What kind of MIPS hardware do we have? (Looking to restart Gentoo/MIPS, need info)

Hi,
I'm going to be working on Gentoo/MIPS. I'm planning to provide N32
stages, and I want to know what kind of MIPS hardware people have to
run Gentoo. With this info, I should be able to better prioritize the
tasks.

So please reply with what kind of hardware you've got.

Thanks!
Matt

Hello,

i am running two systems with Gentoo:

- a R14000 SGI Octane (IP30)
- a RM7000 SGI O2 (IP32)

So, obviously, im kinda interested in SGI/Mips-Gentoo....

Thank you for all the work, btw.

Michael

(Very) unfortunately this is a bit out of my ability-level. The port
for the O300 (IP35) hasn't ever been completed. O300s would certainly
make excellent build systems if they were ever supported though.

I hate to admit it, but I had gentoo on a Challenge S with a 5K,
but I'd be happy to test on:
Indigo2 10K
O2 5K
and maybe an Indy 4.4K though that one is up for grabs.

I'm interested in embedded linux. I've been working with mips + uclibc
on Mikrotik boards. I run gentoo on them using this technique:

http://opensource.dyc.edu/mips-devel

I put some stages up here

Thanks everybody for your responses.

A bit of background: MIPS has 3 ABIs: o32, n32, n64. o32 is the common
denominator, but is pretty inefficient. See [1]. As I suspected, all
the hardware people care about can use the n32 ABI, which is quite a
bit better.

To summarize the hardware collection
- 5 MIPS III/Loongson little-endian STMicroelectronics systems (Lemote, Gdium)
- 11 MIPS IV big-endian SGI systems
- 3 MIPS IV little-endian Cobalt systems
- 2 MIPS64 selectable-endian Broadcom systems

I've got a working n32 big-endian installation, and am preparing an
n32 little-endian installation at the moment. Once these are set up,
I'll start preparing some n32 stages.

I think first priority should be mips4 big-endian. From there, I don't
know whether I should build a mips4-le stage for cobalt systems, or a
mips3-le stage that would work for cobalt and Loongson. Do we know of
any plain MIPS III little-endian hardware?

Also, the MIPS port is going to be pretty unmaintainable until we can
kill off ~mips from ACCEPT_KEYWORDS. Currently, attempting to upgrade
almost anything causes something to break.

What do you guys think?

Thanks,
Matt

Hi Matt,

Sorry for my interference, but I want to write some random thoughts
that come and go, for while now. It's good that you asked about what
hardware we have these days. Btw, I have two SGI O2, a r5k and a r10k.
The r10k is useless for linux (unless something hanpened inside the last
~2 years that I served in the army and was away). The r5k is in good
condition but *extremely slow*. Once upon a time, when the mips stable
keyword wasn't dropped yet, I wanted to become a mips arch tester, but
found it extremely difficult to work with my r5k, cause it was very very
slow as I said before. I tried to find cheap and better mips hardware
but with no luck. Those days, Lemote just started to exist, and I
couldn't find any reseller in Europe. The SGI stopped direct support of
o2/origin hardware(unless I'm wrong), which makes it difficult for
someone to find spare parts in case something happens to a SGI machine
(unless you 're in US).
From the side of the gentoo linux developer/arch tester/(at least from
my side), we really need new, good and fast hardware in order to work
productively. For a big project, such the Gentoo Mips Project, we need
more people with good and probably also different hardware. But! For
example, it's very difficult to do any gentoo development(ebuild
writing/testing, arch testing, compiling stuff, even to build stages with
catalyst), with embedded hardware or with old SGI hardware.
So, my question is, what hardware can a gentoo dev get these days, in
order to work productively? And another question, a project such as the
gentoo MIPS project, should see where the future goes and not to live
in the past, supporting old hardware crap, so where does the MIPS future
go anyway? Will it go to embedded devices only? Will it also go to
desktop systems/production servers?

(I really believe that the gentoo MIPS project died the last years cause
people didn't have the right hardware to work)

I absolutely agree that the lack of usably fast hardware is the biggest problem.

While installing software on the O2 is slow enough as it is, having
some kind of quality-assurance from Gentoo/MIPS in the form of
ACCEPT_KEYWORDS="mips -~mips" would definitely make installing
software on the O2 less painful. Believe me, I've been there.
Compiling some package on a 300MHz R5000 takes hours, and then you
find out that it's clearly _never_ been tested when it breaks your
entire system so you've got to start the whole process over with a
different version.

I think the future of Linux/MIPS for regular users lies with
Lemote/GDium hardware. (We're probably going to not worry about things
like Octeon, for instance, since they're so expensive.) You'll notice
that many MIPS kernel developer work for companies using MIPS in
embedded environments though.

SGI systems are cheap and available though, so I think we should make
an effort to support them. The SGI Origin 300, with quad 600 MHz
R14ks, 4 MB L2 cache each, and 4 GB RAM is quite a fast system.
Unfortunately, the port has never been finished. O300s are quite cheap
(< 300 USD) and would make excellent Linux/MIPS systems, if only the
kernel port were completed.

I hope I've answered your questions. Please let me know.

Thanks,
Matt

Hello,

> I absolutely agree that the lack of usably fast hardware is the biggest problem.

While they're not the most common hardware out there, the Broadcom Sibyte MIPS boards make great build servers. Two or four cores in the 700-1000MHz range, with typically 1G of DRAM. I'm seeing what I can do about freeing up some additional boards for the Gentoo project. Details will probably have to wait until I get back from vacation (Hawaii).

Thanks,
Mark

I have some little-endian MIPS32 hardware which runs latest Gentoo.

I believe all the small MIPS32-based routers which run OpenWRT qualify.
Hoever I get the impression you want to focus on the "large" SGI
and 64bit Broadcom systems?

In my experience, lots of packages have problems with GCC-4.4 (removal
of the "h" asm constraint), and above all, the toolchain itself is
pretty problematic: Lots of linker errors with large libraries (e.g.
xulrunner, qt-webkit, gcj, ...)
