I have released Sentinel v0.1.0-beta.2.

Sentinel is my microcoded RISC-V CPU core written in Amaranth. It fits in ~1000 LUTs and ~400 FFs on an ice40 FPGA, and implements RV32I_Zicsr and the Machine Mode privileged spec, and passes the RISCOF and RISC-V Formal test suites.

Ready-to-use Verilog is available here: https://codeberg.org/cr1901/sentinel/releases/tag/v0.1.0-beta.2

Sentinel is also available on PyPI now: https://pypi.org/project/sentinel-cpu/

If you wish to play with the source, follow the Quick Quick Start:

(This is NOT RISC-V bashing. I don't know enough about vector code to have an opinion):

> RISC-V is very different in this respect: the best specialists on the planet are getting together to design the RISC-V ISA, and decades of lessons learned are taken into account in its design.

Okay. Then why does basically everyone I talked to, who I think are competent software engineers, hate the V spec?

Public service idea: Send me your floppy disks for postage (to and from), and I'll send you the files via email or temporary storage (if I can read them).

msp430 Rust probably isn't gonna last much longer... I don't have the bandwidth to fix the gcc port (rustc calls the compiler driver for linking) or to add lld support.

Fun while it lasted, but not enough ppl care about the 16-bits. That includes myself at this point. It's just too much work that I'm unwilling to put in without help.

I hate how much we collectively focus on depth instead of breadth now. Now only x86 and ARM get the love.

Very good day for working on Sentinel. I cut a release (don't use it), and basic Forgejo CI is working. I'm even uploading to TestPyPI now!

I think I'll have to wait until larger runners are available to enable CI fully though.

This is how I figure out that I can type the name of one of my computers without the ".lan" TLD into my web browser, press Enter, and it Just Works*.

* If I spun up an http server on said machine.

I have new wrinkles under my eyes after that week of CI hell. Wonder if I have my first grey hairs now too...

cc: @ldcd Just an FYI, the import name for Sentinel will change from sentinel to sentinel_cpu for the release after this upcoming one: https://codeberg.org/cr1901/sentinel/issues/88

If you can, I'd suggest holding off on updating until I do another release, which shouldn't be long (famous last words). That way you have time to change the import name :D!

https://code.forgejo.org/forgejo/runner/pulls/1388 At least this is a legitimate bug (Codeberg uses v12.6.3), and not me losing my grasp on real- oh, who am I kidding?

Mom just told me about this... Oh My God, It Was A Real Thing ._. ...

Anyone else on Codeberg using codeberg-medium runners (i.e. Forgejo Actions, not Woodpecker)... are you able to get jobs onto the medium runners today? Mine all seem to be stuck...

I am SO Goddamn tired of this timeline...
