Who
I am the person who already said the quiet part on the Omnux umbrella post: M3 installs today, software-rendered, and software rendering is not a desktop.
This piece is for a narrower audience.
M3 owners who will lend a machine for m1n1 proxyclient captures. Reverse engineers who already know Asahi's AGX story on M1/M2 and want the T603x/T8122 delta wall documented without contamination. DRM and Mesa people who treat "working" as render nodes plus glmark on metal, not a README adjective. License hawks who care that MIT stays clean before src/ fills. Agent operators grinding capture loops under the same agent-army mandate that sits in Omnux GOAL.
If you need an install one-liner or a diagnostics tarball, see the sibling posts. If you need the GPU long pole named as a project with acceptance criteria, this is it.
What
I stood up omnux-gpu, a standalone MIT repo whose value is honesty about what is missing.
It is an attempt at a clean-room GPU driver for Apple M3-series silicon. License: MIT. Upstream may take everything; that is the point. The repository holds scaffolding, a research roadmap, tooling stubs, and eventually driver code. It does not yet contain a working driver. Nothing here claims otherwise until pixels appear on a physical M3.
Three reverse-engineering walls stand between scaffold and acceleration:
- Command processor submission model. How macOS userspace submits work to AGX firmware on T8122/T603x (differs from M2).
- Shader ISA deltas. M3 brought Dynamic Caching, mesh shaders, hardware ray tracing; instruction encoding moved vs M1/M2.
- Firmware interface. Version negotiation, queues, faults against shipping macOS AGX firmware (issues call 14.8.3+ as the field floor).
Each wall is only discoverable against real hardware, using m1n1's proxyclient tracing on a machine booted into macOS with instrumentation. Code written away from the metal is guesswork.
The method is a loop:
- Capture. Target M3 into m1n1 proxyclient from a second USB host; run macOS GPU workloads under
agx_*experiments adapted for newer ABI. - Diff. Compare to known M1/M2 models; land deltas in
docs/. - Implement. Clean-room sources in
src/from documented behavior only. - Validate. kexec Omnux kernel with the driver; iterate until DRM render nodes exist and glmark runs.
- Publish. Every milestone upstream to Asahi first.
Fifteen public issues map the work. Issues #1–#8 are the GPU spine: capture harness, submission-model docs, ISA delta docs, firmware-interface docs, DRM skeleton (probe + firmware load + first render node without claiming acceleration), Mesa Honeykrisp/agx bring-up for G15-class, t603x power/PMP/thermal, and a local validation harness (kexec + glmark2/vkcube to signed JSON, own metal, no hosted CI theater). Issue #9 is the license immune system: docs/CLEANROOM.md, PR source disclosure, taint procedure, before any non-scaffold code lands. Issues #10–#15 park SEP/TouchID research on the same tracker so the wall is visible; the biometrics frontier and omnux-report evidence collectors are sibling stories.
src/ is empty on purpose. Contaminated contribution (decompiled Apple code, NDA headers, GPL-mixed paste) poisons the MIT claim. The audit process has to exist before the directory fills.
Where
It lives where M3 metal and a second USB host can sit on the same desk.
Repo: michaelmonetized/omnux-gpu. Parent umbrella wires it as gpu/ under michaelmonetized/omnux. Diagnostics sibling: omnux-report. Logs, sysinfo, ADT helper, SEP collectors with redaction; useful for evidence, not a substitute for AGX traces.
SoCs in scope: T603x / T8122 class. Capture target: shipping macOS firmware on those chips. Validation target: Omnux kernel kexec'd from m1n1 until /dev/dri/renderD* appears and the acceptance harness stops lying.
If you have hardware to lend, the README says open an issue. That is the bottleneck.
When
2026-08-24. Single scaffold commit a3b7f74: MIT LICENSE, honest README, docs/NOTES.md placeholder, empty src/, stub tools/. Created the repo the day before the Omnux umbrella monorepo week. One commit. That is still the commit graph.
2026-08-25. Siege map lands as public issues #1 through #9 while Omnux M0 is getting wired. Capture harness called the critical path. Clean-room audit filed as blocking-by-convention and cheap: do it before code, not after a lawsuit hypothetical.
2026-08-26 to 2026-08-27. Issues #10–#15 add the SEP/TouchID research program to this tracker (T1 community win, T2 bridge, omnux-report SEP section, apstrand frontier notes). Useful adjacency. Still zero GPU capture artifacts under docs/captures/. Still no DRM skeleton. The calendar moved; the metal bottleneck did not.
2026-09-08. This pack. Still scaffold. Still fifteen open issues. Still waiting on an M3-class machine in the harness loop.
Why
Omnux can already tell the truth about M3 installs. Truth without a GPU project is a permanent software-render sentence dressed up as a roadmap.
I wanted a repo whose license Asahi can absorb without a negotiation. I wanted "working" defined as pixels and scores on metal. I wanted the three RE walls named so contributors argue about captures. I wanted the clean-room gate written before the first real C file, because MIT is easy to claim and hard to un-poison.
The ask is not stars. The ask is hardware in the capture loop, and issue checkboxes that turn green only when the acceptance criteria say so.
