ARM26 [NEW ARCHITECTURE]

ARM26 [NEW ARCHITECTURE]

[Ian Molton]

Hi.

I want to submit the ARM26 architecture. its still broken, but its
getting there. now a couple more people want to hack on it, so I'd
appreciate it if you could put the non-invasive parts into the kernel
tree for me.

I have two patches - one to add arch/arm26 and another to add the
corresponding incluse/asm-arm26

will you accept them?

I guess its no crazier than the MacII port. What does Russell think
about it however and also is this 2.4 or 2.5 targetted ?

I know its a bit insane, but there appears (at long last!) to be a small
community picking up ;-)

Russell is fine with it, and in fact, you can see he has begun accepting
patches from me to remove arm26 from 2.5.

it is 2.5 targetted currently 2.5.30, but the arch/ and asm/ stuff is
independant as far as the rest of the tree is concerned, so it may as
well go in as 'current' and then I can submit smaller patches to 'catch
up' with the rest.

it actually compiles on 2.5.30 (at least, some of it does ;-) and runs,
excpet so far, mm stuff fails and user-land falls over HARD ver early.

where do I send my patches? ;-)

I'll roll the include/asm and arch/arm26 bits into -ac happily, if only so
they are seen for criticism. (Read hch filling your mailbox 8))

I'm fine with it; I'd rather someone else (who has more interest
in the machines) picked it up.

The basic idea is to rip out the arm26 code from arch/arm and
include/asm-arm, thereby allowing include/asm-arm/proc-armv to
be collapsed into include/asm-arm, removing some clutter.

Separating it out should also allow arm26 to shrink down to
something smaller, which is fairly critical for these machines.

Yep.

speaking of which - let me know when you want the next round of patches
to remove the ARM26 stuff from arch/arm please ;-)

Yep. the [compiled size of the] kernel has already begun to decrease,
and its looking quite promising (If I ever get the time to finish it!)

I just want to get it 'out there' so the couple of other folks
interested can start hacking on it too.

I have an ide driver too, if anyone wants to submit it for the
mainstream kernel. It drives SIMTEC IDE cards, found in Acorn machines,
and is, of course, non-invasive to the tree. Its for 2.4. I'd imagine
Russell would be happy to let someone else take it off his hands?

Wait until we're gonna submit the TekExpress port for 2.4.22... ;-)

That's hilarious and ironic.  It was because of the hefty price of
things like the TekXpress XP15 that I first got interested in Linux
(Slackware 1.0.2) as a relatively cheap and effective X-terminal for our
clients running on a DECstation 5000 (MIPS R3000).

The name TekExpress or TekXpress could be confusing since some had 68020
or 68030 CPUs and some had the MIPS R3000 if I remember correctly. 
Googling shows quite a few variants of name/CPU type.

I was talking about the m68k variants.

And a port of qemu so it can run x86 binaries too ?
