[PATCH osstest 00/10] Add initial support for testing arm32 on arm servers (Calxeda Midway)

[Ian Campbell]

Hi Ian,

The following patches add support to osstest for running ts-host-install
against a Calxeda Midway box.

I am running in standalone mode, I hope it will be easy enough for you
to integrate into the live system.

My .xen-osstest/config contains:
        HostProp_marilith-n4_Suite wheezy
        HostProp_marilith-n4_DIFrontend newt
        HostProp_marilith-n4_PowerMethod xenuse
        HostProp_marilith-n4_SerialConsole ttyAMA0
        HostFlags_marilith-n4 need-kernel-deb-armmp,no-di-kernel,need-uboot-bootscr
        
marilith-n4 is the Calxeda node. I have other stuff in my config too but
I think it all relates to standalone mode on my box rather than this
host specifically (stooge into ~ianc/.xen-osstest/config on the NFS home
dirs if you want a look, nothing private there).

With this I can run ./standalone-reset and then:
        OSSTEST_JOB=test-armhf-armhf-xl ./ts-host-install
        host=marilith-n4

Obviously this is just a first step. I'll be working my way down the
columns of http://www.chiark.greenend.org.uk/~xensrcts/logs/18778/ ...

I'm still not entirely sure how one defines a suitable column for armhf,
hopefully you can help when the time comes. For now I am going to look
at host-build-prep then xen-build. After that it looks like
xen-build-check and xen-install would be the interesting ones.

Ian.

The existing URL points to an unrelated patch, no doubt due to the accidental

[PATCH 04/10] mg-debian-installer-update: support armhf

[Ian Campbell]

The path to the installer differs on armhf vs amd64/i386.

Debian Wheezy does not contain kernels for the devices we want to support.
Therefore we download a kernel and modules from wheezy-backports which is new
enough.

This squashes the installers messages about not being able to find kernel

I've now gotten through:
OSSTEST_JOB=build-armhf ./ts-host-install host=marilith-n4
OSSTEST_JOB=build-armhf ./ts-xen-build-prep host=marilith-n4
OSSTEST_JOB=build-armhf ./ts-xen-build host=marilith-n4

apparently successfully. I think this means you could replace the
existing build test job running on the development cluster with a job
running on marilith-n5. I'd like to keep -n4 for osstest development for
now.

Which needs the following patch. Here are ipmi runes too if that fits
better with the non standalone version:

ipmitool -I lanplus -U admin -P admin -H marilith-n<N>-mgmt power on
ipmitool -I lanplus -U admin -P admin -H marilith-n<N>-mgmt power off

This sytem seems to need
ipmitool -I lanplus -U admin -P admin -H marilith-n<N>-mgmt chassis bootdev pxe
which doesn't appear to be sticky, so needs to happen each time.

I've no gotten as far as running ts-xen-install, which does some vageley
sensible looking things but Xen doesn't boot on the platform yet. It's
another tranche of 24 patches on top of this existing lot though. Rather
than spam the list (although I will if you like, or I can post
individual patch you would like to comment on upon request) I've pushed
it to a branch, which includes all the previous stuff too, pull request
at the end. This includes the runvar rework you sent me, I think there
was only one incremental fix which was "ts-xen-install: correctly
determine want_kernver and actually pass it".

I've ended up with a bunch of Wheezy related fixes in here too, all
mixed in I'm afraid...

With this I can do:
        # Clone trees into mygits with git clone --mirror --bare
        cat >standalong.config <<EOF
        export TREE_XEN=/root/git/xen.git
        export TREE_LINUX=/root/git/linux-stable.git
        export REVISION_LINUX=stable/linux-3.11.y
        export TREE_LINUXFIRMWARE=/root/git/linux-firmware.git
        EOF
        
        ./standalone-reset
        
        OSSTEST_JOB=build-armhf ./ts-host-install host=marilith-n4
        OSSTEST_JOB=build-armhf ./ts-xen-build-prep host=marilith-n4
        
        rsync -aH mygits/ root@marilith-n4:/root/git/
        
        OSSTEST_JOB=build-armhf ./ts-xen-build host=marilith-n4
        OSSTEST_JOB=build-armhf-pvops ./ts-kernel-build host=marilith-n4
        
        OSSTEST_JOB=test-armhf-armhf-xl ./ts-xen-build-check host=marilith-n5
        OSSTEST_JOB=test-armhf-armhf-xl ./ts-host-install host=marilith-n5
        OSSTEST_JOB=test-armhf-armhf-xl ./ts-xen-install host=marilith-n5
        OSSTEST_JOB=test-armhf-armhf-xl ./ts-host-reboot host=marilith-n5
        
Doesn't actually boot, but that's a Xen side issue I think.

