Re: [PATCH 0/4] catch up TILE-Gx support in DPDK

Hi Thomas,  All

Mellanox agrees to remove TILE-Gx support from DPDK.org, but will continue to support customers using DPDK. 
Customer that needs support should contact Mellanox directly.

Best Regards,
Olga

This patch series allows DPDK to build for TILE-Gx as of version 17.02.

A required library (libgxio) had not been made publicly available.
It is now available as source here:


http://www.mellanox.com/repository/solutions/tile-scm/libgxio-1.0.tar.
xz

it has also been folded into the binary release of the generic
toolchain that we periodically update on that website; for more
information about the toolchain tarballs, see here:

  http://www.mellanox.com/repository/solutions/tile-scm/

Note that the toolchain components were updated slightly in this
release of the tarballs relative to what was there before.

Thank you.
Some of these changes (being able to compile on a free toolchain) should
have been done since the beginning. Better later than never :) I think we
won't allow any new component in DPDK which cannot be built freely, in the
future (lessons learned).

Hopefully, with DPDK now working on TILE-Gx again, there may be
interest from someone in the community in taking on a maintenance
role.  At this point, the Mellanox engineering team responsible for
TILE-Gx is largely focused on working on future chips based on ARMv8,
so unfortunately we won't have much bandwidth for TILE-Gx support going

forward.

So do you mean that the TILE-Gx maintainers officially give up on their role?
Then please update the MAINTAINERS file.

If it still seems like removal makes sense now or at some point in the
future, it would probably at least be good to apply these patches so
there is a baseline to pick it up from later.

I agree. We can apply these patches before removing the whole
architecture.

Liming Sun, the tile dpdk maintainer, has reviewed these changes (he
sits next to me); if it's more appropriate, he can resend these
changes with his Signed-off-by as well.  I took on this work since I
was more familiar with libgxio and the details of our toolchain (I am
the maintainer for the tile architecture for Linux and glibc).

I think it is OK as is.
