Explore upcoming enhancements to Linux kernel memory allocation profiling infrastructure in this 16-minute conference talk from the Linux Plumbers Conference. Learn about the low-overhead mechanism that makes all kernel allocations visible for monitoring memory usage, tracking hotspots, detecting leaks, and identifying performance regressions. Discover proposed new features including NUMA awareness for better multi-node system support, MEMCG awareness for memory control group integration, context capture capabilities that were part of the original RFC, and IOCTL mechanisms for efficient data querying and filtering. Examine plans for reporting additional data such as gfp_flags and unaccounted memory sizes, along with userspace tooling developments for grouping allocations by categories and issuing ioctl commands. Gain insights into the prioritization process for these features based on community interest, understand the main implementation challenges and available options for each enhancement, and review performance data associated with some of these proposed improvements to the memory allocation profiling system.
