The set_config callback function vhost_vdpa_device_get_config in vdpa-dev does not fetch the current device status from the hardware device, causing the guest os to not receive the latest device status information. The hardware updates the config status of the vdpa device and then notifies the os. The guest os receives an interrupt notification, triggering a get_config access in the kernel, which then enters qemu internally. Ultimately, the vhost_vdpa_device_get_config function of vdpa-dev is called One scenario encountered is when the device needs to bring down the vdpa net device. After modifying the status field of virtio_net_config in the hardware, it sends an interrupt notification. However, the guest os always receives the STATUS field as VIRTIO_NET_S_LINK_UP.

gitdm.config
#
# This is the gitdm configuration file for QEMU.
#
# It is to be used with LWN's git dataminer tool for generating
# reports about development activity in the QEMU repo. The LWN gitdm
# tool can be found at:
#
# git://git.lwn.net/gitdm.git
#
# A run to generate a report for the last year of activity would be
#
# git log --numstat --since "Last Year" | gitdm -n -l 10
