[dpdk-dev] [PATCH v2 2/2] mempool:pktmbuf pool default fallback for mempool ops error

[Hemant Agrawal]

In the rte_pktmbuf_pool_create, if the default external mempool is
not available, the implementation can default to "ring_mp_mc", which
is an software implementation.

[dpdk-dev] [PATCH v2 1/2] eal/mempool: introduce check for external mempool availability

[Hemant Agrawal]

External offloaded mempool may not be available always. This check enables
run time verification of the presence of external mempool before the
mempool ops are installed.

An application built with a specific external mempool may work fine
on host. But, may not work on VM, specificaly if non-hw specific interfaces
are used e.g. virtio-net.

This is required to make sure that same application can work in all
environment for a given hw platform.

The solution proposed here is that rte_mempool_set_ops_byname should return
specific error in case the current execution environment is not supporting
the given mempool. Thereby allowing it to fallback on software mempool
implementation e.g. "ring_mp_mc"

This patch introduces new optional "pool_verify" as mempool ops function
to check if external mempool instance is available or not.

[dpdk-dev] [PATCH 00/19] KNI checkpatch cleanup

[Ferruh Yigit]

KNI checkpatch cleanup, mostly non-functional but cosmetic modifications.
Only functional change is related logging, switched to kernel dynamic
logging and compile time KNI debug options removed, some log message
levels updated.

Ferruh Yigit (19):
  kni: move externs to the header file
  kni: uninitialize global variables
  kni: make static struct const
  kni: whitespace, indentation, long line corrections
  kni: prefer unsigned int to unsigned
  kni: remove useless return
  kni: comparisons should place the constant on the right
  kni: trailing statements should be on next line
  kni: do not use assignment in if condition
  kni: macros with complex values should be enclosed in parentheses
  kni: prefer min_t to min
  kni: prefer ether_addr_copy to memcpy
  kni: update kernel logging
  kni: remove unnecessary 'out of memory' message
  kni: move functions to eliminate function declarations
  kni: remove compile time debug configuration
  kni: updated log messages
  kni: prefer uint32_t to unsigned int
  kni: move kernel version ifdefs to compat header

Applied, thanks

[dpdk-dev] [PATCH] drivers: advertise kmod dependencies in pmdinfo

[Olivier Matz]

Add a new macro DRIVER_REGISTER_KMOD_DEP() that allows a driver to
declare the list of kernel modules required to run properly.

Today, most PCI drivers require uio/vfio.

Signed-off-by: Olivier Matz 
---

rfc -> v1:
- the kmod information can be per-device using a modalias-like
  pattern
- change syntax to use '&' and '|' instead of ',' and ':'
- remove useless prerequisites in kmod lis: no need to
  specify both uio and uio_pci_generic, only the latter is
  required
- update kmod list in szedata2 driver
- remove kmod list in qat driver: it requires more than just loading
  a kmod, which is described in documentation

It would deserve a dedicated thread to discuss legal sense of these things.
I'm not a lawyer but I think "All rights reserved." has no real sense.

RTE_ASSERT is preferred.
We must stop adding some rte_panic calls except for debug.

Yes i were basing it on master, i will base the next version on 
dpdk-next-virtio. Sorry for this, i am bit new to dpdk upstream 
development .

Yes if we don't give the '--switch' option then default is vmdq.

I will fix it, define a different constant for switch_dev name.

I used the string because the registration function (vs_register_switch) 
uses the switch name as string to register the switches and find the 
matching switch_dev given in command line. If we use macro or enum then 
we will have to add the MACRO for the switch id in common code every 
time a new switch implementation is added. Keeping a string as name, 
saves us from touching the common code for adding a new switch 
implementation.

Do you want me to split the vswitch_ops, vswitch_dev and vswitch_port 
introduction (mainly vswitch_common.h) in three patches with the patch 
body explaining them in bit detail, correct ?

