Under the standard of Virtio 1.0, the initialization process of the device must first write sub-features back to device before using device, such as finding vqs. There are four places using vp_find_vq(). 1. virtio-blk.pci: put the code of finalizing features in front of using device 2. virtio-blk.mmio: put the code of finalizing features in front of using device 3. virtio-scsi.pci: is ok 4. virtio-scsi.mmio: add the code of finalizing features before vp_find_vq() Link: https://www.mail-archive.com/qemu-devel@nongnu.org/msg920776.html Signed-off-by: Xuan Zhuo <xuanzhuo@linux.alibaba.com> Acked-by: Michael S.
