Methods and apparatus to manage throttling in computing environments are described herein. One example method may include receiving an indication that a first memory module has reached a temperature and remapping information from the first memory module to a second memory in response to the received indication. Other methods are described.
摘要:
A method, apparatus, system, and computer program product for multi-owner deployment of firmware images. The method includes obtaining a signed firmware image that comprises a first code module signed by a first code owner and a second code module signed by a second code owner. The method further includes obtaining an updated first code module comprising updated code for the first code module, verifying that the updated first code module is signed by the first code owner, and updating the signed firmware image with the updated first code module in response to verifying that the updated first code module is signed by the first code owner. The signed firmware image may further comprise an access control list that authorizes updates to the first code module by the first code owner and updates to the second code module by the second code owner.
摘要:
A software-defined radio (SDR) capability may be provided in a general purpose, many core processing system by sequestering one or more partitions running on one or more cores and instantiating a communications capability by having discrete SDR functions performed by the sequestered partitions. Each SDR module embodied in a sequestered partition may be independently upgraded without modifying the hardware of the underlying processing system. By executing SDR modules in cores not accessible by application programs and/or an operating system (OS), a better Quality of Service (QoS) may be provided for wireless communications on the general purpose, multi-core processing system. An embodiment comprises isolating a core of a many core processing system as a sequestered partition, loading a software-defined radio module onto the core, and executing the software-defined module to implement wireless communications.
摘要:
Radio frequency identification (RFID) tags embedded in processors within a computing system provide a separate communication path to other components of the computing system during initialization processing, apart from the system interconnect. Upon powering up, each processor causes its RFID tag to broadcast data regarding the processor's interconnect location and initialization status. A RFID receiver senses the RFID tags in the Platform Control Hub (PCH), and each processor's interconnect location and initialization status data is stored in registers within the PCH. During system initialization processing, the BIOS accesses these PCH registers to obtain the processor's data. The interconnect location and initialization status data is used by the BIOS to select the optimal routing table and configure the virtual network within the computing system based on the optimal routing table and the RFID tag data, without interrogating each processor individually over the system interconnect.

Enhancing locality in a security co-processor module of a computing system may be achieved by including one or more additional attributes such as geographic location, trusted time, a hardware vendor string, and one or more environmental factors into an access control space for machine mode measurement of a computing system.

摘要:
A method and apparatus for improving the resume time of a platform. In one embodiment of the invention, the context of the platform is saved prior to entering an inactive state of the platform. When the platform is switched back to an active state, it reads the saved context and restores the platform to its original state prior to entering the inactive state. In one embodiment of the invention, the platform determines whether it should compress the saved context before storing it in a non-volatile memory based on the operating condition of the platform. This allows the platform to select the optimum method to allow faster resume time of the platform.
摘要:
A method, apparatus, system, and computer program product for secure server system management. A payload containing system software and/or firmware updates is distributed in an on-demand, secure I/O operation. The I/O operation is performed via a secured communication channel inaccessible by the server operating system to an emulated USB drive. The secure communication channel can be established for the I/O operation only after authenticating the recipient of the payload, and the payload can be protected from access by a potentially-infected server operating system. Furthermore, the payload can be delivered on demand rather than relying on a BIOS update schedule, and the payload can be delivered at speeds of a write operation to a USB drive.
