Hello Peterz, tglx I have some questions about migrate_disabe/enable(), in the past migrate_disabe/enable() is replaced by preempt_disable/enable() in no RT system.
And now migrate_disabe/enable() has its own implementation, I want to know in migrate_disabe/enable() critical area is blocking allowed? If allowed, There's a blockage in migrate_disabe/enable() critical area, and this time if CPU going offline，offline time will be longer. Is this normal phenomenon？ Thanks Qiang
