I never missed a Makefile option to disable it. Of course, changes of vl.h are somehow annoying when they force a rebuild of nearly everything. But in most cases I focus on one target architecture (e.g. mipsel-softmmu), so compilation takes not much time even when everything is compiled. And you always can make a "touch *.o */*.o" if you know what you do and want to prevent a new compilation (or use a private modification of the Makefiles). Options make things more complicated - I don't think we need one here. >> How should we split vl.h into smaller pieces? Give each device a >> header file, like m48t59?

So you can group headers - one header for network emulations, one for graphics, ... We had this discussion about splitting vl.h before, and I still think it would be good. > > Regards, > > Fabrice.
