Tag kernel26-2.6.12-alx-r9
1 | To set up SMP |
2 | |
3 | Configure the kernel and answer Y to CONFIG_SMP. |
4 | |
5 | If you are using LILO, it is handy to have both SMP and non-SMP |
6 | kernel images on hand. Edit /etc/lilo.conf to create an entry |
7 | for another kernel image called "linux-smp" or something. |
8 | |
9 | The next time you compile the kernel, when running a SMP kernel, |
10 | edit linux/Makefile and change "MAKE=make" to "MAKE=make -jN" |
11 | (where N = number of CPU + 1, or if you have tons of memory/swap |
12 | you can just use "-j" without a number). Feel free to experiment |
13 | with this one. |
14 | |
15 | Of course you should time how long each build takes :-) |
16 | Example: |
17 | make config |
18 | time -v sh -c 'make clean install modules modules_install' |
19 | |
20 | If you are using some Compaq MP compliant machines you will need to set |
21 | the operating system in the BIOS settings to "Unixware" - don't ask me |
22 | why Compaqs don't work otherwise. |
