提前准备好 linux 内核源代码,假设是 x86 系统.能够去下载原生内核(Vanilla kernel): wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.18.17.tar.gz 假设是arm系统,或者其它系统,则下载厂商定制过的内核源代码. 假设有须要.patch内核.如 preempt-rt 补丁:(注意补丁版本号必须与内核版本号相应,此处均为 3.18.17 版本号.假设是定制过的内核.则必须找到相应定制过的补丁.)…

How can I output my target message when I using dotnet build in command line. I use command line to create a web api application. dotnet new webapi -o Lindexi Then I edit the Lindexi\Lindexi.csproj and add the message. <Target Name="Lindexi"…

现在CPU2核以上比较普遍了,平时用linux上上网可能用不着双核甚至4核,大部分发行版内核都启用了CPU_HOTPLUG,到/sys/devices/system/cpu下可以看到文件夹cpu0.cpu1,除cpu0(这个不能关)每个文件夹下都有一个online文件,往里面写0就可以关闭核心,比如我的T7300,echo '0' >/sys/devices/system/cpu/cpu1/online 就可以关闭第二个核,不影响小型应用.要开启,往里面echo 1就行.这个操作好像要root完…

前言 之前对uboot的构建进行了分析,现在再对linux kernel的构建进行分析.几年前的确也分析过,但是只是停留在笔记层面,没有转为文章,这次下定决定来完善它. 环境 同样,采用的还是zynq平台的linux,从Makefile可以看到版本: VERSION = 3 PATCHLEVEL = 15 SUBLEVEL = 0 EXTRAVERSION = NAME = Shuffling Zombie Juror linux Makefile支持的选项(最常用到的) 选项V,用于开启或者关…
