Description PL Hayes 2006-06-18 09:53:00 UTC
The radeon man page says:

       Option "AGPMode" "integer"
              Set AGP data transfer rate.  (used only when DRI is enabled)
              1      -- x1 (default)
              2      -- x2
              4      -- x4
              8      -- x8
              others -- invalid

Setting the rate to "4" works as expected but when I set it to "8" in my xorg.conf for my radeon 9250, I get these messages in the log  

agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0
agpgart: X tried to set rate=x12. Setting to AGP3 x8 mode.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
agpgart: Putting AGP V3 device at 0000:02:00.0 into 8x mode

This isn't a new bug - it's not something that's suddenly appeared in xorg-7.x or kernel 2.6.x - I've just not gotten around to reporting it in the last year or so since it doesn't seem to be harmful and I don't really know which component is at fault.

I saw this too, with the r300 driver, but I just ignored it.
