[Matej Vido]

Hello Thomas,

CESNET would like to submit new virtual poll mode driver for COMBO-80G and
COMBO-100G cards. This PMD requires libsze2 library and kernel modules
(combov3, szedata2_cv3) to be installed.

We have already sent a patch serie in June
(http://dpdk.org/ml/archives/dev/2015-June/019736.html ), but missed
previous merge window. Now, we are working on a new patchset version with
scattered packets support.

Meanwhile, we have improved the firmware and would like to share the
results of our benchmark:https://www.liberouter.org/wp-content/uploads/2015/09/pmd_szedata2_dpdk_measurement-2015-09-11.pdf

Matej

The name of the driver was szedata2, right?
What is the meaning? Why not having liberouter in its name?

Please try to split the patches in order to ease the review.
One feature per patch is a good rule.

SZE is our Straight ZEro copy technology for fast data transfers between
hardware and RAM, 2 is its second version, _cv3 denotes compatibility with
our third generation of FPGA cards. Liberouter is the name of our team,
which does also other, non-hardware stuff.

In the future we want to rewrite this PMD to be independent on sze library
and kernel modules - that could also further improve performance a little.

Re: [dpdk-dev] DPDK 2.2 roadmap

[David Marchand]

Hello all,

My turn.

As far as the 2.2 is concerned, I have some fixes/changes waiting for going
upstream :
- allow default mac removal (to be discussed)
- kvargs api updates / cleanup (no change on abi, I would say)
- vlan filtering api fixes and ixgbevf/igbvf associated fixes (might have
an impact on abi)
- ethdev fixes wrt hotplug framework
- minor fixes in testpmd

After this, depending on the schedule (so will most likely be for 2.3 or
later), I have some ideas on :
- cleanup for hotplug and maybe discussions on pci bind/unbind operations
- provide a little tool to have informations/capabilities on drivers (à la
modinfo)
- continue work on hotplug


By the way, I have some questions to the community :

- I noticed that with hotplug support, testpmd has become *really* hungry
on mbufs and memory.
The problem comes from the "basic" assumption that we must have enough
memory/mbufs for the maximum number of ports that might be available but
are not in the most common tests setup.
One solution might be to rework the way mbufs are reserved :
* either we let testpmd start with limited mbufs count the way it was
working before edab33b1 ("app/testpmd: support port hotplug"), then when
trying to start a port, this operation can fail if not enough mbufs are
available for it
* or we can try to create one mempool per port. The mempools would be
populated at the port init / close (?).
Anyone volunteers to rework this ?
Other ideas ?


- looking at a patch from Chao (
http://dpdk.org/ml/archives/dev/2015-August/022819.html), I think we need
to rework the way the numa nodes are handled in the dpdk.
The problem is that we rely on static arrays for some resources per socket.
I suppose this was designed with the idea that socket "physical" indexes
are contiguous, but this is not true on systems running power8 bare metal
(where numa indexes can be 0, 1, 16, 17 on quad nodes servers).
I suppose we can go with a mapping array (populated at the same time cpus
are discovered), then use this mapping array and preserve all apis, but
this might not be that trivial.
Volunteers ?
Ideas ?


- finally, looking at the eal, there are still some cleanups to do.
More specifically, are there any users of the ivshmem feature in dpdk ?
I can see little value in keeping the ivshmem feature in the eal (well
maybe because I don't use it) as it relies on hacks.
So I can see two options:
* someone still wants it to work, then we need a good rework to get rid of
those hacks under #ifdef in eal and the special configuration files can
disappear
* or if nobody complains, we can schedule its deprecation then removal.


Thanks.

Currently only 24 bits of GRE key will be used for hash/filter calculation, while 32 bits
was wanted by some of users. So either 24 or 32 bits can be selected by the users
from R2.2.

What we're planning is a sample application that shows how hardware and software crypto accelerators can be used to accelerate a typical workload, which happens to be IPsec. We plan to provide an RFC next week which will give further details on what's being proposed. We don't expect maintenance to be a problem, but we can discuss that further when the scope has been clarified.

For each API, it is really interesting to have some unit tests and some
examples to show how it should be used. However adding an IPsec stack looks
to be beyond the need of an API example. It may be big and difficult to
maintain when updating DPDK.

I had been holding off until some issues found during QA testing and DPDK 2.1 was released.
Now that 2.1 is out, and QA tests are looking good will rebase in a couple of weeks.

