From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why isn't there any hype on multikernel? (lemmy.ml)

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?

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.
