[LITMUS^RT] about installation of LITMUS-RT

[Xin Zhou]

Hi Tianyang,

Default configuration, generally might not boot the system.
Tries to remove redundant modules and only use exactly necessary driver, file system, etc.
Hope this would help.


regards,

Jeff Zhou

Dear all,

My name is Tianyang Che. I've encountered some difficulties during installing the litmus-rt. I was following the installation instruction provided by the litmus-rt website.

I've summarized my method below:

cd $DIR
# get Linux 3.0
wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.0.tar.bz2
tar xjf linux-3.0.tar.bz2
wget http://www.litmus-rt.org/releases/2012.3/litmus-rt-2012.3.patch
mv linux-3.0 litmus-rt
# apply the LITMUS RT patch
cd litmus-rt
patch -p1 < ../litmus-rt-2012.3.patch

#as for the configuration file, I just used the sample config which is provided in the website.
make menuconfig
# compile the kernel
make bzImage
make modules
make modules_install
make install
mkinitradfs -o initrd.img-3.0.0-litmus-litmus2012.2 3.0.0-litmus-litmus2012.2
update-grub


Then when I was trying to get into the new kernel, I always got this initial image.

I installed litmus-rt under kernel v3.0. And I used Ubuntu 12.04, both on virtual machine and real computer.


Hope to get help from you. Thank you very much.



Sincerely,
Tianyang.


Hi Tianyang,

Are you able to boot into the vanilla Linux 3.0 kernel without the Litmus patch applied?  We should probably figure out if the problem is with the Litmus patch or with the config file.  It is most likely the later, but we can try to rule out the Litmus patch as the cause.  The configuration file needs to be tailored to support your system's hardware.
