Hyperthreading? AMD64 CPUs don't need nor should they be configured with |
| 13 |
that. If you have an Intel, with it's deeper pipeline, some of /them/ use |
| 14 |
hyperthreading. |
| 15 |
|
| 16 |
Assuming it IS an Intel... |
| 17 |

You probably enabled SMP (symmetric multi-processing support) but not SMT |
| 19 |
(Symmetric multi-threading --- Hyperthreading) scheduler support. The |
| 20 |
latter is a suboption of the former, only available if SMP is enabled. |
| 21 |
|
| 22 |
Those options are under processor type and features under make menuconfig, |
| 23 |
the symbol in .config is CONFIG_SCHED_SMT. Again, it should be disabled |
| 24 |
for true AMD64s, possibly enabled for certain Intel CPUs. |
