Yeah, I know!! This may be a dream, but I think it is to some degree
The thing with IRIX is that EVERYTHING has to be integrated and commercial
quality on first ship. What we really need to do in Linux is expose the
interfaces to things. If we give enough info to people it will generally
happen. I don't know what is involved to do this...maybe a skeleton driver
or something. It doesn't really matter whether it is optimised, or even bug
free, just as long as it gives those with the ability to write code like this
enough info to work with. As for applications and things to use this stuff,
thats up to the Linux community to do!

Yup, you're right, we are a systems company. I don't expect that Linux will
replace IRIX even in the distant future. IRIX isn't going to stand still, but
nor is Linux. One of the things I have noticed about Linux is that when
someone shows the way, things happen fairly quickly. Probably Linus's comment
about the symmetric multiprocessing was based on available resource, rather
than a lack of desire to do it. Maybe this is an opportunity for SGI to
provide some input into the Linux community...if we were to do some starter
work on this (on one of our boxes of course!!) I'm sure that others would
pretty soon catch on. The big thing with Linux is that we don't have to do all
the work....a bit of work on an initial framework and a push in the right
direction is often all that will be necessary. Let's take the ISDN port on
the Indy....if we somehow show people how to use this, I'm sure it won't be
long before someone outside of SGI gets it up and going! Same with audio.
Let's not think in terms of supplanting IRIX, let's look at growing the number
of boxes we ship. That's got ot be good for us!!
