KianV StealthV — my custom quad-core RV32IMA RISC-V SoC on FPGA, running Linux SMP. Fixed-point bounce physics: gravity, impacts, squash and stretch. Four CPU-pinned threads render the floor, shadows and balls, including depth testing, directly to /dev/fb0. Precomputed lighting, no FPU.

Bros, remember Bruno’s world-famous donut? That was always kind of a benchmark for me. Bare metal on my 5-stage core. Now look at this shit. My custom SystemVerilog SoC, KianV StealthV, running quad-core Linux. MMU, memory bandwidth, audio, video. A complete system. And I’m still not done.

Yo brothers. I’ve been working on my quad-core again. Still no L2 cache for the moment. MP3 decoding, Bunny mesh in the framebuffer, X server, xeyes, analog clock with seconds, loader, CoreMark above 2 per MHz per core × 4, htop across all four cores. KianV Stealth

Pretty fucking cool to see 1.5473 CPI on this thing. Four cores, Linux, MMU, DDR3, caches, video, audio, networking, SDIO. When this project started, it was a bare-metal pipelined CPU running directly from block RAM. No DDR, no caches. Around 1.1 CPI.

I got to try the RISC-V board of my friend Hirosh. It includes an open-source Linux-capable RISC-V CPU with MMU! What's special about it is that this SoC has been taped out on the open-source GF180MCU process using wafer.space 🚀 Since we're in different […] [Original post on fosstodon.org]
The image shows that KianV is running Linux 7.1.0, the feature set of the RISC-V CPU and the motd, which shows the wafer.space logo with "KianVLinux" above it.

Finally turned my FPGA into a proper Debian machine. No more fucking BusyBox. Vim with syntax highlighting, Rust compiler, readelf, objdump, nm, GCC, G++, real Python. No MicroPython bullshit. Don't believe me? Here's the proof. Fucking awesome.

Looks like native GCC and G++ are now working on my dual-core. Fuck yeah. KianV. StealthV.

Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 29/08/2026
And the cool thing is, that’s with video, audio, networking, and all kinds of other stuff sharing the same memory bandwidth. That’s pretty damn cool.

Small update: I now have dual-core SMP with a CoreMark > 2, without an L2 cache. Pretty damn cool. KianV StealthV Gangster SoC

Quick KianV StealthV Linux SoC update: the dual core is now playing MP3s while rendering the MIT Bunny with Gouraud shading. Nice to see it all running together!

Still on vacation, bored, family’s not around… so I’m writing demos for my SoC because I don’t feel like doing logic design right now. 😄 StealthV This is a custom wizard.

NetBSD is now running on my 32-bit RISC-V KianV ASIC. As far as I can tell, this is the first documented case of NetBSD running on a physical 32-bit RISC-V ASIC. If anyone knows of an earlier one, please let me know. Many thanks to @mith.ro , and @mole99.fosstodon.org.ap.brid.gy

My custom RISC-V SoC, StealthV, is running Linux and rendering this Stanford Bunny demo at around 29 FPS. Audio playback is running in parallel, making this a great test of the complete system working together.

I just got my friend Leo Moser's custom GF180MCU Fabulous FPGA board, produced by WaferSpace. It already has a design loaded, so I'll be playing around with it over the next few days and see what I can build with it. A custom FPGA is just insanely cool. Leo is an absolute legend.

Bro... it's kind of crazy. You build a Linux SoC from scratch on an FPGA, get Linux running on it, and your original goal was simply to run a C64 emulator on your own Linux system. KianV StealthV.

MP3 playback under Linux while running X11 Another milestone for my custom StealthV RISC-V SoC. The system now plays 48 kHz, 256 kbps CBR MP3 audio entirely in software while running Linux and X11. No dedicated MP3 decoder. Everything is handled by my own RISC-V CPU and hardware.

Part 2: Doom under Linux with audio, not bare metal My custom Linux RISC-V SoC just became an arcade game machine. I originally set out to build a Unix RISC-V workstation. Now it runs Doom and Abuse under Linux on my custom StealthV RISC-V SoC.

My custom Linux RISC-V SoC just became an arcade game machine. I set out to build a Unix RISC-V workstation. Now it's running games on my custom Linux RISC-V StealthV SoC. The games run under Linux with virtual memory and render directly to the Linux framebuffer, not bare metal.

My KianV RISC-V ASIC is booting mainline Linux with SDRAM. Everything was developed from scratch. The board was made by @machdyne , and he also did the bring-up. Huge thanks to him! Damn... a 32-bit Linux machine running on my own ASIC. #RISCV #ASIC #Linux #SDRAM

StealthV can now edit C programs under X11 at XGA+ resolution, compile them with TCC, and run them. Not bad.

It’s alive, and I could probably push the clock another 10 MHz, but I’m not interested in that right now. We’re running at 24 MHz for the time being.
