Abstract: In an example, a computer system includes: a hardware platform including a processor, system memory, and a plurality of input/output (IO) devices, the processor including a controller having a trace and optimize function controller (TOF); and a software platform including an operating system (OS) executing on the hardware platform; wherein the TOF is configured to communicate with the processor, the system memory, and the plurality of IO devices to obtain current settings thereof and to determine final settings for the processor, the system memory, and the plurality of IO devices based on the current settings; and wherein the controller is configured to control the processor, the system memory, and the plurality of IO devices based on the final settings.

Abstract: A computer-implemented method for instruction-level tracing for analyzing processor failure includes detecting a failure during operation of a processor circuit. The method further includes parsing a miscompare trace to determine a plurality of opcodes executed by the processor prior to the failure. The method further includes generating a workload comprising a set of opcodes by filtering the set of opcodes from the miscompare trace. The method further includes performing a consistency check of the workload to determine a commit ratio of the workload, the commit ratio indicative of a number of times the failure occurs when the workload is executed a predetermined number of times. The method further includes using the workload for debugging the failure based on the commit ratio being above a predetermined threshold.

Abstract: An apparatus for core repair includes a failure analysis and recovery (“FAR”) probe that accesses a core of a processor and units of the core over a low-level communication bus while the core is operational after a failure notification. The FAR probe compares operational data of the core versus vital product data (“VPD”) while the core is running tests and a thermal, power, functional (“TPF”) workload to determine if the core is in a degraded state and runs tests to identify a failure after determining that the core is in a degraded state. The FAR probe adjusts parameters of the core in response to identifying a failure of the core and re-evaluates the core to determine if the core is functional. The FAR probe returns the core to service after determining that the core is functional. The FAR probe operates independent of other processor cores while the cores are operational.