Their usage i.e vswitch_common.c can be kept in separate patch (4th 
one), is this fine? otherwise it fill be tricky to make vswitch_common.c 
to compilable without complete definition of vswitch_port, vswitch_dev 
and vswitch_ops

[dpdk-dev] [RFC][PATCH V2 1/3] examples/vhost: Add vswitch (generic switch) framework

Hi Jianfeng,

 Introduce support for a generic framework for handling of switching
 between
 physical and vhost devices. The vswitch framework introduces the
 following
 concept:

 1. vswitch_dev: Vswitch device is a logical switch which can have
 physical and
 virtio devices. The devices are operated/used using standard rte_eth
 API for
 physical devices and lib_vhost API for vhost devices, PMD API is not
 used
 for vhost devices.

 2. vswitch_port: Any physical or virtio device that is added to
 vswitch. The
 port can have its own tx/rx functions for doing data transfer, which
 are exposed
 to the framework using generic function pointers
 (vs_port->do_tx/do_rx). This way
 the generic code can do tx/rx without understanding the type of device
 (Physical or
 virtio). Similarly each port has its own functions to select tx/rx
 queues. The framework
 provides default tx/rx queue selection functions to the port when port
 is added
 (for both physical and vhost devices). But the framework allows the
 switch implementation
 to override the queue selection functions (vs_port->get_txq/rxq) if
 required.

 3. vswitch_ops: The ops is set of function pointers which are used to
 do operations
 like learning, unlearning, add/delete port, lookup_and_forward. The
 user of vswitch
 framework (vhost/main.[c,h])uses these function pointers to perform
 above mentioned
 operations, thus it remains agnostic of the underlying implementation.

 Different switching logics can implement their vswitch_device and
 vswitch_ops, and
 register with the framework. This framework makes vhost-switch
 application scalable
 in terms of:

 1. Different switching logics (one of them is vmdq, vhost/vmdq.[c,h]
 2. Number of ports.
 3. Policies of selecting ports for rx and tx.

---snip---

 FYI, I've reviewed this patch set, and it looks to me like there's 
some very good work here. Each patch in the set builds nicely on the one 
before, and logically introduces the changes one by one.

I've no functional suggestions as the implementation looks clean, 
but I've one or two tiny suggestions on headers and error messages. I'll 
add a reply to the relevant patches in the set.

Also, there's one or two issues thrown up by checkpatch, but I suspect 
they're false positives, as I'm using the 4.6 kernel version.

Regards,
Dave

[dpdk-dev] [PATCH v1]:rte_timer:timer lag issue correction

[Pattan, Reshma]

Hi,


> 
> For Periodic timers ,if the lag gets introduced, the current code added 
> additional
> delay when the next peridoc timer was initialized by not taking into account 
> the
> delay added, with this fix the code would start the next occurrence of timer
> keeping in account the lag added.Corrected the behavior.
> 
> Fixes:rte_timer: timer lag issue

Fixes line format is not corerct. Fixes line should contain  commit hash that 
introduced the bug and its subject line. For your case below should be added.

Fixes: 9b15ba89 ("timer: use a skip list")

Thanks,
Reshma

+Tun/Tap Poll Mode Driver
+
+
+The rte_eth_tap.c PMD creates a device using TUN/TAP interfaces on the local
+host. The PMD allows for DPDK and the host to communicate using a raw device
+interface on the host and in the DPDK application.
+
+The device created is a TAP device, which sends/receives packet in a raw format
+with a L2 header. The usage for a TAP PMD is for connectivity to the local host
+using a TAP interface. When the TAP PMD is initialized it will create a number
+of tap devices in the host accessed via 'ifconfig -a' or 'ip' command. The
+commands can be used to assign and query the virtual like device.
+
+These TAP interfaces can be used with wireshark or tcpdump or Pktgen-DPDK along
+with being able to be used as a network connection to the DPDK application. The
+method enable one or more interfaces is to use the --vdev=eth_tap option on the
+DPDK application  command line. Each --vdev=eth_tap option give will create an
+interface named dtap0, dtap1, ... and so forth.
+
+.. code-block:: console
+
+   The interfaced name can be changed by adding the iface=foo0
+   e.g. --vedv=eth_tap,iface=foo0 --vdev=eth_tap,iface=foo1, ...
+
+.. code-block:: console
+
+   Also the speed of the interface can be changed from 10G to whatever number
+   needed, but the interface does not enforce that speed.
+   e.g. --vdev=eth_tap,iface=foo0,speed=25000
+
+After the DPDK application is started you can send and receive packets on the
+interface using the standard rx_burst/tx_burst APIs in DPDK. From the host 
point
+of view you can use any host tool like tcpdump, wireshark, ping, Pktgen and
+others to communicate with the DPDK application. The DPDK application may not
+understand network protocols like IPv4/6, UDP or TCP unless the application has
+been written to understand these protocols.
+
+If you need the interface as a real network interface meaning running and has
+a valid IP address then you can do this with the following commands:
+
+.. code-block:: console
+
+   sudo ip link set dtap0 up; sudo ip addr add 192.168.0.250/24 dev dtap0
+   sudo ip link set dtap1 up; sudo ip addr add 192.168.1.250/24 dev dtap1
+
+Please change the IP addresses as you see fit.
+
+If routing is enabled on the host you can also communicate with the DPDK App
+over the internet via a standard socket layer application as long as you 
account
+for the protocol handing in the application.
+
+If you have a Network Stack in your DPDK application or something like it you
+can utilize that stack to handle the network protocols. Plus you would be able
+to address the interface using an IP address assigned to the internal 
interface.

