HI
I have just spent hours trying to figure this out, through google
but no luck. I have a single pentium 4 w/ hyperthreading and am
running kernel 2.6.13. I built my own kernel and enabled HT and
the system seems to recognize two processors.
Here is /proc/cpuinfo:
/----------------------\
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Pentium(R) 4 CPU 3.00GHz
stepping : 9
cpu MHz : 3000.571
cache size : 512 KB
physical id : 0
siblings : 2
core id : 0
cpu cores : 1
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes

\------------------------/
But I can't find any sign that HT is working properly. Here is my
/proc/interrupts file showing only one processor doing anything:
/------------------------\

23: 2 0 IO-APIC-level ehci_hcd:usb5
NMI: 0 0

\-------------------------------/
I believe I have all the necessary kernel options enabled
but I may be doing something wrong. I saw some posts
about including 'acpismp=force' to the boot parameters
but I think these were for old 2.4 kernels.
Thanks for your help,
Brandon
