一、背景

二、：process_capture_request四级日志如下

三、：process_capture_request四级日志分析详解

四、：process_capture_request四级日志关键字

五、：总结

一、背景

1：【效率决定成长空间】无论什么开发，分析日志是解决问题的法宝。且是最有效最常用的调试工具，特别是在Android或Linux领域下，log分析是开发必备技能，然而log分析效率参差不齐，你分析一份日志要一天，别人分析只需要一个小时，作何感想？别人一年的学习成果可能是你几年才能学会。

2：【巨量日志降低了开发效率】接触过Android日志，就清楚日志量非常大。几十个进程几百个线程同时并行打印日志。而Camera领域日志量极大，因为预览一般是每秒30帧的日志量，录屏一般是每秒60帧的日志量，少则几万行日志，多则几十万行日志，更多则多个日志总量几百万行日志。

3：【日志梯度分级来提效】开发追求效率，如何快速有效挖掘出问题，并如何解决问题变得尤为重要。此专题将以梯度分级日志来分析日志，让日志流程变得简单化，提高解决问题的效率。

4：【举一反三】当前以高通CamX架构为例讲解Camera日志，方式通用，其他领域模块均可效仿借鉴。

5：【开发思维决定成长高度】当前讲述的是Camera领域log分析梯度分级讲解，讲究的是一种分析技巧，分析思维，一种感悟。技术路线的提升空间，需要更多开发技巧和开发学习能力去提升。技术大拿分析问题，可以从日志快速定位问题并解决问题，有充分的时间去学习更多知识，成长速度极快。同一起跑线，学习能力，开发效率等等都决定了程序员的成长提升空间。记得我毕业三年，同学之间的差距无限拉大，一些人还在几千块薪水，你已经是他的四五倍了，人与人的差距就是短短几年就拉开了。

二、：process_capture_request四级日志如下

PS：搜索类似【Start proc】中括号【 就有颜色体现了。

这里添加了【 关键字，过滤的是核心简化的核心流程日志过程，更加直观调用整个流程。

四、：process_capture_request四级日志关键字

PopulateFrameworkRequestBuffer|FillTuningModeData|UpdateFeatureModeIndex|PopulateHALToChiStreamBuffer|GetOutputBufferFromRDIQueue|ChiBufferManagerGetImageBuffer|SetRequestToFeatureMapping|SetupRequestOutputPortFence

五、：总结

当前日志主要涉及request过程：

  1. 当前日志重要性一般。
  2. 由于node与node之间的处理，无非就是buffer的输入输出，也就是数据流的传递，并进行二次处理，所有经常拿buffer指针传递。
  3. 之前有讲pipeline的拓扑图，node与node之间的port和link关系错综复杂。这里需要SetupRequestOutputPortFence设置request对应node的outport fence来处理。
