Callsite Trampolines for Memory Allocation Profiling

Explore a conference talk from the Linux Plumbers Conference that delves into the concept of callsite trampolines. Learn about the need for compiler support in instrumenting call sites of specific functions, particularly for memory allocation profiling. Discover how this technique can store additional data for each call site, as revealed during the LSF/MM/BPF conference. Examine Steven Rostedt's presentation, which provides detailed insights into this idea. Gain valuable knowledge about the potential applications and implications of callsite trampolines in the context of Linux kernel development and performance optimization.
