Hello,

I have a question what does the 8 mean?

[nicolargo]

Perhaps in /proc/device-tree/model ?

@jslegers73 can you have a look ?

[jslegers73]

@nicolargo this is the result
pi@rpi-test:/ $ cat /proc/device-tree/model
Raspberry Pi 4 Model B Rev 1.2
pi@rpi-test:/ $

I have the same issue on an Oracle Cloud VM:

❯ cat /proc/cpuinfo
processor	: 0
BogoMIPS	: 50.00
Features	: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm lrcpc dcpop asimddp ssbs
CPU implementer	: 0x41
CPU architecture: 8
CPU variant	: 0x3
CPU part	: 0xd0c
CPU revision	: 1

Obviously not much of this is useful but lscpu does give me a model name, would this be a possible fallback option?:

❯ lscpu
