| |
I'm trying to add compiling with -march=native to the kernel. The problem is that then some config options become discoverable at the beginning of the compilation. For example, CONFIG_X86_L1_CACHE_SHIFT=6 can be derived from "--param l1-cache-line-size=64". I suspect this is no-go, because all the dependency logic must be duplicated somewhere else (in the march=native script) for the above to work.
Is there any cleaner way I'm missing?
In theory, such script could even turn off CONFIG_CPU_SUP_AMD if it detects Intel CPU.
