  • Patent number: 11995172
    Abstract: Accelerator access control whereby an application's access to an accelerator is revoked in order to allow the system to perform a system function. In one or more embodiments, when an application is executing, a credit system is utilized to provide credits for controlled access to the accelerator. When request information is received to remove access to a credit associated with the application's access to the accelerator, the credit is marked to fail with operating system interfaces. Also, in one or more embodiments, if the credit is in use for accessing the accelerator, an effective address associated with the credit is unmapped from the accelerator.

  • Publication number: 20240069980
    Abstract: Method, computer program product, and computer system are provided. A first migration of a running logical partition (LPAR) is performed from a first-generation computer to a second-generation computer. Availability of a facility differs between the first- and second-generation computers. Upon completion of the first migration, an operating system of the running LPAR detects whether a required facility in use on the first-generation computer is available on the second-generation computer. Operating system takes an action to continue an orderly execution of the LPAR, the operating system, and threads of an application in the LPAR depending on the availability of the required facility. A second migration is performed of the running LPAR from the second-generation computer back to the first-generation computer. The required facility is available on the first-generation computer. The operating system restores access to threads of the application to the required facility.

  • Patent number: 11656933
    Abstract: A processor may receive a software fix package. The processor may apply an interim software code fix of the software fix package to software of a device, where the interim software code fix includes adjusting one or more tunable computing parameters to one or more first values. The processor may identify that a reboot of the device is recommended for application of a permanent code fix of the software fix package. The processor may identify that the device was not rebooted after receipt of the software fix package. The processor may determine that a dynamic reconfiguration event has taken place. The processor may apply, automatically, one or more second values for the one or more tunable computing parameters associated with the interim software code fix of the software fix package.

  • Patent number: 11520612
    Abstract: In an embodiment, a guest operating system (OS) running on a virtual machine (VM) detects a VM migration, where the embodiment comprises storing, by the guest OS, a VM identifier (VMID) provided by the VM and a first host identifier (HID) provided by a host computer system in a computer memory. The embodiment also comprises determining, by the guest OS, that the VM performs migrations that are transparent to the guest OS. The embodiment further comprises detecting, by the guest OS, that the VM has been migrated based on a comparison of the first HID to a second HID provided to the guest OS in response to an HID request from the guest OS.

  • Patent number: 11436043
    Abstract: For a process of an operating system, it is detected that a live migration has occurred, the live migration comprising a change in a hardware characteristic of a computer system on which the process executes. A first message is broadcast to a set of processors, the first message causing each processor in the set of processors to enter a waiting state. While each of the set of processors is in the waiting state, a portion of a set of program instructions of the operating system is modified.
