hi,
i have a bit collection of issue here trying to compile 2.6.2* ...
i had success with 2.6.17 in 2006.1, and it was a lot of time ago, i mean i know whenever i plan to use an older config on a newer kernel, i always have to check the config to make sure it didn't flip something off. Things changed dramatically from .17 to .2*, and relying on oldconfig alone isn't recommended. So, after having failure trying to use the 2.6.17/.config i erased and rewind running through menuconfig and just check the categories for a fresh new .config

Unfortunately still the new kernel does not boot: nested exceptions sometimes point at ARCS bugs. ... somebody is talking about "out-of-date PROM" ... and what i get when i try to boot 2.6.22.6 is: "PROM WRITE ERROR ON CACHELINE 0x1fcba700 at PC=0x203f302c"

my prom monitor sgi version 6.5 rev 4.17 IP 30 jan 20, 2004 - 64 bit


anybody has success with 2.6.2* ? if so which release ? could i see the config ?



i'am using gcc 4.1.2, kgcc 4.1.2, binutils 2.17
my machine is a 2xR12 IP30 system

Quote:
mips-sources-2.6.20.18 & mips-sources-2.6.22.6 marked as stable
Support has been marked as needing testing in this
ebuild revision. This usually means that any patches to support
have been forward ported and maybe even compile-tested,
but not yet booted on real hardware, possibly due to a lack of access
to such hardware.
If you happen to boot this kernel and have no
problems at all, then please inform the maintainer. Otherwise, if
experience a bug, an oops/panic, or some other oddity, then please
file a bug at bugs.gentoo.org, and assign it to the mips team.

here it is the status of kernel
2.6.17.14.ip30: hardly tested and solid rock working (used to build the 2008 stage3, and his world: 10days uptime)
2.6.20.18.ip30: it boots but is is reporting a lot of bad debugging info
2.6.22.6.ip30: it doesn't boot, PROM WRITE ERROR ON CACHELINE 0x1fcba700 at PC=0x203f302c
2.6.23.*.ip30: it is marked as ~mips, i have to give it a try

As I recall... Kumba has been rather busy trying to straighten out IP30 support. Some upstream changes broke the IP30 patchset, and thus he's been busy working with Skylark in the #mipslinux channel, sorting out the mess.

There's a newer ebuild too... 2.6.24-something for mips-sources. That might be worth a shot too.

Well, the Octane is not exactly a common peice of equipment, and they weigh a ton. And, they are a bit troublesome to use Linux on. Which, is why I doing so =).

Sadly, other projects (and work) have kept me away from the Octanes for quite some time..

I gave my octane IP30 to UC Berkeley, can anyone assist them with a netboot install, since IRIX isn't allowed on the network. (plus I hate Nekroware.)

I was able to get it working about a year ago, but opted for IRIX because it was a fun "toy" but since donating it, they need to have Linux on it for security.

It's going to be used for MIPS programming.

Is there a step by step easy guide that is known to work for getting Gentoo netbooted on the IP30? I followed one a while back, but it's been so long since I did it, and not sure where I found it in the first place.

Thanks again!

the main problem is which kernel to run on it!

I mean emerge --search mips-sources doesn't mean "this kernel will be stable on sgi-mips machine"
(example, the 2.6.22 it not working on my sgi-octane2-R12K, but it is working on my routerboard-mipsR4K board)

I am not so updated about new stable octane/kernel news, but here I'm running the 2.6.17 and I can personally assure that it is stable ... the .24 hasn't been tested on my octanes, so actually I can think only about the .17 that unfortunately has been removed from the current portage, so ... (in case i can provide you a tgz of the kernel 2.6.17 patched sources for octane2-R10K/R10K+)



umm, why netboot ? can't you get an hard drive and install gentoo userland on it ? it is a better idea with fewer issues

any news about gentoo mips-sources or tested kernel (>= 2.6.17) on ip30 ?

any (updated) web like http://home.tal.org/~milang around ?

Negative. For all intents and purposes, Octane/IP30 is effectively dead on Gentoo, and Linux in general. The only OS that I know of that currently supports Octane, outside of IRIX, is OpenBSD. I haven't had a lot of time to attempt to figure out what to fix, and I've lost the ability to use the "Early Printk" hack that Stanislaw created once, that hijacks the kernel's core printk call to scribble characters out to the graphics board directly. The introduction of the buffered printk stuff in 3.6.x killed that capability. Stanislaw himself has effectively dropped off of the planet, as far as I know, so he won't be updating Octane anytime soon.

That said, I do maintain an experimental patch in the sys-kernel/mips-sources ebuilds that you can apply via the 'ip30' USE flag to play with the code. It applies on top of the old IOC3 metadriver patch. It contains the core of the Octane code, plus the ImpactSR and Odyssey drivers, as well as various hacks that were my feeble attempt to get the kernel to boot again. Feel free to play with it and learn. Reference the OpenBSD code below for inspiration (but mind the licenses!):
http://www.openbsd.org/cgi-bin/cvsweb/src/sys/arch/sgi/sgi/ip30_machdep.c

The long-standing issue has largely been getting the IRQ handling done right. Octane's HEART chip, the system ASIC, handles the interrupts, but it's a bit of weird thing. It has one 64bit interrupt status register (ISR) and one 64bit interrupt mask register (IMR) per CPU. HEART defines a maximum of 4 CPU's possible, but SGI only ever produced a two-CPU design (I wonder if a quad board exists in some forgotten prototyping lab...). The trick is, there are a hardwired-set of around five interrupt priority levels built into the status/mask registers, and you have to properly read these two registers to know how to route interrupt requests properly.

