02:58 cheapie        RVController doing something at least vaguely game-related, in this case calculating how many items a drawer (from LNJ's drawers mod -  https://content.luanti.org/packages/LNJ/drawers/ ) can hold with specified upgrades: https://cheapiesystems.com/media/2026-05-14%2021-55-21.webm
03:02 cheapie        GitHub is having problems again, so... here's a tarball of my working tree instead, source for the current thing is in drawercalc/drawercalc.c: https://cheapiesystems.com/media/rvcontroller-c.tar
03:06 cheapie        It's kind of fun running "make dump" (riscv32-none-elf-objdump -d drawercalc.elf) - not only does it have a tendency to try disassembling data out past the end of the readint() function since I don't have it separated, but it's actually using some instructions from some of the more recently-added extensions, like sh3add (from Zba) and zext.b (from Zbb)
03:24 cheapie        Looks like I'm up to 2213 lines of code to... ask the user for some numbers and then do some simple math on them :P

17:11 cheapie        RVController now passes the RISC-V architectural certification tests for the RV32I base instruction set and the M extension. Haven't managed to get the tests to cooperate with the other extensions (they won't even build for C...) for whatever reason
17:12 ireallyhateirc RISC-V emunation in Luanti when?
17:12 cheapie        That's what RVController does
17:12 cheapie        Runs in a Luacontroller, emulates (currently) RV32IMCB_Zicntr_Zicsr_Zifencei_Zbkx
17:13 ireallyhateirc well I expected no less of you
17:14 cheapie        A and Zbkb extensions will probably be next to implement
17:14 ireallyhateirc do a controller for a nuclear reactor next
17:14 cheapie        That sounds like an lmisu thing
17:17 cheapie        TBH my current "this sounds like a bad idea but also like enough fun that I might do it anyway" idea is a 6502 emulator to run inside RVController, since diceLibrarian asked me for a 6502 emulator a while back and this seems like a sufficiently silly way to do that
17:17 cheapie        I would need to get more familiar with the 6502 first though
17:22 ireallyhateirc do a PDP-8
17:23 cheapie        meh
17:23 ireallyhateirc just joking, whatever you make it's up to you
17:25 cheapie        I've been kind of thinking of some way I could serialize a table on the C side to deserialize on the Lua side (and vice-versa), as it would be useful to have some ecalls to send/receive digilines table messages (instead of just strings), but so far I haven't come up with any idea that wouldn't be a huge mess
17:44 diceLibrarian  [5/15/26 13:17:24] <cheapie> TBH my current "this sounds like a bad idea but also like enough fun that I might do it anyway" idea is a 6502 emulator to run inside RVController, since diceLibrarian asked me for a 6502 emulator a while back and this seems like a sufficiently silly way to do that \\ I have been summoned?
17:48 cheapie        diceLibrarian: yes
