  • Patent number: 11789889
    Abstract: Apparatuses, methods, and computer-readable media are provided for operating a port manager to detect a first link condition or a second link condition of a circuitry. Under the first link condition, a first link between a downstream port of the circuitry and an upstream port of a switch is compatible to a first protocol, and a second link between a downstream port of the switch and an upstream port of a device is compatible to the second protocol. Under the second link condition, the first link exists and is compatible to the first protocol, while there is no second link being compatible to the second protocol. The port manager is to operate the downstream port of the circuitry according to the second protocol on detection of the first link condition, or according to the first protocol on detection of the second link condition. Other embodiments may be described and/or claimed.

  • Publication number: 20230123174
    Abstract: Examples disclosed herein include are computing device hardware components, computing devices, systems, machine-readable mediums, and interconnect protocols that provide for code object measurement of a peripheral device and a method for accessing the measurements to verify integrity across a computing interconnect (e.g., Peripheral Component Interconnect Express - PCIe). For example, a cryptographic processor of a PCIe endpoint (such as a peripheral) may take a measurement (e.g., computing a hash value) of a code object on the device prior to executing the code object. This measurement may be placed in a register that is accessible to another component, such as a host operating system across a PCIe bus for interrogation. The host operating system may utilize an interconnect protocol, such as a PCIe protocol to access the measurement. These measurements may be consumed by a Trusted Platform Manager or other components of a host system that may verify the measurements.

  • 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.

  • Patent number: 11048626
    Abstract: Systems, apparatuses and methods may provide for technology that detects a misalignment condition, wherein the misalignment condition includes a memory map being misaligned with a granularity of a register, automatically appends a protected range to the memory map, wherein the protected range eliminates the misalignment condition, and defines an operational characteristic of the memory map via the register. In one example, the protected range is a non-existent memory (NXM) range appended via a source address decoder (SAD) rule, the register is a memory type range register (MTRR), and the operational characteristic is a cache characteristic.
