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.
Since this was pretty much a clean install, I had none of the development tools installed, to include git. I’ll include here a couple other packages that I learned I needed later in the process. This is the set of successful commands I ended up running.
yum groupinstall "Development Tools" yum install openssl-devel yum install python3 yum install ncurses-devel #for menuconfig, which I didn't really need. dnf config-manager --set-enabled "powertools" yum install dwarves git clone https://github.com/torvalds/linux cd linux export NPROC=`nproc` yes "" | make oldconfig make -j $NPROC make -j $NPROC modules make modules_install make install grub2-mkconfig -o /boot/grub2/grub.cfg |
Before a reboot I get
[root@eng14sys-r111 linux]# uname -mrs Linux 4.18.0-365.el8.aarch64 aarch64 |
After a reboot my grub menu looks like this
CentOS Stream (4.18.0-365.el8.aarch64) 8 CentOS Stream (4.18.0-348.el8.aarch64) 8 CentOS Stream (0-rescue-306ea476c3584adea2089f1980a56ca3) 8 System setup |
At the start of the boot log I see
[ 0.000000] Booting Linux on physical CPU 0x0000120000 [0x413fd0c1] [ 0.000000] Linux version 5.18.0+ (root@eng14sys-r111.scc-lab.amperecomputing.com) (gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-13), GNU ld version 2.30-114.el8) #2 SMP Wed May 25 08:33:07 PDT 2022 |
After boot and log in:
