I added 4.2.6 and 4.3.0 mips-sources ebuilds to the Gentoo Repo a few days ago. Patchballs are on the mirrors. Previously, there were 4.1.7 and 4.2.0 ebuilds (SMP was added back in 4.1.x). I've not been holding anything back. Enable USE "ip30" to have the IP30-specific patches apply (typically, what I do is run 'USE="ip30" ebuild </path/to/ebuild> clean install', then copy the tree out of the '/image/' folder in $PORTDIR, and repeat as needed for IP27 and IP28 trees, as well. Omit the USE flag for IP22/IP32 systems. No IP35 yet).

It's running on my QEMU/MIPS builder
I will configure the kernel adding my ramrootfs
then I will try on IP30 hw, SMP, 2xR12K
testing everything

I was just messing around with Qemu. Isn't the clock speed for all MIPS targets locked to 100MHz? Not very fast emulation...

These two will probably give you the most headaches. Not all PCI works, and PCI-based USB won't work because of the PCI-to-PCI Bridge issue and the whole BRIDGE DMA problem still with Octane. I haven't tested MENET too much. The four Ethernet ports get detected, but not the six serial ports. Did not dig 100% into why.

Probably doesn't have a CI20 (and the CI40 is coming soon!). I'd love to get my hands on one of them, but I've got other areas that need my money at the moment. Also, the instruction set is a bit updated but is 32 bit only (MIPS32r2 vs MIPS IV) so there will be some issues there. There again, it'll use a lot less power then your i7 and probably is faster then any SGI box ever ended up being.

It is tempting, but as Armonox already pointed out, CI20 is mips32r2 only, and I need to build, at minimum, MIPS-III stages. I'll have to wait until Imgtec somes out with 64-bit class systems. Or someone helps hunt down the IP27 lockup bug, or IP35 gets whipped into better shape. So for now, my Octane, trusty as it is heavy, is my best build box.

I always keep forgetting to add one to the core patches. I took the one I have and stripped it down to the utter basics, so you'll still want to navigate through the menus and select stuff. I should have the bare minimum hardware options set, meaning stuff like SMP is off, so set things accordingly. And since I don't know how long it's been since you've seen a kernel >2.6.x (</snerk>), use the "nconfig" target instead of "menuconfig". It's a newer, better menu system for selecting kernel options. Just make sure your TERM is set right.

CI20 is only ~$65 on Imgtec's online store. It is tempting to get one, but the deal-killer for me is the lack of a small case. I don't really need permanent access to the circuits, so I'd like to seal machines like that up, without having to Dremel my own case or such out of acrylic. And then there's the 32-bit issue...
And electrical draw isn't that much of an issue. I'm in the Mid-Atlantic (not far from you, actually), and electric rates are, per my utility, ~$0.0807/kWh. The Octane consumes ~298-301W in its current configuration, so very rough math sets me out at ~$24-$31/mo at the present rates (after adding in the transmission charges per kWh and other little fees and the like), assuming I ran it 24/7. As long as I keep it tasked with work, it's worth the cost. That's why I can't afford to run the IP27 machine, because when tasked with work, the chances of the lockup bug happening increase dramatically. If it locks up when I'm not home, then it'll just idle there, sucking ~700W of power. If I can figure that bug out and fix it, then I can put that machine to work and justify the electrical costs.

sometimes means:
If I reset the machine, I can have two situations
1) the machine works perfectly, with an uptime of 20hours without issuing any error
2) the machine continuously issues the above error and it's forced to reset
it happens randomly
I have removed the GFX, the Kb&mouse
I have 1.5Gbyte of ram installed, without an hard drive
the same happens if I plug a V6 |

You'll want to compile debugging symbols into your kernel. Raw addresses aren't very useful, because I don't have your System.map file or anything.
The other thing I can think of....are you using transparent hugepage support by chance? If so, disable that and try again. Known issue with that feature on IP30. Seems the R14000 CPUs make it even worse. This option is in the Kernel settings. Also disable hugetlbfs support under File Systems (might be dependent on hugepages, so if you disable (or have disabled) hugepages, then I don't think hugetlbfs support will be visible).
Also, when you get an IBE, make sure to fully power the machine down and unplug the power cord for ~30 seconds. I had this issue with the DBEs in which the caches weren't being cleared correctly or the hardware not reinitialized correctly with a plain reboot or quick power cycle.

I have removed in order to reduce the file size, currently we are 11Mbyte of Kernel +ramrootfs

the above machine is 2xR12K
I am using two machines, mine is 2xR12K, my friend is 2xR14
both of them have the same issues

have you seen my front plane hack ? it's useful for this purpose, I can remotely force a power down + cable unplug
there is a rele of 20A between the 220V plug and the IP30-PSU
the whole looks similar to the L2 controller used in Terzo!
btw, can't we have a proper piece of assembly code to invalidate the cache ?
do I have to post here my .config ? |

Any news?
I've seen a linux (t2sde) port for octane here
It will be awsome if we can see gentoo arrives on the octane

was the last stage3 available for MIPS4/be made in 2014?
anyone has a more recent autobuild stage3? |

you have been asking the same question for eleven years ...
well, in 2008 we *had* gento working on IP (I still have my stage4 in my backups)
as we *had* gentoo in 2014
Currently, there two problems: - lack of testing - and - lack of updated stage3-mips4
There is a kernel 4.*, there is no kernel 5.* (is there?).
I also know there are a few issues with ssh and related. I haven't checked yet by myself, but I will! |
