US 2026/0310362 A1 · PERSISTENT MEMORY ACROSS UPDATES

Abstract

A method for updating a device includes receiving an instruction to update from a first configuration in the device to a second configuration, where a first heap memory allocated to the first configuration includes multiple first allocated memory blocks and corresponding first memory blocks metadata. The method also includes performing a warm reset, the reset including determining, based on the first memory blocks metadata, that when updating from the first configuration to the second configuration, data of at least one of the first allocated memory blocks should be persisted to a second heap memory allocated to the second configuration, and causing the device to update from the first configuration to the second configuration, where the update includes persisting, based on the first memory blocks metadata, the data of at least one of the first allocated memory blocks to a second heap memory allocated to the second configuration.

Dependent claims

A method comprising:

determining to update a device from a first configuration of the device to a second configuration of the device, wherein a first heap memory allocated to the first configuration comprises a plurality of memory blocks and corresponding memory blocks metadata;
determining, based on the corresponding memory blocks metadata, that data of at least one memory block of the plurality of memory blocks should be persisted to a second heap memory allocated to the second configuration when updating the device;
generating at least two portions of the first heap memory by dividing the first heap memory, wherein a portion of the at least two portions comprises the at least one memory block storing the data that should be persisted;
and
causing the device to update from the first configuration to the second configuration, wherein causing the device to update comprises persisting the data of the portion to the second heap memory.

A system comprising:

a first heap memory allocated to a first configuration of a device, the first heap memory comprising a plurality of memory blocks and corresponding memory blocks metadata;
and
control circuitry to:
determine to update a device from the first configuration of the device to a second configuration of the device;
determine, based on the corresponding memory blocks metadata, that data of at least one memory block of the plurality of memory blocks should be persisted to a second heap memory allocated to the second configuration when updating the device;
generate at least two portions of the first heap memory by dividing the first heap memory, wherein a portion of the at least two portions comprises the at least one memory block storing the data that should be persisted;
and
cause the device to update from the first configuration to the second configuration, wherein the control circuitry is to persist the data of the portion to the second heap memory.
