摘要:
In an information handling system, when a memory location is accessed and there is a bit error detected in that memory location then the memory location is logged into an error-log. The memory locations of the logged bit errors stored in the error-log are evaluated to determine whether there is one or more bit errors in a particular memory range, e.g., a contiguous range of memory locations. If there is one or more bit errors in a memory range, then that memory range may be hot ejected, e.g., disabled from use by the operating system. The bit error may be single bit error and/or multiple bit errors of a memory location.

A first computational device receives a response generated by a second computational device for a third computational device. A target that is suitable for use by the third computational device is determined. The response is transmitted with an address of the target to the third computational device.
摘要:
A system for identifying peripheral devices in an information handling system uses a path-based signature for each peripheral component device. A static table is included for listing the path of each peripheral device and is accessible to the Basic Input-Output System (BIOS). The BIOS is configured to identify peripheral components associated and determine a path-base device signature for each peripheral component.

In an information handling system, a plurality of system resources are usable by at least one processor. An affinity structure includes elements describing the relative accessibility of the plurality of system resources to the processor. An affinity manager adjusts the affinity structure in response to a least a first one of the plurality of system resources operating outside of at least one operating parameter.

In accordance with certain embodiments of the present disclosure, an information handling system is provided. The information handling system may include a plurality of processors, each processor comprising multiple cores, a memory system coupled to the plurality of processors, and a controller coupled to the plurality of processors. The controller may be configured to: receive a local system management interrupt (SMI) signal regarding an error associated with at least one of the multiple cores, determine that the received local SMI signal triggers a global SMI based on a global SMI trigger rule, cause the plurality of processors to enter a global system management mode (SMM), and log the error in a shared resource shared by the plurality of processors during the global SMM.
摘要:
An information handling system includes a processor having access to a system memory. The system is operable to detect a thermal alert and identify an associated portion of system memory. The system may then modify memory allocation information used by an operating system to allocate system memory. When the thermal alert indicates a rising memory module temperature that exceeds a specified threshold, the modification of the memory allocation information causes the memory to appear to be more “distant” from the system processor(s) and thereby allocated less preferentially than other memory. If the temperature continues to rise beyond a higher threshold, a second modification of the memory allocation information is performed to simulate a “hot eject” of the memory module. As the memory module cools, the memory allocation information can be restored to simulate a hot add of the memory module and to restore the proximity of the memory module.
摘要:
A system and method is disclosed in which, during the execution of an interrupt handling sequence in one of the processor of a multiprocessor system, a processors write a reason code to a status register to identify the cause of the interrupt. The BIOS code of the system writes to an interrupt initiation register to cause each of the processors to enter an interrupt handling sequence. Each of the processors of the system handling the interrupt on the basis of the content of the status register, resulting in each of the processors synchronously handling an interrupt for an event that would otherwise result in a local interrupt.
摘要:
Option ROMs associated with information handling system processing components is selectively disabled to reduce the time associated with one or more boots of the information handling system, such as during deployment of applications after manufacture of the information handling system. An Option ROM selector module identifies one or more Option ROMs to disable at a boot, such as Option ROMs associated with processing components that are not needed for deployment of applications, and communicates the disabled Option ROMs to an Option ROM boot execution controller of the information handling system, such as with SMBIOS tokens. At a subsequent boot, the Option ROM execution controller prevents the BIOS from loading disabled Option ROMs for execution so that boot time is reduced with impact to the deployment of applications.
