Greetings ! Any Ideas/steps of how to  porting gentoo on  ppc64le
architecture?

Is it that we should add 'ppc64le' keyword to portage ?


As some of you might know,  Ubuntu has been introduced in support of
ppc64le. <http://www.ubuntu.com/download/server/power8> ! It's just as it
 sounds  ppc64( 64bit only ) but little endian. I've been made basic chroot
environment  in my
Ubuntu 14.04 ppc64le manually, the packages was built  and you can see here
for detail:
https://bpaste.net/show/e99035777057

And another way how to porting is: https://wiki.gentoo.org/wiki/Porting

Please let me know forward/steps to port gentoo on ppc64le.

Appreciated your thoughts, comments and efforts on it ~~~

I'm not on the ppc team but I do some ppc(64) testing for Java
packages. Although these are relatively well-maintained keywords
overall, I think the team would struggle to cope with an additional
one. It's also important to note that while ppc and ppc64 can be tested
on the same hardware, I think ppc64le would require different hardware?
If ppc64le does become popular then I would suggest that we drop 32-bit
ppc first. Others may disagree though. :)

I think ppc64le would become popular,  https://en.wikipedia.org/wiki/Ppc64.

1. enable porting x86 Linux based application with minimal effort.
2. Some PowerPC user, little endian apparently feels cheap, wrong, and
PCish.
3. Other distrbutions like Ubuntu, Redhat and SUSE already support little
endian in powerpc.

In terms of the codepaths, what's different between ppc64le vs ppc64,
and ppc64le vs amd64 ?  Obviously kernels will differ, but in terms of
C/C++/other compiled source code what needs to change?

If all this needs is its own profile for a CHOST/CBUILD specification
and it can leverage an existing keyword, then this should be rather
simple to implement yes?

I spoke to blueness in #gentoo-powerpc and he basically said the same
thing, that the existing ppc64 keyword should suffice. He noted that
we do not have different keywords for every mips variant because that
would be a lot of keywords! Stage 3 tarballs (possibly cross-compiled)
could be provided and some initial work could be done to ensure they
actually function but beyond that, endian issues would simply be dealt
with as they are reported.

We would leverage this on ppc64 keyword.  It is a bit dangerous to claim 
that a pkg stable on ppc64 is stable on ppc64le, but we would live with 
that risk.  Ideally you should test on both.  The situation is analogous 
to mips where there are many different ISAs and both be and le.  It is 
one of the reasons mips is hard to move back into stable.  But having 
stable keywords is really nice when it comes to building and maintaining 
stages and keeping base pkgs versions in sync with the other arches.  
For this reason, I would even been in favor of restoring stable mips 
with the understanding that "stable" carries something of a risk when 
crossing the be/le boundry, or the mips I vs mips III, or 32 vs 64, etc.

Having said that, what would break?  Assembly and other code that makes 
assumption about byte order.   There is some out there, but not much.  
We'll deal with it when we hit it.  Any of the heavy duty stuff, like 
syscall interfaces or setjmp/longjmp etc, should be relegated to the 
libc and kernel.

yes, we should just re-use the existing KEYWORDS and control the endian
differences via profiles.  it's how other arches (mips, ppc, arm, arm64)
are handled currently.

note: people have already built Gentoo for ppc little endian, but that
tends to only be used in embedded setups, so the builds don't get published
like other arches as stages.

1.   I have successfully complied ppc64le chroot environment manually.
      General Steps that omitted modify USE flag are here.

https://docs.google.com/document/d/1zGO5Gvu4DGPX7Pn70q5vbW_uF___4h8_pIpOtoOEdnY/edit?usp=sharing

2.  How to control endian difference via profiles ? i.e.  *How to get
ppc64le as a full stage/profile along side ppc64* ?
     Could you give me in detail ?

3.  ppc64 already have stage3,  why ppc64le tends to only be used in
embedded setups ?  If embedded setups, please
     let me know any forward/ steps .
    http://distfiles.gentoo.org/releases/ppc/autobuilds/current-iso/

4.  I would like become a developer of porting gentoo on ppc64le.  Anyone
could help/mentor me to join this project ?
    https://wiki.gentoo.org/wiki/Project:PowerPC  appreciated your
assistance and help.

5.  https://wiki.gentoo.org/wiki/Porting   The Section 'Converting to

you probably want to create a new profile dir:
	profiles/arch/powerpc/ppc64/little-endian/
then add a make.defaults file with the right CHOST defaults.  as we find
packages that have problems on little endian, that provides you a safe
space to mask features too.

then create a new target for linux users:
	profiles/default/linux/powerpc/ppc64/13.0/64bit-userland/little-endian/
that'll inherit the arch/powerpc/ppc64/little-endian parent

i said "ppc little endian", not "ppc64le".  historically speaking, ppc64le 
hasn't been a thing, and the only people doing ppc little endian are 32bit
embedded users.  that doesn't mean we can't make stages/iso for both.

ideally someone on the ppc side would pick you up, but i think they've been
a bit of a skeleton team of late.  so if need be, i can help you here.

you mean my bootstrap-portage script ?

do you have hardware ?  then it's simply a matter of booting Gentoo in it and 
filing/fixing bugs :).

We should also start building stage3s.

Appreciated your efforts and comments.

1.  We've successfully compiled stage 3 for  ppc64le. The stage 3 covers
most useful functionalities:

   - GNU tool chains. e.g. automake, autoconf, gcc & glibc.
   - Normally use Portage, e.g. emerge, ebuild & python
   - Normally chroot in this stage 3.
   - Not included linux kernel & bootloader yet.

