Description

Modern GPUs and modern graphics APIs leave less and less responsibilities to kernel GPU drivers, moving those to some firmware or to the usermode driver.

Throughout this presentation we will detail some of the aspects that make recently submitted DRM drivers different from what we had previously, and why things are structured like that. We will also give clues about what modern drivers should look like and the APIs that are being added or extended to facilitate their development, all of this being backed by some examples gathered from the two GPU drivers we were involved in:

  • Panthor (formerly known as PanCSF), which is adding support for the second iteration of Mali Valhall GPUs
  • PowerVR, which is adding support for Series 6XT and Series A Imagination GPUs
