2020's Motivations

• I was looking for a project to:
  • get busy during Lockdown s
  • build a product/prototype device
• Base for experimenting
  • catch up with modern technology
  • while keeping connection to "legacy"
• Think about sustainability
  • also in software or community domains

• Or Raspberry Pi 3+ new !

Hardware Support

• Most x86* PC (~2004)
• Raspberry Pi Single board computer
  • Pi3: ~20fps (professor)
  • Pi4: ~60fps to 20fps (gnu)
• More platform (SBC, GPUs)
  • Etnaviv, Freedreno, Panfrost…
  • SBC: STM32MP1, db410c, XU4…

Graphics stacks

• Update legacy OpenGL app to support SDL2
• SDL2 with more backends:
  • Wayland, X11, KMS/DRM, DirectFB
• New GLESv1 backend renderer
  • thanks Nicolas Caramelli (yagears)
• Pure Wayland with desktop OpenGL support
  • need patch libsdl-org/SDL#4358
  • Gentoo: "USE=-X" (thx @lanodan)
• Try Mesa3D/DRM new GPUs libre drivers

Try it

• Current release (SDL-1.2)
  • Debian-11 / Ubuntu-21.04
  • Docker, WLS with X11…
• Install snap snapshots for GNU/Linux
• Or rebuild:
  • Gentoo, OE's meta-games, BSD
• Build and boot OS image:
  • Using DebOS, Ubuntu Core, Yocto

Ubuntu Core

• Ubuntu for embedded (IoT)
• Mininal, Secured, with unattended updates
• snap based (use github for CI/CD)
  • pinball, pinball-table-{gnu,hurd} snapped
• Use mir graphical server
  • with wayland protocol
    • supported by SDL2
• BSPs: PC, RPi (armhf, arm64) and more

OE/Yocto

• Layer based Distro
• Select Board Support Package:
  • many supported platforms (intel, arm etc)
• Build for reference distro: "poky"
• Add meta-games layer:
  • https://github.com/cazfi/meta-games/
  • (bitbake-layers add-layer …/meta-games)
• Build also other derived projects: ie:
  • All Scenerios OS (formerly Open Harmony)
• Benchmarked SBCs (STM32MP1, db410c)

Sensor input

• "Nudges Controls" are not intuitive
• Rely on motion sensor is more natural
• Used NXP FRDM-K64F board (Thx NuttX/NXP)
  • MCU ships Accelerometer (FXOS8700Q)
  • Made a PoC on MBed OS using HID classes
  • Contributed driver to NuttX
• Could be ported to other HW or RTOS:
  • Zephyr, RIOT, FreeRTOS, TizenRT…
