make modules and SMP?

make modules and SMP?

When you're building on a SMP host, by default rhconfig.h includes a
file called "/boot/kernel.h"  

It will have following variables set:
-- ---- ---- ---- ---- ---- -----
#ifndef __BOOT_KERNEL_HUGEMEM
#define __BOOT_KERNEL_HUGEMEM 0
#endif

#ifndef __BOOT_KERNEL_SMP
#define __BOOT_KERNEL_SMP 1
#endif

#ifndef __BOOT_KERNEL_UP
#define __BOOT_KERNEL_UP 0
#endif
-- ---- ---- ---- ---- ---- ---- ---

So, either you need to boot with a UP kernel to do a UP build, or change
/boot/kernel.h file to the following settings:

-- ---- ---- ---- ------
#ifndef __BOOT_KERNEL_HUGEMEM
#define __BOOT_KERNEL_HUGEMEM 0
#endif

#ifndef __BOOT_KERNEL_SMP
#define __BOOT_KERNEL_SMP 0
#endif

#ifndef __BOOT_KERNEL_UP
#define __BOOT_KERNEL_UP 1
#endif
-- ---- ---- ---- --

Hope this helps,
Jayaram.

Subject: make modules and SMP?

I'm trying to recompile the tg3 module on 2.4.21-32.0.1.EL using a patch
from Hewlett Packard.  It just patches the tg3 module in Update 5 to be
the version from Update 6.  This will allow me to load Update 5 on their
newer workstations (XW4300, for example).

I've run the following commands after patching the tg3 source:
make clean
make mrproper
cp configs/kernel-2 (See http://nel-2.ora-code.com).4.21-i686.config .config
make oldconfig
make dep
make modules

I'm running this in a SMP machine, but I used the UP config.  When I run
"strings tg3.o", it build the right version (3.27RH), but it mentions
the SMP kernel "kernel_version=2.4.21-32.0.1.ELsmp".

What am I missing to build the UP tg3.o on an SMP host?

Thanks.

/Brian/
