Blinky 2.0: Graphics Acceleration on Zephyr RTOS
summary
Proposes a Zephyr graphics subsystem that exposes actual accelerator features: pxp and dma2d can do rotation scaling and colorspace conversion and can write directly to a display to save SRAM; Vivante/GC series support vector paths and gradients. API draft implements a queued render/flush model and a virtual GPU driver that routes operations to the best engine. Code exists as API structs and an initial RFC stage; no full upstreamed backends yet and LVGL module in Zephyr lags upstream.
