Abstract:
In one embodiment, a method is contemplated. Access to a hardware accelerator is requested by a user-privileged thread. Access to the hardware accelerator is granted to the user-privileged thread by a higher-privileged thread responsive to the requesting. One or more commands are communicated to the hardware accelerator by the user-privileged thread without intervention by higher-privileged threads and responsive to the grant of access. The one or more commands cause the hardware accelerator to perform one or more tasks. Computer readable media comprises instructions which, when executed, implement portions of the method are also contemplated in various embodiments, as is a hardware accelerator and a processor coupled to the hardware accelerator.
