[Qemu-devel] [PATCH 2/2] virtio: Set status early in VirtIODevice parent object |
Date: |
Wed, 27 Jun 2018 13:52:48 +0530 |
To process pending requests for driver status 'VIRTIO_CONFIG_S_DRIVER_OK',
virtio-rng 'set_status' calls 'is_guest_ready' function. This checks if
virtqueue is ready and status is set to 'VIRTIO_CONFIG_S_DRIVER_OK'.
This call is made before new status is updated in VirtIODevice parent object
and calling function uses old status value.
