Hi David,
Firstly, thanks for caring about ports architectures!

Other than generally not being the same processor, and landau having many more
threads (it uses parallel=32, since there are 4 concurrent builds over 128
threads), there is one potentially important difference; the UltraSparc T1 on
andi uses a 48-bit virtual address space (with any returned addresses being
sign-extended), whereas the T5 on landau has a 52-bit virtual address space. It
could also be something completely different, too, of course.

What machine were you trying to reproduce it on? The sparc64 porterbox, notker,
also uses a T1, so if this is the problem you won't be able to reproduce it
there.

Regards,
James

openjdk-8 build failure on landau, unable to reproduce locally

[David Matthew Mattli]

Several of the last openjdk-8 builds have failed with a segfault[0] but
I haven't been able to reproduce the failure locally. Looking at the
list of build logs[1] I noticed that the last successful build was by
andi on 2016-12-12. All eight of the landau builds failed with a
segfault.

Given that I can't reproduce the failure and andi seems to be able to
build openjdk-8 successfully is it possible that landau has an issue?

Thanks,
David

Hello there!

I have SUN UltraSparc 1 machine and no SCSI cdrom. I can install Debian 7
by DHCP/TFTP (using boot.img). How can i install Debian 9 port to sparc64?
Of course, i can install Debian 9 by qemu-system-sparc64 and use dd to copy
on real HDD, but it very slow.
