摘要:
A computing system can include a platform firmware to monitor hardware errors and to notify an operating system when a corrective action is to be performed to address a hardware error. The computing system can also include an extended error log to describe a hardware error. The computing system can further include an action record to direct the operating system to perform the corrective action to address the hardware error.

Embodiments of a hardware processor including a plurality of machine state registers (MSRs) are described. At least one of the MSRs includes an erroring logical processing (ELP) bit which when set, indicates that a particular thread executing on the hardware processor caused an error.

A computing system can include a machine check counter (MCC) including a current value. The current value indicates a system reboot resetting hardware of the computing system. The machine check counter includes a model specific register including a counter indicating the current value, the current value to be incremented upon the system reboot.

In one embodiment, a processor includes a plurality of cores including a first core to be reserved for execution in a protected domain, the first core to be hidden from an operating system. The processor may further include a filter coupled to the plurality of cores, where the filter includes a plurality of fields each associated with one of the plurality of cores to indicate whether an interrupt of the protected domain is to be directed to the corresponding core. Other embodiments are described and claimed.

Embodiments of an invention for signaling software recoverable errors are disclosed. In one embodiment, a processor includes a first unit, a programmable indicator, and a second unit. The first unit is to detect a poison error. The programmable indicator is to indicate whether the poison error is signaled as a machine check error or as one of a fault and a system management interrupt. The second unit is to signal the poison error as one of a fault and a system management error responsive to the programmable indicator.

In an embodiment, a processor for reverse translation includes a plurality of processing engines (PEs) to execute threads and a reverse translation circuit. The reverse translation circuit is to: determine a target module address of a corrupt portion of a memory module; determine a plurality of system physical address (SPA) addresses associated with the memory module; and for each SPA address in the plurality of SPA addresses, translate the SPA address into a translated module address, and in response to a determination that the translated module address matches the target module address, log the SPA address as a result of a reverse translation of the target module address. Other embodiments are described and claimed.
摘要:
Methods and apparatus to provide improved input/output (I/O) address translation lookaside buffer performance are described. In one embodiment, one or more entries of a cache (e.g., an I/O address translation lookaside buffer) are locked in response to a request to lock the one or more entries. Other embodiments are also described.
摘要:
Systems, methods, and apparatus to retarget platform interrupts in a reconfigurable system. Some embodiments include identifying each processor of a multiprocessor system capable of processing Corrected Platform Error Interrupts, adding each processor capable of processing Corrected Platform Error Interrupts to a list of potential Corrected Platform Error Interrupt targets, and updating an interrupt table with a target processor for an interrupt, wherein the interrupt table is accessible by an interrupt controller to target platform interrupts. Another embodiment includes receiving a request to disable the first processor in a multiprocessor apparatus, determining if the first processor is a Corrected Platform Error Interrupt destination, and determining if the second processor is capable of processing Corrected Platform Error Interrupts. This embodiment also includes reprogramming an interrupt controller to route interrupts to the second processor instead of the first processor and disabling the first processor.
