查看 RK3576 平台上 RKRGA 硬件加速引擎的运行状态、负载情况及当前占用它的进程,输出信息是内核通过 debugfs调试文件系统提供的调试数据方便定位图像 / 视频处理相关的性能问题。
RKRGA 是 Rockchip Raster Graphic Accelerator瑞芯微光栅图形加速器的缩写是 RK 芯片内置的硬件加速模块,专门负责高效处理图像 / 视频的缩放、旋转、格式转换、叠加等操作(比如 AI 视觉应用中的图像预处理、视频播放的画面缩放),能减轻 CPU/GPU 负担,提升处理效率。
/sys/kernel/debug/rkrga/load 是内核为 RKRGA 提供的 调试接口文件,通过读取它可以获取 RKRGA 的实时运行状态。
