- Now virtio_address_space_lookup only lookup common/isr/device/notify - MR and exclude their subregions. - - When VHOST_USER_PROTOCOL_F_HOST_NOTIFIER enable, the notify MR has - host-notifier subregions and we need use host-notifier MR to - notify the hardware accelerator directly instead of eventfd notify. - - Further more, maybe common/isr/device MR also has subregions in - the future, so need memory_region_find for each MR incluing - their subregions. - - Add lookup subregion of VirtIOPCIRegion MR instead of only lookup container MR. - - Fixes: a93c8d8 ("virtio-pci: Replace modern_as with direct access to modern_bar") - Co-developed-by: Zuo Boqun <zuoboqun@baidu.com> -
