Router shows another CPU

Hardware Questions and Recommendations

Hi,

I have this router, Xiaomi R3G v1:

Running the latest stable: 21.02.2 version.

It is supposed to be dual core 880mhz.

But, when I run cat /proc/cpuinfo I get this:

root@main:~# cat /proc/cpuinfo
system type             : MediaTek MT7621 ver:1 eco:3
machine                 : Xiaomi Mi Router 3G
processor               : 0
cpu model               : MIPS 1004Kc V2.15
BogoMIPS                : 581.63
...

And it actually shows me 4 cpus each with 580mhz.
Is that a bug?

Thank you

/proc/cpuinfo shows "execution units", essentially virtual processors, and every thread will show as a such a unit. MT7621AT has two physical CPU cores with two threads each, resulting in four execution units. Look further down in cpuinfo, for every unit under "core" it tells you the physical CPU core it is running on.

BogoMIPS are not MHz, they're just bogus.

Thank you very much for the answers.

I started to get interested in the CPU because ever since I upgraded my openwrt to version 21.02 I got 350mbps~ where I usually got around 500 before. The CPU was clogged with around 350. I later enabled the hardware offload and it got back up to 550mbps.

I need to check the implications for enabling since I want to also enable vlans.

Again thank you for helping :slight_smile:
