摘要:
The invention provides a cache management system comprising in various embodiments pre-load and pre-own functionality to enhance cache efficiency in shared memory distributed cache multiprocessor computer systems. Some embodiments of the invention comprise an invalidation history table to record the line addresses of cache lines invalidated through dirty or clean invalidation, and which is used such that invalidated cache lines recorded in an invalidation history table are reloaded into cache by monitoring the bus for cache line addresses of cache lines recorded in the invalidation history table. In some further embodiments, a write-back bit associated with each L2 cache entry records when either a hit to the same line in another processor is detected or when the same line is invalidated in another processor's cache, and the system broadcasts write-backs from the selected local cache only when the line being written back has a write-back bit that has been set.

摘要:
A virtual environment manager (“VEM”) simplifies the usability of virtual machines and provides users with an enhanced design for creating and/or for managing virtual machines (“VMs”). For example, a user can select description information and management information to be included in descriptors and according to which a VEM will create and manage various VM environments for various host environments. The VEM automatically creates the VM environments and host environments by sending descriptor description information and data files associated with the description information to virtual machine monitors (VMMs), which create the VM environments according to the description information. A VEM at each host may manage VM environments executed by the VMM, according to the descriptor management information. Thus, a set of descriptors to create and manage a set of VMs for a home computer may be easily modified by a user to create and manage a set of VMs for a work or laptop computer.

According to an embodiment of the invention, a method for operating a data processing machine is described in which data about a state of the machine is written to a location in storage. The location is one that is accessible to software that may be written for the machine. The state data as written is encoded. This state data may be recovered from the storage according to a decoding process. Other embodiments are also described and claimed.
摘要:
Embodiments of apparatuses and methods for memory event notification are disclosed. In one embodiment, a processor includes address translation hardware and memory event hardware. The address translation hardware is to support translation of a first address, used by software to access a memory, to a second address, used by the processor to access the memory. The memory event hardware is to detect an access to a registered portion of memory.
摘要:
A system and method for BIOS flash attack protection and notification. A processor initialization module, including initialization firmware verification module may be configured to execute first in response to a power on and/or reset and to verify initialization firmware stored in non-volatile memory in a processor package. The initialization firmware is configured to verify the BIOS. If the verification of the initialization firmware and/or the BIOS fails, the system is configured to select at least one of a plurality of responses including, but not limited to, preventing the BIOS from executing, initiating recovery, reporting the verification failure, halting, shutting down and/or allowing the BIOS to execute and an operating system (OS) to boot in a limited functionality mode.
摘要:
A process is introduced that determines contour requirements from many factors. Based on the contour requirements, the process either generates at least one content-derived signature contour from either many content identifiers or at least one content-derived signature contour, or generates at least one optimized content-derived signature contour from contour-related data and either at least one content-derived signature contour or a derivation from at least one content-derived signature contour.
摘要:
In one embodiment, a semiconductor integrated code (SIC) may be provided in a binary format by a processor manufacturer. This SIC may include platform independent code of the processor manufacturer. Such code may include embedded processor logic to initialize the processor and at least one link that couples the processor to a memory, and embedded memory logic to initialize the memory. Other embodiments are described and claimed.

摘要:
A method, apparatus and system for improving usability of virtual machines is described. A console module on a VM host may continuously monitor incoming data (e.g., files and/or attachments) and make automatic determinations regarding how and/or whether to intercept, route, redirect and/or deliver the data (e.g., where to store files, when and/or whether to deliver the files, execute the files, etc.). Additionally, in one embodiment, a unification console may be provided to enhance the usability of the VM host. The unification console enables the user to view the VM host via a unified desktop interface while handling the underlying switching and/or interactions between VMs.
