I’ve seen this video of Timothy Roscoe at USENIX ATC '21 recently and was very interested in multikernel OSes.
While Barrelfish is abandoned, it seems that Kirsch is his successor.
However, since I’ve seen this video I wonder what changed since the keynote, why it doesn’t seem to be a thing for mainstream kernels and if there was any roadmap/will to expand mainstream kernels like linux to embrace the whole hardware.
Do you have any pointers/ideas or resources to share on this?
What’s the use case?
Well, first you have the security view point as @DaPorkchop_@lemmy.ml explained with cross-SOC attacks. Then, if you consider the OS definiton given by Roscoe (which, imo, is a good one), then your OS is not FOSS at all! For instance, in your OS you would have to consider the DSP chip, with his bootloader and kernel as a part of your OS.
