I just finished up a patch that adds overlay gamma adjustment support to the radeon driver. This patch adds two new XV attributes: XV_COLORSPACE and XV_GAMMA.
XV_COLORSPACE allows you to choose between the BT.601 (0, default) and BT.709 (1) color standards. XV_GAMMA lets you adjust the gamma of the overlay to 8 presets: 0 - gamma 1.0, default 1 - 0.85 2 - 1.1 3 - 1.2 4 - 1.45 5 - 1.7 6 - 2.2 7 - 2.5 Please let me know if you have any suggestions or find any bugs with this code. The patch is against DRI cvs, but should apply pretty easily to xfree86 or gatos as well.
