+
+AXGBE Poll Mode Driver
+======================
+
+The AXGBE poll mode driver library (**librte_pmd_axgbe**) implements support
+for AMD 10 Gbps family of adapters. It is compiled and tested in standard linux distro like Ubuntu.
+
+Supported Features
+------------------
+
+AXGBE PMD has support for:
+
+- Base L2 features
+- Unicast/multicast filtering
+- Promiscuous mode
+- Port statistics
+- TSS (Transmit Side Scaling)
+- RSS (Receive Side Scaling)
+- Checksum offload
+- Jumbo Frame upto 9K
+
+
+Supported Chipsets and NICs
+---------------------------
+- AMD 10 Gigabit Ethernet Controller
+
+
+Configuration Information
+-------------------------
+
+The following options can be modified in the ``.config`` file. Please note that
+enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_AXGBE_PMD`` (default **n**)
+
+ Toggle compilation of axgbe driver. To use axgbe PMD set this config parameter
+ to 'y'.
+
+- ``CONFIG_RTE_LIBRTE_AXGBE_DEBUG_INIT`` (default **n**)
+
+ Toggle display of initialization related messages.
+
+
+Building DPDK
+-------------
+
+See the :ref:`DPDK Getting Started Guide for Linux <linux_gsg>` for
+instructions on how to build DPDK.
+
+By default the AXGBE PMD library will be built into the DPDK library.
+
+For configuring and using UIO frameworks, please also refer :ref:`the
+documentation that comes with DPDK suite <linux_gsg>`.
+
+
+Prerequisites and Pre-conditions
+--------------------------------
+- Prepare the system as recommended by DPDK suite.
+
+- AXGBE PMD works only with legacy interrupts, so load igb_uio module in legacy interrupt mode
+ using module params.
+
+- Bind the intented AMD device to igb_uio module.
+
+Now system is ready to run DPDK application.
+
+
+Usage Example
+-------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Example output:
+
+.. code-block:: console

Hi Ravi,
This is a new networking driver from AMD. Great to see new vendors in
DPDK, welcome.
Patch 2/4 seems missing in the mail list, it may be stuck because of the
size limit if it is a big patch,
which may mean it needs to be split into multiple patches :)
Thanks,
ferruh

Hi Ferruh,
Thanks a lot. The Patch 2/4 got posted just now. It will be great to get review comments on the same.

At first glance:
- There is a new licensing, that needs to be approved.
- patch 2/4 is big and hard to review properly, is it possible to have
multiple incremental patches, there are good previous samples of this.
- Can you please update release notes to announce new PMD?
- ICC is giving build error [1], but this can be handled later.

Are these need to be public header? If not just delete above lines.

No more required, above drivers/net/Makefile update already does the
work, this can be removed.

You can use RTE_MIN, RTE_MAX

You can use rte equvalent functions, rte_read32 or rte_read32_relaxed
please check rte_io.h

This should be already done by rte_eth_dev_pci_generic_probe()

I meant following:
1. As a non-written convention, we are adding following statement in the
top of such dual licensed files : " This file is provided under a dual
BSD/GPLv2 license. When using or redistributing this file, you may do so
under either license.". And license header as "BSD LICENSE" or "GPL .."
2. you are using a modified version of BSD. Typical license in DPDK
files are BSD-3 or BSD-2. If you intend to use your specific version of
BSD license, it will require TechBoard, Gov Board and legal approval.
3. Additionally your BSD license is including a proprietary license text
of Synopsys. This will also need approval before it get included in DPDK.
4. It seems you have copy pasted the same license text in all the files.
e.g. do you intend to keep dual license option + Synopsys text for your
documentation and the files, which you have created originally for dpdk
only.

Also, there was a whitespace warning on the patch. Trim any trailing

Please keep us posted about your legal issues.
Maybe there is something we can help.
If you target 18.02, I suggest to send a v2 before the end of the month,
in order to give us time to review what else must be reworked.
Thanks

Thanks for following up on this.
The AMD legal team is working with Synopsys legal team on this as both the companies licenses are involved. Thats why it is taking longer than expected.
We are working hard to meet the month end deadline and want to target 18.02.

Ravi

HI Greg,
There is no restriction on sending the code to DPDK for public review and it is up to the respective maintainers to provide comments.
However, your patches can not be merged to DPDK and it's next trees till the Licensing issues are sorted out.

Hemant:
I am working the changes we are asking for on the BSD license. With respect to the Synopsys license text. They are telling me that similar header concerns were raised from linux .org and they were OK keeping the header if an author signoff-off text was included. Would that be sufficient for dpdk.org with respect to the Synopsys text?

HI Shippen,
DPDK is a BSD licensed projects unlike Linux kernel. BSD is very permissive license.
I am not a lawyer, I am just afraid that including a proprietary license should not have any implications on DPDK project. We are planning to move to SPDX based license identifiers to clearly mark file license instead of putting the whole license text in the source files.
1. We will need an statement from Synopsys that they agree to include this code as "BSD-3 clause" license.
2. In near future, you will be asked to remove the Complete License statement and the files will be identified under SPDK tag for BSD-3 Clause license (or Dual BSD-3/GPLv2). Note - your copyrights will remain intact.
If you don't agree to any of the above, we have to go to Gov Board for exception approval and may be to LF Legal for advice. It is going to take time.
Regards,
Hemant
