Linux内核能提高计算机的使用性能。下面就这就来讲术Linux内核系统编译。
1、下载Linux内核
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.4.tar.bz2
2、下载***RTAI实时Linux内核
https://www.rtai.org/RTAI/rtai-3.7.1.tar.bz2
3、重新编译Linux内核
- view plaincopy to clipboardprint?
- $su
- #cp linux-2.6.29.4.tar.bz2 rtai-3.7.1.tar.bz2 /usr/src
- #tar jxvf linux-2.6.29.4.tar.bz2
- #tar jxvf rtai-3.7.1.tar.bz2
- #cd linux-2.6.29.4.tar.bz2
- #patch -p1 -b < ../rtai-3.7.1/base/arch/x86/patches/hal-linux-2.6.29.4-x86-2.4-01.patch
- #cp /boot/config-2.6.27.5-117.fc10.i686 ./.config
- #make menuconfig
- #make
- #make modules_install install
- $su
- #cp linux-2.6.29.4.tar.bz2 rtai-3.7.1.tar.bz2 /usr/src
- #tar jxvf linux-2.6.29.4.tar.bz2
- #tar jxvf rtai-3.7.1.tar.bz2
- #cd linux-2.6.29.4.tar.bz2
- #patch -p1 -b < ../rtai-3.7.1/base/arch/x86/patches/hal-linux-2.6.29.4-x86-2.4-01.patch
- #cp /boot/config-2.6.27.5-117.fc10.i686 ./.config
- #make menuconfig
- #make
- #make modules_install install
[注]在‘make menuconfig’这一步中的配置如下：
4、编译安装RTAI
- view plaincopy to clipboardprint?
- #cd rtai-3.7.1
- #make menuconfig
- #make
- #make install
- #cd rtai-3.7.1
- #make menuconfig
- #make
- #make install
Linux内核安装RTAI完成后，新建一个空文件，输入以下代码
- view plaincopy to clipboardprint?
- #!/bin/bash
- mkdir /dev/rtf
- for n in `seq 0 9`
- do
- f=/dev/rtf/$n
- mknod -m 666 $f c 150 $n
- done
- #!/bin/bash
- mkdir /dev/rtf
- for n in `seq 0 9`
- do
- f=/dev/rtf/$n
- mknod -m 666 $f c 150 $n
- done
将代码保存为rt_script.
- view plaincopy to clipboardprint?
- #chmod +x rt_script
- #./rt_script
- #chmod +x rt_script
- #./rt_script
将下面脚本保存为start_rt
- view plaincopy to clipboardprint?
- #!/bin/bash
- mknod -m 666 /dev/rtai_shm c 10 254
- for n in `seq 0 9`
- do
- f=/dev/rtf$n
- mknod -m 666 $f c 150 $n
- done
- #!/bin/bash
- mknod -m 666 /dev/rtai_shm c 10 254
- for n in `seq 0 9`
- do
- f=/dev/rtf$n
- mknod -m 666 $f c 150 $n
- done
然后存放在/etc/init.d/目录下view plaincopy to clipboardprint?
