Roadmap

What works is in docs/STATUS.md (every row says whether it was observed on hardware, read from source or is a guess). This page lists what comes next. Order and estimates are guesses, not promises.

Milestones

  1. iPhone GUI on the Pixel 6a: reached (2026-10-22). Lock screen, home screen, Settings, touch.
  2. Wi-Fi: not started on hardware. Broadcom BCM4389 on PCIe; plan in docs/research/20-wifi-stack-plan.md.

Now (demo and release)

  • Power-on boot without a PC: iOS image in boot_a, stock boot_b kept as the way back, slot switched with fastboot --set-active.
  • Pixel 6a identity in Settings -> About (name, model, serial text), plain lock-screen clock. Built, waiting for a hardware check.
  • Publish this repository.

Next

  • Smoother UI. Software rendering is slow. Cheap steps first: vsync period in the framebuffer notifications (patch 0101, built, not measured), frame statistics, then profiling what burns the CPU.
  • Boot selector. A way out of iOS without a PC (a key held at boot returns to fastboot), later maybe dual boot with a separate data partition.
  • Remote reset to the bootloader over the USB network (patch 0100): written, one inconclusive hardware run.
  • mac-address entries in the device tree (removes 5 s waits in MobileGestalt), a real-time-clock service (removes a 30 s boot wait).

Later

  • Wi-Fi (milestone 2): PCIe/PHY bring-up behind EL3/ACPM, firmware handling, an apple80211 front end for iOS.
  • GPU: Mali-G78 power domain and clocks sit behind the secure world; research only so far.
  • Audio, Bluetooth, camera, sensors, modem. No work started.
  • Other Tensor phones (Pixel 6, 6 Pro share the SoC tree): see docs/PORTING.md.

Where help is most useful

  • Hardware captures from other Tensor devices (see CONTRIBUTING.md for how to submit them).
  • Reverse-engineering notes: PCIe/PHY init for the Wi-Fi chip, ACPM channels, Mali power sequencing. Cite your sources.
  • Host-side tests and tooling around the existing test loop.
