  • Patent number: 11436013
    Abstract: A method of checking for a stall condition in a processor is disclosed, the method including inserting an inline instruction sequence into a thread, the inline instruction sequence configured to read the result from a timing register during processing of a first instruction and store the result in a first general purpose register, wherein the timing register functions as a timer for the processor; and read the results from the timing register during processing of a second instruction and store the results in a second general purpose register, wherein the second instruction is the next consecutive instruction after the first instruction. The inline thread sequence may be inserted in sequence with the thread and further configured to compare the difference between the result in the first and second general purpose register to a programmable threshold.

  • Publication number: 20200201767
    Abstract: A method, computer program product, and a computer system are disclosed for processing information in a processor that in one or more embodiments includes issuing from one of a plurality of processors an address translation invalidation instruction with a return marker, wherein the address translation invalidation instruction is to invalidate one or more address translation entries in one or more storage locations in the computer system; broadcasting the address translation invalidation instruction to one or more storage locations of one or more of the other processors; invalidating an address translation entry located in a storage location of the one or more storage locations; and returning information on the invalidated address translation entry to the issuing processor.
