wince下查看驱动启动加载时间：celog

最近开始负责wince kernel部分了，现在项目也比较多。不过现在做完一个项目的kernel部分的驱动，现在压力轻了许多，其他两个项目的kernel部分的code，改起来也就比较容易了。呵呵。

     系统启动时间短，对于产品的来说，是一个重要的地方。想办法，降低各个drivers的启动加载时间，是我们的做底层driver的一个重要的工作要点吧。

    首先，我们要降低derivers的启动加载时间，那我们首先要知道一个项目里的，各个drivers的启动时间的具体情况。查看wince的drivers的各个drivers的加载时间，我用的是celog 工具。

  

   celog的工具的使用（我这几天看帮助文档所学的点皮毛，记录一下，以免自己以后忘记）

      1：打开所在项目的bsp，-----》project-----》properties--》configuration Properties ---->Build Options

           选中1》Enalbe event tracking during boot （IMGCELOGENABLE=1)

                 2》Flush tracked events to release directory(IMGAUTOFLUSH=1)

      2.根据帮助文档上的说明和自己的需要，修改注册表

         /WINCE600/PLATFORM/项目/FILES/platform.reg 如下

         

          IF IMGCELOGENABLE
[HKEY_LOCAL_MACHINE/System/CeLog]
    "Transport"="LocalFile"
    "FileName"="celog.clg"
    "FlushTimeout"=dword:7D
    "ZoneCE"=dword:00010000;CELZONE_DEBUG|CELZONE_BOOT_TIME|CELZONE_LOADER
    "BufferSize"=dword:00100000
    "ThreadPriority"=dword:0
    ;for more information please check CeLog Zones from microsoft help document.
ENDIF IMGCELOGENABLE

  3.重新sysgen和build bsp

 4 .分析celog）

   可以只适用如下的命令：

     进入项目的命令行编译环境（build----->open release directory in window )

      readlog -d -x celog.clg celog.text 或者readlog -x celog.clg celog.text （我是将deviece上获得的celog.cfg拷贝到release 目录的）

   

       分析后结果如下：readlog -x celog.clg celog.text 命令

   celog.text的部分内容如下：

两个驱动之间的时间差就是，驱动的启动加载时间。

你也可以用readlog -d -x celog.clg celog.text ，之间输出经过计算各个drivers启动时间差的celog
