Abstract
Disclosed is a cache locking system that includes a cache controller that is operable to receive a first request from a device to lock a first way in the cache. The cache controller is operable to determine that the first way in the cache is not lockable by the device. The cache controller is also operable to send, to the device, a rejection of the first request. The cache controller is further operable to receive a second request from the device to lock a second way in the cache. The cache controller is operable to lock the second way in the cache in response to the second request.
