Method, system, and computer program product for determining a structure of a graphics compositor tree
First Claim
1. A method of determining a structure of a compositor tree, comprising:
- (1) locating a downstream compositor of the compositor tree;
(2) counting a number of compositors coupled to said located downstream compositor; and
(3) ascertaining if a compositor of said counted number of compositors is a graphics pipeline.

Abstract
Compositors are identified in a manner that defines the position of the compositor in the compositor tree. Each compositor has its own “unique compositor identifier”. Starting at the most downstream compositor, it transmits its unique compositor identifier to all upstream compositors directly coupled to it. The upstream compositors receive the unique compositor identifier from the most downstream compositor. Each of the upstream compositors appends its unique compositor identifier to the unique compositor identifier received from the most downstream compositor to produce a “compositor tree compositor identifier”. The compositor tree compositor identifier identifies both the compositor and its position in the compositor tree. This enables an application to detect the structure of the compositor tree so that the application can determine a desired tiling configuration that exploits the structure of the compositor tree.

9. A system to determine a structure of a compositor tree, comprising:
-
a memory configured to store compositor tree compositor identifiers of compositors in the compositor tree; and a processor coupled to said memory, and configured to locate a downstream compositor of the compositor tree, to count a number of compositors coupled to said downstream compositor, and to ascertain if a compositor of said number of compositors coupled to said downstream compositor is a graphics pipeline. - View Dependent Claims (10, 11, 12)
