  • Patent number: 10777296
    Abstract: Embodiments of information handling systems (IHSs) and methods are provided herein to dynamically detect and recover from thermally induced memory failures. Some embodiments include receiving an interrupt corresponding to a memory failure, detecting a current temperature of one or more memory components, and performing a series of memory tests on a specific block of memory within the memory components if the current temperature exceeds a maximum operating temperature specified for the memory components. Some embodiments include storing original contents of the specific block of memory within another memory component of the IHS, performing a first memory test on the specific block of memory at the current temperature, subsequently performing a second memory test on the specific block of memory at a temperature significantly lower than the current temperature, and determining that the memory failure is a thermally induced memory failure if the first memory test fails and the second memory test passes.

  • Publication number: 20200285534
    Abstract: Embodiments of information handling systems (HSs) and computer-implemented methods are provided herein to detect and recover from spurious PCIe device resets. One embodiment of a disclosed method is performed by a host processor of an IHS that includes a plurality of Peripheral Component Interconnect Express (PCIe) devices, each including a set of PCIe configuration registers containing configuration settings for the PCIe device. The disclosed method includes generating, in response to the IHS transitioning from a lower power state to a higher power state, a PCIe device table containing the configuration settings stored within the set of PCIe configuration registers for each of the PCIe devices; determining, in response to detecting a system management interrupt (SMI), whether or not a spurious reset has occurred for at least one of the PCIe devices; and recovering the at least one PCIe device if said determining indicates that a spurious reset has occurred for the at least one PCIe device.

  • Publication number: 20200159302
    Abstract: Embodiments of information handling systems (IHSs) and methods are provided herein to automatically detect and recover from boot failures, such as no power failures and no POST failures, without suffering the information loss that typically occurs in conventional recovery methods. One embodiment of an IHS disclosed herein includes a system real-time clock (RTC) configured to maintain current date and time values, a host processor configured to execute boot firmware and perform a Power-On Self-Test (POST) during a boot process for the IHS, and an embedded controller (EC) configured to execute embedded controller firmware during the boot process to detect a no power failure or a no POST failure, and reset or remove power from the system RTC if a no power failure or a no POST failure is detected.

  • Publication number: 20200073832
    Abstract: Systems and methods are provided that may be implemented to hide operating system kernel data in system management mode memory. An information handling system includes a system memory, central processing unit (CPU), and Basic Input Output System (BIOS). The CPU is operable in a system management mode and is programmable to specify an SMM region of the system memory that is only accessible when the CPU is operating in the SMM. The BIOS is programmed to save kernel data from a non-SMM region of the system memory to the SMM region and then clear the kernel data from the non-SMM region in response to an operating system (OS) generating a system management interrupt (SMI) and to restore the kernel data to the non-SMM region of the system memory from the SMM region in response to the OS generating a SMI.

  • Patent number: 10545769
    Abstract: A method performed by an information handling system, the method including bifurcating, by a processor of the information handling system, an I/O unit (IO unit) of the information handling system into a first root port and a second root port, wherein the first root port comprises a first pre-determined number of first lanes of the IO unit and the second root port comprises the first pre-determined number of second lanes of the IO unit. The method further including discovering, by the processor, a first I/O device (IO device) coupled to the IO unit, wherein the first IO device utilizes a first lane width that is greater than the first pre-determined number of lanes, and in response to discovering the first IO device, bifurcating, by the processor, the IO unit into a third root port, wherein the third root port comprises the first lanes and the second lanes.
