  • Patent number: 11645616
    Abstract: Technologies are described for verifying the integrity of data transmitted between a firmware and a baseboard management controller (“BMC”). During a first verification phase, a data integrity tool compares system inventory data provided by firmware protocols to a system inventory module to system inventory data in a device instance format. During a second verification phase, the data integrity tool verifies operation of a firmware conversion module by comparing the system inventory data in the device instance format to the system inventory data in a JavaScript Object Notation (“JSON”) format. During a third verification phase, the data integrity tool retrieves the system inventory data from a management server and compares the system inventory data retrieved from the management server to the system inventory data previously transmitted to the management server. Identified discrepancies can be utilized to modify the system inventory module, the firmware conversion module, or the management server.

  • Patent number: 11113070
    Abstract: Technologies are provided for automated identification of system devices to be disabled in a computing system and the disablement of the system devices during bootup of the computing system. In some embodiments, the computing system can execute a firmware configured to perform a bootup process of the computing system. The computing system includes multiple system devices. The firmware can generate program code for identifying a system device for disablement. The firmware can send the program code to a controller device curing the bootup process, where execution of the program code by the controller device generates data identifying one or several specific system devices to be disabled in the computing system. The firmware can then access such data from the controller device. Using the data, the firmware can determine that a specific system device to be disabled. The firmware can then disable that particular system device on a next bootup process.

  • Patent number: 11048570
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system includes an initialization component of a host. The initialization component obtains health data indicating that at least one hardware component of the host is in one of one or more predetermined health conditions when executed in a system management mode of the host. The initialization component then sends, to a service processor of the host, a message in accordance with a management protocol. The message includes the health data.

  • Patent number: 10838861
    Abstract: A firmware attempts to allocate memory address resources, such as memory addresses in a PCI I/O and a PCI memory address space, to bus devices in a multi-processor computing system. If an out-of-resource (OOR) condition occurs during allocation of the memory address resources, memory address resources can be re-allocated from stacks that were successfully allocated requested resources to stacks that were not successfully allocated requested resources. Memory address resources can also, or alternately, be re-allocated from sockets that were successfully allocated requested resources to sockets that were not successfully allocated requested resources. If stack-level or socket-level readjustment of the memory address resource allocation fails, a base memory address of a configuration memory address space can be lowered, and the allocation can be retried.

  • Patent number: 10776193
    Abstract: Technologies are disclosed for identifying and remediating correctable hardware errors. A firmware can detect a system management interrupt (“SMI”) generated by a hardware device responsive to the occurrence of a correctable error. Once the firmware has identified the device that generated the SMI, the firmware can determine whether an earliest recorded error generated by the identified device is longer ago than a threshold amount of time. If the earliest recorded error generated by the device is not longer ago than the threshold amount of time, the firmware can increment an error count for the device. The firmware can also determine whether the error count for the device exceeds a threshold. If the error count for the device exceeds the threshold, the firmware can generate an error notification for the device. The firmware can also implement a remedial action policy for the device.
