Any reference material you know of achieving this? I don't think there's any way (currently) to accomplish this.
The scheduler only works with processes that exist. There's no notion that I'm aware of to "pre-schedule" a process, before any of the kernel data structures for it exist. Sorry, but I came into the middle of the discussion. What are you actually trying to accomplish? Do you want some historical information about the process, or about systemwide scheduling to be present at the time the process eventually gets started? Is the process starting too slowly? Are you trying to adjust the priority of other processes, as if the non-existent one were already present in the system? Maybe what you need, instead of a placeholder for a non-existent process, is just a tweak to the scheduler algorithms to create the desired scheduling effect once the process comes into existence. It really doesn't make sense to make the scheduler aware of a process that doesn't exist. IMHO, you need to think of a different way to attack whatever problem you're trying to address. -- Tim ============================= Tim Bird Architecture Group Chair, CE Workgroup of the Linux Foundation Senior Staff Engineer, Sony Network Entertainment ============================= -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
