6/6 Here's the code: github.com/IntegralPilo... The core changes described here are in the "apple-t8122" branch, while some hacks I needed to get the framebuffer to work for the nice demo are in the "rest" branch. This was a really fun side project to work on! Happy to answer any questions.

5/6 Finally, a driver had to be made for Apple's S5L UART. As fully talking to the USB controllers would be too much for this side project, I left m1n1 as hypervisor in EL2, and within EL1 Fuchsia talks to a virtualised Apple S5L UART which m1n1 sets up.

4/6 Another quirk with Apple's interrupts is that they route architectural timers and IPIs as FIQs instead of IRQs! I had to modify Zircon’s exception tables and interrupt masking to touch the F bit in DAIF and hook platform_fiq to use Apple's custom sysreg (S3_5_c15_c1_1)

3/6 One of the unique things about Apple's hardware is that they don't use the normal ARM interrupt controller (GIC). They have a custom interrupt controller, called the AIC. It needed a fully custom driver, and an increase to the Zircon MAX_INTERRUPTS, because M3 has 1,600!

2/6 For Asahi, we have a custom bootloader and hypervisor called m1n1. It can boot things using the ARM64 Linux Boot Protocol. Luckily, Fuchsia has a "boot shim" that can enable it to be started this way. But then, we have to teach Zircon about Apple's custom hardware.

Pink + Purple == Apple? 🌸🍎 Got Google's Fuchsia OS booting on an Apple M3 MacBook, through to userspace! Apple's interrupt controller (AIC), timer, and m1n1 virtual UART are working on native hardware. Here's how it works:

You can now install Linux on Apple M3 MacBooks! 🐧 We've got USB, Audio, WiFi, and more working, but not the GPU yet. Instructions to install in the reply. It was so fun to help make this happen, and credits to the rest of the team too! Let me know how you find it!

Raw data here! Note that this is JMH results, and real-world stats may vary. Link to the patch here: github.com/openjdk/jdk/... I recommend anyone reading this to get involved in OpenJDK, it is a really nice and welcoming community! You can learn more here: openjdk.org/guide/

8379327: 128-bit multiplication uses two multiply instructions on x86_64 by IntegralPilot · Pull Request #30174 · openjdk/jdk

Just got my first performance patch merged into OpenJDK. ☕ It fuses separate multiply instructions on x86_64, yielding a ~1.85x speedup for 128-bit multiplication on the JVM. Big thanks to the reviewers who helped guide this through!

A bar chart demonstrating:
For signed 128-bit mul: 1676.59 ns before vs 906.44 ns after
For unsigned 128-bit mul: 1675.90 ns before vs 901.73 ns after

In my repo, there's also a lot of other test cases verifying generics, ADTs and even real-world use cases like RSA encryption. Check it out here, and I'd really love if you could give it a star! github.com/IntegralPilo...

You can now run unsafe Rust code... on the JVM! I just shipped support for some basic unions (consisting of primitives and structs) to my project, rustc_codegen_jvm. Here's the test case that passes on CI JVM. Recently I also added support for function pointers and modules!

4/4 The trip was a cool experience! It was cool to see FPGAs in the wild in Waymo's autonomous fleet, and I was SUPER surprised by how smooth and futuristic they were. Hopefully they can come to Australia soon! And I had a lot of fun meeting new friends across so many different disciplines of STEM.

3/4 My FPGA resulted in a 8.6x improvement in performance per Watt compared to the RTX 3080 and involved a custom system architecture I designed, including a WebSerial (over USB-UART) dashboard to enable easy use and custom Rust-based firmware running on the Arm cores.

2/4 My FPGA project accelerated Cryo-EM, which won a Nobel prize in 2017 but is currently bottlenecked by Nvidia GPUs. I implemented a custom FPGA pipeline using a mix of VHDL and HLS C++, and took some inspiration from Apple Unified Memory and Systolic Arrays in Google TPUs

🧵Can electronics help with biological breakthroughs? I presented my Cryo-EM FPGA hardware accelerator project at #RegeneronISEF 2026 in Phoenix! It was such an awesome experience to meet so many like-minded students. I was honoured to come 2nd place in my category and get some special awards too.

Awesome Asahi progress update just posted by James, if you'd like to see what we've been up to recently! GPU stuff is SO fun and happy to answer any questions about it or anything M3. :) asahilinux.org/2026/02/prog...

Porting Linux to Apple Silicon

Michael Reeves @integralpilot.bsky.social · 27/01/2026

Linux is a free and open source operating system that is fully customisable and openly developed by a community. This does some of the work towards letting people who would like to run Linux on their Apple Silicon Mac devices do so!

Michael Reeves @integralpilot.bsky.social · 27/01/2026

Some of the work carries over to help M4 bring up, which someone else really awesome is working on! I believe they currently have Alpine Linux running with some early features like SMP (talking to other CPU cores) and putting the CPU in idle working.

Michael Reeves @integralpilot.bsky.social · 27/01/2026

I'm actually really interested in GPU work, but we needed to do this early bring-up first. Currently I'm doing an early look into the GPU right now. :)

Michael Reeves @integralpilot.bsky.social · 27/01/2026

Internal display (though just a frame buffer, not DCP features yet), trackpad and keyboard are working, so not fully yet but enough to run a pretty functional OS. noopwafel actually just got WiFI working which is great! :)

Michael Reeves @integralpilot.bsky.social · 27/01/2026

Yes, should have clarified in the original post sorry! Hopefully GPU to come soon, still investigating that. I believed they changed the ISA so we have to modify our compiler, and I love compilers, so it should be fun! :)

Michael Reeves @integralpilot.bsky.social · 26/01/2026

On Apple M3, a Linux KDE plasma desktop under Fedora Asahi Remix is now WORKING! Super excited to share this update and happy to answer any questions! Co-credits to noopwafel and Shiz. :)

Just sent the Apple Silicon Power Supply driver I've been working hard on improving the last few days upstream to the main linux kernel, adding support for reading info about AC adapters and batteries, and modifying charge behaviour. Next upstreaming project is MTP! lore.kernel.org/asahi/202601...
