[ Upstream commit feffe5b ] Commit 95158a8 ("sched,rt: Use the full cpumask for balancing") allows find_lock_lowest_rq() to pick a task with migration disabled. The purpose of the commit is to push the current running task on the CPU that has the migrate_disable() task away. Howeve...

sched,rt: disable rt_runtime borrowing by default Browse files Make the default RT_RUNTIME_SHARE setting reflect the most common throttle role, that of safety mechanism to protect the box. Bug 1269903 Change-Id: Id4ccf0095ea254f2e15fddc7ab02069f7f60a7c0 Signed-off-by: Mike Galbraith <...
Is it safe to set/proc/sys/kernel/sched_rt_runtime_usto-1? Resolution In short, settingsched_rt_runtime_usto-1can beextremely dangerous. A value of-1means no limit. In other words, a "run-away" real-time task will be permitted to monopolise a CPU which could (potentially) lock up...
