 - `_localmodcfg`: Only compiles modules found in modprobed-db's database (which decreases compilation time and kernel size)
 - `_use_llvm_lto`: Compiles the kernel with LLVM instead of GCC. Should work, if not open an issue
 - `_subarch`: Specifies the subarchitecture to compile for (see the [PKGBUILD file](https://git.staropensource.de/JeremyStarTM/aur-linux-clear/src/branch/develop/PKGBUILD) for a list of all subarches). Default is `41` (Generic x86-64), which is compatible with all amd64 processors. Must be a number
+- `_subarch_microarch`: Specifies the microarchitecture to compile for. Only applies to and is required by the GENERIC_CPU subarch. Must be a number between `1` and `4` ([click for more information](https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels))
 - `_debug`: Force enables debug options when set to `y`, force disables debug options when set to `n` or uses the config defaults when unset
 
 All of these variables just need to be set for them to apply, except for `_subarch` and `_debug`. See their descriptions for more information.
