Raspberry pi 3 B with Ubuntu 18.04 server arm64: what chip

How can I find what chip I have (what version of raspberry pi) with Ubuntu 18.04 server for arm64? What file can I check or what command can I run? /proc/cpuinfo does not have return useful information, just some generic details without mention of the pi.

The cat /proc/cpuinfo should produce a Revision number that corresponds to the board. See: raspberrypi.org/documentation/hardware/raspberrypi/…

It doesnt't, at least for Ubuntu 18.04 server. It only says "revision : 4".

The command lscpu is what you look for. Here's an example output of the command (taken on my Raspberry Pi 3B+):

lscpu

Which produces the following output:

Architecture:          armv7l

Byte Order:            Little Endian

CPU(s):                4

On-line CPU(s) list:   0-3

Thread(s) per core:    1

Core(s) per socket:    4

Socket(s):             1

Model:                 4

Model name:            ARMv7 Processor rev 4 (v7l)

CPU max MHz:           1200,0000

CPU min MHz:           600,0000

BogoMIPS:              38.40

Flags:                 half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32

Another option is the inxi command (you might have to install it if not present with sudo apt install inxi). The flags to use are as follows:

inxi -C

Which produce the following output:

CPU:       Quad core ARMv7 rev 4 (v7l) (-MCP-) (ARM) 

           clock speeds: max: 1200 MHz 1: 1200 MHz 2: 1200 MHz 3: 1200 MHz 4: 1200 MHz

As for identifying which chip is build on your board you can check the chip on the board as well the manufacturers website for info and as well as the different selling outlets for getting technical details.

Thank you, that definitely gives extra information. However, the model name when I run lscpu is listed as Cortex A-53, which is on both the pi 2 and 3 I believe. Do you happen to know of a more specific command/file which can distinguish between these two boards?

Normaly the board type and revision is printed on the board too, so you might be able to check that, otherwise I'm out of clues.

I see. I know what my board is, but a library maintainer needs this info to adjust his library to work with my hardware and software. Tried inxi, it also gives generic output only. Really appreciate the help though.

Otherwise your only option is to check the model number and so on from the chips body. There is not really much more information left to get. You can try sudo inxi -MCmG but on my raspeberry I got not much info out of this.

As for the library you want to use, there's only one question. is there a library which provides the same function you need or not. This is the information you can get from your machine program wise. On desktop computers there might be more information to get on the CPU version, the raspberry lacks in that regard a bit as putting all this information in some chips is adding to the costs.
