Hi
We are developing DPDK based app in VMWARE EXSI 6.0. We have 1 G card
configured as VMXNET3 device. With 16.07 dpdk unmodified the system reboots
when binding the igb_uio driver to the PCI device.
I followed the following guide.

Hi All,
I am seeing an issue where the stats counters for vmxnet3 interfaces are reset
to 0 after rte_eth_dev_start() is called, making it difficult to track
statistics over a period of time where interfaces could be disabled and
re-enabled.
There is a memset in the code that clears the txq/rx
Thanks a lot guys for your support.
I have tried the patch by Yong Wang, stop and start functions are
working fine with out any crash.
I have noticed that tx/rx stats are being reset to 0. I am not sure if
this is valid behavior as we do not reset stats to 0 when we do
ifconfig down and ifconfig up
Waterman/Navakanth, we've got some patches posted for the same by Yong Wang at
VMware. I haven't got the chance to look at it but if you can validate it, it'd
be great.
Thanks,
Rashmin

Hi Rashmin
I have tried the memset change but still I am facing the problem which
I pointed out earlier. After restart, packets are not being received
in vmxnet3_recv_pkts().
I have also observed PANIC in vmxnet3_tq_tx_complete() after couple of
stop and start operations.
PANIC in vmxnet3_tq_tx_c
Hi Rashmin,
We found similar issue when we start/stop vmnet dev several time. (> 3 times)
It happens kernel panic, and sometimes kernel will occur core dump.
Let me know if you want to submit patch to fix it.
Thanks

I just quickly looked into the code and instead of releasing memory or simply
set it to NULL (patch:
http://thread.gmane.org/gmane.comp.networking.dpdk.devel/4683), you can zero
it out and it should work perfectly, you can give it a quick try.

I had tried with Stephen's patch but after stop is done and when we
call start it crashed at vmxnet3_dev_start()->
vmxnet3_dev_rxtx_init()->vmxnet3_post_rx_bufs() as buf_info is freed
and is not allocated again. buf_info is allocated in

Yes I had a local copy working with couple of lines fix. But someone else, I
think Stephen added a fix patch for the same, and I assume if it's been merged,
should be working, so did not follow up later.
I don't have a VMware setup handy at moment but I think Waterman would have
more informati
Hi Rashmin
I have come across your reply in following post that you have worked
on this problem and would submit the patch for it.
Can you please share information on the changes you worked on or patch
log if you had submitted any for it?

Hi
I am using DPDKv1.7.0 running on Vmware Esxi 5.1 and am trying to
reset the port which uses pmd_vmnet3 library functions from below
function calls.

Doing this, i face panic while rte_free(ring->buf_info) in
Vmxnet3_cmd_ring_release().
I have gone through foll
ll submit it after some testing.
Thanks,

Hi,
I'm having a problem with vmxnet-pmd. When I bind vmxnet3 vNIC to
vmxnet3-pmd, I cannot receive ANY packets from vmxnet-pmd.
I'm running dpdk-1.6.0r2 inside ESXi 5.5 VM. The VM has kernel
3.11.0-12-generic.
One thing I notice is that ESXi host does not pass "pdpe1gb" CPU flag to
guest VMs
I dug deeper into the problem vmxnet-pmd not capturing packets. Whenever pmd
stops capturing, it does not respect the number of rxd. For example, I set rxd
to 512. The pkt mbuf mempool I allocate is 4482, which is much bigger than rxd.
I would expect ~512 mbufs to be removed from mempool at any
16 matches
