Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 9/30

US Classification:

712229, 712215

Abstract:

A processing system features a first processing core to operate in a first node, a second processing core to operate in a second node, and random access memory (RAM) responsive to the first and second processing cores. The processing system also features control logic to perform operations such as (a) automatically updating a resident set size (RSS) counter to correspond to the RSS for the thread on the first node in response to allocation of a page frame for a thread in the first node, and (b) using the RSS counter to predict migration overhead when determining whether the thread should be migrated from the first processing core to the second processing core. Other embodiments are described and claimed.

International Classification:

G06F017/60
H04L009/00

US Classification:

705059000, 380200000

Abstract:

A system and method for managing digital rights. The method includes receiving a Universal Resource Identifier (URI). The URI is used to identify a location for a user selected digital media item. The digital media item is to be played in a local area network (LAN). The selected digital media item is retrieved from a content server over a network connection. If the selected digital media item is encrypted, a license to decrypt the selected media item is obtained. Access to the license is based on a plurality of access rules. The plurality of access rules are based on the terms of the license. The plurality of access rules may also include personal owner rules. If a request for the license adheres to the access rules, the license is received via a secure out of band transfer and the selected digital media item is decrypted for playback via one or more media rendering devices.

Appl. No.:

10/768251

Inventors:

Daniel Baumberger - Cornelius OR, US

International Classification:

G06F013/00

US Classification:

719327000

Abstract:

By loading deprivileged drivers, such as third party supplied drivers, into a virtual machine under control of a virtual machine monitor, a kernel may be protected from faults that arise on those drivers. When a fault is detected, the system may transition from a guest mode, wherein the third party drivers operate through the virtual machine monitor, to a monitor mode, wherein the monitor takes control and provides appropriate correction if possible. In some cases, the virtual machine monitor may simply destroy and restart the virtual machine. In such cases, it may be possible to overcome the faults without crashing the entire operating system.

Appl. No.:

10/802198

Inventors:

Daniel Baumberger - Cornelius OR, US

International Classification:

H04L012/56

US Classification:

370389000

Abstract:

A method, apparatus and system enable improved demultiplexing in a virtual machine (“VM”) environment. Typically, guest physical addresses of the VMs are mapped to the physical page addresses of the host, thus requiring incoming packets to be copied from the host's direct memory access (“DMA”) buffer to the destination VM's buffer. Embodiments of the present invention unmap the guest physical address of the VMs from the physical page address of the host, thus freeing up a “pool” of pages to be mapped to the destination VM as necessary. Thus, by disassociating the guest physical address from the physical page address, embodiments of the invention eliminate the need for copying incoming packets from one buffer to another.

International Classification:

G06F 9/455
G06F 9/30

US Classification:

712208, 718 1, 712E09028

Abstract:

Embodiments of apparatuses, methods, and systems for modifying the behavior of a guest installed to run within a VM are disclosed. In one embodiment, an apparatus includes virtualization logic, first storage, second storage, decode logic, and multiplexing logic. The virtualization logic is to provide a mode in which to operate a virtual machine. The first storage is to store a first plurality of micro-instructions to control the apparatus. The second storage is to store a second plurality of micro-instructions to control the apparatus. The decode logic is to decode a macro-instruction into one of a first plurality and a second plurality of micro-instructions. The multiplexing logic is to cause the macro-instruction to be decoded into the second plurality of micro-instructions instead of the first plurality of micro-instructions only when issued from the virtual machine.
