[PATCH] libpng 1.6.13: fix build for aarch64

[Koen Kooi]

The configure override was too restrictive, it needed both 'arm' and 'neon' to trigger, which breaks on aarch64. Since TUNE_FEATURES is the only qualifier that matters, drop the 'arm' override.

Buildtested for 'genericarmv8' and 'qemux86' machines.

Kai was collecting patches that were sent to oe-core, and this may have
been one of them.

Is this some new requirement for OE-core patches?

Its someone being helpful and trying to consolidate a topic branch and
test things before it gets merged.

So its not a new requirement but it is helpful and appreciated.

It's been over a month and libpng is still broken, so I refuse to classify this new process as 'helpful' or as 'appreciated' at this point. 

If this continues can the person doing such a branch reply to patches intended for it saying they will or won't be queued? And please run the patches without such a reply through the regular process. That would be both helpful and appreciated.

Remember that 1.7 was frozen solid for several weeks of that month, so no
it wouldn't have been merged in that time period.  It's only just
re-opened: master is currently 80 patches ahead of dizzy, 35 in the C-Pull
I sent last night, and another 33 in my staging branch right now so it's
not like we're taking it easy right now.

Some context: during September it was obvious that various parties had an
interest in aarch64 (Linaro and Wind River).  Patches to fix build failures
were being sent sporadically, a qemuarm64 machine was submitted, but there
was no kernel for said machine to actually build.   At the time there was
no qemuarm64 machine that actually worked, so even merging the "simple"
fixes on just faith that they're correct would be reckless considering we
were freezing.  This is why I suggested[1] that someone with a vested
interest in aarch64 collate all the patches into a single branch and keep
it rebased to master so that when master opens, it can be tested on *all*
qemu architectures and merged.  It appears that this hasn't happened.  Will
Linaro be able to create a branch that incorporates all of the patches and
new machine that's been tested as a whole?

Most likely not because we already have meta-aarch64 for the toolchain and kernel support. But aside from that, the past few *years* it wasn't a problem to get aarch64 related patches merged into OE-core, so why is there suddenly such a problem now?

Furthermore, this libpng patch isn't strictly an aarch64 patch, it fixes a previous commit that should have been flagged in review as being wrong for using double qualifiers in a bogus way. So why did the culprit go in and the fix submitted 3 days later not?

Because oe-core was frozen and we were only taking serious fixes.  Now
there's a number of related patches that can and should be bundled up so
they can be tested as a whole.

That patch in particular?  Because humans are not infallible.  FWIW, this
is in my MUT now.

Well, for the past month we've been freezing for and working toward the
release and it was agreed this batch of patches were being queued for
post release. I think that was quite clear.

As you well know, partly this is because we don't have a way to test any
of it, nor is it an officially supported target. If we get a consistent
set of code and a qemu machine that can test it, we'll be in a better
position and I believe that is something people are working towards (but
was way too late for the 1.7 cycle).

We're now in a position where we've started merging patches again, there
is a backlog being worked through and I'm sure this batch will be
presented soon. We are sticking with the stated plan which was to have a
queued branch of those patches, until such times as there is a better
plan or offer.

It would be nice if the folks at Linaro would actually present things
like a branch containing theire changes and help with this work. As it
is, it seems others need to do this for them and instead they just want
to complain why we don't take patches (which often don't even seem to
build). I can understand not everyone at Linaro is going to test patches
on a couple of other arches but having someone there aggregating patches
and doing some acid tests might massively improve both their reputation
and increase the chances of patches merging in a timely fashion.

Cheers,

Richard

We've been attempting to aggregate what we (WR) can in:

  http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=kangkai/qemuarm64

But as it's unofficial and we're simply trying to keep the patches we know of 
together..  you'll have to be patient.  The first order of business is getting a 
functional qemuarm64.. it's MOSTLY there, but we're having toolchain issues and 
other things that are simply higher priority for us.

As for libpng, we have a different version of the patch in that branch...  it 
was enough to get around the problem in question, but may not be the correct fix.

Great, thanks Mark.  A functional qemuarm64 that boots core-image-minimal
is a good step in the right direction, then we can experiment with it on
the autobuilder. :)

There will be a few more patches from Mark for multilib, then we could 
build it on autobuilder. I'll finish it today.

Ping, libpng is still broken and I'm still not clear why this bugfix hasn't been applied for the past 3 months. I'd like to get this in so it can be backported to dizzy ASAP.
