Google has published a detailed explanation of how this will be achieved.<\/p>\n\n\n\n
Google's Android LLVM toolchain team has announced the introduction of a feature called Automatic Feedback-Directed Optimization (AutoFDO) into the Android kernel itself, which could bring a huge leap in system performance.<\/p>\n\n\n\n
AutoFDO, first introduced in Android 12 (2021), is a sampling-based optimization technique.<\/p>\n\n\n\n
It uses real-world execution data, collected directly from hardware monitors, to guide compiler decisions.<\/p>\n\n\n\n
In this way, static analysis is replaced with profiles that reflect the actual usage of the device.<\/p>\n\n\n\n
This feature is similar to the PGO (Profile Guided Optimization) technology already used in Windows and Linux, as well as in Google's Chromium-based applications.<\/p>\n\n\n\n
According to Google, this approach allows the compiler to more easily identify \"hot\" code paths - those that are executed most often - and optimize them accordingly.<\/p>\n\n\n\n
These profiles are created under controlled laboratory conditions by running representative workloads, including the 100 most popular applications.<\/p>\n\n\n\n
In its simplest terms, the principle is somewhat similar to how data caching works.<\/p>\n\n\n\n
Google states that their research shows an average performance increase of 10.5 percent.<\/p>\n\n\n\n
Considering that the Android kernel takes up about 40% of the total processor (CPU) time, the results are tangible: 4% faster cold launch of applications and 1% faster boot time.<\/p>\n\n\n\n
While these percentages don't seem huge on paper, Google claims that these optimizations are great for the overall user experience as they translate into faster switching between apps, a more fluid interface, and longer battery life.<\/p>\n\n\n\n
The feature is currently targeting kernel versions android16-6.12 and android15-6.6, and data was collected on Pixel devices. Google plans to expand support to newer versions of Generic Kernel Images (GKI) and other architectures beyond the current aarch64.<\/p>\n\n\n\n
By adopting a strategy that is \u201cconservative by default,\u201d Google points out that it is trying to ensure that AutoFDO increases speed without compromising the reliability of the system itself.<\/p>","protected":false},"excerpt":{"rendered":"
