I'ts been a fairly long time since i've used this acc but one of my friends told me I should promote a project i've been working on, so... yeah!
I wrote a 3ds homebrew that boots a full linux environment in a risc v emulator in a few c files and only aboout ~170kb of code including all of the builtin nonessential example stuff like a js environment, fizzbuzz, cli doom, and more.
it's called 3DS-CLI, and it can be installed from universal updater or built from source and manually installed, and it's all open source cause free software is awesome!

please interact with the github repo if you like it!

I am Director of System Architecture at SCI Semiconductor and a Visiting Researcher at the University of Cambridge Computer Laboratory. I remain actively involved in the #CHERI project, where I led the early language / compiler strand of the research, and am the maintainer of the #CHERIoT Platform. I was on the FreeBSD Core Team for two terms, have been an LLVM developer since 2008, am the author of the GNUstep Objective-C runtime (libobjc2 and associated clang support), and am responsible for libcxxrt and the BSD-licensed device tree compiler. Opinions expressed by me are not necessarily opinions. In all probability they are random ramblings and should be ignored. Failure to ignore may result in severe boredom and / or confusion.

When we originally created #CHERIoT, we added an instruction to make accessing globals uniform with respect to the rest of RISC-V. We fairly quickly realised it wasn’t a great design, but the toolchain changes required to eliminate it took a while.
We’ve finally done it and I spent a bit of time this week writing up our journey. Removing this instruction is something we always planned to do before rebasing on the upcoming RV32YE base.
