P\u00e5 konferencen XDC2020 (X.Org Developers Conference) tilkendegivet<\/a><\/noindex> om virksomhederne ARMs deltagelse i udviklingen af projektet Panfrost<\/a><\/noindex>, der udvikler en \u00e5ben driver til Mali GPU'er. Virksomheden ARM har udtrykt vilje<\/a><\/noindex> til at give driverudviklerne de n\u00f8dvendige informationer og dokumentation for en bedre forst\u00e5else af hardwaren og fokusere opm\u00e6rksomheden p\u00e5 udviklingen, uden at spilde tid p\u00e5 at finde svar under reverse engineering af bin\u00e6re drivere. Tidligere skete det samme med Qualcomm, da de sluttede sig til arbejdet p\u00e5 projektet Freedreno<\/a><\/noindex>, der udvikler en fri driver til Qualcomm Adreno GPU'er.<\/p>\n

ARM's deltagelse vil hj\u00e6lpe med at stabilisere implementeringen til at v\u00e6re klar til udbredt brug og sikre en mere omfattende support til Mali GPU's specifikke interne instruktioner ved at give information om chiparkitekturen fra f\u00f8rste h\u00e5nd. Tilg\u00e6ngeligheden af intern dokumentation vil ogs\u00e5 muligg\u00f8re maksimal ydeevne, fuld overensstemmelse med specifikationerne og d\u00e6kning af alle tilg\u00e6ngelige funktioner i Midgard og Bifrost GPU'er.<\/p>\n

De f\u00f8rste \u00e6ndringer, der er forberedt p\u00e5 baggrund af oplysningerne fra ARM, er allerede blevet sendt<\/a><\/noindex> blevet integreret i driverens kodebase. Is\u00e6r
\ner arbejdet udf\u00f8rt for at bringe pakkeoperationernes kanoniske form og fullst\u00e6ndig redesigne disassembleren for mere pr\u00e6cist at afspejle Bifrost GPU's instruktionss\u00e6tsarkitektur og overensstemmelse med terminologien anvendt af ARM.<\/p>\n

Panfrost driveren blev grundlagt i 2018 af Alyssa Rosenzweig, der arbejder i Collabora, og har siden da udviklet sig baseret p\u00e5 reverse engineering af de originale drivere fra ARM. I \u00f8jeblikket underst\u00f8tter driveren chips baseret p\u00e5 mikroarkitekturerne Midgard (Mali-T6xx, Mali-T7xx, Mali-T8xx) og Bifrost (Mali G3x, G5x, G7x). Der udvikles en separat driver til GPU'er Mali 400\/450, der anvendes i mange \u00e6ldre chips baseret p\u00e5 ARM arkitekturen. Lima<\/a><\/noindex>. <\/p>\n
