Linux内核文件的查找和修改

使用的是ubuntu14.04系统，采用VMware虚拟机安装的。

从内核稍作修改的内容看起，联想到的，以后可能需要自己修改某些内核的代码来匹配硬件。

虚拟机的内核文件位置：/usr/src/linux-headers-4.2.0-27-generic/kernel/

现在使用的是海思3519和3516A的系统，用以做视频监控。

原文的连接如下：点击打开链接（3519下的内核稍作修改）

现在找找3516A开发板的内核位置，文件系统已经存在，但是打开文件系统是找不到内核的，内核文件在开发板给的资料中，

xxx@ubuntu14:~/project_Hi3519/linux-3.18.y/arch/arm/boot/dts$ 

内核文件就在改目录下，按照链接也能找到文件，但是具体内容不太一样。

不过想要以后查看内核的话文件都在这里。

链接中所说的文件内如下：
