AMD, Intel, Red Hat, and SUSE have defined a set of ["architecture levels" for x86-64 CPUs](https://developers.redhat.com/blog/2021/01/05/building-red-hat-enterprise-linux-9-for-the-x86-64-v2-microarchitecture-level/). For example `x86-64-v2` means that a CPU support not only the basic x86-64 instructions set, but also other instructions like SSE4.2, SSSE3 or POPCNT. How can I check which architecture levels are supported by my CPU?
