OS to run on Sparc h/w, with a gui. I would be quite happy with Sol
10, but Oracle support licenses are too expensive.
Old it may be, but even Squeeze is pretty stable. Just wanted to try
out a later version and afaics, 7.10 was the last supported stable
release.

if netbooting is an option for you, installation report
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=757787 may help you.

Probably the mentioned netbooting stuff is already moved to an debian
archive after the official end of wheezy support now.

Good luck,

Herman,

Thanks for the info. Have never used netboot, so will give that a
try, We all get stuck in loops from time to time and I need to test
7.10 and gauge what state it's in to be able to move on.

One of purposes of the exercise is to survey available operating
systems for Sparc. It seems that many Linux distros have ended support
while other OS, for example, FreeBSD is still being developed, but it's
a tier 2 architecture and not as complete out of the box as 386 / amd64
versions. No problem for the experienced user, but steep learning curve
for the less experienced and it's difficult to find the info to solve
problems. More installs are needed to gain the critical mass to
spawn more developers, but unless there are stable versions, how is
that to be encouraged ?,

Anyway, thanks for the help and hope Debian thrives. Don't have the
knowledge base to contribute code at present, but will try to keep up
to date with the list and may be able to contribute something from
time to time...

Regards,

Chris

The main reason most distros removed support is that sparc information died right around the time Oracle purchased sun. Oracle stopped providing open hardware information. Sun lacked in this department too, but at least they made it available. Kernel support stagnated and new machines didn't work.

You also had datacenters abandoning sparc gear as fast as possible. A lot of open source companies adopted sparc gear to aid with OpenSolaris and help port linux. That died as soon as Oracle closed source Solaris development.

Only recently has oracle started submitting patches to linux for SPARC support (Started around kernel 4.1). Because of that you are seeing a few people start working again on porting efforts as we now have some decent hardware support in the kernel.

FreeBSD has suffered from the same problems too. sparc support was actually being considered to be dropped due to incompatibilities with clang. Luckily that was remedied. Even though, FreeBSD still has no sun4v support, so any machine newer than roughly ~2008 wont boot FreeBSD. OpenBSD has support for these machines, and i've looked at porting it in the past, but it will be quite a bit of work to say the least. Unfortunately my knowledge of BSD internals lacks compared to linux, so i put that project off until a later date. Or unitl someone else steps up to the plate.

I wish sparc was better on linux, you're just a little too early to the game unfortunately. Only debian and gentoo have anything roughly working, it remains to be determined as to whether anyone else will step up to the plate.

The good news is that if Oracle Linux makes official releases for sparc at some point in the future (very likely), porting CentOS to sparc should be quite easy. So i imagine in a year or so there will be quite a few more players on the field.
