Dear RT Folks,
After successfully patching a 3.2 kernel (gumstix platform) with
patch-3.2-rt10, I obtained the rt-tests suite from
git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-tests.git
I enabled CONFIG_PREEMPT_RT in menuconfig and disabled "CPU frequency scaling".
Compilation of rt-tests ("make all") on the platform is also successful.
When trying to execute cyclictest, the program reports: "Unable to
change scheduling policy! either run as root or join realtime group"
Looking in rt-utils.c, it appears that set_scheduler is unable to
select SCHED_FIFO scheduling policy.
Do you have any hints on how to fix this problem, or at least narrow
it down further? Could it
Best Regards,
Hartmut Behrens
