Abstract:
In one embodiment, a processor has multiple cores to execute threads. The processor further includes a power control logic to enable entry into a turbo mode based on a comparison between a threshold and value of a counter that stores a count of core power and performance combinations that identify turbo mode requests of at least one of the threads. In this way, turbo mode may be entered at a utilization level of the processor that provides for high power efficiency. Other embodiments are described and claimed.
Abstract:
An antivirus (AV) application specifies a fault handler code image, a fault handler manifest, a memory location of the AV application, and an AV application manifest. A loader verifies the fault handler code image and the fault handler manifest, creates a first security domain having a first security level, copies the fault handler code image to memory associated with the first security domain, and initiates execution of the fault handler. The loader requests the locking of memory pages in the guest OS that are reserved for the AV application. The fault handler locks the executable code image of the AV application loaded into guest OS memory by setting traps on selected code segments in guest OS memory.
Abstract:
Secure authentication to a remote application operating on a remote server across a network includes detecting a login associated with the remote application; and in response to the detected login, offloading the login process to an isolated execution environment configured to receive a login request message from the browser application; identify confidential information stored in the secure memory storage and associated with the remote application; populate the login request message with the identified confidential data; transmit the populated login request message to the remote application; receive a login response message from the remote application upon successful login; and transmit the login response message to the browser application, wherein only the isolated execution environment can read and write to the secure memory storage.
Abstract:
Systems and methods of operating a computing system may involve identifying a plurality of state values, wherein each state value corresponds to a computing thread associated with a processor. An average value can be determined for the plurality of state values, wherein a determination may be made as to whether to grant a frequency boost request based at least in part on the average value.

Abstract:
A request associated with a particular cache record is generated to be sent to a system component associated with a cache bank over an interconnect. A wake-warn signal is sent over a dedicated wake-warn channel to indicate to the system component that the request is to arrive. Wake-warn signals cause a disabled clock to be ungated to an enabled state. The request is then sent to the system component.

Abstract:
A manageability engine or adjunct processor on a computer platform may receive a request for activation and use of features embedded within that platform from a service provider authorized by the manageability engine's manufacturer. The manageability engine may initiate a request for authority through the service provider to a permit server. The permit server may provide, through the service provider, proof of the service provider's authority, together with a certificate identifying the service provider. Then the manageability engine may enable activation of the features on the platform coupled to the manageability engine, but only by the one particular service provider who has been authorized.
