I have an Ampere Altra-Max/INGRASYS Yushan Server System running Centos 8 stream.

Because we are a chip manufacteror, we don’t sell end systems, we provide a reference platform that is a starting point for our customers to make a product. This leads to bizarre set of internal versus external names. One thing that you can rely on, however, is the identifier of the processor itself:

# 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
...

TO make this readable, use the utility lscpu:

I want to build the latest Linus-repo Linux Kernel and run it on the server. Here’s the steps I went through.
