sorry to ask such dumb question, but what is a x86-64-v2 system?
There were a lot of discussions and really long threads to this topic in the last couple months, so I assumed this would be clear by now. Sorry for this. https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels
i know CPU architecures like ARM, x86 and x86-64
but what do you mean with x86-64-v2?
which CPUs belong to that category?
That started around Nehalem/Jaguar chipsets, back in 2009; Some might have come a bit later. Nevertheless, most somewhat decent machine will be v2 compatible (e.g my Notebook is from 2014 and supports even the v3 set)
and does every tumbleweed user know under which category the used CPU belongs?
Probably not - that's certainly going to be a fun challenge (see also my reply to Vojtech) The quickest ways to find out if your CPU is -v2 (or newer) are, on a current Tumbleweed system: $ /lib64/ld-linux-x86-64.so.2 --help This contains a section such as: Subdirectories of glibc-hwcaps directories, in priority order: x86-64-v4 x86-64-v3 (supported, searched) <-- My machine supports up to here) x86-64-v2 (supported, searched) <-- This is what Tumbleweed will require Alternatively, you can also use inxi: $ inxi -aC CPU: Info: model: Intel Core i5-4200U bits: 64 type: MT MCP arch: Haswell gen: core 4 level: v3 note: check built: 2013-15 process: Intel 22nm Here, level: v3 is the relevant piece (we will want at least v2) HTH, Dominique
