La conferin\u021ba XDC2020 (Conferin\u021ba dezvoltatorilor X.Org) anun\u021bat<\/a><\/noindex> despre aderarea companiei ARM la procesul de dezvoltare a proiectului Panfrost<\/a><\/noindex>, care dezvolt\u0103 un driver deschis pentru nucleele GPU Mali. Compania ARM a exprimat disponibilitatea<\/a><\/noindex> de a furniza dezvoltatorilor driverului informa\u021biile \u0219i documenta\u021bia necesare pentru o \u00een\u021belegere mai complet\u0103 a echipamentului \u0219i pentru a focusa aten\u021bia pe dezvoltare, f\u0103r\u0103 a pierde vremea descifr\u00e2nd enigme \u00een procesul de inginerie invers\u0103 a driverelor binare. Anterior, o situa\u021bie similar\u0103 a avut loc cu implicarea companiei Qualcomm \u00een proiectul Freedreno<\/a><\/noindex>, care dezvolt\u0103 un driver liber pentru GPU-ul Qualcomm Adreno.<\/p>\n

Participarea companiei ARM va ajuta la atingerea stabilit\u0103\u021bii implement\u0103rii necesare preg\u0103tirii pentru utilizarea pe scar\u0103 larg\u0103 \u0219i va asigura un suport mai complet pentru instruc\u021biunile interne specifice GPU-ului Mali, datorit\u0103 furniz\u0103rii de informa\u021bii de prim\u0103 m\u00e2n\u0103 despre arhitectura chipurilor. Accesibilitatea documenta\u021biei interne va permite, de asemenea, ob\u021binerea unei performan\u021be maxime, conformit\u0103\u021bii complete cu specifica\u021biile \u0219i acoperirea tuturor capabilit\u0103\u021bilor disponibile ale GPU-urilor Midgard \u0219i Bifrost.<\/p>\n

Primele modific\u0103ri, preg\u0103tite pe baza informa\u021biilor primite de la ARM, sunt deja au fost transmise<\/a><\/noindex> \u00een baza de cod a driverului. \u00cen particular,
\ns-au efectuat lucr\u0103ri pentru a aduce la standard opera\u021biile de ambalare a instruc\u021biunilor \u0219i a Republii dezasamblera, pentru a reflecta mai precis arhitectura setului de instruc\u021biuni GPU Bifrost \u0219i conformitatea cu terminologia acceptat\u0103 de ARM.<\/p>\n

Driverul Panfrost a fost fondat \u00een 2018 de Alyssa Rosenzweig, care lucreaz\u0103 la Collabora, \u0219i s-a dezvoltat p\u00e2n\u0103 acum pe baza ingineriei inverse a driverelor originale de la ARM. \u00cen prezent, driverul suport\u0103 func\u021bionarea cu chipuri bazate pe microarhitecturile Midgard (Mali-T6xx, Mali-T7xx, Mali-T8xx) \u0219i Bifrost (Mali G3x, G5x, G7x). Pentru GPU-urile Mali 400\/450, utilizate \u00een multe chipuri vechi bazate pe arhitectura ARM, se dezvolt\u0103 separat un driver Lima<\/a><\/noindex>. <\/p>\n
