摘要： An electronic device is described herein. The electronic device may include a page walker module to receive a page request of a graphics processing unit (GPU). The page walker module may detect a page fault associated with the page request. The electronic device may include a controller, at least partially comprising hardware logic. The controller is to monitor execution of the page request having the page fault. The controller determines whether to suspend execution of a work item at the GPU associated with the page request having the page fault, or to continue execution of the work item based on factors associated with the page request.

摘要： Methods and systems may provide for storing a set of post-synchronization operations to a graphics memory and sending a flush marker to a graphics pipeline. Additionally, the set of post-synchronization operations may be processed in response to the flush marker exiting the graphics pipeline. In one example, the set of post-synchronization operations includes one or more atomic operations. Moreover, the set of post-synchronization operations may be obtained from an inline portion of an atomics command.

摘要： Methods and apparatus are disclosed for efficient TLB (translation look-aside buffer) shoot-downs for heterogeneous devices sharing virtual memory in a multi-core system. Embodiments of an apparatus for efficient TLB shoot-downs may include a TLB to store virtual address translation entries, and a memory management unit, coupled with the TLB, to maintain PASID (process address space identifier) state entries corresponding to the virtual address translation entries. The PASID state entries may include an active reference state and a lazy-invalidation state. The memory management unit may perform atomic modification of PASID state entries responsive to receiving PASID state update requests from devices in the multi-core system and read the lazy-invalidation state of the PASID state entries. The memory management unit may send PASID state update responses to the devices to synchronize TLB entries prior to activation responsive to the respective lazy-invalidation state.
