Publication number: 20240037237Abstract: Methods and systems for managing the operation of data processing systems are disclosed. A data processing system may include a computing device that may enter various operating states by performing various types of startups. The startups may include use of code bases for which the computing device may not inherently be able to validate. To reduce risk of using the code bases, the computing device may perform processes to validate the code bases prior to using the code bases. Additionally, the computing devices may limit the types of interfaces that may be established during the startups while allowing other types of interfaces to be established to provide startup flexibility.Type: ApplicationFiled: July 26, 2022Publication date: February 1, 2024Inventors: Sanjeev Singh, Paul W. Vancil, Mukund Khatri, Prashanth Giri, Wei G. Liu

Patent number: 11836502Abstract: An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with the plurality of hardware devices. The BMC includes executable instructions for beginning execution of a first BMC firmware stack, and during execution of the first BMC firmware stack, halt execution of the first BMC firmware stack, and begin execution of a second BMC firmware stack. At least a portion of the executable instructions used to generate the first BMC firmware stack are different than the executable instructions used to generate the second BMC firmware stack.Type: GrantFiled: June 14, 2021Date of Patent: December 5, 2023Assignee: Dell Products L.P.Inventors: Akkiah Choudary Maddukuri, Chandrasekhar Mugunda, Prashanth Giri, Eugene David Cho, Donald W.

Patent number: 11829248Abstract: An information handling system includes a memory and a baseboard management controller. The memory includes a recovery partition including a recovery kernel, a first boot partition including first firmware, and a second boot partition including backup firmware. The baseboard management controller (BMC) attempts a first boot operation of the first firmware in the first boot partition. In response to a failure of the first boot operation, the BMC attempts a second boot operation of the backup firmware in the second boot partition. In response to a failure of the second boot operation, the BMC operates a recovery kernel. During the operation of the recovery kernel, the BMC provides a firmware request to an enclosure controller, receives blocks of correct firmware from a functioning baseboard management controller, stores the blocks of correct firmware in the first boot partition, attempts and completes a third boot operation of the correct firmware.Type: GrantFiled: September 23, 2021Date of Patent: November 28, 2023Assignee: Dell Products L.P.Inventors: Prashanth Giri, Murali Somarouthu, Babu Chandrasekhar

Patent number: 11762756Abstract: Methods, systems, and devices for providing for trust during startup of an information handling system (IHS) are disclosed. When an IHS starts up, data may be read into memory and used by a processor of the IHS to begin execution of a startup management entity that places the IHS into a desired operating system. To reduce the likelihood of the data used for IHS startup causing the IHS to enter an undesired state (e.g., due to data corruption or intentional action), the data may be verified prior to be being read into memory. If the data is unverifiable, then corrective action may be taken.Type: GrantFiled: October 7, 2021Date of Patent: September 19, 2023Assignee: Dell Products L.P.Inventors: Prashanth Giri, Michael Emery Brown

Patent number: 11755404Abstract: An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with multiple hardware devices of the IHS. The BMC includes executable instructions for monitoring a parameter of one or more of the hardware devices when a custom BMC firmware stack is executed on the BMC. The instructions that monitor the parameter are separate and distinct from the instructions of the custom BMC firmware stack. The instructions also control the BMC to perform one or more operations to remediate an excessive parameter when the parameter exceeds a specified threshold.Type: GrantFiled: June 14, 2021Date of Patent: September 12, 2023Assignee: Dell Products, L.P.Inventors: Eugene David Cho, Prashanth Giri, Timothy M. Lambert, Akkiah Choudary Maddukuri, Chandrasekhar Mugunda, Arun Muthaiyan, Sreeram Veluthakkal

Patent number: 11726879Abstract: An information handling system includes a first memory and a baseboard management controller. The first memory stores a first firmware partition and a second firmware partition. The baseboard management controller includes a second memory. The baseboard management controller begins execution of a DM-Verity daemon, and performs periodic patrol reads of the first firmware partition. The baseboard management controller detects one or more block failures in the first firmware partition, and stores information associated with the one or more block failures in a message box of the second memory. In response to the entire first firmware partition being scanned, the baseboard management controller switches a boot partition from the first firmware partition to the second firmware partition, and initiates a reboot of the information handling system.Type: GrantFiled: July 12, 2021Date of Patent: August 15, 2023Assignee: Dell Products L.P.Inventors: Michael E.
