Hello,
I am working on a zedboard and trying to use preempt-rt patch.
The working kernel (Linux zedboard
3.6.0-digilent-13.01-00002-g06b3889-dirty #4 SMP PREEMPT Sun Oct 6 12:23:48
MDT 2013 armv7l GNU/Linux) that I have is from a repository maintain by
digilent
git remote show origin
* remote origin
  Fetch URL: https://github.com/Digilent/linux-digilent.git
I assuming the main changes are in the area of arch/arm/boot/dts
I did a "git clone git://
git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git" and
downloaded the patch-3.6.11.1-2

I have tried the following
git checkout -b v3.6.11.1-2
which branch or tag actually goes to this new branch
git apply --stat ~/Downloads/patch-3.6.11.1-2 this seems to work
git apply --check ~/Downloads/patch-3.6.11.1-2 This shows lots of errors.

What would be the steps to take the changes in the linux-digilent
repository and the changes for linux-steps-rt to create my repository for
testing?

I am interested in testing performance with and without the patch.

For Real Time systems is this the best approach?
Any and all help will be welcomed.
Thanks