There was also something about how you assigned IRQ numbers, too, that always confused me. Only thing I have to go by are some IRIX header files I managed to find, Stan's original (booting) code, and what the OpenBSD developers have figured out. I believe the original Octane kernel code in Linux hardcoded specific IRQ numbers for things like the CPU SMP mailboxes, specific devices, etc. But then it had a bit of code to dynamically generate/allocate IRQ numbers for everything else, and I never understood what that was doing exactly (no comments in the code).

AND THEN, you have the IOC3 to deal with. It's the PCI device that implements a bare skeleton of the PCI spec, but wants to be its own bus, and off of it hangs SCSI, RTC, Audio, Networking, Keyboard, and Mouse. So when it acts up, everything breaks. I got a feeling, though, that if the main IRQ handling can be worked out, IOC3 might just work, since it's been maintained in the main kernel w/ Origin 200/IP27. Big guess on that.

So, if anyone wants to take a crack at it, those are your outstanding issues. And probably a lot of other ones that have cropped up in recent years. I'll try to get an updated mips-sources out in the next few weeks for either 3.12, 3.13, or whatever is current then, that'll include a compilable (but likely not bootable) Octane patch.

Okay, some updates -- Octane boots again. Celebrate!

Thanks go out to Johannes Dickgreber (Tanzy) for several patches a few years ago that got me started on the right path.

Caveats:
  • Uniprocessor Only -- problems with getting timer/system ticks to broadcast correctly between two CPUs is still a mystery to me. It's probably a real simple fix, so when I release the patch in an upcoming mips-sources update, anyone who understands SMP, please feel free to take a crack at it.

  • No serial console support. The SGI Altix IOC3 driver appears to work -- it gets an IRQ assigned, tries to change baud rates, etc. But I get no output on a serial console. I have not investigated yet -- it might be a trivial fix. The older way of kludging the 8250 driver to work is still an option, and I might be able to get that to work instead. We'll see.

  • PCI Card cage devices are detected, but I have been unsuccessful in getting to work just yet. It is very likely they are just not compatible with big-endian MIPS. Namely, a StarTech serial card flat out panicks the kernel due to supporting only little-endian. USB has always been problematic, but I'll try that again soon at some point. And my third card, an SGI Gigabit adapter (Alteon/Tigon chipset) doesn't seem to want to come online correctly -- complains about missing firmware. So, this needs more investigation.

  • RAD1 Audio is detected, but non-functional, based on my last test. I tried playing a WAV file using a really old 'aplay', but all I got were some static 'pops' out of the headphones. It is possible this is due to a an extremely new kernel (3.14.5) running against an old (~2009) userland. I'll attempt this again once I find a way to update the userland (which will take a while).

  • PCI Code is still a bit funny. I have a hack in pci-ip30.c right now that sets one of the Bridge resource types to IORESOURCE_BUS, which allows the system to detect both PCI bridges (if you have the card cage). This is obviously wrong, however. But to really fix it, it needs changes to the core MIPS PCI code to handle an additional IORESOURCE_* type.

  • R14000 CPU ONLY: You cannot use CONFIG_TRANSPARENT_HUGEPAGE in the kernel config. It must expose some kind of R14000-specific errata that's either unknown or undocumented. This triggers an Instruction Bus Error that can only be cleared by a full power down of the machine, 30s wait, then starting it up again. Oddly enough, the issue does NOT appear if CONFIG_SMP is also selected. Something to dig into more at a later date. R12000 and R10000 should be fine, though.

What does work:
  • SCSI works great, and hdparm even reports ~18.5MB/sec throughput, which is good.

  • Odyssey Console + Early Printk -- Now you can see early boot messages before it switches over to the primary framebuffer. Odyssey is still a little sluggish in drawing text to the screen, however. The driver probably needs more work by anyone who can figure this graphics card out some more.

  • Impact Console + Early Printk -- like Odyssey above, you can see early boot messages before the primary console takes over. Unlike Odyssey, though, Impact is much faster in drawing text to the screen. I have NOT tested X11, however.

  • RTC -- I was able to adapt the DS1685 RTC driver that I wrote for the O2 to work for the Octane, as they both use the same DS1687-5 RTC chip from Dallas/Maxim. Given the age of your average Octane, though, some of these RTCs may be near end of life. The good news is that DS17x87-5 chips work fine in both machines (my O2 has a DS17287-5 and the Octane has a DS17887-5). Those needing to replace their RTCs can find them for sale on the internet from several electronic component websites.

