Non-volatile memory update tracking

摘要

A technique includes performing an update to a location of a non-volatile memory. The update is created by execution of at least one machine executable instruction of a plurality of machine executable instructions. The technique includes using a processor-based machine to selectively track the update to allow recovery of the execution to a given consistency point based at least in part on whether the machine executable instruction(s) creating the update are located within a synchronized section of the plurality of machine executable instructions.

1. A method comprising:
performing an update to a location of a non-volatile memory, the non-volatile memory accessible at a byte level granularity via central processing unit store instructions, the update created by execution of at least one machine executable instruction of a plurality of machine executable instructions; and using a processor-based machine to selectively track the update to allow recovery of the execution to a given consistency point based at least in part on whether the at least one machine executable instruction is located within a synchronized section of the plurality of machine executable instructions, wherein the synchronized section comprises multiple instructions of the plurality of machine executable instructions, wherein the synchronized section comprises a lock-based section, wherein using the processor-based machine to selectively track the update is based at least in part on a determination of whether the update can be rolled back, wherein the update is outside of the synchronized section, and determining whether the update can be rolled back comprises: determining whether another synchronized section is executed before the synchronized section comprising the lock-based section can be rolled back.
