摘要： Methods and apparatus for restricted deployment of targeted processor firmware updates. During a patch enabling per-work flow, service entitlement license information comprising one of more service entitlements is generated and provisioned on one or more computing platforms. A restricted deployment microcode (uCode) update release (aka uCode patch) targeted for platforms having CPUs and/or XPUs with certain part identifier is sent to the one or more platforms. Run-time software and/or firmware on the platforms are executed to access the provisioned service entitlement license information, which is used to authentic and verify the restricted deployment uCode update release using a service entitlement having a part identifier associated with the platform's CPU. In one solution, authentication is performed using a hash-matching scheme and verification is used to verify the platform is properly licensed to load uCode included in the restricted deployment microcode (uCode) update release into the CPU.

摘要： A multiple switch assembly acts as an input device for computers. The switch assembly is comprised of a first input device which defines a circumference. A second input device is positioned within the circumference of the first input device. An interface is connected to the first input device and the second input device for producing output signals responsive to the first and second input devices. A portable computer utilizing such an input device is also disclosed.

摘要： In one embodiment the apparatus is a micro-page table engine that includes logic that is capable of receiving a memory page request for a page in global memory address space. The apparatus also includes a translation lookaside buffer (TLB) that is capable of storing one or more memory page address translations. Additionally, the apparatus also has a page miss handler capable of performing a micro physical address lookup in a page miss handler tag table in response to the TLB not storing the memory page address translation for the page of memory referenced by the memory page request. The apparatus also includes memory management logic that is capable of managing the page miss handler tag table entries.

摘要： An apparatus, method, machine-readable medium, and system are disclosed. In one embodiment the apparatus is a micro-page table engine that includes logic that is capable of receiving a memory page request for a page in global memory address space. The apparatus also includes a translation lookaside buffer (TLB) that is capable of storing one or more memory page address translations. Additionally, the apparatus also has a page miss handler capable of performing a micro physical address lookup in a page miss handler tag table in response to the TLB not storing the memory page address translation for the page of memory referenced by the memory page request. The apparatus also includes memory management logic that is capable of managing the page miss handler tag table entries. The micro-page table engine allows the TLB to be an agent that determines whether data in a two-level memory hierarchy is in a hot region of memory or in a cold region of memory. When data is in the cold region of memory, the micro-page table engine fetches the data to the hot memory and a hot memory block is then pushed out to the cold memory area.