  • Keyboard and Mouse -- Keyboard most definitely works and I assume the mouse also works. I don't have gpm installed, but I can jiggle a mouse and then `cat /proc/interrupts` and note that the 'ioc3-io' interrupt count goes up a fair bit. So the driver is at least processing mouse events, but until I get the userland updated and/or X11 re-installed, I won't know for exactness. But until then, assume the mouse DOES work.

  • Ethernet works. I have not done benchmarks yet to see if it's slow or anything, but transferring large files to my amd64 box did not take long at all.

Untested:
  • PCI Shoehorn -- I have an Origin 200/2000 PCI Shoehorn, but they don't fit in an Octane. I am uncertain how the IRQ assignment will be should one get plugged in. Shoehorns were made for Octane, however (there is one on eBay right now). This is something that needs testing to see what changes, if any, are needed to the IRQ assignment code.

  • MENET boards -- Also untested. They're all IOC3-based, so since the main IOC3 driver appears to work fine, these might also work. But since the IOC3 chips will sit behind a BRIDGE chip, the IRQ assignment, like w/ the Shoehorn above, is questionable.

  • All other XIO boards -- Untested. Feedback will be appreciated when I have the patch released.

Wow...I didn't think we'd see that come back. I might have to setup a new netboot image at home (IRIX on HDD, never got Gentoo to boot locally when I was running it years ago). How long do you think emerging the userland would take? I'm thinking in weeks at this point (I remember how slow it was back then with dual 300MHz procs and 4GB RAM....my personal Octane isn't that powerful)

Well, I have a 600MHz R14000 and 1.7GB of RAM in mine. So combining the use of a tmpfs for PORTAGE_TMPDIR will help to speed things up a bit. I am going to attempt to update my ~5-year old userland, which is already proving to be a challenge. I only had Python-2.5 on it, so I had to juggle some things to get Python 2.6 and Portage-2.2 on it. Managed to kill OpenSSH (segfaults), so now on dropbear for the time being.

Plan is to get up to Python-2.7, re-merge Portage again, then binutils, gcc, glibc, repeat again to fully update the toolchain, then re-do Portage/Python/Perl again, then start upgrading the rest of the system. Once it starts going, it actually moves along at a good clip. SMP would help obviously, but I am stumped by the IPI/Timer handling right now. I really need to focus more on handling IORESOURCE_BUS in the MIPS PCI code, maybe tackle serial support, and start to roll patches to post to linux-mips and see if others can help fix problems. Then get mips-sources updated. I might post/announce a beta patch on the mailing list in a few days or next week.

Figure I'd update:
  • Fixed IORESOURCE_BUS issue.
  • Serial works by driving the UART directly w/ the 8250 core. Max baud is 38.4kbps. To go any faster, I or someone else will have to play around with the Altix IOC3 serial driver, which does all of the fancy DMA stuff, to get it to work.
  • Cannot use CONFIG_TRANSPARENT_HUGEPAGE if using an R14000 CPU. Triggers some kind of Instruction Bus Error. I still have to dig into this, but either skip this kernel config option if I don't figure it out, or enable CONFIG_SMP, regardless if you have an SMP module or not (but if you do, disable CPU1 in the PROM first!).
  • Audio is still dead. It compiles and detects the card, but just emits static clicking. I haven't tried it again so far.


That's the hardware issues. Software, I got my userland mostly updated. However, there's a regression in gcc-4.8 that, so far, affects R10000-based MIPS platforms. I've verified it on the Octane, and on an Onyx2. Also in o32 and at least n32. Symptom is, compiling a program w/ g++ and linking to libpthreads causes a hang in the futex syscall. I discovered this one via Python-3.3.5's configure script. Another symptom is if building glibc, at the very end of the install phase, it tries to run a static copy of ln, 'sln', which also hangs in a futex syscall. Problem appears to be inside gcc somewhere, as the ordering of ASM statements changed and this appears to make the code unhappy.

Currently doing a git bisect of gcc and going to try and hunt down the problem commit. Have not verified on my O2, though, which has an RM7000 CPU.

See gcc PR61538 or Gentoo Bug #516548 for the gory details.

I thought GCC dropped o32?

They can't -- that's the pure-32bit userland. n32 and n64 both require a 64-bit toolchain.

I am currently building new install stages for big-endian MIPS, however, the Octane is only able to compile code so fast, so it's taking a while. Not sure yet about netboot images. I'll probably need to bootstrap a new big-endian uclibc stage-set for those, so I may just skip straight to attempting a new LiveCD, console-only. X is a whole-different can of worms.

Oh, I understand that. Shame too, that we'll probably never have X running nicely outside of IRIX (not that I have an issue with IRIX, so much less politics and such. Nobody arguing about replacing the init system, or Wayland, etc; just some things that are stuck in 2003).

Yeah, but that's not going to remain around for long. gcc dropped IRIX support in 4.7, so eventually, software simply won't compile anymore. It'll be hard to maintain software like Nekoware w/o a modern gcc. That will take a few years, of course, but it's surprising that gcc dropped IRIX support before it dropped NetWare support.

X should work w/ the Octane's as long as you have an Impact board. I don't think anyone has actually compiled the X impact driver in a very long time, though. That'll also be on my todo list, but not for a *long* time.

See this thread now for Octane information.
