摘要： Apparatus, systems, and methods to manage memory operations are described. In one example, a controller comprises logic to receive a first transaction to operate on a first data element in a volatile memory, determine whether the first data element is to be stored in a nonvolatile memory, and in response to a determination that the first data element is to be stored in a nonvolatile memory, to forward the first transaction to the memory controller coupled to the nonvolatile memory. Other examples are also disclosed and claimed.

摘要： Technologies for system management interrupt (“SMI”) handling include a number of processor cores configured to enter a system management mode (“SMM”) in response to detecting an SMI. The first processor core to enter SMM and acquire a master thread lock sets an in-progress flag and executes a master SMI handler without waiting for other processor cores to enter SMM. Other processor cores execute a subordinate SMI handler. The master SMI handler may direct the subordinate SMI handlers to handle core-specific SMIs. The multi-core processor may set an SMI service pending flag in response to detecting the SMI, which is cleared by the processor core that acquires the master thread lock. A processor core entering SMM may immediately resume normal execution upon determining the in-progress flag is not set and the service pending flag is not set, to detect and mitigate spurious SMIs. Other embodiments are described and claimed.

摘要： Embodiments of apparatus, computer-implemented methods, systems, devices, and computer-readable media are described herein for a computing device with a platform entity such as an interrupt handier configured to notify an operating system or virtual machine monitor executing on the computing device of an input/output error-containment event. In various embodiments, the interrupt handler may be configured to facilitate recovery of a link to an input/output device that caused the input/output error-containment event, responsive to a directive from the operating system or virtual machine monitor.

摘要： A microcode (uCode) hot-upgrade method for bare metal cloud deployment and associated apparatus. Under the uCode hot-upgrade method, a uCode path is received at an out-of-band controller (e.g., baseboard management controller (BMC)) and buffered in a memory buffer in the out-of-band controller. The out-of-band controller exposes the memory buffer as a Memory-Mapped Input-Output (MMIO) range to a host CPU. A uCode upgrade interrupt service is triggered to upgrade uCode for one or more CPUs in a bare-metal cloud platform during runtime of a tenant host operating system (OS) using an out-of-bound process. This innovation enables cloud service providers to deploy uCode hot-patches to bare metal servers for live-patch without touching the tenant operating system environment.

摘要： A microcode (uCode) hot-upgrade method for bare metal cloud deployment and associated apparatus. The uCode hot-upgrade method applies a uCode patch to a firmware storage device (e.g., BIOS SPI flash) through an out-of-band controller (e.g., baseboard management controller (BMC)). In conjunction with receiving a uCode patch, a uCode upgrade interrupt service is triggered to upgrade uCode for one or more CPUs in a bare-metal cloud platform during runtime of a tenant host operating system (OS) using an out-of-bound process. This innovation enables cloud service providers to deploy uCode hot-patches to bare metal servers for persistent storage and live-patch without touching the tenant operating system environment.

摘要： An event management resource monitors a processor environment. In response to detecting occurrence of a trigger event in the processor environment, the event management resource initiates a transfer of processor cache data from volatile storage in the processor environment to non-volatile memory. The event management resource can be configured to produce status information associated with the transfer of cache data to a respective non-volatile memory resource. The event management resource stores the status information in a non-volatile storage resource for later retrieval. Accordingly, status information associated with the event causing the transfer is available for analysis on subsequent power up or reboot of a respective computer system.
