El c\u00f3digo del controlador est\u00e1 escrito en Rust y consta de algo m\u00e1s de 600 l\u00edneas de c\u00f3digo. El desarrollo del controlador Tyr se lleva a cabo en colaboraci\u00f3n entre empleados de Collabora, Arm y Google.        <\/p>\n<p>Como base para crear el nuevo controlador, se utilizaron componentes del controlador abstracto rust_platform_driver y del controlador Nova, desarrollado para GPU NVIDIA, escrito en Rust y parcialmente incorporado en el n\u00facleo 6.15. La funcionalidad para interactuar con GPU Mali se ha portado desde el controlador DRM existente Panthor (Direct Rendering Manager), escrito en C. La uAPI del controlador Tyr es id\u00e9ntica a la uAPI del controlador Panthor, lo que permite utilizar componentes de espacio de usuario ya existentes.       <\/p>\n<p>La tecnolog\u00eda CSF, utilizada desde la d\u00e9cima generaci\u00f3n de GPU Mali, es notable por delegar algunas funciones del controlador al firmware y emplear un nuevo modelo de organizaci\u00f3n de tareas en la GPU. En la GPU con interfaz CSF, en lugar de un modelo basado en el env\u00edo de cadenas de trabajos, se utiliza un modelo basado en un flujo de comandos con programaci\u00f3n de la cola de flujo de comandos en el firmware. Para organizar el trabajo del planificador, la GPU incorpora un microcontrolador Cortex-M7, y se ha previsto una unidad especial para la ejecuci\u00f3n de comandos (Command Execution Unit) para llevar a cabo los instructivos de CSF.     <\/p>\n<p>La funcionalidad de Tyr a\u00fan est\u00e1 rezagada en comparaci\u00f3n con el controlador Panthor, pero los desarrolladores tienen la intenci\u00f3n de cerrar la brecha gradualmente hasta alcanzar la paridad en las capacidades de los controladores. Las funciones faltantes requieren la integraci\u00f3n de abstracciones adicionales en el n\u00facleo para la creaci\u00f3n de controladores en Rust; por lo tanto, el desarrollo del controlador Tyr se sincronizar\u00e1 con la adici\u00f3n de estas abstracciones en el n\u00facleo. Por ejemplo, actualmente no hay capacidades para mapear la memoria en controladores Rust para GPU, desarrolladas en un conjunto de parches GPUVM que a\u00fan no se ha aceptado.<br \/>\n<br \/>Fuente:
