I just upgraded my Gentoo server from an old Celeron 1Ghz to a Pentium4 |
| 2 |
3Ghz (hyperthreaded). |
| 3 |
|
| 4 |
In /etc/make.conf I have: |
| 5 |
|
| 6 |
CHOST="i686-pc-linux-gnu" |
| 7 |
CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer -mfpmath=sse |
| 8 |
-mmmx -msse" |
| 9 |
MAKEOPTS="-j3" |
| 10 |
|
| 11 |
I compiled the new kernel and added some SMP stuff I saw: |
| 12 |
|
| 13 |
daevid ~ # uname -a |
| 14 |
Linux daevid.com 2.6.19-gentoo-r5 #2 SMP PREEMPT Sat May 26 13:50:25 PDT |
| 15 |
2007 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz GenuineIntel GNU/Linux |
| 16 |
|
| 17 |
But when I'm in KDE, the little load applet doesn't show two CPUs |
| 18 |
(should it?). |
| 19 |
|
| 20 |
So how can I tell that it's being used, and what "tool" will show me |
| 21 |
both CPUs and their loads n stuff (like WinXP does in taskmgr -- this |
| 22 |
used to be an XP box BTW. I "upgraded" it ;-) |
