| 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. |
