I haven't read the whole thread yet, so count me confused too, including that Paolo didn't reply to that part of the message at all. Whenever the question of a plugin system came up, it was mostly about desperate attempts to try to sneak GPL-incompatible code into QEMU. I doubt that is the case here, so I am not generally opposed. I assume your interest is rather reducing packaging dependencies for headless installs etc.? The only thing I was pointing out for now is that with regards to our build system our ship seems to have a slingering course, with objects originally being grouped by functionality/scope, then thrown into a big pot, now apparently being picked apart again. And implicitly I was hinting that there are people with out-of-tree patchsets that constantly need to rebase on these Makefile changes, me finding a whole Makefile.objs as conflict much more confusing to resolve than a new file not compiling due to some CPUState or QOM code changes. Not saying you shouldn't apply changes for cool features, please just coordinate with Paolo to avoid unnecessary back-and-forth in the build system.
