Bug ID: 287
Summary: netvsc PMD/dpdk/azure: Driver lockup with multi-queue
configuration
Product: DPDK
Version: 18.11
Hardware: x86
OS: Linux
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: mohsinmazhar_shaikh@trendmicro.com
Target Milestone: ---
I am running an app using dpdk 18.11 netvsc PMD
(https://doc.dpdk.org/guides/nics/netvsc.html) on "Ubuntu 18.04 LTS" VM on
azure running kernel 4.18.0-1018
(https://launchpad.net/ubuntu/+source/linux-azure/4.18.0-1018.18). The app uses
multi-queue with 2 cores doing RX/TX. The lockup only occurs when doing a
connections/second test i.e. exercising the netvsc interface. When the lockup
occurs the netvsc interface and it's corresponding mellanox slave both can't
rx/tx packets.
I have the following changes to get things to work on azure:
1) I have the following patch applied: (bus/vmbus: fix race in subchannel
creation
https://git.dpdk.org/dpdk/commit/drivers/bus/vmbus?id=4970103e89f4f828669acf3b465e984fdc891e1e)
2) I have to use the same RSS key
(https://github.com/torvalds/linux/blob/master/drivers/net/hyperv/rndis_filter.c#L64)
and hash
function(https://github.com/torvalds/linux/blob/master/drivers/net/hyperv/rndis_filter.c#L808)
as the linux kernel hv_netvsc driver uses, otherwise RSS configuration fails
with following error:

(363.333877400) hn_dev_tx_queue_release(): >>
(363.333891600) Invalid TX queue_id=0
3) I have applied the same RSS key and function to mlx4 PMD.
4) The same traffic test works fine on single core configuration (no
multi-queue /RSS).
