tex-invalid

Description

This program does the test for the texture cache invalidation function. The eight cache regions have one-to-one correspondences to the eight texture objects. Each texture object uses only one dedicated region (for example, texobj0 uses cache0 and texobj1 uses cache1). Textured quads are rendered five times by using each texture object while image data in main memory is overwritten by other data after rendering each quad. You can control whether cache invalidation should be done before drawing the next quad and whether to reflect the overwritten image. As for the fifth quad, GXInvalidateTexAll is called and so always reflects the overwritten image.
