Hyperthreading is disabled - sees just one core

Postby Jacek13 » Mon Nov 20, 2017 3:58 pm

. This is my first time with debian-based system, and for some reason it doesn't see 2nd thread of the CPU on Nokia Booklet 3G with Intel Atom Z530. I have a 3.16.39-1 kernel. Is it because I don't have Intel microcode installed? It wasn't necesary on ,,normal" LM.

Code: Select all

Architecture:          i686
CPU op-mode(s):        32-bit
Byte Order:            Little Endian
CPU(s):                1
On-line CPU(s) list:   0
Thread(s) per core:    1
Core(s) per socket:    1
Socket(s):             1
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 28
Model name:            Intel(R) Atom(TM) CPU Z530   @ 1.60GHz
Stepping:              2
CPU MHz:               1600.000
CPU max MHz:           1600,0000
CPU min MHz:           800,0000
BogoMIPS:              3191.83
Virtualization:        VT-x
L1d cache:             24K
L1i cache:             32K
L2 cache:              512K

Edit: Can it still be the case that 32bit kernel doesn't support SMT?!
