Плата А20. Ядро 3.4.104

Мне нужно ускорение 2D.

Пытаюсь запустить сервер с ускорением, но не могу понять...

Судя по логу ускорение есть.
Использую SDL2 для вывода текстур.

Video SDL: driver = x11, w = 1280, h = 720, rate = 60, format = 24 bpp

Но функция SDL_CreateRenderer( window, -1, SDL_RENDERER_ACCELERATED );
Говорит что нет такого рендера, в итоге перехожу на софтовый

При запросе списка рендеров пишет:

Renderer: software software=1 accelerated=0, presentvsync=0 targettexture=1

Только софтовый(

Включен софтовый рендер. Чтобы всё заработало, надо принудительно отключить GLX в xorg.conf

К сожалению ничего не изменилось(

Где порыть?

Цитата

(EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied

Нет прав на устройство. Надо сделать правило в udev

После повторного запуска сообщение исчезает.
И это не причина. Проверил

Хорошо. Не получается(
Тогда есть ли варианты использование 2D или 3D ускорителя без завязки Х сервера.
SDL использует X11, но не видит ускоритель. Как быть...

Нужно менять масштаб текстур на лету, те задержки должны быть минимальны.
Я в тупике(

Пробую FFMPEG но там софтовый scale((

Грубо говоря есть исходная текстура 1920x60 надо превратить её в 1280x60.

SDL2 может работать без иксов с EGL/ES2, не уверен только поддерживает ли Mali - возможно надо немного инициализацию добавить

https://solarianprogrammer.com/2015/01/22/raspberry-pi-raspbian-getting-started-sdl-2/

Я там смотрел, к сожалению стандартная инициализация SDL под мали не подходит. Нарыл в исходниках мали пример как использовать EGL.

Маленький прорыв, посмотрим покрутим. Спасибо

Для i.mx6 (vivante) mastermind делал - можно на его примере добавить Mali

https://www.starterkit.ru/html/index.php?name=forum&op=view&id=25479#25480

Интересно. Люди вроде пилят драйвер под мали. Сейчас проверим.
