Description:
Rong Xu and
Han Shen described the kernel-optimization techniques that Google uses in the toolchains
track at the 2024 Linux
Plumbers Conference .
They talked about automatic
feedback-directed optimization (AutoFDO), which can be used with the
Propeller optimizer to produce kernels with better performance using profile information gathered from real workloads. There is a fair amount of
overlap between these tools and the BOLT post-link optimizer, which was the subject of a talk that directly preceded this session.
