Abstract
A method and apparatus in a data processing system for asynchronous context switching. Requests of graphics processes are received to process graphics data for display in a queue in the graphics adapter. A current context is switched for a first graphics process to a new context for a second graphics process only in response to requests received in the queue. In this manner, the graphics adapter is able to continuously process commands in the queue instead of waiting for new commands to be sent after each context switch.
