Message-Id: <20220927030117.5635-1-lingshan.zhu@intel.com> Date: Tue, 27 Sep 2022 11:01:11 +0800 From: Zhu Lingshan <lingshan.zhu@...el.com> To: jasowang@...hat.com, mst@...hat.com Cc: virtualization@...ts.linux-foundation.org, netdev@...r.kernel.org, kvm@...r.kernel.org, Zhu Lingshan <lingshan.zhu@...el.com> Subject: [PATCH V2 RESEND 0/6] Conditionally read fields in dev cfg space Resend to fix a typo reace --> race in the commit message. This series intends to read the fields in virtio-net device configuration space conditionally on the feature bits, this means: MTU exists if VIRTIO_NET_F_MTU is set MAC exists if VIRTIO_NET_F_NET is set MQ exists if VIRTIO_NET_F_MQ or VIRTIO_NET_F_RSS is set. This series report device features to userspace and invokes vdpa_config_ops.get_config() rather than vdpa_get_config_unlocked() to read the device config spcae, so no races in vdpa_set_features_unlocked() Thanks! Changes from V1: 1)Better comments for VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES, only in the header file(Jason) 2)Split original 3/4 into separate patches(Jason) 3)Check FEATURES_OK for reporting driver features in vdpa_dev_config_fill (Jason) 4) Add iproute2 example for reporting device features Zhu Lingshan (6): vDPA: allow userspace to query features of a vDPA device vDPA: only report driver features if FEATURES_OK is set vDPA: check VIRTIO_NET_F_RSS for max_virtqueue_paris's presence vDPA: check virtio device features to detect MQ vDPA: fix spars cast warning in vdpa_dev_net_mq_config_fill vDPA: conditionally read MTU and MAC in dev cfg space drivers/vdpa/vdpa.c | 71 ++++++++++++++++++++++++++++++--------- include/uapi/linux/vdpa.h | 4 +++ 2 files changed, 59 insertions(+), 16 deletions(-) -- 2.31.1
