Method of submitting graphics workloads and handling dropped workloads

摘要

Described herein are technologies related to performing of a preemption operation in graphics hardware. Particularly, the preemption operation includes tracking of unreported or dropped workload independent of workloads submitted to the graphics hardware.

主权项

1. A method of performing a pre-emption in graphics hardware, the method comprising:
receiving and loading of at least two workloads; processing the at least two workloads; interrupting the processing of the at least two workloads by processing of a high priority workload; tracking an unreported or dropped workload due to the processing of the high priority workload, wherein the tracking includes treating one of said at least two workloads that does not appear in a hardware context status report as the unreported or dropped workload; and determining whether a new workload is received and loaded, wherein the tracked unreported or dropped workload is re-queued after the new workload in response to the determination of receiving and loading of the new workload.
