I've reorganized the commits per family of drivers,
so it makes more sense than grouping per driver class
with "common/octeontx" for title for all:

net/thunderx: enable build only on 64-bit Linux
common/octeontx: enable build only on 64-bit Linux
common/octeontx2: enable build only on 64-bit Linux

and applied.

Actually not applied yet.
I'm not sure what to do for the ABI check which is broken
because some drivers are not compiled anymore in 32-bit build.
I've workarounded locally by removing the dump files in the reference build.
Should we add an exception in libabigail.abignore?

In the past we said that depreciating HW support would be considered to be same as an ABI Breakage.

From the policy ... 
"Updates to the minimum hardware requirements, which drop support for hardware which was previously supported, should be treated as an ABI change."

So the patches should wait 21.11.

Looks good to me to postpone.

@Ray Kinsella @Thomas Monjalon  @McDaniel, Timothy @David Marchand @Neil Horman

Currently, I merged DLB v1 driver removal patch to next-eventdev. Is
this ABI breakge[1]?

http://patches.dpdk.org/project/dpdk/patch/20210316210812.15614-1-timothy.mcdaniel@intel.com/

[1]
From the policy ...
"Updates to the minimum hardware requirements, which drop support for
hardware which was previously supported, should be treated as an ABI
change."

Is +1 for not to remove the dlb driver or remove it?

You'll note the original reply pointing at the ABI Policy was from myself.
So I would be in favor of retention until 21.11. 

Thats said...

We should think about making the rules less strict for 32bit in future, from 21.11 onwards perhaps.
How many OS Vendors are shipping 32bit OSs these days for example?

We need a deprecation notice.

Agree on 32bit.

The DLB driver removal patch from @McDaniel, Timothy
http://patches.dpdk.org/project/dpdk/patch/20210316210812.15614-1-timothy.mcdaniel@intel.com/
is deleting the complete driver. So it does not look like it is
updating the minimum HW requirements
as mentioned in the policy.

So IMO, it is OK to accept his patch for 21.05(ie. remove the driver).
Let me know if there is any objection on this?

There were a couple of cleanups (indent etc..) and changes in meson files.
This series does not apply cleanly on the main branch.
Could you rebase it?

I noticed that the net/cnxk driver does not have this check, but it is
disabled anyway since it depends on common/cnxk.
Is it worth adding the check for consistency?

Hi Pavan,

Isn't it possible to provide a commit log in the kernel side etc, that let
others to verify why only 64 bit is required, or if someone want to support
32bit that may help them to investigate the source of the restriction.

[dpdk-dev] [PATCH v6 3/3] common/octeontx2: enable build only on 64-bit Linux

[pbhagavatula]

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Since AARCH32 extension is not implemented on octeontx2 family, only
enable build for 64bit.
Due to Linux kernel AF(Admin Function) driver dependency, only enable
build for 64-bit Linux.

Hi Pavan,

Perhaps this patch took more time than it should, but according Jerin's
description the problem is SoC can't run 32bit applications.

Why do you still mention from the kernel driver dependency? It looks like
that dependency is not reason to not compile 32 bit app, am I missing
something?

Since DPDK runs on FreeBSD and Windows and AF driver is absent for those
We are disabling this driver non-Linux compilations too.

Ah, it doesn't only add 'RTE_ARCH_64' requirement, also reduces the support
to Linux, so commit log makes sense. Thanks.
