En la conferencia XDC2020 (Conferencia de Desarrolladores de X.Org) que<\/a><\/noindex> se anunci\u00f3 la incorporaci\u00f3n de la empresa ARM al proceso de desarrollo del proyecto Panfrost<\/a><\/noindex>, que desarrolla un controlador abierto para las unidades de procesamiento gr\u00e1fico Mali. La empresa ARM ha expresado su disposici\u00f3n<\/a><\/noindex> para proporcionar a los desarrolladores del controlador la informaci\u00f3n y la documentaci\u00f3n necesarias para una comprensi\u00f3n m\u00e1s completa del hardware y enfocar su atenci\u00f3n en el desarrollo, sin perder tiempo desentra\u00f1ando enigmas en el proceso de ingenier\u00eda inversa de los controladores binarios. Anteriormente, algo similar ocurri\u00f3 con la incorporaci\u00f3n de la empresa Qualcomm al trabajo en el proyecto Freedreno<\/a><\/noindex>, que desarrolla un controlador libre para la GPU Qualcomm Adreno.<\/p>\n

La participaci\u00f3n de la empresa ARM ayudar\u00e1 a alcanzar la estabilidad de la implementaci\u00f3n hasta estar lista para el uso generalizado y proporcionar\u00e1 un soporte m\u00e1s completo para las instrucciones internas espec\u00edficas de la GPU Mali a trav\u00e9s de la informaci\u00f3n sobre la arquitectura de los chips de primera mano. La disponibilidad de documentaci\u00f3n interna tambi\u00e9n permitir\u00e1 lograr el m\u00e1ximo rendimiento, el pleno cumplimiento de las especificaciones y la cobertura de todas las capacidades disponibles de las GPU Midgard y Bifrost.<\/p>\n

Los primeros cambios, preparados sobre la base de la informaci\u00f3n obtenida de ARM, ya transferidas<\/a><\/noindex> se han integrado en la base de c\u00f3digo del controlador. En particular,
\nse ha trabajado en la normalizaci\u00f3n de las operaciones de empaquetado de instrucciones y en una reestructuraci\u00f3n completa del desensamblador, para reflejar con mayor precisi\u00f3n la arquitectura del conjunto de instrucciones de la GPU Bifrost y cumplir con la terminolog\u00eda aceptada en ARM.<\/p>\n

El controlador Panfrost fue fundado en 2018 por Alyssa Rosenzweig, que trabaja en la empresa Collabora, y ha sido desarrollado hasta ahora con base en la ingenier\u00eda inversa de los controladores originales de ARM. Actualmente, el controlador soporta los chips basados en las microarquitecturas Midgard (Mali-T6xx, Mali-T7xx, Mali-T8xx) y Bifrost (Mali G3x, G5x, G7x). Para las GPU Mali 400\/450, utilizadas en muchos chips antiguos con arquitectura ARM, se est\u00e1 desarrollando un controlador por separado. Lima<\/a><\/noindex>. <\/p>\n
