Abstract:
A method includes receiving, by a memory management unit (MMU) comprising a translation lookaside buffer (TLB) and a configuration register, a request from a processor core to directly modify an entry in the TLB. The method also includes, responsive to the configuration register having a first value, operating the MMU in a software-managed mode by modifying the entry in the TLB according to the request. The method further includes, responsive to the configuration register having a second value, operating the MMU in a hardware-managed mode by denying the request.
