Isolating GPU access in its own process
Chromium's process architecture has graphics access restricted to a separate GPU-process. There are several reasons why this could make sense, three common ones are: Security, Robustness and Dependency Separation.
GPU access restricted to a single process requires an efficient framework for communication over IPC from the other processes, and most likely a framework for composition of surfaces. This talk describes both the possible motivations for this kind of architecture and Chromium's solution for the IPC framework. We will demonstrate how a multiprocess program can compose into a single window on Linux.

She has previously worked at Opera Software on their Desktop Browser and at Cisco on their Telepresence Hardware Endpoints, primarily on Linux. Patricia is a curious person, always trying to find out how things work. She hopes that we will find a way to make the world a better place by creating things that can be used for good.
