Hi. I am trying the Sched_deadline patch.
I am getting an error compiling:
kernel/sched/dl.c: In function ‘dl_runtime_exceeded’:
kernel/sched/dl.c:551:7: warning: unused variable ‘damount’

Peace Be With You.
Actually, I just got the Ericsson branch to compile.
Peace Be With You.
How does the modified schedtool work? There is no updated documentation.
http://gitorious.org/sched_deadline/schedtool-dl/commits/latest/2.6.36-dl-V3
If anyone could give an example of a 1000uS period / 500uS time, with
schedtool, or any other relevant information.
Most examples online use parameters that are no longer supported.
Peace Be With You.

Nobody knows? This is really obscure for an EDF patch. Making things a bit
more accessible should be a priority. I think a lot of enthusiasts would
like to have smooth control over stuff, without windows-jitter. If you can
do a robot arm, jitter-free with this, then I am very interested.
