repository is be repurposed to move forward with x86-64-v2, and
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.

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,
