Bug 11700

Created attachment 10843 [details]
xorg log when the new 3D driver is activated

this the log when it fails (DRM init error resulting in no direct rendering)

Created attachment 10844 [details]
xorg configuration file

contains the general config (new 3D enabled, and EXA enabled)
I'll check if switching from EXA to XXA does something for me...

xorg log when using legacy 3D - direct rendering works

xorg log when having XXA enabled instead

still cannot init DRM when new memory manager is used

Is the X server using libdrm.so.2 built from GIT?

No, xorg-server was build from the normal gentoo ebuild (version 1.3.0.0). Actually I don't have a good GIT-ebuild to do the job (and I really don't want to update the whole system to bleading edge versions).

Shouldn't matter, just make sure it (specifically the libdri.so module) picks up the libdrm.so.2 built from GIT at runtime.

Ah yes, could the problem be related to this commit?
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=commit;h=1e169be25b2e4ab34afd4b8ae8ae0041f6069125

What I have done is renaming the libdrm.so.2.3.0 to libdrm.so.2.3.1 (correcting the various symlinks) and then rebuilding xf86-video-i810 (ebuild name for the intel xorg driver). AFAIK the make process checks for the libdrm version number, correct?
Maybe renaming the lib doesn't do the trick...

What I have done:
1) Shutting down the gdm login manager (-> Xorg shutdown)
2) Removing i195 and drm kernel module
3) Building from GIT
4) Renaming lib and correcting symlinks
5) running ldconfig
6) Building intel driver from GIT
7) Updating kernel module dependencies (because of the drm kernel module)
8) Starting login manager (-> Xorg startup -> loading i915 and drm kernel module)

How do I make really sure that libdri links to the correct file?

What does

ldd /path/to/libdri.so | grep drm

say? Assuming it points at the right symlink, does that point to the correct file (still)?

ldd /usr/lib/xorg/modules/extensions/libdri.so | grep drm:
libdrm.so.2 => /lib/libdrm.so.2 (0xb7f98000)

And this is strange, there are libdrm libraries in both /lib and /usr/lib

ls -l /lib/libdrm*:
-rwxr-xr-x 1 root root    768 2007-06-02 15:18 /lib/libdrm.la
lrwxrwxrwx 1 root root     15 2007-06-02 15:18 /lib/libdrm.so -> libdrm.so.2.3.0
lrwxrwxrwx 1 root root     15 2007-06-02 15:18 /lib/libdrm.so.2 -> libdrm.so.2.3.0
-rwxr-xr-x 1 root root 114308 2007-06-02 15:18 /lib/libdrm.so.2.3.0

ls -l /usr/lib/libdrm*:
-rw-r--r-- 1 root root   772 2007-07-23 16:55 /usr/lib/libdrm.la
lrwxrwxrwx 1 root root    15 2007-07-23 17:29 /usr/lib/libdrm.so -> libdrm.so.2.3.1
lrwxrwxrwx 1 root root    15 2007-07-23 17:29 /usr/lib/libdrm.so.2 -> libdrm.so.2.3.1
-rwxr-xr-x 1 root root 34812 2007-07-23 16:55 /usr/lib/libdrm.so.2.3.1

Hmm... going to check this...

OK, here we go:

I removed the libdrm files from /lib and also from /usr/lib and recompiled everything:
libdrm
drm kernel module
mesa
xorg-server
xf86-video-i810 (after renaming libdrm.so.2.3.0)

Now libdri.so links to /usr/lib/libdrm.so.2 and the X-server starts normally with the new 3D driver activated. glxinfo reports that direct rendering is on.

BUT glxgears won't work (log attached) and starting quake3 locks up the system to bad I can only use magic sysrq to restart it (vt switch won't work).

Any ideas?

xorg log when linked with correct libdrm.so

and it still crashes...

Created attachment 10860 [details]
kernel log when executing glxinfo and glxgears

I enabled debug in the drm module and started a failsafe session in gdm:
1) run glxinfo
2) run glxgears
3) switch to VT
4) get kernel log and shutdown X

The bug seems to be fixed by my latest GIT upgrade from yesterday.
Updated:
xf86-video-intel
libdrm
drm kernel module
mesa

I think it's unnecessary to do a bisect to find the commit that solves this for me. ;-)
