kernel 2.4.25-pre8 fails to build for sparc32

[Nicolas Boullis]

Hi,

First of all, sorry if I'm doing something wrong with this report, I'm 
still quite a newbie on this list...

I just tried to build a sparc32 kernel for my Ultra5. (I know this is 
sparc64 hardware, but I need to test some things with a sparc32 kernel, 
and I think it's supposed to work fine...) Unfortunately, the build 
fails with the following message:

Can anyone help me sove this failure?


TIA,

Nicolas

I think you're confused.  You probably mean you want to use a 32-bit
userland, which you can do just fine with a sparc64 kernel.  The
sparc32 kernel does not support ultrasparc CPUs nor any of the
associated hardware in ultras.  Please do not bother trying to make it
work.  Use ARCH=sparc64 and all will be well.

Well, I dont' think I am that confused. I'm currently using a 64-bit 
kernel, with 32-bit applications, and everything works fine.

But I'd like to check if XFS is as broken in 32-bit as in 64-bit (the
64-bit kernel freezes when a XFS restore is attemted), and to try a
driver module in 32-bit mode. As far as I know, both require a 64-bit 
kernel...

Well, I thought that some distribution were using a 32-bit kernel for 
installation, even on sparc64... Was I wrong?

Yes.  See arch/sparc/kernel/head.S:no_sun4u_here.  Or about a hundred
other places in the sparc32 code where ultras clearly couldn't
possibly work.
