Does anyone know how to recompile kernel ver 2.0.29 for SMP support?

Richard Hochron

you just have to enable the lines SMP and SMP_PROF  at the top of your
makefile in the src directory.

Much fun

Note, if you wish to install both a non SMP and SMP kernel with the same
version number and you use modules, it is best to also change the version
number (I changed mine to 2.0.29smp) by editing the SUBLEVEL variable.  This
way your modules for the SMP code will be installed in a different directory
than the modules for the non-SMP code.

Wrong solution!! This will break the "LinuxVersionCode" macro in the
kernel, used in a number of places (SCSI drivers for sure, I was
bitten by this). Instead, add a leading zero so the value is still
numeric. No, it will not suddenly become octal.

The macro is used to compile code matching your kernel, and I
believe it is used in some network and filesystem stuff to detect
2.1.30 and later kernels, as well as in the SCSI drivers.

I'm running 2.0.30 (uni) and 2.0.030 (smp) doing this, and it works
as expected. As you say, change the sublevel variable, but leave it
numeric.
