Patent number: 11592890Abstract: Embodiments of a system, method, and memory storage device for managing performance optimization of applications executed by an Information Handling System (IHS) are described. In an illustrative, non-limiting embodiment, an IHS may include computer-executable instructions to receive telemetry data associated with an operating behavior of the IHS. Using the telemetry data, the IHS generates a profile recommendation from the received telemetry data using a machine learning (ML) service, and adjusts a core stall management mechanism of a second processor to optimize a performance of the IHS. The second processor performs at least a portion of the operating behavior of the IHS.Type: GrantFiled: March 1, 2021Date of Patent: February 28, 2023Assignee: Dell Products, L.P.Inventors: Chia-Chi Ho, Thomas Alexander Shows, Ya-Chen Tsai, Chung-Wei Wang, Yi-Chung Cheng

Patent number: 11513810Abstract: A method of configuring a display device interface (DDI) detects a trigger signal, generated by a display device. If the trigger signal is associated with a power on event, a full configuration of the DDI is performed, including loading display device capability information provided by the display device into DDI configuration registers and setting one or more DDI configuration parameters accordingly. If the trigger signal is associated with resume event, rather than a power on event, a modified fast link resume operation may be performed to route the trigger signal to a controller configured to explicitly write display device capability information to the appropriate DDI configuration registers before setting the corresponding DDI configuration parameter accordingly. The DDI may include a re-timer, between the DDI source and sink, configured to snoop the explicit write transaction such that the re-timer configuration is also updated.Type: GrantFiled: July 15, 2021Date of Patent: November 29, 2022Assignee: Dell Products L.P.Inventors: Chung-Wei Wang, Chih-Chung Lin, You-Liang Chen, Pei-Yu Wang

Patent number: 10355505Abstract: A system, method, and computer-readable medium are disclosed for detecting when a lower power adapter is coupled with an information handling system having higher power requirements. More specifically, in certain embodiments, a circuit (such as an embedded controller (EC)) detects an adapter wattage when an adapter plug-in is detected. If a lower wattage power adapter is detected (e.g., a 45 W power adapter), the embedded controller activates a signal (e.g., an AC_DISABLE signal) to stop powering the information handling system from the adapter. In certain embodiments, the information handling system is powered from a battery associated with the information handling system when the power adapter power capacity does not satisfy the power requirements of the information handling system. In certain embodiments, the circuit substantially simultaneously generates a low power warning. In certain embodiments, the adapter wattage may be detected via an adapter identifier (e.g.Type: GrantFiled: March 10, 2014Date of Patent: July 16, 2019Assignee: Dell Products L.P.Inventors: Adolfo S.
