Hi Friends, |
| 2 |
I am having a machine with 2 x Xeon 2.8Ghz w/HT/EM64T. |
| 3 |
|
| 4 |
I am using the minimal-amd64 iso to boot up and install the machine and |
| 5 |
it's a sucess. |
| 6 |
|
| 7 |
But there's a doubt here.. |
| 8 |
|
| 9 |
During the installation stage, the kernel provided with the Minimal CD |
| 10 |
will actually tell 4 CPU. Correct as Real CPU + HT CPU. But when I |
| 11 |
booted the machine with my own kernel. It shows only 2. Here's the |
| 12 |
extraction of config.gz |
| 13 |
|
| 14 |
# Processor type and features |

| 43 |

| 44 |

| 45 |
CONFIG_SECCOMP=y |
| 46 |
CONFIG_GENERIC_HARDIRQS=y |
| 47 |
CONFIG_GENERIC_IRQ_PROBE=y |
| 48 |
CONFIG_ISA_DMA_API=y |
| 49 |
|

I have the same problem before when I try to compile kernel-2.6.12.5 in |
| 51 |
FC4 with a P4 3.0 w/HT. I also lost the virtual CPU. |
| 52 |
|
| 53 |
Did the kernel-2.6.12.5 treat HT CPU differently ? |
| 54 |
|
| 55 |
I hope I can find the answer in the kernel changelog. But it's quite |
| 56 |
impossible for me right now. Any ideas ? |
