    Abstract: Technologies disclosed herein provide an apparatus comprising a fuse controller coupled to an aggregator. The fuse controller includes a plurality of fuses for storing a unique identifier of a device and a first secured value of a first password associated with the unique identifier. The aggregator is to receive the unique identifier and the first secured value from the fuse controller, send the unique identifier to an unlock host, receive a second password from the unlock host, compute a second secured value of the second password using a security function, and unlock one or more privileged features on the device based on the first secured value corresponding to the second secured value. In a specific embodiment, the first secured value corresponds to the second secured value if the first password is equivalent to the second password.

    Abstract: A method and apparatus is disclosed herein for performing write-only inter processor reset synchronization. In one embodiment, the processing unit comprises: a communication unit to transmit information to the second processing unit; memory to store reset synchronization information and message information; and processing logic to perform write-only reset synchronization between itself and the second processing unit based on bit indications set in the memory.

    Abstract: A repair engine for a computing platform is separate from the repeatedly-rewritten storage components for software and firmware. For example, the repair engine may reside in ROM or hardware logic. Through dedicated connections to one or more controllers, the repair engine detects when any of the platform's dual-role ports (e.g., on-the-go USB ports) is connected to a host device. The repair engine responds by opening firmware-independent communication with the host device and supporting the downloading and execution (DnX) of a firmware image from the host. Because the communication is initiated independently of the firmware, even a catastrophic firmware failure is repairable without requiring a user to identify and use a specially modified port.

    Abstract translation: 用于计算平台的修复引擎与用于软件和固件的重复重写的存储组件分开。 例如，修复引擎可以驻留在ROM或硬件逻辑中。 通过与一个或多个控制器的专用连接，修复引擎检测何时平台的任何双重角色端口（例如，移动USB端口）连接到主机设备。 修复引擎通过打开与主机设备的固件无关的通信来响应，并支持来自主机的固件映像的下载和执行（DnX）。 由于通信是独立于固件启动的，即使是灾难性的固件故障也是可修复的，无需用户识别和使用特殊修改的端口。

    Abstract: A hardware platform includes a nonvolatile storage device that can store system firmware as well as code for the primary operating system for the hardware platform. The hardware platform includes a controller that determines the hardware platform lacks functional firmware to boot the primary operating system from the storage device. The controller accesses a firmware image from an external interface that interfaces a device external to the hardware platform, where the external device is a firmware image source. The controller provisions the firmware from the external device to the storage device and initiates a boot sequence from the provisioned firmware.
