From: Long Li <lon...@microsoft.com> Hyperv may expose VMBUS channels without monitoring enabled. In this case, it programs almost all the data traffic to VF.
This patchset enabled vmbus/netvsc to use channels without monitoring enabled. This needs to change the APIs exposed by drivers/bus/vmbus. Because those APIs are used only by NetVSC PMD and not feasible for use by a DPDK application, all VMBUS APIs are set to deprecate in upcoming 25.11 release. The notice for deprecation is accepted in the following patch: https://patchwork.dpdk.org/project/dpdk/patch/1742242184-19600-1-git-send-email-lon...@linuxonhyperv.com/ Change log: v3: Add in the comment on the VMBUS API deprecation notice Long Li (6): net/netvsc: introduce private data for storing vmbus device for secondary process net/netvsc: introduce get_vmbus_device to get the vmbus device bus/vmbus: store UIO fd for secondary process bus/vmbus: support channels without monitoring enabled bus/vmbus: add rte_vmbus_device to all functions accessing vmbus bus/vmbus: set event for channel without monitoring support drivers/bus/vmbus/linux/vmbus_bus.c | 9 +++-- drivers/bus/vmbus/linux/vmbus_uio.c | 6 +-- drivers/bus/vmbus/private.h | 2 +- drivers/bus/vmbus/rte_bus_vmbus.h | 16 +++++--- drivers/bus/vmbus/vmbus_channel.c | 57 ++++++++++++++++++++-------- drivers/bus/vmbus/vmbus_common_uio.c | 9 +++-- drivers/net/netvsc/hn_ethdev.c | 44 ++++++++++++++++----- drivers/net/netvsc/hn_nvs.c | 33 +++++++++++----- drivers/net/netvsc/hn_nvs.h | 21 ++++++---- drivers/net/netvsc/hn_rndis.c | 11 +++--- drivers/net/netvsc/hn_rxtx.c | 16 ++++---- 11 files changed, 155 insertions(+), 69 deletions(-) -- 2.34.1
