Subject: [Patch v7 0/4] Support VMBUS channels without monitoring enabled
Date: Tue, 29 Jul 2025 17:09:39 -0700 [thread overview]
Message-ID: <1753834183-22244-1-git-send-email-longli@linuxonhyperv.com> (raw)
From: Long Li <longli@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-longli@linuxonhyperv.com/
Change log:
v3: Add in the comment on the VMBUS API deprecation notice
v7: Dropped the first two patches in the seires as they have already been applied to net-next
Long Li (4):
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
