Hi Harish, I want to implement EGL_KHR_partial_update for lima mesa driver and find you worked on Android/Wayland support for it: https://patchwork.freedesktop.org/patch/160944/ https://patchwork.freedesktop.org/patch/188695/
So I have some question about it: your implementation seems to depend on platform (Android, wayland) support, for example call native_window_set_surface_damage() in Android implementation. What's the purpose of it, tell the Android SurfaceFlinger to redraw the damage region? And is this damage region the "surface damage" or "buffer damage" metioned in the EGL_KHR_partial_update? https://www.khronos.org/registry/EGL/extensions/KHR/EGL_KHR_partial_update.txt To my understand this extension should only depend on the driver support instead of platform support while the EGL_KHR_swap_buffers_with_damage is the opposite: https://www.khronos.org/registry/EGL/extensions/KHR/EGL_KHR_swap_buffers_with_damage.txt For lima implementation, I want to use the damage region (buffer damage) provided by EGL_KHR_partial_update to skip rendering of un-damaged region when eglSwapBuffersXXX. And tell damage region (surface damage) to compositor should be left to eglSwapBuffersWithDamageKHR provided by EGL_KHR_swap_buffers_with_damage.
