To set up SMP
|
||
|
|
|
||
|
|
Configure the kernel and answer Y to CONFIG_SMP.
|
||
|
|
|
||
|
|
If you are using LILO, it is handy to have both SMP and non-SMP
|
||
|
|
kernel images on hand. Edit /etc/lilo.conf to create an entry
|
||
|
|
for another kernel image called "linux-smp" or something.
|
||
|
|
|
||
|
|
The next time you compile the kernel, when running a SMP kernel,
|
||
|
|
edit linux/Makefile and change "MAKE=make" to "MAKE=make -jN"
|
||
|
|
(where N = number of CPU + 1, or if you have tons of memory/swap
|
||
|
|
you can just use "-j" without a number). Feel free to experiment
|
||
|
|
with this one.
|
||
|
|
|
||
|
|
Of course you should time how long each build takes :-)
|
||
|
|
Example:
|
||
|
|
make config
|
||
|
|
time -v sh -c 'make clean install modules modules_install'
|
||
|
|
|
||
|
|
If you are using some Compaq MP compliant machines you will need to set
|
||
|
|
the operating system in the BIOS settings to "Unixware" - don't ask me
|
||
|
|
why Compaqs don't work otherwise.
