Note that in this instance the shared region is the bus used to access the cache. Reserving a cache region won't help with that. One would have to reserve time slices on the bus.
- angry_octet 6y agoBut if the cache is in a different set, and each security partition has exclusive access to particular slices, you can't get contention because access is forbidden. Also, time slicing might not be sufficient due to the queues in each LLC slice. If you can fill the queue the bus access will retry I guess.
