Re: ht CPU flag

To authors of /proc/cpuinfo:

Plz, fix stepping identification:

It might be a bug in the kernel code, however it is pretty unlikely: It just
reads what the CPU reports. You have an odd chip, nothing what the kernel
can do about. I see "family 15, model 2, stepping 4" usually beeing a P4
2.4GHz CPU. Maybe thats one of those relabling cases.

The information you list is a dual-cpu with HT configuration.

You could give us the output of any of your windows tools, but I am quite
sure they will report the same thing.

The problem of getting windows utility output now is that it's the server in the datacenter, running 24/7 for many users. That's why I wanted to find out everything just in Linux.

This server is on Intel mainboard with Intel chassis, but it's not compatible with Win2k3, that's why they gave it to me for Linux :) Sometimes it's unstable under Linux too. I feel that the problem is in the hardware, may be CPU settings, cache etc... I set "acpi=ht pci=routeirq" to make it work at all. It has newest available BIOS installed.

Here is what Intel say about supported CPUs for this mobo:

SL623 2 GHz N/A N/A 400 MHz 0.13 micron B0 512 KB Micro-FCPGA 0F24
SL5Z9 2 GHz N/A N/A 400 MHz 0.13 micron B0 512 KB Micro-FCPGA 0F24
SL6YT 2 GHz N/A N/A 400 MHz 0.13 micron D1 512 KB Micro-FCPGA 0F29h
SL6JY 2 GHz N/A N/A 400 MHz 0.13 micron C1 512 KB Micro-FCPGA 0F27h

But none of them has HT! And my configuration - has! It's a puzzle for me.


From now I'll use Intel recomendation to run their utility to resolve all
questions.

You mean this, right?

Yeah. Definitely Intel has some secret tables to identify CPU :)
