(usagi-users 03571) USAGI on a SUSE Linux PC compile errors

[Tim McFadden <tim@xxxxxxxxxx>]

Dear USAGI,

I am trying to load USAGI on a Linux PC and get compile errors in the 
kernel code and would appreciate help with finding the correct options 
to use.

I am using SUSE 10.1. The current Linux kernel is “2.6.13-15-default”

After the prepare and mrproper, in ./kernel/linux26 I do:

“make”

The supplied code from “USAGI STABLE Release 6” gets assembly errors in

./kernel/linux26/arch/<whatever_architecture>/kernel/process.c.

E.g., /kernel/linux26/arch/i386/kernel/process.c.

I am using “gcc 4.0.2 20050901 (prerelease)”, supplied on the SUSE CD. I 
can't find any relevant bug reports on the SUSE site.

The error messages are:

“Error: suffix or operands invalid for mov”

From the assembly listing, they object to any:

“movl %gs....” or “movl %fs....”

E.g., the following code gets errors:

-------------------------------
#APP
movl %fs,504(%ebp)
movl %gs,508(%ebp)
#NO_APP

I've tried the “make menuconfig” processor options that seem to make 
sense, but still get the errors. I've compiled process.c separately from 
a small script and plugged in all the “gcc” options I could find for 
“-march”, etc., which also fail.

No options I can find can deal with code like:

“movl %gs....” or “movl %fs....”

The version of process.c supplied with the SUSE CD kernel code uses:

“mov %fs...”

and is quite different code, anyway.

I haven't been able to download the relevant Intel processor manuals 
from their site, to help shed light on the problem.

Thank you for any help.

Tx,
Tim McFadden
