Installation On Debian Kernel 2.6.10 And RTAI 3.2 On AMD K7

Prepare

• download RTAI 3.2
• download adeos-linux-2.6.10-i386-r12.patch from [ADEOS Patches]
• if your installed version of gcc is >=4.0 then make sure, gcc points to gcc-3.3 and g++ to g++-3.3

Install the kernel sources

 su - 
 apt-get install kernel-sources-2.6.10
 cd /usr/src
 tar xf kernel-source-2.6.10.tar.bz2
 ln -s kernel-sources-2.6.10 linux
 cd /usr/src/linux
 make menuconfig

Configure the Kernel

• Choose K6 Processor instead of K7 because of FPU bugs (fix: message "unexpected fpu trap" in the testsuite latency)
• Deselect Loadable Module versioning (fix: compile errors)
• Deselect Support for local APIC (fix: system not booting with adeos patch)

It is a good idea to test the kernel, before to begin with rtai. For alternative ways to build the kernel see Installation on Debian.

 make 
 make modules_install install
 mkinitrd -o /boot/initrd.img-2.6.10 2.6.10

• edit lilo.conf to boot the kernel
  • vga=ask (fix: no display booting the new kernel)

 lilo

• reboot

RTAI

 patch -p1 < ../rtai/adeos-linux-2.6.10-i386-r12.patch
 make menuconfig
 make 
 make modules_install install
 mkinitrd -o /boot/initrd.img-2.6.10 2.6.10
 reboot

Now it is time for rtai

 cd ../rtai
 make menuconfig

• installdir /
• not doc build, because only lots of warnings
• enable FPU
• scheduler for uniprocessor
• LXRT scheduler

 make 
 make install