Excellent, thanks.  Here's my review notes, from irc.

Ian.

16:25 <Diziet> ijc: Thanks :-).
16:25 <Diziet> I'll read them and maybe throw them in.
16:25 <Diziet> throw them in> Depends if I get a push of my switch to 3.4.y
16:28 <ijc> Thanks. I'm not totally convinced by the parameteriztion of the 
            consoles and stuff, if you have any better ideas please let me know.
16:29 <Diziet> It looks OK to me.
16:29 <Diziet> You mean the ttyS0 thing
16:30 <ijc> yeah
16:30 <ijc> if you are fine with it then great ;-)
16:31 <Diziet> That uboot thing ("New host flag need-uboot-bootstr") is a bit 
               full of magic, but it's ARM magic so I'll just take it I think.
16:31 <Diziet> Does the d-i pkgsel/include thing work on x86 ?
16:32 <ijc> it'll eventually need teaching about different arm and uboot 
            platforms. I think it'll do for now though
16:32 <Diziet> Or I guess, I mean, if u-boot-tools does not exist (which maybe 
               it doesn't on x86 squeeze)
16:32 <ijc> I thought it did, but I may be thinking of Wheezy
16:32 <ijc> there was a second transitional/dummy package now I think about it
16:33 <Diziet> "make an armhf flight" should be called "make some armhf jobs" 
               but no matter.
16:33 <Diziet> ijc: Hmm.  You might want to test that before I merge it and 
               complain.
16:33 <ijc> it was called uboot-envtools in Squeeze
16:34 <Diziet> So what happens if you mention an unknown package there ?
16:34 <ijc> I have no idea... I'll need to dig out an x86 box to test on I guess
16:34 <ijc> Or I could just make it conditiona;
16:34 <Diziet> Well, you could wait until I complain.  Right.
16:35 <Diziet> "PDU: support for xenuse controlled machines" has a mysterious 
               ipmitool rune in it which surely doesn't belong.
16:35 <ijc> oh, oops, that's peculiar to this machine
16:35 <ijc> which seems to have a oneshot pxe thing in its firmware....
16:35 <Diziet> Right
16:35 <Diziet> I think if "xenuse --on" doesn't work that means xenuse needs to 
               do the weird rune.
16:36 <ijc> xenuse --on would work though, just the system will boot from hdd 
            not pXE
16:36 <ijc> I have a feeling this is a firmware bug -- the docs suggest the pxe 
            thing should be permanent...
16:36 <Diziet> "TestSupport: Massage host props with space in them" can you 
               turn them to _ ?  Because I think we currently distinguish 
               "-"-aka-"StudlyCaps" from " "
16:37 <ijc> AH, I used - precisely so it would get further munged into 
            StudlyCps for consistency -- you don't want that?
16:38 <Diziet> Some existing property names are of the form "some-words 
               other-words"
16:38 <Diziet> - binds more tightly, in other words.
16:39 <ijc> ok
16:39 <Diziet> "ts-xen-install: wheezy has libyajl2 not 1" <- Does this work ?  
               Because qw() doesn't do $-interpolation.
16:40 <ijc> It succeeds but yajl isn't installed, I guess because the shell hid 
            the $yajl...
16:40 <ijc> For all these -- do you prefer I rebase or incrementally fgix?
16:41 <Diziet> You might as well incrementally fix, esp. since you seem already 
               to have merged.
16:42 <ijc> I can rebase -i -p if you prefer.
16:42 <Diziet> Nah.
16:42 <Diziet> Might as well have the history as you wrote it.
16:42 <Diziet> I don't think we need to stand on a nice tidy history in osstest
16:43 <Diziet> "ts-xen-build: allow per-host CONFIG_EARLY_PRINTK"   definitely 
               wrong
16:43 <Diziet> This should be done on the kernel command line.
16:43 <Diziet> Or maybe arch-specific.
16:43 <Diziet> You mustn't make the results of the build depend on the build 
               host like that.  Builds can get reused.
16:44 <Diziet> kernel command line> Which I think there should already be a 
               host property to add to.  If not there should be one created.
16:46 <Diziet> "$xenkopt" and "$kopt" in the bootloader setup code
16:47 <ijc> CONFIG_EARLY_PRINTK is a compile time option I'm afraid. It's 
            debug=y onlkly
16:47  * Diziet gets to the end.
16:47 <Diziet> How unpleasant.
16:47 <ijc> As I said in the comment, this is only really useful for standalone 
            builds
16:47 <Diziet> Surely even standalone things can build here and test there ?
16:48 <ijc> only really useful for standalone builds ... if you know what you 
            are doing
16:48 <ijc> I don't hitnk it is technically possible to make our earlyprintk 
            more flexible, it is used from before we have anything like an FDT 
            parser avaiable, from the early asm code
16:49 <Diziet> How annoying.
16:49 <Diziet> That's before the command line is read ?
16:49 <Diziet> Can it be binary-edited into the kernel image ?
16:49 <Diziet> A la that rootdev utility or whatever it used to be called.
16:51 <ijc> no, it defines asm macros which are inlined into the head.S code. 
            We can just revert that patch for oSStest, it was just conveinent 
            for me locally
16:52 <ijc> (it's start of day code which needs to be PIC and often has no 
            stack)
16:52 <Diziet> I guess we can leave it in, but can you put a comment near the 
               call to get_host_property warning about not setting it ?

