Whilst the /proc/cpuinfo virtual file on my Raspberry Pi 3 running
SLES12 SP2 (from SUSECON 2016) has the four processor sections none of
those sections includes the ‘model name’ line.
The file is also missing ‘Hardware’, ‘Revision’, and ‘Serial’ lines from
the end of the file.
Presumably this is known and will be resolved in a later build/update?

The format of /proc/cpuinfo varies on different architectures. On s390x for example, it looks like this: [QUOTE]
$ cat /proc/cpuinfo

For AArch64 (64bit ARM), the format is pretty simplistic and doesn’t mention much real information apart from the core id:[QUOTE]

An alternative source for now for AArch64 (until it switches to ACPI for some systems) is to look at the device tree manally:[QUOTE]
