Hello all,
My ex-collegues at Alcatel are screaming for help. They want to run
an app (as root, debatable but that's another story) using SCHED_FIFO
threads on an openSuSE 11.4 system.
Using the 'default' kernel (which has CONFIG_PREEMPT not set), this
works. Using the 'desktop' kernel (CONFIG_PREEMPT=y) they get an
EPERM when trying to start a RT thread, even as root.
As I haven't used SuSE for ages, has anyone an idea of what is
happening here ?
TIA,
god's way of telling them oS 11.4 has just been deprecated and will not
receive further mainline support? :)
i'm not sure 11.4 had cgroups enabled already, but if so, then robin is
probably right on the mark.
