Please refer to the Linux build guide for more information.') >=20 > The other thing we need to discuss is the fact that we're changing the be= havior in this patch from machine=3Dnative to platform=3Dgeneric (and the i= mplied cpu_instruction_set=3Dgenetic which equals to machine=3Dgeneric). We= need more feedback on this - Thomas, David? Should we include more people?= The reason for this change is we want the build without any meson options = (specified on cmdline) to be usable on as many different machines of the sa= me architecture (this is my understanding form the discussion with Bruce), = which is the generic platform. We could preserve the current behavior by se= tting the default to native, so we just need more discussion. I don't understand why you need to change the behaviour. If we change the behaviour, it must be done carefully after a deprecation notice and an agreement of the Technical Board.
