Subject: [PATCH v3 0/3] net/virtio: support IOVA as PA mode for vDPA backend
Date: Wed, 3 Jul 2024 15:33:50 +0530 [thread overview]
Message-ID: <20240703100353.2243038-1-schalla@marvell.com> (raw)
In-Reply-To: <20240229132919.2186118-2-schalla@marvell.com>
This patch series makes Virtio-user works in IOVA as PA mode
for vDPA backend.
First patch fixes the issue when having buffer IOVA address in
control queue descriptors.
Second and third patches helps to share descriptor IOVA address,
to the vhost backend. And also disables the use_va flag for VDPA
backend type.
v1->v2:
- Split single patch into three patches.
v2->v3:
- Addressed the review comment by using rte_mem_iova2virt() for desc
address translation.
Srujana Challa (3):
net/virtio_user: convert cq descriptor IOVA address to Virtual address
net/virtio: store desc IOVA address in vring data structure
net/virtio_user: support sharing vq descriptor IOVA to the backend
