Abstract
A system and method for reducing instability in an information handling system are disclosed. A method includes detecting a configuration change of a first memory device. Next, the method determines a device identifier for a second memory device depending on the configuration change. The method proceeds to update a Configurable Identification (CID) register in the second memory device with the device identifier.
Claims16
A method for managing device identifiers in an information handling system, comprising:
- receiving a modified first device identifier for a first memory device, the first device identifier being modified after initiation of a boot operation, wherein the first device identifier for the first memory device is self-modified by the first memory device;
- comparing the modified first device identifier for the first memory device with a second device identifier for a second memory device, wherein the second memory device is not capable of self-modifying the second device identifier;
- and
- as a result of the comparison, modifying the second device identifier for the second memory device.
A method for managing device identifiers in an information handling system including a first memory device capable of self-modifying a first device identifier for the first memory device and a second memory device not capable of self-modifying a second device identifier for the second memory device, comprising:
- receiving a self-modified first device identifier for the first memory device capable of self-modifying the first device identifier;
- and
- based on the self-modified first device identifier for the first memory device, modifying the second device identifier for the second memory device not capable of self-modifying the second device identifier.
An information handling system, comprising:
- a first memory device having a first device identifier;
- a second memory device having a second device identifier;
- and
- a management engine configured to:
- receiving a modified first device identifier for the first memory device, the first device identifier being modified after initiation of a boot operation for the information handling system, wherein the first device identifier for the first memory device is self-modified by the first memory device and the second memory device is not capable of self-modifying the second device identifier;
- comparing the modified first device identifier for the first memory device with the second device identifier for the second memory device;
- and
- as a result of the comparison, causing the second device identifier for the second memory device to be modified.
A method, comprising:
- detecting a configuration change associated with a first memory device of an information handling system, the configuration change occurring after initiation of a boot operation;
- identifying a change to at least one bit of a first device identifier for the first memory device, the change occurring as a result of the configuration change, wherein the first device identifier for the first memory device is self-modified by the first memory device as a result of the configuration change;
- and
- modifying a second device identifier for a second memory device based on the configuration change the modifying further based on the identified change to the at least one bit of the first device identifier for the first memory device, and wherein the second memory device is not capable of self-modifying the second device identifier for the second memory device.
