Vulkan capabilities on Android phones — drivers, runtimes and the compatibility layers above them.

POWERED BY [mikey:hexoid-sys] — the brand of the advanced builds:
long research, testing and verification — advanced tools and structures.

I work on the layer between a phone's silicon and the software people want to run on it: graphics and compute drivers, the runtimes that talk to them, and the compatibility layers that carry Windows and Linux applications onto Android.

The development target is a Snapdragon 8 Gen 3 platform: Adreno 750 GPU, Hexagon NPU and Kryo CPU, with Vulkan as the API of record through Turnip and Mesa, and glibc and bionic as the two C libraries the same kernel has to satisfy.

Everything here is active engineering work, described as such — not certified results, not benchmark claims. Where a number appears, the method behind it is published with it.

Every repository on this account is my own work — designed, built, tested and documented by me. POWERED BY [mikey:hexoid-sys] does not mark ownership; it marks the highly advanced projects: the few where a long period of research, analysis, study and learning came before the build, and where the result has been tested and verified rather than merely published.

The mark therefore stands for a complete engineering build — the four conditions below — and it is deliberately narrow. Utilities, experiments, studies and archives on this account are just as much my creations; they simply do not carry the mark.

A repository carries the mark only when all four conditions hold:

Applied to: the advanced builds — a compiler and toolchain, a bench instrument, a biosignal acquisition chain. Each of them took long research, repeated analysis and a verification pass before the mark was applied.

Not applied to: utilities, one-liners, experiments, studies and archives. They are my work as well; they are published under Other work without the mark.

1 · problem       a workload that does not run, or a bench measurement that does not exist
2 · architecture  which layer owns the job, what each layer may assume, where it will fail
3 · drivers       Vulkan / OpenGL / OpenCL paths — correctness before speed, validation on device
4 · hardware      silicon limits, board bring-up, power and thermal budget — calculated, not guessed
5 · tooling       reproducible build path, pinned versions, scripted install
6 · evidence      measured numbers, checksums, and a self-check that runs on every push
7 · honesty       limits, safety rules and licence stated in the repository

Every tool, driver, runtime, library and piece of silicon the work is built on — drawn as a relief mark, one per component. The same twenty marks form the poster above and are stored in assets/toolchain/ with an index.

Vulkan	Snapdragon 8 Gen 3	Adreno 750	Hexagon NPU	Mesa
Turnip	Zink	rusticl	OpenGL / GLES	OpenCL
Linux kernel	glibc	bionic	Android	Termux
Termux:X11	Box64	Wine	WoW64	Hardware acceleration

The emblems are original stylised symbols drawn for this repository by tools/emblems.py — not vendor artwork. They identify the components; they do not imply affiliation or endorsement by the projects named.

• Vulkan on Adreno — Turnip feature exposure, extension support and validation; version and profile work against what the hardware can hold; memory model, synchronisation and cache behaviour before throughput.
• Mesa user space — Zink (OpenGL on Vulkan), rusticl (OpenCL on Mesa), Gallium state trackers, shader caches, and isolating a driver fault down to a single call.
• Kernel and hardware acceleration — DRM / MSM power, scheduling and buffer handling; Adreno 750 and Hexagon utilisation and offload; where acceleration is real and where it silently falls back.
• Platform and compatibility — Termux and Termux:X11 for a Linux user space and a desktop on the phone, Box64 for x86_64 binaries, Wine + WoW64 for 32-bit Windows software in a 64-bit container.

These repositories are my own work as well — published on their own terms as utilities, experiments, studies and archives. They do not carry POWERED BY [mikey:hexoid-sys], because the mark is reserved for the advanced builds described above.

• Issues first. A bug report with the platform, the version and the first error line gets answered fastest.
• Reproducibility matters. Pin versions, publish commands, include checksums.
• No medical, certified or guaranteed claims. Where a project is experimental, it says so on the front page and in the licence.
