No, just added arch suffix into masterinclude.mk; and then rebuild all. > b) the kernel and modules has to be rebuild and packaged seperately? No, all building process for different kernels is done automatically for all packages.You just need to add package items into initrd and moddb. > c) all kernel related needs to be recompiled? After adding new arch - only packages that provide kernel modules must be recompiled, to make modules for that arch. Userlevel software isn't dependent against kernel configuration IMHO. > d) Do those packages have be provided for each arch or just the modules they > generate? Just modules.
