Abstract:
Hardware accelerator memory address translation fault resolution is provided. A hardware accelerator and a switchboard are in communication with a processing core. The hardware accelerator determines at least one memory address translation related to an operation having a fault. The switchboard forwards the operation with the fault memory address translation from the hardware accelerator to a second buffer. The operation and the fault memory address translation are flushed from the hardware accelerator, and the operating system repairs the fault memory address translation. The switchboard forwards the operation with the repaired memory address translation from the second buffer to a first buffer and the hardware accelerator executes the operation with the repaired address.
