Abstract:
In one embodiment, a cache memory includes entries each to store a ring level identifier, which may indicate a privilege level of information stored in the entry. This identifier may be used in performing read accesses to the cache memory. As an example, a logic coupled to the cache memory may filter an access to one or more ways of a selected set of the cache memory based at least in part on a current privilege level of a processor and the ring level identifier of the one or more ways. Other embodiments are described and claimed.
Abstract:
Embodiments of an apparatus for controlling cache occupancy rates are presented. In one embodiment, an apparatus comprises a controller and monitor logic. The monitor logic determines a monitored occupancy rate associated with a first program class. The first controller regulates a first allocation probability corresponding to the first program class, based at least on the difference between a requested occupancy rate and the first monitored occupancy rate.
Abstract:
A cutting tool includes a body having a forward end and a rearward end. The forward end includes an insert-receiving pocket with a threaded hole having a center axis. The cutting tool further includes a cutting insert with a countersunk bore with a center axis. The cutting tool includes an error proofing feature for preventing the cutting insert to be properly mounted in an insert-receiving pocket when an offset distance between the center axis of the threaded hole of the insert-receiving pocket and the center axis of the countersunk bore of the cutting insert is greater than a predetermined percentage of the outer diameter of the threaded screw.
Abstract:
In one embodiment, the present invention includes a method for associating a first priority indicator with first data stored in a first entry of a cache memory to indicate a priority level of the first data, and updating a count value associated with the first priority indicator. The count value may then be used in determining an appropriate cache line for eviction. Other embodiments are described and claimed.
Abstract:
In one embodiment, the present invention includes a page fault handler to create page table entries and TLB entries in response to a page fault, the page fault handler to determine if a page fault resulted from a stack access, to create a superpage table entry if the page fault did result from a stack access, and to create a TLB entry for the superpage. Other embodiments are described and claimed.
Abstract:
In one embodiment, the present invention includes a method for handling a registration message received from a host processor, where the registration message delegates a poll operation with respect to a device from the host processor to another component. Information from the message may be stored in a poll table, and the component may send a read request to poll the device and report a result of the poll to the host processor based on a state of the device. Other embodiments are described and claimed.
Abstract:
Methods and apparatus for control of On-Die System Fabric (OSF) blocks are described. In one embodiment, a shadow address corresponding to a physical address may be stored in response to a user-level request and a logic circuitry (e.g., present in an OSF) may determine the physical address from the shadow address. Other embodiments are also disclosed.
Abstract:
In one embodiment, the present invention includes a method for incrementing a counter value associated with a cache line if the cache line is inserted into a first level cache, and storing the cache line into a second level cache coupled to the first level cache or a third level cache coupled to the second level cache based on the counter value, after eviction from the first level cache. Other embodiments are described and claimed.
Abstract:
A method and apparatus for throttling power and/or performance of processing elements based on a priority of software entities is herein described. Priority aware power management logic receives priority levels of software entities and modifies operating points of processing elements associated with the software entities accordingly. Therefore, in a power savings mode, processing elements executing low priority applications/tasks are reduced to a lower operating point, i.e. lower voltage, lower frequency, throttled instruction issue, throttled memory accesses, and/or less access to shared resources. In addition, utilization logic potentially trackes utilization of a resource per priority level, which allows the power manager to determine operating points based on the effect of each priority level on each other from the perspective of the resources themselves. Moreover, a software entity itself may assign operating points, which the power manager enforces.
Abstract:
In one embodiment, the present invention includes a translation lookaside buffer (TLB) having storage locations each including a priority indicator field to store a priority level associated with an agent that requested storage of the data in the TLB, and an identifier field to store an identifier of the agent, where the TLB is apportioned according to a plurality of priority levels. Other embodiments are described and claimed.
