Push the trade-off between fluency and power saving even further via QTI Boost Framework
The previous Project WIPE, automatically adjust the
interactiveparameters via simulation and heuristic optimization algorithms, and working on all mainstream devices which use
interactiveas default governor. The recent WIPE v2, improved simulation supports more features of the kernel and focuses on rendering performance requirements, automatically adjusting the
input boostparameters. However, after the EAS is merged into the mainline, the simulation difficulty of auto-tuning depends on raise. It is difficult to simulate the logic of the EAS scheduler. In addition, EAS is designed to avoid parameterization at the beginning of design, so for example, the adjustment of schedutil has no obvious effect.
WIPE v2 focuses on meeting performance requirements when interacting with APP, while reducing non-interactive lag weights, pushing the trade-off between fluency and power saving even further.
QTI Boost Framework, which must be disabled before applying optimization, is able to dynamically override parameters based on perf hint. This project utilizes
QTI Boost Frameworkand extends the ability of override custom parameters. When launching APPs or scrolling the screen, applying more aggressive parameters to improve response at an acceptable power penalty. When there is no interaction, use conservative parameters, use small core clusters as much as possible, and run at a higher energy efficiency OPP under heavy load.
