ixgbe: link status for PF up/down is not updating using LSI DPDK16.11.1 Sample App

[Shashikant Poonia]

Hi All,


I am running Link Status Interrupt(LSI) DPDK sample application to test
link status by making PF up/down using 'ip link set dev <intface>
up/down'.  I would think, it should trigger 'ixgbe_dev_interrupt_handler()'
when we do interface up/down. But looks like it is not triggered
'ixgbe_dev_interrupt_handler()' to update link status.


setup details:

DPDK 16.11.1   LSI sample application
Host:    rhel 7.2 having Intel X540  10G card
Guest:  KVM  hypervisor attached VFs

Execute LSI binary on Guest using
./link_status_interrupt -c 2 -n 4 -- -q 2 -p 0x3

My main goal to check the link status of VF's on Guest machine, but looks
like its not updated on PF itself. So once this works then i hope it works
for VF as well

Please do let me know, whether i am missing any configuraion/patch ? Any
help would be appreciated

Hi all, Anybody got a chance to look into ?

BTW, am using below two patches for VF reset on DPDK 16.11

http://dpdk.org/ml/archives/dev/2016-June/040287.html  ::lib/librte_ether:
support device reset

http://dpdk.org/ml/archives/dev/2016-June/040290.html
<http://dpdk.org/ml/archives/dev/2016-June/040289.html>  ::ixgbe: implement
device reset on VF


Having few queries based above patches.

1) Are above patches are sufficient to reset VF ? Along with 2 patches, do
we need to have more fix ?

2) May know, Why above patches are not submitted, Were there any side
effect of both patches ?

3) Is the patch applicable to DPDK 2.1 also along with mailbox process
patch ?

4) Is there any plan to submit above fixes in latest dpdk code ?



Awaiting for the reply .. Thanks in advance.
