In some cases, that's > beneficial. It's possible to change and rebuild and update just the drm and i915, but you need to be careful to build against the same tree as the ones you are replacing. This is like using out-of-tree modules (which is something I can't recommend no matter what, but that's another discussion). However, this is completely different from planning to update drm and i915 modules on a running production system by unloading the old ones and probing the new ones. Don't do that. It will be a disaster. > Also reloadablility is always a good thing to have and I truly hope > Hajda/Iwai's patches would be accepted and merged. No downside of it > after all. I think it's good to be able to unload and reload modules for debugging and development, but not for normal use.