[dpdk-dev] [PATCH 1/3] drivers/net:new PMD using tun/tap host interface

[Keith Wiles]

The rte_eth_tap.c PMD creates a device using TUN/TAP interfaces
on the local host. The PMD allows for DPDK and the host to
communicate using a raw device interface on the host and in
the DPDK application. The device created is a Tap device with
a L2 packet header.

[dpdk-dev] [PATCH v2 1/2] vhost: change the vhost library to a common framework which can support more VIRTIO devices

[Changpeng Liu]

For storage virtualization use cases, vhost-scsi becomes a more popular
solution to support VMs. However a user space vhost-scsi-user solution
does not exist currently. SPDK(Storage Performance Development Kit,
https://github.com/spdk/spdk) will provide a user space vhost-scsi target
to support multiple VMs through Qemu. Originally SPDK is built on top
of DPDK libraries, so we would like to use DPDK vhost library as the
communication channel between Qemu and vhost-scsi target application.

Currently DPDK vhost library can only support VIRTIO_ID_NET device type,
we would like to extend the library to support VIRTIO_ID_SCSI and
VIRTIO_ID_BLK. Most of DPDK vhost library can be reused only several
differences:
1. VIRTIO SCSI device has different vring queues compared with VIRTIO NET
device, at least 3 vring queues needed for SCSI device type;
2. VIRTIO SCSI will need several extra message operation code, such as
SCSI_SET_ENDPIONT/SCSI_CLEAR_ENDPOINT;

First, we would like to extend DPDK vhost library as a common framework
which be friendly to add other VIRTIO device types, to implement this feature,
we add a new data structure virtio_dev, which can deliver socket messages
to different VIRTIO devices, each specific VIRTIO device will register
callback to virtio_dev.

Secondly, we would to upstream a patch to Qemu community to add vhost-scsi
specific operation command such as SCSI_SET_ENDPOINT and SCSI_CLEAR_ENDOINT,
and user space feature bits.

Finally, after the Qemu patch set was merged, we will add VIRTIO_ID_SCSI
support to DPDK vhost library and an example vhost-scsi target which can
add a SCSI device to VM through this example application.

This patch set changed the vhost library as a common framework which
can add other VIRTIO device type in future.

[dpdk-dev] hw checksum offload feature issue

[Balasubramanian, RajaramanX]

Hi,

We are developing CGNAT VNF over DPDK. In that, we have NAT64 feature 
included which basically does IPv6 to IPv4 NAT translation and vice versa.

When we do conversion from IPv6 to IPv4, we have used dpdk mbuf library 
function  rte_pktmbuf_adj() to remove 20 bytes of IPv6 header at the beginning 
and create IPv4 header and other headers appropriately.

  Also, we have hw checksum offload feature enabled. So when the packet goes 
through NIC hw checksum, apart from calculating IPv4 and UDP/TCP checksum, it 
also modifies other header fields like eth header dest address field.

   SO, have you come across any issue like this ??

  When we disable hw checksum feature, packet header fields are not modified 
and there is no issue.

Thanks,
Rajaram.
