]i keep reading conflicting information that 'openbsd now supports x on MIPS' as well as 'bsd is text only on octanes'
here i am, i am a gentoo/mips guy, and i am used to toy with gentoo on Octane2 (IP30)
linux is pretty dead on IP30, the only working kernel is 2.6.17, everything else is not working, or incomplete
e.g. the SMP is dead, the XIO-PCI is dead, too
the 2.6.17 has SMP, but with bit kernel lock, that means if you have 2 CPU then it looks like having one CPU plus an half instead of two
also there are a lot of issues about handling more than 1.5G byte of ram

I wanted to see if using only the unaccelerated framebuffer would give me x11 on a defective card that causes segfaults under irix
-
V6 graphics cards
are not able to run X11, details are missing, so more hacking activity is required: you can ONLY use it as text console
-
Impact/SR graphics cards
are able to run X11, so you can use them for both text console and X11
personally i have put both the graphics cards inside my IP30, but i am not using none of them: i simply prefer to use the machine remotely (too noise machine, and everything works better through an ssh tunnel)
i am experimenting the pci, which is not exactly intel-pci-specification compliant, btw i can plug an usb-disc achieving a throughput of 20Mbyte/sec

I used to run Gentoo Linux on an Octane at college 2GB RAM
which kernel release ? 2.6.19 is not so pretty here, and i am considering it as "unstable"
also, 2Gbyte of ram is not possible if you have a XIO-PCI, there are a lot of issues about XBOW

but framebuffer X is really horrible
not so horrible, but it's usable ONLY if you have a light
windows manager
in my case i used and hacked
x11-wm/enlightenment
with a very reduces set of features
actually i am using the machine remotely, through ssh, and serial (kgdb, kernel debugger, MIPS-STUB in kernel space, attached to the serial port)
here is the screenshot from the serial console, it was a bit of time ago, Fri Aug 9, 2013

as you can see the
PCI_USB
is working, i have attached an
USB_DISK
. Performances are not so good, i achieved a maximum of 20Mbyte/sec because the XIO24 has a bit of issues opening a windows to the PCI sub module, also … a lot of issues choosing the right PCI_USB chip (OHCI & EHCI) because SGI is not compliant with the
PCI standard
.
graphics are are not not installed because the kernel is under debug activity
