Subject: [PATCH v6 01/26] virtio_pci: struct virtio_pci_common_cfg add queue_notify_data
Date: Thu, 24 Feb 2022 16:10:37 +0800 [thread overview]
Message-ID: <20220224081102.80224-2-xuanzhuo@linux.alibaba.com> (raw)
In-Reply-To: <20220224081102.80224-1-xuanzhuo@linux.alibaba.com>
Add queue_notify_data in struct virtio_pci_common_cfg, which comes from
here https://github.com/oasis-tcs/virtio-spec/issues/89
For not breaks uABI, add a new struct virtio_pci_common_cfg_notify.
Since I want to add queue_reset after queue_notify_data, I submitted
this patch first.
