As I can see, hw/ contains a wide variety of objects, which go into hw_arch, specific, softmmu or common.

There does not seem to be a common way to handle objects in hw/ .

In the case of hw/mips, it goes to hw_arch in meson.build, so it sees config target.

Other users of CONFIG_USER_ONLY in hw/ are arm semihosting:

semihosting/arm-compat-semi.c which goes to specific_ss

and hw/cpu.c, which uses CONFIG_USER_ONLY but does not see it, since it is a common_ss module.

So the uses of CONFIG_USER_ONLY in hw/cpu.c are wrong for sure, or at least until hw/cpu.c goes to common_ss.
It does not hurt because the tests are in the negative, and those sysemu-only / softmmu-only symbols are actually always visible, including for CONFIG_USER_ONLY.

Ciao,

Claudio