I think it's a great idea to create an overall roadmap for the project for 2.2 and beyond. To kick this off, below are the features that we're hoping to submit for the 2.2 release. You should be seeing RFCs and v1 patch sets for these over the next few weeks.

Userspace Ethtool Sample App:  Further enhancements to the userspace ethtool implementation that was submitted in 2.1 including: Implement rte_ethtool shim layer based on rte_ethdev API, Provide a sample application that demonstrates/allows testing of the rte_ethtool API, Implement rte_ethtool_get_ringparam/rte_ethtool_set_ringparam, Rework rte_eth_dev_get_reg_info() so we can get/set HW registers in a convenient way.

Vector PMD for fm10k:  A vector PMD, similar to the one that currently exists for the Intel 10Gbps NICs, will be implemented for fm10k.

DCB for i40e &X550:  DCB support will be extended to the i40e and X550 NICs.

IEEE1588 on X550 & fm10k:  IEEE1588 support will be extended to the X550 and fm10k.

IEEE1588 Sample App:  A sample application for an IEEE1588 Client.

Cryptodev Library:  This implements a cryptodev API and PMDs for the Intel Quick Assist Technology DH895xxC hardware accelerator and the AES-NI multi-buffer software implementation. See http://dpdk.org/ml/archives/dev/2015-August/022930.html for further details.

IPsec Sample App:  A sample application will be provided to show how the cryptodev library can be used to implement IPsec. This will be based on the NetBSD IPsec implementation.

Interrupt Mode for i40e, fm10k & e1000:  Interrupt mode support, which was added in the 2.1 release, will be extended to the 140e, fm10k and e1000.

Completion of PCI Hot Plug:  PCI Hot Plug support, which was added in the 2.0 and 2.1 releases, will be extended to the Xenvirt and Vmxnet3 PMDs.

Increase Number of Next Hops for LPM (IPv4 and IPv6):  The current DPDK implementation for LPM for IPv4 and IPv6 limits the number of next hops to 256, as the next hop ID is an 8-bit long field. The size of the field will  be increased to allow an increased number of next hops.

Performance Thread Sample App:  A sample application will be provided showing how different threading models can be used in DPDK. It will be possible to configure the application for, and contrast forwarding performance of, different threading models including lightweight threads. See http://dpdk.org/ml/archives/dev/2015-September/023186.html for further details.

DPDK Keep-Alive:  The purpose is to detect packet processing core failures (e.g. infinite loop) and ensure the failure of the core does not result in a fault that is not detectable by a management entity.

Vhost Offload Feature Support:  This feature will implement virtio TSO offload to help improve performance.

Common Port Statistics:  This feature will extend the exposed NIC statistics, improving the method of presentation to make it obvious what their purpose is. This functionality is based on the rte_eth_xstats_* extended stats API implemented in DPDK 2.1.

NFV Use-cases using Packet Framework (Edge Router):  Enhancements will be made to the IP_Pipeline application and the Packet Framework libraries so that they can be used to support an Edge Router NFV use case.

Refactor EAL for Non-PCI Devices:  This has been discussed extensively on the mailing list. See the RFCs for Refactor eal driver registration code (http://dpdk.org/ml/archives/dev/2015-September/023257.html) and Remove pci driver from vdevs (http://dpdk.org/ml/archives/dev/2015-August/023016.html).

Vhost Multi-Queue Support:  The vhost-user library will be updated to provide multi-queue support in the host similar to the RSS model so that guest driver may allocate multiple rx/tx queues which then may be used to load balance between cores. See http://dpdk.org/ml/archives/dev/2015-August/022758.html for more details.

Virtio Vhost Optimization:  Virtio and vhost performance will be optimized to allow efficient high performance packet movement between guest and host.

Config Granularity of RSS for i40e:  All RSS hash and filter configurations for IPv4/v6, TCP/UDP, GRE, etc will be implemented for i40e. This includes support for QinQ and tunneled packets.

I40e 32-bit GRE Keys:  Both 24 and 32 bit keys for GRE will be supported for i40e.

X550 Enhancements:  Support VF TSO, more Entries in RSS and per VF RSS, network overlay support with flow director for X550.
         
TSO support for fm10K, igb, ixgbe VF:  Enable TCP Segmentation Offload for fm10K, igb and ixgbe VF.

Ixgbe, i40e and fm10k base code updates.

They should be integrated before 23rd October.

In order to ease cooperation and integration, it would be nice to see
announces or technical details of planned features for 2.2 or 2.3.
Then the roadmap page will be filled accordingly:

Generally speaking, it helps to know what you are working on and what is the
status.

Thanks
