When I executed the command:

sudo lshw | grep core

It's showing following output:

cores:2 cores_enabled:1 threads:2

How can I enable both cores? (Ubuntu 18.04).

Edit:

No options visible in BIOS

output for: cat /etc/default/grub is

grub result

output for sudo lscpu -a --extended is

lscpu result

    This probably due to a BIOS setting. Check in your BIOS if something like `multi-core support` is disabled and enable it. Or maybe [this](https://askubuntu.com/q/247028/968501). Or if not, please [edit] your question and add the output of `cat /etc/default/grub` – Raffa Apr 08 '20 at 21:30

    Or, it could be a bug/limitation of `lshw`. Try `sudo lscpu -a --extended` – waltinator Apr 09 '20 at 04:55
  • When I compared performance with same configuration device. Machine seems to be slower almost half. Is that an issue due to cores_enabled:1 – karun j Apr 10 '20 at 08:30

    Does `sudo lscpu -a --extended` show threads or CPU cores? – NessDan Apr 27 '21 at 17:07
