Formerly, ifcvf driver has implemented a lazy-initialization mechanism
for the virtqueues and other config space contents,
it would store all configurations that passed down from the userspace,
then load them to the device config space upon DRIVER_OK.
This can not serve live migration, so this series implement an
immediate initialization mechanism, which means rather than the
former store-load process, the virtio operations like vq ops
would take immediate actions by access the virtio registers.
This series also implement irq synchronization in the reset
routine
Please, prefix each patch subject with vDPA/ifcvf:
I will fix this in V2. Thanks
Zhu Lingshan (5):
virt queue ops take immediate actions
get_driver_features from virito registers
retire ifcvf_start_datapath and ifcvf_add_status
synchronize irqs in the reset routine
a vendor driver should not set _CONFIG_S_FAILED
