Patent number: 9990206Abstract: In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.Type: GrantFiled: March 15, 2013Date of Patent: June 5, 2018Assignee: INTEL CORPORATIONInventors: Hong Wang, John Shen, Edward Grochowski, Richard Hankins, Gautham Chinya, Bryant Bigbee, Shivnandan Kaushik, Xiang Chris Zou, Per Hammarlund, Scott Dion Rodgers, Xinmin Tian, Anil Aggawal, Prashant Sethi, Baiju Patel, James Held

Patent number: 9875102Abstract: Embodiments of the invention provide a method of creating, based on an operating-system-scheduled thread running on an operating-system-visible sequencer and using an instruction set extension, a persistent user-level thread to run on an operating-system-sequestered sequencer independently of context switch activities on the operating-system-scheduled thread. The operating-system-scheduled thread and the persistent user-level thread may share a common virtual address space. Embodiments of the invention may also provide a method of causing a service thread running on an additional operating-system-visible sequencer to provide operating system services to the persistent user-level thread. Embodiments of the invention may further provide apparatus, system, and machine-readable medium thereof.Type: GrantFiled: December 21, 2016Date of Patent: January 23, 2018Assignee: Intel CorporationInventors: Gautham Chinya, Hong Wang, Prashant Sethi, Shivnandan Kaushik, Bryant Bigbee, John Shen, Richard Hankins, Xiang Zou, Baiju V.

Patent number: 9588771Abstract: In one embodiment, the present invention includes a method for directly communicating between an accelerator and an instruction sequencer coupled thereto, where the accelerator is a heterogeneous resource with respect to the instruction sequencer. An interface may be used to provide the communication between these resources. Via such a communication mechanism a user-level application may directly communicate with the accelerator without operating system support. Further, the instruction sequencer and the accelerator may perform operations in parallel. Other embodiments are described and claimed.Type: GrantFiled: March 8, 2013Date of Patent: March 7, 2017Assignee: Intel CorporationInventors: Hong Wang, John Shen, Hong Jiang, Richard Hankins, Per Hammarlund, Dion Rodgers, Gautham Chinya, Baiju Patel, Shiv Kaushik, Bryant Bigbee, Gad Sheaffer, Yoav Talgam, Yuval Yosef, James P.

Patent number: 8671275Abstract: A platform and method for secure handling of events in an isolated environment. A processor executing in isolated execution “IsoX” mode may leak data when an event occurs as a result of the event being handled in a traditional manner based on the exception vector. By defining a class of events to be handled in IsoX mode, and switching between a normal memory map and an IsoX memory map dynamically in response to receipt of an event of the class, data security may be maintained in the face of such events.Type: GrantFiled: August 26, 2010Date of Patent: March 11, 2014Assignee: Intel CorporationInventors: Francis X. McKeen, Lawrence O. Smith, Benjamin Crawford Chaffin, Michael P. Cornaby, Bryant Bigbee

Patent number: 8516483Abstract: Operating system services are transparently triggered for thread execution resources (“sequencers”) that are sequestered from view of the operating system. A “surrogate” thread that is managed by, and visible to, the operating system is utilized to acquire OS services on behalf of a sequestered sequencer. Multi-shred contention for shred-specific resources may thus be alleviated. Other embodiments are also described and claimed.Type: GrantFiled: May 13, 2005Date of Patent: August 20, 2013Assignee: Intel CorporationInventors: Gautham Chinya, Hong Wang, Richard A.
