  • Publication number: 20220019426
    Abstract: Methods, apparatus, and systems for upgradable microcode (uCode) loading and activation in runtime for bare metal deployments that support runtime update of the uCode loading procedure as well as dynamic load of activation procedure(s) specific to uCode patch and activation policy specific to users. The solution provides several advantages, including enabling cloud service providers to hot-patch the uCode through a standalone uCode loader runtime service in BIOS firmware for bare metal deployment without tenant system involvement. The support of runtime update of uCode loading procedures decouples uCode loading logic from uCode loader framework. This removes dependencies on the uCode loader runtime service when needing to update the uCode loading logic.

  • Patent number: 11222119
    Abstract: Technologies for secure native code invocation include a computing device having an operating system and a firmware environment. The operating system executes a firmware method in an operating system context using a virtual machine. In response to invoking the firmware method, the operating system invokes a callback to a bridge driver in the operating system context. In response to the callback, the bridge driver invokes a firmware runtime service in the operating system context. The firmware environment executes a native code handler in the operating system context in response to invoking the firmware runtime service. The native code handler may be executed in a de-privileged container. The firmware method may process results data stored in a firmware mailbox by the native code handler, which may include accessing a hardware resource using a firmware operation region.

  • Publication number: 20210263779
    Abstract: Embodiments of systems, apparatuses and methods provide enhanced function as a service (FaaS) to users, e.g., computer developers and cloud service providers (CSPs). A computing system configured to provide such enhanced FaaS service include one or more controls architectural subsystems, software and orchestration subsystems, network and storage subsystems, and security subsystems. The computing system executes functions in response to events triggered by the users in an execution environment provided by the architectural subsystems, which represent an abstraction of execution management and shield the users from the burden of managing the execution. The software and orchestration subsystems allocate computing resources for the function execution by intelligently spinning up and down containers for function code with decreased instantiation latency and increased execution scalability while maintaining secured execution.

  • Publication number: 20210255915
    Abstract: Technologies for composing a managed node with multiple processors on multiple compute sleds to cooperatively execute a workload include a memory, one or more processors connected to the memory, and an accelerator. The accelerator further includes a coherence logic unit that is configured to receive a node configuration request to execute a workload. The node configuration request identifies the compute sled and a second compute sled to be included in a managed node. The coherence logic unit is further configured to modify a portion of local working data associated with the workload on the compute sled in the memory with the one or more processors of the compute sled, determine coherence data indicative of the modification made by the one or more processors of the compute sled to the local working data in the memory, and send the coherence data to the second compute sled of the managed node.

  • Publication number: 20210248026
    Abstract: Techniques and mechanisms for a processor to efficiently identify a circuit resource as being a source of data poisoning. In an embodiment, metadata is communicated, in association with a communication of poisoned data to which the metadata pertains, to a first circuit block of a processor. The metadata indicates a poisoned state of the data, wherein the metadata identifies a second circuit block—which is included in or coupled to the processor—as being a poisoner of the data. Based on the metadata, the first circuit block generates a fault message which identifies the second circuit block as the poisoner of the data. In another embodiment, the processor further comprises the second circuit block, which poisons the data (based on the detection of an error condition) by providing in the metadata a unique identifier which is assigned to the second circuit block.

The read from memory instruction is to indicate a source memory operand and a destination storage location. The processor also includes an execution unit coupled with the decode unit. The execution unit, in response to the read from memory instruction, is to read data from the source memory operand, store an indication of defective data in an architecturally visible storage location, when the data is defective, and complete execution of the read from memory instruction without causing an exceptional condition, when the data is defective. Other processors, methods, systems, and instructions are disclosed.

  • Patent number: 11054876
    Abstract: A non-volatile random access memory (NVRAM) is used in a computer system to enhance support to sleep states. The computer system includes a processor, a non-volatile random access memory (NVRAM) that is byte-rewritable and byte-erasable, and power management (PM) module. A dynamic random access memory (DRAM) provides a portion of system address space. The PM module intercepts a request initiated by an operating system for entry into a sleep state, copies data from the DRAM to the NVRAM, maps the portion of the system address space from the DRAM to the NVRAM, and turns off the DRAM when transitioning into the sleep state. Upon occurrence of a wake event, the PM module returns control to the operating system such that the computer system resumes working state operations without the operating system knowing that the portion of the system address space has been mapped to the NVRAM.
