I recenly wrote a patch (with some help from Andreas) to a allow for gamma adjustment of the video overlay. It adds the XV_GAMMA attribute. The current patch works, but I'm not sure I'm programming the registers right. Could someone with databooks verify how they should be programmed? The relevant gamma table is in radeon_video.c. I asked ati about it, but I haven't heard anything back as of yet. I have a patch against DRI cvs here: http://www.botchco.com/alex/radeon/xv_and_gamma/gamma_v3.diff
Also according to the source r100 chips can only adjust the lower four and upper 2 gamma registers (which I assume map to points on the gamma curve). r200 can adjust all 18. The current code adjusts all 18 no matter which core is being used. will this cause a problem? I haven't seen any problems yet with my test systsm (m6 and 9200), however, the radeon video code in mplayer sets up the default gamma curves for them (r100 vs. r200) separately. Any ideas are appreciated. Alex __________________________________ Do you Yahoo!? Protect your identity with Yahoo!
