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
thanks for that link.
$ /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)
whow, thanks a lot for that clear and detailed explanation. now i understand. funnywise my notebook CPU reports the same result as yours, seems to be the same family: x86-64-v4 x86-64-v3 (supported, searched) x86-64-v2 (supported, searched) Info:model:Intel Core i7-4700HQ bits:64 type:MT MCP arch:Haswell gen:core 4 level:v3 built:2013-15 process:Intel 22nm family:6 will we as end-users notice any difference in operation, when we install packages from that x86-64-v2 repositories? -- Best Regards | Freundliche Grüße | Cordialement | Cordiali Saluti | Atenciosamente | Saludos Cordiales *DI Rainer Klier* DevOps, Research & Development
