As Dave said, we rely on others to do ARM testing for the most part,
though I've certainly jumped in and debugged some issues from time
to time.
It'd be super if Fedora could run the xfstests test suite on arm
as part of QE. I'd be more than happy to help get that started
if people are interested.
I don't know that Fedora QA has the resources to do this, but I'll cc the Fedora
test@ (QA) arm@ lists. If these are highly automatable tests it might be possible, if they
have the hardware. More likely I think it's that we need some ARM community folks to
look at splitting up some of this work.
I'm not sure yet what concerns the ARM group might have with XFS either as this
hasn't been decided, but the Fedora Server product working group is slightly leaning
toward XFS by default. Performance and CPU hit wise on x86_64, XFS seems to match up well
with ext4 and maybe even a bit better ratio of throughput/CPUtime for booting workload
(systemd is parallel!) so if were the same on ARM XFS could work out slightly better for
them.
