For the latter, the ability of reusing +device drivers from the Linux kernel plays a crucial role. Hence, the guide +presents Genode's practical methodology and tooling behind the black art of +transplanting and reanimating unmodified Linux kernel code into Genode +components. Along the way, there are countless little tips and tricks that +help to turn low-level grunt work into a fun and worthwhile experience. + +The document closes with a glimpse at real-world scenarios, culminating in +the setup the modem and the routing of audio signals to issue voice calls. + + Sculpt OS release 22.04 | 2022-04-28 ####################################
