Subject: [PATCH V4 0/6] ifcvf/vDPA: support query device config space through netlink
Date: Fri, 22 Jul 2022 19:53:03 +0800 [thread overview]
Message-ID: <20220722115309.82746-1-lingshan.zhu@intel.com> (raw)
This series allows userspace to query device config space of vDPA
devices and the management devices through netlink,
to get multi-queue, feature bits and etc.
This series has introduced a new netlink attr
VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES, this should be used to query
features of vDPA devices than the management device.
Please help review.
Thanks!
Zhu Lingshan
Changes from V3:
(1)drop the fixes tags(Parva)
(2)better commit log for patch 1/6(Michael)
(3)assign num_queues to max_supported_vqs than max_vq_pairs(Jason)
(4)initialize virtio pci capabilities in the probe() function.
Changes from V2:
Add fixes tags(Parva)
Changes from V1:
(1) Use __virito16_to_cpu(true, xxx) for the le16 casting(Jason)
(2) Add a comment in ifcvf_get_config_size(), to explain
why we should return the minimum value of
sizeof(struct virtio_net_config) and the onboard
cap size(Jason)
(3) Introduced a new attr VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES
(4) Show the changes of iproute2 output before and after 5/6 patch(Jason)
(5) Fix cast warning in vdpa_fill_stats_rec()
Zhu Lingshan (6):
vDPA/ifcvf: get_config_size should return a value no greater than dev
implementation
vDPA/ifcvf: support userspace to query features and MQ of a management
device
vDPA: allow userspace to query features of a vDPA device
vDPA: !FEATURES_OK should not block querying device config space
vDPA: answer num of queue pairs = 1 to userspace when VIRTIO_NET_F_MQ
== 0
vDPA: fix 'cast to restricted le16' warnings in vdpa.c
