I am interested in helping port to Indigo

[Fernando D. Mato Mira]

Hello,

What would one need to do to port what is running of SGI/Linux to 
Indigo R4400 150MHz Elan?

Regards,

One would need to write device drivers for:
- SCSI
- ethernet
- display or serial

I thought the indigo used either gio64 or gio32.  I might be wrong.

Have I missed anything?

     The original Indigo (R3000-based) used a different chip set from
the Indigo R4000, Indy, and Indigo2, which shared a common memory controller.
The latter machines use vary a bit in the details of their peripheral
chips, the parts are mostly either the same or different mainly in being
later revisions in some of the systems.  The Indigo2 added EISA bus support
(along with GIO).

     By "Indigo R4400", I assume you mean "Indigo2 R4400".  As far as
I know, we only supported the R4000 in the "Indigo R4000".  The 
kernel should be mostly compatible, aside from some details about
clocks, the addition of the EISA bus, and the absence of the video
port.  The big issue is the graphics.  Elan has downloaded microcode,
although you might make do with what is downloaded by the PROM.
Unfortunately, I cannot at present supply documentation for the
interface exported by that microcode (partly because I don't have
any ready to hand).

Nope. Indigo "1" R4400 indeed. 

And yes, it's GIO32.

  Perhaps you can supply us with a hinv output and picture of it, as I
have never heard of an Indigo with a R4400...

SGI did indeed build these with both 100 and 150 MHz processors.
It was called the IP20.

      I was familiar with the IP20.  I didn't realize that we had shipped
any 150 MHZ R4400 processors for the IP20.
