Subject: [PATCH] hyper_dmabuf/virtio: bugfix on acrn_ioreq_add_iorange() usage
|
|
|
|
Align usage of acrn_ioreq_add_iorange according to description
|
|
of change: "VBS-K: bugfix on cwp_ioreq_add_iorange() usage":
|
|
|
|
"However, previous VBS-K rng reference driver mistakenly uses "start"
|
|
and "start + len". This leads to the fact that VBS-K not only
|
|
hooked "kick" register, VIRTIO_PCI_QUEUE_NOTIFY, but also "status"
|
|
register, VIRTIO_PCI_STATUS, mistakenly."
