How to troubleshoot aarch64 and s390x?

[Richard Shaw]

I'm working on building the new openexr package but the unit tests are
failing but just on aarch64 and s390x.

The aarch64 test instances are down due to the infra move and there are
none for s390x.

What's the best way to work around this? An emulated aarch64 install of
Fedora?

Thanks,
Richard

I tried qemu using this link but it's wildly out of date...

https://fedoraproject.org/wiki/Architectures/AArch64/Install_with_QEMU

I updated the url for Fedora 33 but it still fails...

sudo virt-install --name f33-aarch64-urlinst --ram 4096 --arch aarch64
--boot uefi --disk size=8 --location

Updating the url to aarch64 should work. 

sudo virt-install --name f33-aarch64-urlinst --ram 4096 --arch aarch64 --boot uefi --disk

I may use a raspberry pi for testing aarch64 applications, or if
downloading fails for some reason, maybe it could be possible to
download those files in advance and specify a local path?

And if having problems with s390x,
https://linuxone.cloud.marist.edu/
provides a free s390x vps (at least last time I used its service)

Yeah, sorry about that. ;(

So for aarch64, perhaps we can (at least until we get our machines back
online) spin up some amazon instances as test machines. 
Filed a ticket for that: https://pagure.io/fedora-infrastructure/issue/9541

s390x is harder. ;( I see downthread someone pointed to a ibm place that
can provide them. I wish we could.

I believe we can get a dedicated VM for Fedora, so it could be listed at
the "test resources" wiki page. It's on my to-do list. For individual
needs please contact me.

Just to (not quite) wrap up this thread...

Someone reached out to me privately to provide some hardware that can run
Fedora aarch64, so once I receive that my immediate need should be
satisfied assuming the same problem is plaguing it and s390x which is an
assumption at this point.

I'll take a look at the IBM community stuff while I'm on holiday after this
week which may also be a stop gap.

Thanks,
Richard

It's probably limited to a short trial period or something. You'll 
probably find it lot easier to work with Dan Horak instead. ;)

can confirm that Dan's s390x machine is a fast path to fixing
s390x breakage.

Because I completely forgot about that thread. We should
definitely document it somewhere easy to find.

Well, it only took a little over 5 hours for one build attempt, but it
worked!

And that was on my decent desktop machine AMD Ryzen 5 3600.

If you don't mind spending some money then Raspberry Pi 4 is a very
capable Fedora machine these days:

I've been watching progress on that in the Fedora ARM list and also on the
BackupPC mailing list. It looks promising but not quite ready just yet and
I've seen some reports of design flaws causing issues as well.

Regardless I was gifted a Nvidia Jetson Nano which helped me solve the
problem. Well, not quite solved, but it's in upstreams hands now.

Thanks!
Richard
