HakiOS
Apple's open-source Darwin kernel (XNU) on Android phones with a Qualcomm SoC, the way Android is Linux on phones: a boot loader of its own, drivers of its own, a configuration system and a version of its own. The same kernel runs in QEMU with nothing of Apple's and nothing of any phone's.
Where to start:
- Getting started: the open kernel in QEMU in a few commands, or the iOS 16.5 user space you lay out yourself.
- On the phone: the POCO X5 Pro 5G, in RAM with
fastboot boot, back to Android with a reboot. - Port a device: a device is a repository of its own over the common one: a defconfig, a status file, its drivers.
- Reference: every driver, configuration symbol and boot argument, made from the source.
What works
The table is made from the devices' own device.conf: all devices.
POCO X5 Pro 5G (redwood) |
QEMU virt |
|
|---|---|---|
| Lock screen, home screen, the stock apps | yes | yes (slow: the CPU is emulated) |
| Touch, buttons | yes | yes (the mouse and the keyboard) |
| GPU (OpenGL ES through Mesa) | yes | no |
| Metal | partly: a device that Metal loads (seen in QEMU); buffers and libraries written, checked on a Mac only; nothing drawn (plan) | partly, the same |
| Wi-Fi | yes | yes (virtio-net) |
| Sound, microphone | yes | sound only (virtio) |
| Cameras, vibration | yes | no |
| Flashlight, temperature guard | partly: written, some of it seen (redwood) | no |
| Cellular | partly: the modem is up and sees the network; no registration yet (cellular) | no |
| Bluetooth | no | no |
The three layers
- The open core: the kernel port, the loader, the drivers, the tools. All source, in these repositories.
- What you put on top: the kernel can start a user space you supply; it was built so that it can start iOS 16.5's, which you lay out yourself from Apple's own download. None of it is in the repositories.
- Apple's services (activation, Apple ID, iCloud, the App Store): not supported and not a goal.
By default nothing is installed: the loader goes into RAM, the system lives in RAM for a session, a reboot gives the phone back to Android. What is and is not written to a phone: Architecture.
The repositories
| Repository | What |
|---|---|
| hakios | common: the kernel port, every common driver, the loader, user space, the tools, this documentation, and devices/qemu |
| hakios-sm7325 | POCO X5 Pro 5G: its defconfig, status, UEFI platform, firmware script, and its SoC's layer (soc/: the Qualcomm SC7280 family) |
| hakios-uefi | HakiOS's UEFI: Mu-Silicium with HakiOS's boot path, banner and name |
devices/manifest.conf in the common repository names each one and the revision it is at; tools/hakios-device.py sync clones them
into devices/ and uefi/. One repository per device: it carries its SoC's layer, and tools/hakios-device.py new makes one. How the repositories fit.
