Esta tecnolog\u00eda desplaza algunas funciones del controlador a la firma para reducir la carga en la CPU y ofrece un nuevo modelo para la organizaci\u00f3n de la ejecuci\u00f3n de tareas en la GPU. El controlador DRM (Direct Rendering Manager) panthor ha sido aceptado en la rama drm-misc y se espera que forme parte del n\u00facleo Linux 6.10. Los cambios necesarios para dar soporte al nuevo controlador tambi\u00e9n han sido aceptados en Mesa y se han incluido en el controlador Gallium panfrost para GPUs Mali.       <\/p>\n<p>En la nueva generaci\u00f3n de GPU Mali, el programador Job Manager ha sido sustituido por la interfaz CSF (Command Stream Frontend), que, en lugar de un modelo basado en la cadena de trabajos, utiliza un modelo basado en un flujo de comandos con planificaci\u00f3n de la cola de flujo de comandos en la firma. Para gestionar el trabajo del programador en la GPU, se ha integrado un microcontrolador Cortex-M7, y se ha previsto una unidad especial de ejecuci\u00f3n de comandos (Command Execution Unit) para la ejecuci\u00f3n de las instrucciones CSF. Estas caracter\u00edsticas requieren una organizaci\u00f3n fundamentalmente diferente para la transmisi\u00f3n de trabajos a la GPU desde el espacio del usuario.     <\/p>\n<p>Inicialmente, se hab\u00eda intentado implementar el soporte para la GPU Mali en base a CSF en el controlador DRM Panfrost, pero los desarrolladores concluyeron que esto complicar\u00eda mucho el controlador existente y ser\u00eda m\u00e1s \u00f3ptimo crear un nuevo controlador para CSF utilizando una arquitectura diferente. En el controlador panthor se ha implementado una nueva uAPI, una nueva l\u00f3gica de planificaci\u00f3n de trabajos y una nueva l\u00f3gica de gesti\u00f3n de MMU\/GPU-VA. Como base para el nuevo controlador, se ha utilizado el c\u00f3digo existente del controlador DRM Panfrost, del cual se han tomado plantillas est\u00e1ndar para la inicializaci\u00f3n del controlador, gesti\u00f3n de frecuencias y gesti\u00f3n de energ\u00eda.    <\/p>\n<p>Al principio, el desarrollo del nuevo controlador se llev\u00f3 a cabo utilizando ingenier\u00eda inversa, pero luego la empresa ARM se uni\u00f3 al proyecto, proporcion\u00f3 acceso a la documentaci\u00f3n y particip\u00f3 en la revisi\u00f3n del c\u00f3digo. Dos empleados de ARM obtuvieron el estatus de co-mantenedores del controlador para el n\u00facleo Linux. M\u00e1s adelante, tras la disponibilidad del controlador OpenGL, el trabajo se centrar\u00e1 en la implementaci\u00f3n del controlador Vulkan para las nuevas GPU Mali y la modernizaci\u00f3n del controlador Vulkan existente para las viejas GPU Mali.      <\/p>\n<p>Se se\u00f1ala que el controlador panthor preparado permite el soporte de GPU en placas con SoC Rockchip RK3588. La empresa Collabora tambi\u00e9n ha trabajado para garantizar la carga de placas basadas en Rockchip RK3588 utilizando un stack de software completamente abierto. Se ha preparado una imagen del sistema basada en Debian y un cargador de arranque abierto para reemplazar los componentes propietarios BL31 (Boot Loader stage 3.1).<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=60728\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Collabora \u043e\u0431\u044a\u044f\u0432\u0438\u043b\u0430 \u043e \u0433\u043e\u0442\u043e\u0432\u043d\u043e\u0441\u0442\u0438 \u043e\u0442\u043a\u0440\u044b\u0442\u043e\u0433\u043e \u0434\u0440\u0430\u0439\u0432\u0435\u0440\u0430 panthor, \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u0435\u043c\u043e\u0433\u043e \u0434\u043b\u044f \u0434\u0435\u0441\u044f\u0442\u043e\u0433\u043e \u043f\u043e\u043a\u043e\u043b\u0435\u043d\u0438\u044f GPU Mali (G310, G510, G710), \u0432 \u043a\u043e\u0442\u043e\u0440\u043e\u043c \u043f\u0440\u0438\u043c\u0435\u043d\u044f\u0435\u0442\u0441\u044f \u0442\u0435\u0445\u043d\u043e\u043b\u043e\u0433\u0438\u044f CSF (\u0421ommand Stream Frontend), \u0432\u044b\u043d\u043e\u0441\u044f\u0449\u0430\u044f \u043d\u0430 \u0441\u0442\u043e\u0440\u043e\u043d\u0443 \u043f\u0440\u043e\u0448\u0438\u0432\u043a\u0438 \u043d\u0435\u043a\u043e\u0442\u043e\u0440\u044b\u0435 \u0444\u0443\u043d\u043a\u0446\u0438\u0438 \u0434\u0440\u0430\u0439\u0432\u0435\u0440\u0430 \u0434\u043b\u044f \u0441\u043d\u0438\u0436\u0435\u043d\u0438\u044f \u043d\u0430\u0433\u0440\u0443\u0437\u043a\u0438 \u043d\u0430 CPU \u0438 \u043f\u0440\u0435\u0434\u043b\u0430\u0433\u0430\u044e\u0449\u0430\u044f \u043d\u043e\u0432\u0443\u044e \u043c\u043e\u0434\u0435\u043b\u044c \u043e\u0440\u0433\u0430\u043d\u0438\u0437\u0430\u0446\u0438\u0438 \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u044f \u0440\u0430\u0431\u043e\u0442 \u043d\u0430 GPU.
