Problems solved by technology

[0002] Memory Patrol Scrub UCE is an unrecoverable UCE error detected in the memory inspection mode. This UCE error can be downgraded to a repairable CE error after BIOS processing, but the current BIOS cannot distinguish between a PatrolScrub UCE degraded CE and a normal CE. , and the BIOS processing mechanism for common CE errors is that only when the error count meets the error threshold, it will be reported to the BMC for recording, because common CE errors occur frequently, and may occur hundreds of times a day. If each one triggers an SMI interrupt The processing is easy to cause server downtime, but this causes Patrol Scrub UCE degraded CE to be missed when the error threshold is not met, just like ordinary CE

Embodiment Construction

[0033] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0034] CE (corrected error), correctable error. When the memory check encounters an error, the CPU can correct the error at this time without affecting any process of the system, and it is CE at this time.

[0035] UCE (uncorrect error), uncorrectable error. It means that the system hardware cannot directly handle the memory recovery error, which is...

Abstract

The invention provides a fault processing method for a memory CE. The fault processing method comprises the steps of enabling a BIOS to judge whether Patrol Scrub UCE occurs or not by reading a presetregister; if not, judging whether the common CE count meets a missed error threshold value or not; and if the Patrol Scrub UC or the common CE count meets the missed error threshold value, triggeringSMI interruption. According to the invention, when the Patrol Scrub UCE occurs, SMI interruption is triggered the BIOS is prevented from counting as a common CE, so that the BIOS can discover the Patrol Scrub UCE in time; server operation and maintenance personnel can obtain memory fault information in time; and monitoring of the memory state of the server is facilitated. The invention further provides a fault processing system for the memory CE, a computer readable storage medium and fault processing equipment for the memory CE, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of servers, in particular to a memory CE fault handling method, system and related devices. Background technique [0002] Memory Patrol Scrub UCE is an unrecoverable UCE error detected in the memory inspection mode. This UCE error can be downgraded to a repairable CE error after BIOS processing, but the current BIOS cannot distinguish between a PatrolScrub UCE degraded CE and a normal CE. , and the processing mechanism of BIOS for ordinary CE errors is that only when the error count meets the error threshold, it will be reported to the BMC for recording, because the frequency of ordinary CE errors is very high, and it may occur hundreds of times a day. If each one triggers an SMI interrupt Processing can easily cause server downtime, but in this way, CEs degraded by Patrol Scrub UCE are missed when they do not meet the error threshold, just like ordinary CEs. This processing mechanism is flawed, because Pat...
