20090248983 | TECHNIQUE TO SHARE INFORMATION AMONG DIFFERENT CACHE COHERENCY DOMAINS - A technique to enable information sharing among agents within different cache coherency domains. In one embodiment, a graphics device may use one or more caches used by one or more processing cores to store or read information, which may be accessed by one or more processing cores in a manner that does not affect programming and coherency rules pertaining to the graphics device. | 10-01-2009 |
20100031268 | Thread ordering techniques - Techniques are described that can be used to ensure ordered computation and/or retirement of threads in a multithreaded environment. Threads may contain bundled instances of work, each with unique ordering restrictions relative to other instances of work packaged in other threads in the system. When applied to 3D graphics, video and image processing domains allow unrestricted processing of threads until reaching their critical sections. Ordering may be required prior to executing critical sections and beyond. | 02-04-2010 |
20100235320 | ENSURING COHERENCE BETWEEN GRAPHICS AND DISPLAY DOMAINS - A platform may comprise a core coherency domain, graphics coherency domain and a non-coherent domain. A graphics acceleration unit (GAU) of the graphics coherency domain may generate data units from an application and the data units may comprise display data units. The GAU may annotate the display data units with an annotation value before flushing the display data units to an on-die cache. The GAU may identify modified display data units among the display data units stored in the on-die cache and issue flush commands to cause flushing of the modified display data units from the on-die cache to a main memory. The display engine of the non-coherent domain may use the modified display data units stored in the main memory to render a display on a display device. | 09-16-2010 |
20120200585 | TECHNIQUE TO SHARE INFORMATION AMONG DIFFERENT CACHE COHERENCY DOMAINS - A technique to enable information sharing among agents within different cache coherency domains. In one embodiment, a graphics device may use one or more caches used by one or more processing cores to store or read information, which may be accessed by one or more processing cores in a manner that does not affect programming and coherency rules pertaining to the graphics device. | 08-09-2012 |
20120233439 | Implementing TLB Synchronization for Systems with Shared Virtual Memory Between Processing Devices - Page faults arising in a graphics processing unit may be handled by an operating system running on the central processing unit. In some embodiments, this means that unpinned memory can be used for the graphics processing unit. Using unpinned memory in the graphics processing unit may expand the capabilities of the graphics processing unit in some cases. | 09-13-2012 |
20120236010 | Page Fault Handling Mechanism - Page faults arising in a graphics processing unit may be handled by an operating system running on the central processing unit. In some embodiments, this means that unpinned memory can be used for the graphics processing unit. Using unpinned memory in the graphics processing unit may expand the capabilities of the graphics processing unit in some cases. | 09-20-2012 |
20130007751 | METHOD AND SYSTEM FOR SAFE ENQUEUING OF EVENTS - A method and system to facilitate a user level application executing in a first processing unit to enqueue work or task(s) safely for a second processing unit without performing any ring transition. For example, in one embodiment of the invention, the first processing unit executes one or more user level applications, where each user level application has a task to be offloaded to a second processing unit. The first processing unit signals the second processing unit to handle the task from each user level application without performing any ring transition in one embodiment of the invention. | 01-03-2013 |
