> They are moving all drivers to user space. probably you mean 3-rd party drivers? or even apple internally? [edit] i couldn’t tell that from the slides mentioned below, but maybe i missed something > All the ones corresponding to the former IO Kit do require C++ yea, which leads me to believe if apple was to rewrite the kernel, they probably would go with c++ ... or maybe it’s just that swift doesn’t have its embedded chops up to snuff yet... relevant slides: https://devstreaming-cdn.apple.com/videos/wwdc/2019/702vygott3n041/702/702_system_extensions_and_driverkit.pdf?dl=1 https://devstreaming-cdn.apple.com/videos/wwdc/2019/702vygot...

Watch the presentation, as it contains more information as the slides. The long term roadmap is as follows: 1 - surface kernel APIs for a specific driver model as userspace API 2 - deprecate for the respective OS release the kernel entry points related to the newly surfaced driver model 3 - remove the kernel api on the following OS release 4 - rinse and repeat untill there aren't any kernel driver APIs left The ones being released with Catalina are just the first wave.
