Arm engineer Karunika Choo today sent out the latest patches developing a new GPU-specific initialization framework for the Panthor open-source kernel graphics driver as part of bringing up support for newer Mali GPUs.
The initial focus of this new framework for the Panthor Direct Rendering Manager (DRM) driver is for extending support to some newer Mali GPU families than what is otherwise supported. The current patches extend the Panthor driver to supporting the Mali-G310, Mali-G510, Mali-G710, Mali-G715, Mali-G720, and Mali-G725 series of GPUs.
These patches provide support for the 5th Gen Mali architecture introduced over 2023 and 2024 with the G720 and G725 but stops short of supporting the very latest Immortal G925 GPU. The Mali G310 / G510 / G710 / G715 GPUs are of their older Valhall architecture.
Besides these particular GPUs being enabled by the patches, this framework will hopefully make it easier to onboard future Mali architectures within the Panthor driver by better coping with device/generation-specific initialization differences.
More details on these latest patches for the upstream Panthor open-source Mali kernel graphics driver via this dri-devel series.
