[PATCH 0/9] Add MIPS release 6 ISA support

[PATCH 0/9] Add MIPS release 6 ISA support

[Zubair Lutfullah Kakakhel]

Hi,

This patch series adds support for MIPS Release 6 ISA.

A few key points to note are:

1 - The tuples have changed for Multiarch. For details, check 
    https://wiki.debian.org/Multiarch/Tuples

2 - Dynamic linker loader name has changed.
    ld.so.1 -> ld-linux-mipsn8.so.1
    For details, check
    https://sourceware.org/glibc/wiki/ABIList#mips

I tested this using poky, krogoth-15.0.1, yocto-2.1.1 + various patches.
Most notable patches were adding support for Linux kernel 4.8 and using
4.8 headers. Preferred using 4.8 as there was a quirk in glibc + nan2008
that preferred 4.5+.
https://sourceware.org/ml/libc-alpha/2016-01/msg00240.html

Build + qemu boot tested for little endian variations.

Regards,
ZubairLK

[PATCH 9/9] arch-mips: Add mipsisa{32, 64}r6{el, } tunes

[Zubair Lutfullah Kakakhel]

Add support for MIPS Release 6 ISA and the various tune
configurations.

This patch adds the tunes for 32r6 and 64r6 n64 and not the n32
variants at the moment.

Release 6 onwards, the tuples are now
 - mipsisa32r6-linux-gnu
 - mipsisa32r6el-linux-gnu
 - mipsisa64r6-linux-gnuabi64
 - mipsisa64r6el-linux-gnuabi64
 - mipsisa64r6-linux-gnuabin32
 - mipsisa64r6el-linux-gnuabin32

For more details, check https://wiki.debian.org/Multiarch/Tuples

Re: [PATCH 0/9] Add MIPS release 6 ISA support

[Mark Hatle]

A few general comments.  I don't see an n32 variant implemented.  I'd suggest a
follow on patch (vs a new version) to add n32.

It looks like it's missing in the files modified by patches 6-9.

Otherwise I don't see any issues with adding the support for this new ISA.

Thanks for the review.
Yes I haven't added the n32 variant on purpose at the moment.
Wanted to get this out to see if this is the correct approach.

I've been torn on these patches, they're good but they've come in very
late in the cycle for this kind of change. Since they're comparatively
straight forward to review, I've merged them. This is partly because I
wouldn't really want to backport changes like this later and it seemed
likely that might be requested.

What I will say though is that we really need to think about an
"allmips", or "mipsarch" override, rather than all these duplicate
lines for all mips variants. This is something we should fix early in
the 2.3 cycle and should make some of this look a lot neater. It might
be worth openening a bug for this in the bugzilla and assigning that to
yourself, assuming you're happy to work on it?

Cheers,

Richard

Thank you very much for merging them this cycle!

The duplicate lines are bothersome indeed.
I'm happy to work on it. But I'm still a bit new to OE internals so would
prefer a little direction regarding the best approach to take.

Very roughly speaking, you'd add something like:

MACHINEOVERRIDES =. "mipsarch"

to arch-mips.inc then you could do:

diff --git a/meta/conf/bitbake.conf b/meta/conf/bitbake.conf
index 54a587f..7bd8716 100644
--- a/meta/conf/bitbake.conf

 TARGET_LINK_HASH_STYLE ?= "${@['-Wl,--hash-style=gnu',''][d.getVar('LINKER_HASH_STYLE', True) != 'gnu']}"

amongst other nice cleanups.

er, I do mean:

MACHINEOVERRIDES =. "mipsarch:"
