Notes

Abstract

A couple years ago, Alyssa Rosenzweig developed a compute-based geometry and tessellation shader implementation for the Asahi (OpenGL) and Honeykrisp (Vulkan) drivers. Since then, the core of this implementation has been extracted into a common library within Mesa called libpoly. In this talk, Faith will talk about the changes needed to libpoly as well as panvk in order to integrate libpoly into panvk for geometry shader support on Mali GPUs.

Speakers

Faith Ekstrand

Faith has been contributing to the Mesa 3D graphics library for over a decade and is one of the core maintainers. She developed the NIR optimizing compiler layer, the Intel Vulkan driver (ANV), most of the shared Vulkan runtime, and the new Vulkan driver for NVIDIA hardware (NVK). She's also made other contributions scattered all over the Linux graphics stack from various other Mesa drivers to the kernel/DRM to X11 to the Wayland protocol and Weston. She also sits on the Vulkan and SPIR-V spec committees, representing Linux graphics. She started her professional work on Linux graphics at Intel but now works at Collabora where she continues that work with a more vendor-neutral perspective.
