buildbot for kvm.git

buildbot for kvm.git

[Avi Kivity]

Daniel, the buildbot has been fairly effective in keeping qemu-kvm.git 
building.  I'd like to extend that to kvm.git, especially for non-x86 
architectures.

I've now a virtual machine with a cross compile environment for s390, 
ppc, and ia64.  I'd like buildbot to build for the following archs and 
configs:

   x86_64: defconfig + KVM=m KVM_INTEL=m KVM_AMD=m
   i386: defconfig + KVM=m KVM_INTEL=m KVM_AMD=m
   s390: defconfig + KVM=m
   ia64: defconfig + KVM=m KVM_INTEL=m
   powerpc: ppc4x_defconfig + VIRTUALIZATION=y KVM=y KVM_440=y KVM_E500=n
                       KVM_EXIT_TIMING=n VIRTIO_PCI=m VIRTIO_BALLOON=m 
VIRTIO_BLK=m VIRTIO_NET=m
                       VIRTIO_CONSOLE=m
   powerpc: ppc64_defconfig VIRTUALIZATION=y KVM=y KVM_BOOK3S_64=m'
                       KVM_EXIT_TIMING=n VIRTIO_PCI=m
                       VIRTIO_BALLOON=m VIRTIO_BLK=m VIRTIO_NET=m
                       VIRTIO_CONSOLE=m

The recipe for a build is:
- check out the source
- MAKE defconfig
    where MAKE="make ARCH=$ARCH 
CROSS_COMPILE=/opt/gcc-4.5.0-nolibc/$ARCH-linux/bin/$ARCH-linux-'
- append the extra options to .config
- MAKE oldconfig
- MAKE

Can you help with this?

Note: the cross compile environments are from

in case anyone's interested.

Could we please also add an e500v2 build here? It compiles different MMU code.

Btw, thanks a lot for doing this!

Ok, will do as soon as I get into physical contact with my e500 box again. That will hopefully be by tomorrow :).

Currently I'm applying your recipe on the buildmaster configuration.

Beside that, buildmaster and a small x86_64 buildslave got setup and is 
available on:
http://buildbot.b1-systems.de/kvm/

Once I'm done with the buildmaster configuration (and some more testing) 
kvm.git continuous build testing could be ready within the next days.
(I'm travelling right now, but shouldn't block me to get this done)

If you like you can already setup the git post-receive hook in the kvm.git 
repo to trigger the buildmaster.

Like for qemu-kvm.git you need to copy git_buildbot.py (preferably a copy of 
the one which is used for qemu-kvm.git) and change the master-port to 9991
( master = "....:9991" )

In hooks/post-receive you add:
/path/to/git_buildbot.py $1 $2 $3

Thanks, done.

Will you set up crossbuilders for ppc/ia64/s390, or will I contribute a 
builder?

Later once the setup is stable it would be nice to have multiple buildslaves, 
so we get really fast response from the buildbot if a commit breaks something.

First test builds succeed for x86 and ia64:
http://buildbot.b1-systems.de/kvm/grid

with gcc-4.5.0-nolibc toolchain from
http://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.5.0/

powerpc not ready yet - trivial $ARCH change required in the buildbot
master configuration.

s390 compilation seems to run fine and hit the first compilation issue:
http://buildbot.b1-systems.de/kvm/builders/s390/builds/0/steps/compile/logs/stdio

Currently buildbot notification mails don't get send to the kvm list. I would like
to do some more testing before spamming with wrong-testing results.

Some more questions inline:

Any specific branches beside the master branch?

The buildbot master configuration requires exactly that path for CROSS_COMPILE on
the buildslave. The buildsaves need to be setup the toolchain before hand manually.

Just let me and Christian know if we should add another toolchain or upgrade to a newer one.

> - append the extra options to .config

Done this by invoking: ./scripts/config (proposal/attempt from Christian)

(See http://buildbot.b1-systems.de/kvm/builders/x86_64/builds/11/steps/configure_2/logs/stdio )

> - MAKE oldconfig

What about make target oldnoconfig instead?
To avoid that the build get stuck with every new config option?

Demo of the issue with "make oldconfig":

Will work on fixing it - so it's already useful!

I think buildbot has a mechanism where you can send it a patch to be 
build-tested.  This allows developers to build-test on architectures 
they don't have.  Can we activate this?

No, that's my old configuration I used for build testing.  While virtio 
isn't part of kvm, and is arch-neutral, it would be good to enable it.

