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.

Is there a good resource out there for wrapping my head around RISC-V? Last time I read a wiki my head hurt haha. Seems cool, though.
In principle it's just "slimmer ARM". RISC-V is also extremely dedicated to using memory mapped IO rather than older style IO x86_64 supports.
Think lots of registers, a fun zero register that is always zero, and memory mapped IO.
I for one think we need a register for each unsigned integer, why is zero so special? :P
Or if we can't get that, at least every power of 2 and power of 2 minus 1.
Maybe I can submit a proposal for risc-VI 🤣
No need! You can make your own custom extension! If the silicon doesn't support it, then you can provide firmware to emulate it.
I think a register for each of the primes should be enough.
ARM is also reduced-instruction set but I don't know how they differ. Is the instruction set somehow more reduced?
Aren't they more like a hybrid instruction set and architecture?
