We are pleased to announce the 2.6.24.7-rt17 tree, which can be downloaded from the location:
http://rt.et.redhat.com/download/
Information on the RT patch can be found at:
http://rt.wiki.kernel.org/index.php/Main_Page
This is a bugfix update:
- use the correct version of the ppc64 percpu patch pointed out by Chirag Jog
to build a 2.6.24.7-rt17 tree, the following patches should be applied:
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.tar.bz2 http://kernel.org/pub/linux/kernel/v2.6/patch-2.6.24.7.bz2 http://rt.et.redhat.com/download/patch-2.6.24.7-rt17.bz2
And like always, Steven's RT version of Matt Mackall's ketchup will get this for you nicely:
http://people.redhat.com/srostedt/rt/tools/ketchup-0.9.8-rt3
As usual the broken out patches are also available.
Thanks,
tglx