I changed this to only add this package if the 'need-uboot-bootscr' flag
is set, which implies Wheezy or newer.

While I figure this out I made it conditional on a need-ipmi-pxe host
flag.

Done. I also capitalised the word so "some-words other-words" ultimately
becomes "SomeWords_OtherWords" not "SomeWords_otherWords".

Done. I have also left it deliberately unmentioned in README too.

Thanks.  This all looks promising.  However I did a make-flight and it
generated a test job "test-amd64-armhf-xl" which isn't going to work
very well :-).

Aside from that I think it's ready to merge in.

Looks good.  I have merged it and pushed the result to the pretest
branch (push gate input).  More news tomorrow...

Thanks,
Ian.

Did I remember to mention that this will need a newer kernel than is
currently the default? I bet I forgot.

I used v3.11 locally when testing but we'll soon need some fixes on top
of that. Anything older probably won't do the job.

Probably we need to maintain a specific branch to test against --
Stefano do you think you could set that up and maintain it?

I presume this will need some frobbing in make-flight to become true.

Ian.

See my bounce of the test report.  It passed the push gate as expected
:-) but of course the actual test failed.

Yes.

I guess we want a push gate for this too ?  What should the branch be
called, linux-3.11-arm-xen (with push gate output
tested/3.11-arm-xen) ?

> I presume this will need some frobbing in make-flight to become true.

Yes.  It's probably easier if I do that part.

The test was using army, the following would fix it I think but do you
need help on configuring some of the Calxeda nodes?

Right.  If you send me the config info for marilith I'll add it to the
db and we can see what comes out...

Applied, thanks.  (To osstest staging.)

I've been using:

HostProp_marilith-n5_Suite wheezy
HostProp_marilith-n5_PowerMethod ipmiextra on admin admin chassis bootdev pxe;xenuse
HostProp_marilith-n5_LinuxSerialConsole ttyAMA0
HostProp_marilith-n5_XenSerialConsole dtuart
HostProp_marilith-n5_XenDTUARTPath /soc/serial@fff36000
HostFlags_marilith-n5 need-kernel-deb-armmp,no-di-kernel,need-uboot-bootscr #,need-ipmi-pxe
HostProp_marilith-n5_Build_Make_Flags -j12
HostProp_marilith-n5_EarlyPrintk midway

marilith-n5 is available for osstest and is locked in xenuse for that
purpose. (osstest doesn't have a NIS user, so it is in my name)

I've been using it as a test host, but I can stick to -n4 for now. Once
I've ironed out the kinks osstest can have that one too.

I presume there is no problem, either in real or standalone mode, with
sharing the same host for build and test runnign?

Ian.

I think we are likely to want to ratchet through the 3.12 and 3.13
reasonably quickly in the short term.

How about we track mainline releases but not stable releases and instead
cherrypick fixes we need and merge new uptream versions when we want to
climb up? That would keep the tree non-rebasing. In that case I'd call
it linux-arm-xen in the hopes that one day it can be replaced by a linux
stable branch.

Stefano, do you think that would work?

That seems plausible.

Just let me know where the input branch is, and I'll set it up.

This is pretty ugly of course.  It will do for now.  For future
reference, if we want hacks like this they should be in the PDU
arguments, rather than a host flag.
