io_uring for Direct Rendering Manager (DRM) - Exploring Asynchronous Job Submissions

Explore a technical conference talk from XDC 2024 examining the potential implementation of io_uring mechanisms in the Direct Rendering Manager (DRM) framework. Learn about the challenges and opportunities of modern GPU architectures shifting functionality to firmware for direct userspace job submissions. Understand how io_uring's asynchronous request queuing from userspace could benefit DRM by reducing context switching overhead while maintaining kernel driver control. Delve into critical considerations including security concerns, particularly Android's complete disablement of io_uring, implications for userspace job scheduling, and the role of GPU firmware in job management. Examine the technical tradeoffs and gather community feedback on integrating io_uring capabilities within the DRM framework.
