src/sys/arch/amd64/conf: MODULAR
Log Message:
An attempt to create a fully modular kernel by including GENERIC and
undefining all the drivers we have modules for. This is done to reduce
the kernel footprint for DTRACE and also to test that the modularized
drivers work. Current issues:
1. builtin drivers can't depend on modularized drivers (the modularized
drivers are attempted to load as builtins).
2. there is no way to "no define" drivers
3. it is not always obvious by their names which drivers/options correspond
to which modules.
4. right now critical drivers that would need to be pre-loaded (ffs,
exec_elf64) are still built-in so that we don't need to alter the boot
blocks to boot.
Ideally modstat should show none of the drivers as built-in but we are far
from that.
