Subject: [PATCH v3 06/23] OvmfPkg/VirtioLib: take VirtIo instance in VirtioRingInit/VirtioRingUninit
Date: Wed, 23 Aug 2017 08:22:30 -0400 [thread overview]
Message-ID: <1503490967-5559-7-git-send-email-brijesh.singh@amd.com> (raw)
In-Reply-To: <1503490967-5559-1-git-send-email-brijesh.singh@amd.com>
Passing the VirtIo protocol instance will allow the vring to use
VIRTIO_DEVICE_PROTOCOL.AllocateSharedPages () to allocate vring buffer.
