Explore the evolving intersection between DRM (Direct Rendering Manager) subsystem and cgroup memory management in this 30-minute conference talk from the Linux Plumbers Conference. Discover how traditional GPU memory management approaches are being challenged by the increasing deployment of GPUs in server and HPC environments, along with the rise of shared memory devices without dedicated device RAM. Learn about the technical challenges involved in integrating DRM with cgroup memory management systems, including backwards compatibility considerations and forward-looking design principles. Examine the shift from client-focused GPU usage patterns to more complex server scenarios that demand better integration with Linux kernel memory management frameworks. Gain insights into potential solutions for bridging these two critical subsystems while maintaining system stability and performance across diverse GPU deployment scenarios.
