201-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the vhost-vdpa device is exposing _F_LOG, adding a migration blocker if it uses CVQ. However, qemu is able to migrate simple devices with no CVQ as long as they use SVQ. To allow it, add a placeholder error to vhost_vdpa, and only add to vhost_dev when used. vhost_dev machinery place the migration blocker if needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | Shadow CVQ will copy buffers on qemu VA, so we avoid TOCTOU attacks from the guest that could set a different state in qemu device model and vdpa device. To do so, it needs to be able to map these new buffers to the device. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Reviewed-by: Michael S.

| * vhost: Add svq avail_handler callbackEugenio Pérez2022-07-203-4/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows external handlers to be aware of new buffers that the guest places in the virtqueue. When this callback is defined the ownership of the guest's virtqueue element is transferred to the callback. This means that if the user wants to forward the descriptor it needs to manually inject it. The callback is also free to process the command by itself and use the element with svq_push.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since this series has already introduced a migration break for the HPPA B160L machine, we can use this opportunity to improve the VMStateDescription for the LASIPS2 device. Add the new int_status field to the VMStateDescription and remodel the ports as separate VMSTATE_STRUCT instances representing each LASIPS2Port. Once this is done, the migration stream can be updated to include buf and loopback_rbne for each port (which is necessary since the values are accessed across separate IO accesses), and drop the port id as this is hardcoded for each port type.

| * | lasips2: switch to using port-based IRQsMark Cave-Ayland2022-07-181-41/+18Star

This enables us to remove the separate PS2 keyboard and PS2 mouse named input gpios from the LASIPS2 device and simplify the register implementation to drive the port IRQ using qemu_set_irq() rather than accessing the LASIPS2 device IRQs directly. As a consequence the IRQ level logic in lasips2_set_irq() can also be simplified accordingly. For now this patch ignores adding the int_status bitmap and simply drops the birq boolean from the vmstate_lasips2 VMStateDescription. This is because the migration stream is already missing some required LASIPS2 fields, and as this series already introduces a migration break for the lasips2 device it is easiest to fix this in a follow-up patch.
