Subject: [PATCH v5 0/8] vDPA driver for Alibaba ENI
Date: Fri, 15 Oct 2021 15:14:53 +0800 [thread overview]
Message-ID: <cover.1634281805.git.wuzongyong@linux.alibaba.com> (raw)
In-Reply-To: <cover.1632882380.git.wuzongyong@linux.alibaba.com>
This series implements the vDPA driver for Alibaba ENI(Elastic Network
Interface) which is build based on virtio-pci 0.9.5 specification.
Changes since V4:
- check return values of get_vq_num_{max,min} when probing devices
- disable the driver on BE host via Kconfig
- add missing commit message
Changes since V3:
- validate VIRTIO_NET_F_MRG_RXBUF when negotiate features
- present F_ORDER_PLATFORM in get_features
- remove endian check since ENI always use litter endian
Changes since V2:
- add new attribute VDPA_ATTR_DEV_MIN_VQ_SIZE instead
VDPA_ATTR_DEV_F_VERSION_1 to guide users to choose correct virtqueue
size as suggested by Jason Wang
- present ACCESS_PLATFORM in get_features callback as suggested by Jason
Wang
- disable this driver on Big Endian host as suggested by Jason Wang
- fix a typo
Changes since V1:
- add new vdpa attribute VDPA_ATTR_DEV_F_VERSION_1 to indicate whether
the vdpa device is legacy
- implement dedicated driver for Alibaba ENI instead a legacy virtio-pci
driver as suggested by Jason Wang
- some bugs fixed
Wu Zongyong (8):
virtio-pci: introduce legacy device module
vdpa: fix typo
vp_vdpa: add vq irq offloading support
vdpa: add new callback get_vq_num_min in vdpa_config_ops
vdpa: min vq num of vdpa device cannot be greater than max vq num
virtio_vdpa: setup correct vq size with callbacks get_vq_num_{max,min}
vdpa: add new attribute VDPA_ATTR_DEV_MIN_VQ_SIZE
eni_vdpa: add vDPA driver for Alibaba ENI
