Description TeF 2009-04-02 10:30:38 UTC 
Xorg can't enable drm anymore with the new kernel, which disables about any hw
accelled rendering (kde4 is dogslow). There are some messages in dmesg and
Xorg.log, I'll attach them.

Reproducible: Always

Comment 6 Rafał Mużyło 2009-04-02 13:31:15 UTC 
There's an interesting part in your log:
(II) RADEON(0): XAA Render acceleration unsupported on Radeon 9500/9700 and newer. Please use EXA instead.
(II) RADEON(0): Render acceleration disabled
(II) RADEON(0): num quad-pipes is 1
(**) RADEON(0): Option "XaaNoOffscreenPixmaps" "True"
(II) RADEON(0): Using XFree86 Acceleration Architecture (XAA)

Any comment ?

If I add [Option         "AccelMethod"   "EXA"] in Section "Device" of xorg.conf , the information changed like following:
-------------------------------------------------------------------------------------------------------
#grep -i acceleration /var/log/Xorg.0.log
(**) RADEON(0): Using EXA acceleration architecture
(II) RADEON(0): Render acceleration enabled for R300/R400/R500 type cards.
(II)         Composite (RENDER acceleration)
(II) RADEON(0): Acceleration enabled
Comment 11 Rafał Mużyło 2009-04-02 18:23:00 UTC 
There's one more option, you may find useful:
"AccelDFS" "true"
AFAIK, it's a default on PCI and PCI-E, but not
on AGP.

That's indeed the first bug to fix.

Pretty useless to change any of these options if DRM is broken in the kernel.

@Tef, please install x11-base/x11-drm-9999 from the x11 overlay (you should copy it over into a local overlay, otherwise you'll have to update a bunch of unrelated libs).

Make sure you have all DRM stuff disabled in your kernel so that the x11-drm ebuild is able to build new modules for it.

Thanks

Thanks for your advice.I emerge the  x11-base/x11-drm-9999 form overlay but nothing changed.
Alex Deucher at freedesktop.org advise me booting with "nopat" option(one of kernel commmand line options).I try it and it works.When I booting with nopat option,DRI works well and drm is loaded fine,dmesg |grep drm shows no error messeng anymore.

Does this cause my problem ? How can I fix it complete? any advices for me ?

Yes, file a bug in FreeDesktop's bugzilla so that they can properly fix it. Please paste the url here so we can track whatever patches upstream commits.

Thanks

I have reported this bug  to  FreeDesktop's bugzilla several days ago. Here is  the  bug url
https://bugs.freedesktop.org/show_bug.cgi?id=21067
Comment 16 Rémi Cardona (RETIRED) gentoo-dev 2009-04-07 12:40:25 UTC 
Alright, let's track the bug upstream then.

Thanks
