eos v0.2.0 — Display Subsystem

What's New

Display Subsystem (NEW)

• HAL dispatch fix: All display/touch/GPU/HDMI stubs now dispatch through registered s_ext_backend vtable
• HDMI vtable: Added HDMI function pointers to eos_hal_ext_backend_t
• Linux framebuffer backend: /dev/fb0 driver with double-buffering, RGB565/RGB888 conversion, evdev multitouch
• SDL2 simulator backend: 800x480 window with mouse/touch input for desktop development
• Composite backends: eos_backend_linux_desktop_register() and eos_backend_sdl2_register()

Product Profiles

• NEW: desktop.h — 1280x720 RGB888, display + touch + UI enabled
• Updated: Added EOS_ENABLE_UI 1 to cockpit, infotainment, hmi, watch, mobile, gaming, ev profiles

Files Changed

• hal/include/eos/hal_extended.h — HDMI vtable addition
• hal/src/hal_extended_stubs.c — Backend dispatch for 21 functions
• hal/src/backends/ — 6 new backend files
• products/desktop.h — New desktop profile
• 7 product profiles updated with EOS_ENABLE_UI
