hi,
sgi octane/octane2 could be equipped with a PCI cage, a special unit that makes the machine able to accept PCI boards.
V6 gfx is good enought to be used as text console, but it is not supported as Xfb device: so no X11 on V6.

The idea is to use a matrox m1 or matrox m2, or a voodoo2 pci board plugged in the pci cage.
Also it should be nice to add an USB/firewire/sata support for the octane.

isn't it ?

so, i'm opening this thread to report the hardware that is known to be well running on octane-pci-cage.

Feel free to post about it, or to post about the not working hardware.

about the pci-cage, in kernel sources you can read


Code:

sys-kernel/mips-sources-2.6.17.10
Things to keep in mind when building a kernel for an SGI Octane:
- Impact (MGRAS) console and X driver work, please report any bugs.
- VPro (Odyssey) console works, but no X driver exists yet.
- PCI Card Cages should work for many devices, except certain types like
PCI-to-PCI bridges (USB hubs, USB flash card readers for example).
- Do not use OHCI-based USB cards in Octane. They're broke on this machine.
Patches are welcome to fix the issue.
- Equally, UHCI Cards are showing issues in this release, but should still
function somewhat. This issue manifests itself when using pl2303 USB->Serial
adapters.
- Other XIO-based devices like MENET and various Impact addons remain
untested and are not guaranteed to work. This applies to various
digital video conversion boards as well.



i've putted a matrox m2 inside this PCI-XIO bridge, dmesg is reporting that matroxfb: probe of 0001:01:01.0 has failed with an error.


Code:

PCI: Failed to allocate mem resource #1:800000@1d800000 for 0001:01:01.0
pci_hotplug: PCI Hot Plug PCI Core version: 0.5
fakephp: Fake PCI Hot Plug Controller Driver

I found it about 3 weeks ago on google for $58 - WAAAAYYY less than any of the people on eBay have had it for. If their is good support this would open up things like USB / Firewire support which would totally kick ass.

People have done USB with the pci cardcage. Unless I'm mistaken, there were/are problems with USB storage. My solution for the USB storage problem is to plug usb devices into my laptop. I can then access them remotely through the gigabit ethernet card in the pci adapter.

$58.00 (US?) is a good deal for a pci cardcage. I had to get a whole 'nother Octane to get mine. It was a good deal, too, but I think I would have gone the $58.00 dollar route had I known about it.

hi,
modern computers can use SAN and NAS solutions about storage
- SAN (Storage Area Network)
- NAS (Network Attached Storage)


to do NFS, i'm using my embedded walnut-ppc405 (it costs < $100) , equipped with a native ATA controller, and with 2 PCI slot where i plugged a PCI-2-sata (gentoo is running on this board, this means we could have a good support for all the pci devices supported on the linux kernel tree)


So i can add sata disk to my octane2 using NFS, but we are speaking about an home-made tini-NAS that is working with 10/100Mbit ehernet connection, all based on gentoo

this is not the best solution i aim for: i really want to use the pci cardcage with a sata and usb card inside :)

in the future, with a good pci cardcage we will do.

(and we also add a matrox or vodoo, making us abled to use X11 on ocatne2)

i got great success with the NEC PCI USB
i had to hack the kernel 2.6.17.14 a bit
(all kernels > .17 are simply not working)
but now i have an USB hard drive pretty working :D
