  • HARDWARE-BASED PRE-PAGE WALK VIRTUAL ADDRESS TRANSFORMATION INDEPENDENT OF PAGE SIZE UTILIZING BIT SHIFTING BASED ON PAGE SIZE
    Publication number: 20190188147
    Abstract: An apparatus includes a processor and a virtual address transformation unit coupled with the processor. The virtual address transformation unit includes a register. The virtual address transformation unit is configured to receive an indication of a virtual address and read, from the register, a current page size of a plurality of available page sizes. The virtual address transformation unit is also configured to determine a shift amount based, at least in part, on the current page size and perform a bit shift of the virtual address, wherein the virtual address is bit shifted by, at least, the determined shift amount.

  • Code fingerprint-based processor malfunction detection
    Patent number: 10318790
    Abstract: Techniques relate to fingerprint-based processor malfunction detection. A determination is made whether a fingerprint is present in software that is currently executing on the processor of the computer system. The fingerprint includes a representation of a sequence of behavior that occurs on the processor while the software is executing. The fingerprint corresponds to a type of malfunction. In response to determining that the fingerprint is not present in the software currently executing on the processor, monitoring of the software executing on the processor to determine whether the fingerprint is present continues. In response to determining that the fingerprint is present in the software executing on the processor, it is determined that the malfunction has occurred according to a type of the fingerprint that is present.

  • Compiling optimized entry points for local-use-only function pointers
    Patent number: 10310829
    Abstract: Embodiments relate to using a local entry point with an indirect call function. More specifically, an indirect call function configuration comprises a first application module having a target function of the indirect function call, a second application module with a symbolic reference to the target function of the indirect function call, and a third application module to originate an indirect function call. A compiler determines and indicates, in the program code, that the function pointer value resulting from a non-call reference of a function symbol is solely used to perform indirect calls in the same module, e.g. local-use-only. A linker or loader can read the indication the compiler made in the program code. The linker or loader use the local entry point associated with the target function if the target function is defined in the same module as the reference and is local-use-only.

  • Using transactional execution for reliability and recovery of transient failures
    Patent number: 10310952
    Abstract: Autonomous recovery from a transient hardware failure by executing portions of a stream of program instructions as a transaction. A start of a transaction is created in a stream of program instructions executing on a first processor of a multi-processor computer. A snapshot of a system state information is saved when the transaction begins. When the transaction ends, store data of the transaction is committed. If a transient hardware failure occurs, the transaction is aborted without notifying the computer software application that initiated the stream of program instructions. The transaction is re-executed on a second processor of the multi-processors, based on the saved snapshot of the system state information.

  • Using transactional execution for reliability and recovery of transient failures
    Patent number: 10289499
    Abstract: Autonomous recovery from a transient hardware failure by executing portions of a stream of program instructions as a transaction. A start of a transaction is created in a stream of executing program instructions. A snapshot of a system state information is saved when the transaction begins. When a predefined number of program instructions in the stream are executed, the transaction ends, and store data of the transaction is committed. A new transaction then begins. If a transient hardware failure occurs, the transaction is aborted without notifying the computer software application that initiated the stream of program instructions. The transaction is re-executed, based on the saved snapshot of the system state information.

    Patent number: 10289420
    Abstract: Embodiments relate to lightweight interrupts for floating point exceptions.

  • CONDITIONAL STACK FRAME ALLOCATION
    Publication number: 20190138438
    Abstract: A method for allocating memory includes an operation that determines whether a prototype of a callee function is within a scope of a caller. The caller is a module containing a function call to the callee function. In addition, the method includes determining whether the function call includes one or more unnamed parameters when a prototype of the callee function is within the scope of the caller. Further, the method may include inserting instructions in the caller to allocate a register save area in a memory when it is determined that the function call includes one or more unnamed parameters.

  • HINT INSTRUCTION FOR MANAGING TRANSACTIONAL ABORTS IN TRANSACTIONAL MEMORY COMPUTING ENVIRONMENTS
    Publication number: 20190138346
    Abstract: When executed, a transaction-hint instruction specifies a transaction-count-to-completion (CTC) value for a transaction. The CTC value indicates how far a transaction is from completion. The CTC may be a number of instructions to completion or an amount of time to completion. The CTC value is adjusted as the transaction progresses. When a disruptive event associated with inducing transactional aborts, such as an interrupt or a conflicting memory access, is identified while processing the transaction, processing of the disruptive event is deferred if the adjusted CTC value satisfies deferral criteria. If the adjusted CTC value does not satisfy deferral criteria, the transaction is aborted and the disruptive event is processed.

    Patent number: 10282276
    Abstract: Techniques relate to fingerprint-initiated trace extraction. A determination is made of whether a fingerprint is present in software that is currently executing on a processor of a computer system. The fingerprint comprises a representation of a sequence of behavior that occurs in the processor while the software is executing. In response to determining that the fingerprint is not present in the software currently executing on the processor, monitoring continues for the software executing on the processor to determine whether the fingerprint is present. In response to determining that the fingerprint is present in the software executing on the processor, a trace is triggered of a code segment of the software corresponding to when the fingerprint is recognized. The trace is for a record of instructions of the code segment of the software.

  • Mechanism for creating friendly transactions with credentials
    Patent number: 10270775
    Abstract: One or more transactions may request or be assigned tokens within a transactional memory environment. A transaction may be created by at least one thread. A first transaction that includes a first token type may be received. A request may be received for a for a potential conflict check between the first transaction and a second transaction. In response to receiving the transaction potential conflict check, the first transaction and the second transaction are determined to be conflicting or not conflicting. The second transaction is assigned a token type in response to the determination of the transaction potential conflict check between the first transaction and the second transaction.

  • COMPILER OPTIMIZATIONS FOR VECTOR OPERATIONS THAT ARE REFORMATTING-RESISTANT
    Publication number: 20190108005
    Abstract: An optimizing compiler includes a vector optimization mechanism that optimizes vector operations that are reformatting-resistant, such as source instructions that do not have a corresponding reformatting operation, sink instructions that do not have a corresponding reformatting operation, a source instruction that is a scalar value, a sink instruction that may produce a scalar value, and an internal operation that depends on lanes being in a specified order. The ability to optimize vector instructions that are reformatting-resistant reduces the number of operations to improve the run-time performance of the code.
