[linux] Can't recognize the cpu name correctly on arm64.

[xzl01]

Sorry I didn't follow your feedback format. I noticed that on Huawei Pangu ARM machines the CPU name is output as unknown:

But the name output on the lscpu is correct, After looking at the code I realized that the lscpu does something special for arm64 cpus https://github.com/util-linux/util-linux/blob/87f491671efb920ddd1c45c70dc8016f072851bb/sys-utils/lscpu-arm.c

Hopefully fastfetch will also support recognizing

[CarterLi]

I will just call lscpu and fetch its output

[danie-dejager]

I have output from lscpu on the AWS t4g here: #566

[CarterLi]

What's lscpu -p=MODELNAME?

[CarterLi]

Tested on Android, lscpu prints different model names for different cores. In this case should fastfetch use only the first name, or print them all?

[danie-dejager]

lscpu | awk '/Model name:/ { print $3 }'
Neoverse-N1
lscpu -p=MODELNAME
lscpu: unknown column: MODELNAME

[CarterLi]

What's lscpu -h?

lscpu | awk '/Model name:/ { print $3 }'

I can't use that, because the property Model name is localized in different locale.

[CarterLi]

Seems that CPU part is id_part::id in lscpu-arm.c. I decided to use it.

We can't use code of lscpu because of the GPL license issue.

This is the output of my lscpu:

Does lscpu -p=MODELNAME work?

[xzl01]

Does lscpu -p=MODELNAME work?  lscpu -p=MODELNAME 有效吗？

no

lscpu: unknown column: MODELNAME

[CarterLi]

Strange. Maybe you are using an old lscpu version

[xzl01]

It's possible, the version I'm using is 2.38-5 but I'll update it soon when I realize

[danie-dejager]

lscpu --version
lscpu from util-linux 2.37.4

[CarterLi]

Please test it

[danie-dejager]

Working for me:

I would prefer that lscpu output always be default on arm (armv6/7/8/9)

We can't use code of lscpu because of the GPL license issue.

There is a BSD clause 3 licensed version of lscpu too.

EDIT: Not sure whether it would work on Linux, though.

It's for x86 only
