上一篇我们讲了:内存泄漏系列专题分析之二十七:内存占用测试Camera相机进程内存指标分布report概述ok
这一篇我们开始讲: 内存泄漏系列专题分析之二十八:内存占用测试report结果过程计算方式和Camera进程各种内存指标dump方式
目录
一、问题背景
二、:report结果过程计算方式和Camera进程各种内存指标dump方式
2.1:Camera相机进程各种内存指标dump方式
2.2 :内存占用测试report结果过程计算方式
2.2.1 :单次测试内存值
2.2.2 :重复内存
2.2.2.1 Camera APP ION内存
2.2.2.2 Camera HAL ION内存
2.2.2.3 重复内存
2.2.3 :单次测试总内存
2.2.4 :内存占用最大值
2.2.5 :内存占用评判
内存指标非常之多,每个内存指标都可能存在内存占用超标。而每个内存指标又是如何dump出来的呢?上一篇我们讲了:内存泄漏系列专题分析之二十七:内存占用测试Camera相机进程内存指标分布report概述ok
这一篇我们讲里面涉及的内存指标获取方式进行专门讲解。
这部分和内存泄漏的方式一致,参考:内存泄漏系列专题分析之二十五:内存泄漏测试report Camera相机进程各种内存指标dump方式
每个指标读取方式,参考:内存泄漏系列专题分析之二十五:内存泄漏测试report Camera相机进程各种内存指标dump方式
这部分和内存泄漏有点类似,但也有点区别,内存占用测的内存峰值,因此dump时间点一般内存峰值附近dump,这块就需要添加埋点去dump了。

相机总内存 = 3个进程的PSS部分(非DMA)+ 3个进程ION/DMA部分(DMA) - ION重复数据 - 三个进程的Code
从50次或者100次里调休最大的一次总内存值,作为内存占用结果的最终值。
由于内存占用存在波动,因此测试机的内存占用值不超过对比机百分之多少即可。
