Description P.L.Hayes 2006-06-19 20:52:13 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 bug has been around for a long time (certainly pre-7.1) but I only recently
got around to filing it as https://bugs.gentoo.org/show_bug.cgi?id=137184 and
Joshua Baergen requested that I file it here too.

Already fixed in 6.6.1.
