Dear Gentoo Users and Dev, |
2 |
|
3 |
I've just installed on my desktop the last gentoo-sources package ( in portage |
4 |
(2.6.16-r7). It seems that the hyperthreading is unvailable since when I do : |
5 |
'cat /proc/cpuinfo', I can just see a single computer. |
6 |
|
7 |
That is really strange since I was using the previous package |
8 |
(gentoo-sources-2.6.16-r6) with hyperthreading feature enabled. |
9 |
|
10 |
To build my kernel, I use genkernel (with --menuconfig option). I keep the |
11 |
same configuration as the one for gentoo-sources-2.6.16-r6, that I loaded. |
12 |
|
13 |
In my '.config' file, I have the following options, that as I know should make |
14 |
hyperthreading available. : |
15 |
CONFIG_MPENTIUM4=y |
16 |
and |
17 |
CONFIG_SMP=y |
18 |
CONFIG_NR_CPUS=2 |
19 |
CONFIG_SCHED_SMT=y |
20 |
|
21 |
My CPU is a single Pentium 4 3.2GHz with HT. Hereunder is the result |
22 |
of 'cat /proc/cpuinfo' with the previous kernel: |