I think this is fine.  Hopefully we won't upgrade too often, this should 
last us a year or two.

I used 'make oldconfig < /dev/null', wasn't aware of oldnoconfig.

Thanks for doing this!

Sure. Just enabled that. Actually it's also available for qemu-kvm.git but 
never really got used.

Who should get access to this? I wouldn't make it available for anonymous, 
since someone could checkin an "evil"-patch for a makefile, which includes "rm 
-rf /this/and/that" and vanish the buildslave. 

I'm fine giving (personal) user accounts away for people who just ask for it. 
Or do you want to make this only available for a small (trusted) group?


Try-Build would get triggerd with the buildbot command (on developers 
workstation) like this:

$ cd kvm.git
... do some changes ...
$ buildbot try --vc git -c pb -m buildbot.b1-systems.de:8033 -b s390 \
  -u $USER --passwd=$PASSWORD

Ok. I see - was just wondering because it was set in your powerpc 
configurations but not for others.

done.

On the next kvm.git push the buildbot should trigger a build test for 
branches: master and next.

I think you can give accounts to kvm contributors (present in kvm.git 
commit log).  I'll start asking people to build-test and point them at 
you for accounts.  Should be rare though, most commits are x86 specific.

I'll start by asking for an account.

Ok.

> 
> I'll start by asking for an account.


Unfortunately we're running (in meanwhile) an old version of buildbot as 
buildbot-master (0.7.8, as shipped by Debian 5). And there seems to be an 
issue using a recent buildbot version to trigger a "try"-build (e.g. 0.8.1) . 
Everyone would have to downgrade to buildbot (client) 0.7.8, even if their 
distro ships a more recent version.

Another (minor) issue with the old buildbot-master is that every time someone 
performs a try-build of a patch the buildbot-slaves will vanish the source-
directory on the next testrun. And perform a complete git clone from scratch, 
which wastes some minutes of testing time and a lot of traffic. Need to check 
more recent version of buildbot, lots of stuff got changed/rewritten when it 
comes to VCS handling.

Newer buildbot version also support now "GitPoller" to detect new changes. So 
we can avoid the rsync-git.kernel.org-delay issue.

So there are lots of reason to look into new buildbot version, before giving 
away try-accounts.

FYI, ppc44x is finally building (uboot-mkimage was missing on the slave).
Continuous Testing for all requested architectures and the master and next 
branch should work now. Will add the kvm mailinglist tomorrow to the 
notification list for build-failures of kvm.git.

Once I reviewed the newer buildbot version I start providing the try-accounts.


Best Regards,
Daniel

Last time I checked (quite a few moons ago, though), that version
contained an unfixed security issue. I installed a vanilla version on my
server for that reason (and forgot to patch that afterward...).

Are you talking about this one?
http://buildbot.net/trac/wiki/SecurityAlert0711

We applied that patch already.
Are you aware of any other unfixed security issues?

Best Regards,
Daniel

Not that I recall.

The point was just that, if I already have to patch the package, then I
could also use a more recent version.

powerpc builders are now also setup and already spot something.

Same bug as the one of the S390 ones.

Avi, my (whitespace broken) patch for this is:

Have you fixed this locally in your tree already or do you want to pull from me?

I don't have this locally.

error compiling committee.c: too many arguments to function

buildbot for kvm.git is now live (was: Re: buildbot for kvm.git)

buildbot for kvm.git is now live and is build-testing the master and
next-branch for i386, x86_64, ia64, s390, ppc64, ppc44x.

Continuous build-testing is triggered by a git receive hook and a nightly
build scheduler. And will notify directly to the kvm list on any build issue.

In near future we will provide access for easy test-building your patches via
the buildbot across all available architectures.




The builders spot a recent regression for non-x86 in the next-branch.

common issue across all non-x86:

... error: 'struct kvm' has no member named 'tlbs_dirty'


s390:   http://buildbot.b1-systems.de/kvm/builders/next-s390/builds/3/steps/compile/logs/stdio
ppc64:  http://buildbot.b1-systems.de/kvm/builders/next-ppc64/builds/2/steps/compile/logs/stdio
ppc44x: http://buildbot.b1-systems.de/kvm/builders/next-ppc44x/builds/1/steps/compile/logs/stdio
ia64:   http://buildbot.b1-systems.de/kvm/builders/next-ia64/builds/2/steps/compile/logs/stdio


Good: 9ee00410d82a7c5cab5ae347d97fbf8a95c55506

Enjoy the buildbot!
