Linux Kernel compilation and installation of RTAI

Linux Kernel can improve computer performance. The following describes how to compile the Linux kernel system.

1. Download the Linux Kernel

Ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.4.tar.bz2

2. download the latest RTAI Real-Time Linux Kernel

Https://www.rtai.org/RTAI/rtai-3.7.1.tar.bz2

3. Re-compile the Linux Kernel

#cd rtai-3.7.1      
  
  
#make menuconfig      
  
  
#make       
  
  
#make install      
  
  
#cd rtai-3.7.1    
  
  
#make menuconfig    
  
  
#make     
  
  
#make install     
 
 

After installing RTAI in Linux kernel, create an empty file and enter the following code:

#!/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  
 
 

Save the code as rt_script.

#chmod +x rt_script    
  
  
#./rt_script    
  
  
#chmod +x rt_script  
  
  
#./rt_script  
 
 

Save the following script as start_rt

#!/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
