O/P:

*ht_enable    0  INFO  :  Begin: HyperThreading Enabled
ht_enable    0  INFO  :  The kernel boot paramter 'noht' is not set.
ht_enable    1  FAIL  :  HT feature is not included in this Linux Kernel.
ht_enable    0  INFO  :  End: HyperThreading Enabled *



but noht is for disabling hyperthreading.

Function *is_ht_kernel* (file:
testcases/kernel/sched/hyperthreading/ht_affinity/HTutils.c) checks for
string *cpu_package* in /proc/cpuinfo  .

 but *cpu_package* string  information  does not exist in  /proc/cpuinfo for
2.6.29 kernel


 Regards,

Rohit
