Linux support for ARM big.LITTLELinux support for ARM big.LITTLEPosted Feb 16, 2012 7:58 UTC (Thu) by dlang (✭ supporter ✭, #313)In reply to: Linux support for ARM big.LITTLE by fredrik Parent article: Linux support for ARM big.LITTLE
the linux kernel already has the ability to relax timing for wakeups so that they can be combined with other events.
as for scheduling different types of tasks on different cores, unless the slow core is not fast enough to keep up with the running application, there's no reason to use the fast core at all.
I can guarantee you that you cannot trust the application to tell you what it's needs really are, the only sane way is to watch the application and if it's trying to do more than the slow core can keep up with (with the other tasks that are also running), then and only then should you migrate it to a faster core.
