In some embodiments, a PPM interface for a computing platform may be provided with functionality to facilitate, to an OS through the PPM interface, firmware performance data.

Computing performance and power management with firmware performance data structure

An embodiment of a semiconductor package apparatus may include technology to determine respective priority levels for one or more boot time events, determine an amount of execution time for the one or more boot time events, and automatically adjust a timer based on the amount of execution time and the priority levels for the one or more boot time events. Other embodiments are disclosed and claimed.

Dynamic timer adjustment to improve performance and inhibit livelock conditions

In some embodiments, the invention involves partitioning resources of a manycore platform for simultaneous use by multiple clients, or adding/reducing capacity to a single client. Cores and resources are activated and assigned to a client environment by reprogramming the cores' route tables and source address decoders. Memory and I/O devices are partitioned and securely assigned to a core and/or a client environment. Instructions regarding allocation or reallocation of resources is received by an out-of-band processor having privileges to reprogram the chipsets and cores. Other embodiments are described and claimed.

System and method for supporting metered clients with manycore

In one embodiment, the present invention includes a method to establish a secure pre-boot environment in a computer system and performs at least one secure operation in the secure environment. In one embodiment, the secure operation may be storage of a secret in the secure pre-boot environment.

Providing a secure execution mode in a pre-boot environment

Technologies for media protection policy enforcement include a computing device having multiple operating systems and a data storage device partitioned into a number of regions. During execution of each of the operating systems, a policy enforcement module may intercept media access requests and determine whether to allow the media access requests based on platform media access policies. The media access policies may allow requests based on the identity of the executing operating system, the region of the data storage device, or the requested storage operation. Prior to loading a selected operating system, a firmware policy enforcement module may determine a region of the disk storage device to protect from the selected operating system. The firmware policy enforcement module may configure the data storage device to prevent access to that region. The media access policies may be stored in one or more firmware variables. Other embodiments are described and claimed.

Media protection policy enforcement for multiple-operating-system environments

In some embodiments, a PPM interface may be provided with functionality to facilitate to an OS memory power state management for one or more memory nodes, regardless of a particular platform hardware configuration, as long as the platform hardware is in conformance with the PPM interface.

Computing platform interface with memory management

Methods, systems and computer program products are disclosed for enhanced system boot processing that is faster to launch an operating system, as certain devices such as user input hardware devices may not be initialized unless it is determined that a user-interruption to the boot process is likely. That is, although an interface for the devices is exposed, no initialization occurs unless a call to the interface occurs. Other embodiments are described and claimed.

Method for reducing platform boot times by providing lazy input/output abstractions

In one embodiment, the present invention includes a method to establish a secure pre-boot environment in a computer system; and perform at least one secure operation in the secure environment. In one embodiment, the secure operation may be storage of a secret in the secure pre-boot environment.

Supporting metered clients with manycore through time-limited partitioning

When transitioning from sleep mode to active mode, a processing system loads first stage resume content and second stage resume content into a volatile memory of the processing system. The first stage resume content may contain contextual data for a first program that was in use before the processing system transitioned to sleep mode. The second stage resume content may contain contextual data for another program that was in use before the processing system transitioned to sleep mode. The processing system may provide a user interface for the first program before all of the second stage resume content has been loaded into the volatile memory. Other embodiments are described and claimed.

Method and apparatus for quick resumption of a processing system with volatile memory

A method to qualify access to a block storage device via augmentation of the device's controller and firmware flow. The method employs one or more block exclusion vectors (BEVs) that include attributes specifying allowed access operations for corresponding block address ranges. Logic in accordance with the BEVs is programmed into the controller for the block storage device, such as a disk drive controller for a disk drive. In response to an access request, a block address range corresponding to the storage block(s) requested to be accessed is determined. Based on the BEV entries, a determination is made to whether the determined logical block address range is covered by a corresponding BEV entry. If so, the attributes of the BEV are used to determine whether the access operation is allowed.
