Hi all:
This series intends to introduce Intel IFC VF NIC driver for Vhost
Data Plane Acceleration(VDPA).
Here comes two main parts, one is ifcvf_base layer, which handles
hardware operations. The other is ifcvf_main layer handles VF
initialization, configuration and removal, which depends on
and complys to:
virtio_mdev https://lkml.org/lkml/2019/11/7/650
vhost_mdev https://lkml.org/lkml/2019/11/7/62
This patchset passed netperf tests.
This is RFC V3, plese help review.
Changes from V2:
removed some unnecessary code.
using a struct ifcvf_lm_cfg to address hw->lm_cfg and operations on it.
set CONFIG_S_FAILED when ifcvf_start_hw() fail.
removed VIRTIO_NET_F_CTRL_VQ and VIRTIO_NET_F_STATUS
replace ifcvf_net_config with virtio_net_config.
minor changes
Changes from V1:
using le32_to_cpu() to convert PCI capabilities.
some set /get operations will sync with the hardware, eg get_status
and get_generation.
remove feature bit VHOST_F_LOG_ALL, add VIRTIO_F_ORDERED_PLATFORM
add get/set_config functions.
split mdev type group into mdev_type_group_virtio and mdev_type_group_vhost
add ifcvf_mdev_get_mdev_features()
coding stype changes.
Zhu Lingshan (2):
This commit introduced ifcvf_base layer, which handles hardware
operations and configurations.
This commit introduced IFC operations for vdpa, which complys to
virtio_mdev and vhost_mdev interfaces, handles IFC VF
initialization, configuration and removal.
