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:
[root@eng14sys-r 111 ~]# lscpu Architecture: aarch64 Byte Order: Little Endian CPU(s): 80 On-line CPU(s) list: 0-79 Thread(s) per core: 1 Core(s) per socket: 80 Socket(s): 1 NUMA node(s): 1 Vendor ID: ARM BIOS Vendor ID: Ampere(R) Model: 1 Model name: Neoverse-N1 BIOS Model name: Ampere(R) Altra(R) Processor Stepping: r3p1 CPU max MHz: 3000.0000 CPU min MHz: 1000.0000 BogoMIPS: 50.00 L1d cache: 64K L1i cache: 64K L2 cache: 1024K NUMA node0 CPU(s): 0-79 Flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm lrcpc dcpop asimddp ssbs |
I want to build the latest Linus-repo Linux Kernel and run it on the server. Here’s the steps I went through.