2. We believe to make Gentoo support ppc64le, we still need to compile
kernel and bootloader

   - Which version of kernel provided by Gentoo would you suggest us to use?

          As to Ubuntu, there will be many patches to make the kernel
workable, so how to patch
          our Gentoo kernel  to make it work for ppc64le?

   - Which version of grub suitable for ppc64le ?  Is there any patches to
   ppc64le grub ?

3. When the gentoo we make out workable on ppc64le, we would like to know
the process of
    making it officially supported by Gentoo community

   - For each arch, do we have a subteam to verify the packages? If so, how
   to reach these guys?
   - For hardware environment, does anyone have Power8 systems ?

...usually a gentoo installation requires you to build the kernel
and bootloader yourself, inside of the chroot.  Is this something
that isn't possible?  Or is the requirement related to a live-boot
medium rather than the installation image?

There appears to be at least partial support on the master branch upstream.

Also, take a look at the grub-devel mailing list archives; there have
been several proposed patches within the last year.

We do not have an IBM contact (that I know) otherwise I'd love to get 3
powerdev minimal paravirt enviroments to test BE, LE and Power7.

Anybody with ties with IBM willing to help? =)

I have applied to osuosl for an ibm power8 ppc64le node.  I've put 
myself down as the point-of-contact.  I asked for openstack gui access 
and will try to build a system using Leno's stage3.  I'm not sure what 
the env looks like right now, but i assume i'll have to boot off a cd 
image.  I'll use debians.  I guess I could be macho and try to build 
everything from scratch, cross compile a kernel and all, but  .... time.

Has anyone tried qemu simulating ppc64le on amd64?  Lu I thought you 
said you tried on x86 and it didn't work.

Hi Guys， We have finish compiling stage3 for ppc64  (little-endian).Here is
the link:

https://drive.google.com/file/d/0B2k84p6709AyTFlwLUF1WjlxUk0/view?usp=sharing
 Now we are going to build LiveCD using stage3.  Could you help to give
some demo or a guide for building LiveCD? That will help we a lot to make
effort.
Thanks ~

   stage3s for ppc64, or ppc64le ?  If its stage3s for ppc64le, that's
perfect to work together.

But I still quite confused about the CHOST, such as if I couldn't compile
"sandbox" successfully in this method, however when I tried to use ppc32's
profile, it builds well without any errors (similar situation of other
packages on ppc64's profile as well). What's that mean? how to fix this?
Could you give me some details ?

w/out error messages it's hard to guess at what the problem is you're seeing.

YES. We have KVM virtual machine of ppc64le.  Can we booting/filing/fixing
by KVM ?

Greetings !~~


*What I have done according to your suggestions.*

Once you have these packages, you can easily install Portage.

root #wget http://distfiles.gentoo.org/distfiles/portage-2.2.20.tar.bz2
root #tar -xvf portage-2.2.20
root #cd portage-2.2.20 && python setup.py install



1, sync up and we should have our Portage tree!

root #emerge --sync

Then we need to create a new  profile for the new architecture  ppc64le:

root #cd /usr/portage/profiles/arch/powerpc/ppc64/ && mkdir little-endian
root #cd little-endian
root #echo '..' > parent
root #cat << EOF > make.defaults
CHOST="powerpc64le-linux-gnu"
EOF


2, create a new target for linux users:

root #cd
/usr/portage/profiles/default/linux/powerpc/ppc64/13.0/64bit-userland/
root #mkdir little-endian && cd little-endian
root #cat << EOF > parent
..
../../../../../../../arch/powerpc/ppc64/little-endian
EOF
root #cd /etc/portage
root #ln -s
../../usr/portage/profiles/default/linux/powerpc/ppc64/13.0/64bit-userland/little-endian
make.profile
root #cd /etc/portage
root #cat << EOF > make.conf
PORTDIR_OVERLAY=/usr/local/portage
MAKEOPTS="-j8"
CFLAGS="-mcpu=power8 -mtune=power8 -O2 -pipe -I/gentoo/usr/include
-L/gentoo/usr/lib64 -L/gentoo/lib -L/gentoo/lib64 -lpthread "
CXXFLAGS="${CFLAGS}"
CPPFLAGS="${CFLAGS}"
LDFLAGS="-I/gentoo/usr/include -L/gentoo/usr/lib64 -L/gentoo/lib
-L/gentoo/lib64 -lpthread "
LC_ALL="en_US.UTF-8"
FEATURES="buildpkg"
USE="python_targets_python2_7"
EOF


3, Fix Problem with sandbox

root #apt-get install pax-utils build-essential gawk
root # emerge --nodeps  --ask sandbox


4, Build the whole system

root #ROOT=/gentoo emerge @system
Results: https://bpaste.net/show/e6db5a5a70aa


           Should `ROOT=/gentoo emerge glibc`  or `ROOT=/gentoo emerge gcc`
first to fix the circle dependencies ?
           Please let me know forward/steps to port gentoo on ppc64le.

 /etc/portage/package.accept_keywords  in ppc64le and bug reports as
following links.
>=dev-libs/libffi-3.2.1 ~ppc64

KVM is fine.  i'm assuming you can't boot a ppc64le vm when the host is
ppc64be ?  i don't think any Gentoo dev has access to ppc64le hardware,
so we'd rely on ibm to fix bugs and such.

We can boot ppc64le by KVM on POWER7  (abbrev. PowerKVM)
and KVM on Power7 is big endian. If you have real POWER7 hardware,
you can install Ubuntu or RedHat ( integrated with KVM by default) on
POWER7.

As above, we can boot ppc64le by KVM on POWER7. Is not mean that we can
booting/filing/fixing by KVM? If so, i'll try to get some KVM virtual
machines :-)
