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

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

Yes. Please update the MAINTAINERS file as needed.
Chris Metcalf is out this week. I could submit a separate patch for the MAINTAINERS file if it's required. Or we could wait a little bit until Chris comes back.

Thanks,
Liming

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

2017-02-17 20:52, Chris Metcalf:

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.
