Abstract
According to one aspect of the invention, a query request is received from a client application at a multithreaded graphics framework. The multithreaded graphics framework including a first thread configured to place graphics commands from the client application into a command queue and a second thread configured to dispatch the graphics commands from the command queue to a graphics processing unit (GPU) for execution. In response to the query request, the first thread is configured to store query information of the query request in a query block of memory that is separated from the command queue and notifying the second thread. In response to the notification, the second thread is configured to issue a query command to the GPU based on the query information retrieved from the query block, prior to dispatching remaining graphics commands pending in the command queue.
