From: Aric Cyr <[email protected]> [WHY] When SubVP is active the HW cursor size is limited to 64x64, and anything larger will force composition which is bad for gaming on DCN3.2 if the game uses a larger cursor.
[HOW] If HW cursor is requested, typically by a fullscreen game, do not enable SubVP so that up to 256x256 cursor sizes are available for DCN3.2.
