Abstract

To preserve error context during a reboot of a computing device, firmware within the computing device can be configured to implement a method that includes determining where the error context is stored in volatile memory. The method can also include identifying a plurality of recorder regions in non-volatile memory that have been assigned to store the error context. The plurality of recorder regions can be disaggregated across a plurality of distinct non-volatile memory regions. The method can also include flushing the error context from a plurality of different volatile memory locations to the plurality of recorder regions in response to detecting a trigger. The flushing can occur prior to the reboot of the computing device. The method can also include restoring at least some of the error context to the volatile memory after the computing device has been rebooted.
