Writing an open source GPU driver - without the hardware

January 27, 2022 by Alyssa Rosenzweig  |   Blog

Until now, no Valhall devices (Mali-G57, Mali-G78) ran mainline Linux - whilst this made driver development obviously difficult, there’s no better time to write drivers than before the devices even get into the hands of end users.
