-Subject: igb: Disable threaded IRQ for igb_msix_other
-
-From: Wander Lairson Costa <wander@redhat.com>
-
-[ Upstream commit 338c4d3902feb5be49bfda530a72c7ab860e2c9f ]
-
-During testing of SR-IOV, Red Hat QE encountered an issue where the
-ip link up command intermittently fails for the igbvf interfaces when
-using the PREEMPT_RT variant. Investigation revealed that
-e1000_write_posted_mbx returns an error due to the lack of an ACK
-from e1000_poll_for_ack.
-
-The underlying issue arises from the fact that IRQs are threaded by
-default under PREEMPT_RT. While the exact hardware details are not
-available, it appears that the IRQ handled by igb_msix_other must
-be processed before e1000_poll_for_ack times out. However,
-e1000_write_posted_mbx is called with preemption disabled, leading
-to a scenario where the IRQ is serviced only after the failure of
-e1000_write_posted_mbx.
-
-To resolve this, we set IRQF_NO_THREAD for the affected interrupt,
-ensuring that the kernel handles it immediately, thereby preventing
-the aforementioned error.

-Subject: igb: Disable threaded IRQ for igb_msix_other
-
-From: Wander Lairson Costa <wander@redhat.com>
-
-[ Upstream commit 338c4d3902feb5be49bfda530a72c7ab860e2c9f ]
-
-During testing of SR-IOV, Red Hat QE encountered an issue where the
-ip link up command intermittently fails for the igbvf interfaces when
-using the PREEMPT_RT variant. Investigation revealed that
-e1000_write_posted_mbx returns an error due to the lack of an ACK
-from e1000_poll_for_ack.
-
-The underlying issue arises from the fact that IRQs are threaded by
-default under PREEMPT_RT. While the exact hardware details are not
-available, it appears that the IRQ handled by igb_msix_other must
-be processed before e1000_poll_for_ack times out. However,
-e1000_write_posted_mbx is called with preemption disabled, leading
-to a scenario where the IRQ is serviced only after the failure of
-e1000_write_posted_mbx.
-
-To resolve this, we set IRQF_NO_THREAD for the affected interrupt,
-ensuring that the kernel handles it immediately, thereby preventing
-the aforementioned error.
-
-Reproducer:
-
- #!/bin/bash
-
- # echo 2 > /sys/class/net/ens14f0/device/sriov_numvfs
- ipaddr_vlan=3
- nic_test=ens14f0
- vf=${nic_test}v0
-
- while true; do
- ip link set ${nic_test} mtu 1500
- ip link set ${vf} mtu 1500
- ip link set $vf up
- ip link set ${nic_test} vf 0 vlan ${ipaddr_vlan}
- ip addr add 172.30.${ipaddr_vlan}.1/24 dev ${vf}
- ip addr add 2021:db8:${ipaddr_vlan}::1/64 dev ${vf}
- if ! ip link show $vf | grep 'state UP'; then
- echo 'Error found'
- break
- fi
- ip link set $vf down
- done
