rpm 4.19 multi x86-64 arch versions

[finjulhich]

I have a few hosts with cpus of different x86-64 levels 2 3 and 4.
I am working on producing rpms via cmake.

1. Can I produce fat rpm files, ie at install time, the correct version (arch level) of the binaries get installed?
2. Do provides/require take into account these levels?
3. Is this concept expandable to entirely other archs like ARM?
   Rds,

The arch levels are not a new feature, just new sub-architectures. Think i386 getting expanded to i486, i586 and i686 back then, and similar levels exist on arm already. The rpm arch only works as package level differentiator and to ensure you can't install a package eg for level 4 on a level 3 host.

Ok so in order to install on cpus of different levels, I need to produce rpms of differnet levels.
The level is encoded in the rpm file name?

Again, these are just (sub)architectures, and as always, the arch is present in the rpm package file name.
