\nIn der Anfangsphase konzentrierte sich der Panfrost-Treiber haupts\u00e4chlich auf die Implementierung der Unterst\u00fctzung f\u00fcr Midgard-Chips, aber nun richtet sich die Aufmerksamkeit auch auf Bifrost-Chips, die in Bezug auf den Befehlsfluss den Midgard-Chips \u00e4hnlich sind, jedoch erhebliche Unterschiede in den Anweisungen zur Ausf\u00fchrung von Shaders und in den Schnittstellen zwischen Shaders und Befehlsfluss aufweisen.<\/p>\n

Die Entwickler haben eine erste Implementierung eines Shader-Compilers vorbereitet, der einen spezifischen internen Anweisungsbestand f\u00fcr die GPU Bifrost unterst\u00fctzt. Zuk\u00fcnftig ist geplant, den Compiler um die Unterst\u00fctzung erweiterter Anweisungen zu erweitern, die das Erstellen komplexerer Shaders erm\u00f6glichen. Die \u00c4nderungen wurden in die Codebasis von Mesa \u00fcbertragen und werden Teil des n\u00e4chsten bedeutenden Releases 20.1 sein.<\/p>\n

Der Panfrost-Treiber entwickelt sich auf Basis des Reverse Engineerings der Originaltreiber von ARM und ist f\u00fcr die Arbeit mit Chips auf Basis der Mikroarchitekturen Midgard (Mali-T6xx, Mali-T7xx, Mali-T8xx) und Bifrost (Mali G3x, G5x, G7x) ausgelegt. F\u00fcr die GPUs Mali 400\/450, die in vielen \u00e4lteren ARM-Architektur-Chips verwendet werden, wird ein separater Treiber entwickelt. Lima<\/a><\/noindex>.<\/p>\n
