Roadmap

[YannMagnin]

This is a roadmap issue.
May change really often.

Schedule

See milestones

• 0.0.15 - rework hypervisor
• 0.0.14 - rework kernel allocator
• 0.0.13 - cleanup the codebase (action, unit tests, ...)
• 0.0.12 - kernel boot rework
• 0.0.11 - support kernel image generation
• 0.0.10 - support the fxcp400 (bootloader)
• 0.0.9 - project rework

Status (0.0.13) - cleanup the codebase (action, unit tests, ...)

• CI/CD
  • create a custom docker image which contain the toolchain
  • create a job that check code valitity (pylint, mypy, ...) on each commit
  • create a job that run unit tests on each commit
  • create a job that generate all kernel images (artifact)
• vxSDK
  • re-enable unit-test custom framework
  • re-support bootloader console unit-tests
  • add some other unit-tests
• HolyHook2 support for fxcp400
  • install HH2 on real device
  • resolve missing symbols for the bootloader to run
  • use the BackupVRAM() as a kernel loading base address
  • create a generic (weak) kernel jumping function (use a custom one for the loading the kernel in BackupVram)
  • validate the HH2 support
  • validate that my CFW support is not broken

Previous roadmap

0.0.12 - kernel boot rework

• code cleaning
  • unify all kernel entry (currently board-specific)
  • define a boot procedure (what must be archived during this step)
  • add a custom ulibc with critical function (e.g. strlen, memcpy) to avoid collision with the "real" libc
  • add information in README which explain that a lot of file are PoC and mainly not used here
• kterm device
  • create the kterm device to allow display early log information
  • the device must be independent from the display module
  • the device must support scrolling mechanism
  • the device must support proportional font
  • support the fxcp400 device
  • support the fxcg50 device
  • support the fx9860 device
• optimisation
  • support Link Time Optimization (LTO)

0.0.11 - support kernel image

• SDK kernel building support
  • support kernel initialisation (module and driver selections)
  • support kernel font conversion (mono)
  • support kernel build system generation
  • support kernel building
  • support kernel image (ASLR)
  • support bootloader image (ASLR + kernel image information injection)
  • support os image generation
  • validate bootloader inforation
  • implement kernel jumping
  • validate the kernel booting
• support device
  • support the fxcg50
  • support the fxcp400
  • support the fx9860
• bootloader
  • support custom command registration
  • support custom command invokation
• project
  • add README

0.0.10 - support of the `fxcp400`

• exploit the device
  • find a way to execute arbitrary code (since the device does not allow third-party program)
  • find a way to execute privileged instruction (theoretically provided by default)
  • reverse file primitives (at least open, read, write, close)
  • reverse screen primitives
  • reverse keyboard primitives
• support the device
  • support the bootstraping part (early-boot)
  • implement screen driver (no touch-screen support)
  • implement keyboard driver
  • successfully boot the bootloader
• SDK change
  • unify the board init and board select
  • catch missing toolchain error
  • review all CLI entry to force use the logger
  • review all typing import

0.0.9 - project rework

• move project management in Github
• complet rework SDK abstraction
• remove vxSDK dependencies
