 |
|
The ATI Radeon cards in the various PowerBook G4s (except for the latest line) can now be used with 3D acceleration, thanks to MrCooper (mdaenzer)! 
Instructions:
Get the DRI CVS trunk with:
cvs -d:pserver:anonymous@cvs.dri.sourceforge.net:/cvsroot/dri login
<Press enter>
cvs -z4 -d:pserver:anonymous@cvs.dri.sourceforge.net:/cvsroot/dri co xc
This will download approx. 90MB files onto your hard disk. Then, compile it with:
| Code: | cd xc
ln -s xc XFree40
mkdir build
cd build
lndir -silent -ignorelinks ../XFree40
|
Then, you will need to edit the host.def file, located in xc/config/cf/host.def.
Change it to:
| Code: | /*
* Set this for each DRI branch. It will be appended to the XFree86 version
* information.
*/
#define XFree86CustomVersion "DRI trunk"
#define DefaultGcc2AxpOpt -O2 -mcpu=ev6
#define DefaultGcc2PpcOpt -O2 -pipe -mpowerpc-gfxopt -mmultiple -mstring -mnew-mnemonics -ffast-math -fsigned-char
#define DefaultGcc2i386Opt -O2
#if defined(AlphaArchitecture)
# define LibraryCDebugFlags -O2 -mcpu=ev6
#elif defined(PpcArchitecture)
# define LibraryCDebugFlags -O2 -pipe -mpowerpc-gfxopt -mmultiple -mstring -mnew-mnemonics -ffast-math -fsigned-char
#else
# define LibraryCDebugFlags -O2
#endif
#define BuildXFree86ConfigTools YES
#define XF86CardDrivers ati
#define DriDrivers radeon /* sis ffb */
#define GccWarningOptions -Wall -Wpointer-arith -Wstrict-prototypes \
-Wmissing-prototypes -Wmissing-declarations \
-Wnested-externs
#define DefaultCCOptions -ansi GccWarningOptions -pipe -g
#define NormalLibGlx NO
#define BuildXF86DRI YES
/* To do profiling of the dynamically loaded 'xyz_dri.so' object, turn
* this on.
* Use 'xc/lib/GL/makeprofile.sh' to make it work.
*/
/* #define GlxSoProf YES */
#ifdef GlxSoProf
# undef DefaultCCOptions
# define DefaultCCOptions -ansi GccWarningOptions -pipe -g -p
#endif
/* Optionally turn these on for debugging */
/* #define GlxBuiltInTdfx YES */
/* #define GlxBuiltInI810 YES */
/* #define GlxBuiltInMga YES */
/* #define GlxBuiltInR128 YES */
/* #define GlxBuiltInRadeon YES */
/* #define DoLoadableServer NO */
/* Optionally turn this on to change the place where you install the build.
* Warning: trailing blanks will cause build failures.
*/
/* #define ProjectRoot /usr/X11R6-DRI */
/* Optionally turn this on to force the kernel modules to build */
/* #define BuildXF86DRM YES */
#define XF86AFB NO
#define XnestServer NO
#define XVirtualFramebufferServer NO
/*
* Don't change anything below or the build will fail.
*/
#define BuildServersOnly YES
#define BuildLibrariesForXServers NO
#define BuildLibrariesForConfigTools NO
#define BuildXIE NO
#define BuildPexExt NO
#define XprtServer NO
#define SharedLibFont NO

Note: The optimizations on that are for G4. I have only tested it with a Titanium PowerBook G4, no L3 cache with an ATI Radeon M6 LY.
When you have edited your host.def, do:
| Code: | cd build/xc/
make World >& world.log & tail -f world.log
|
That will take about 1/2 hour to compile. When that is done, do a:
Then cd to build/xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel/, and:
| Code: | make -f Makefile.linux
|
That will make the kernel modules required for DRI. After that has done, copy the finished radeon.o to /lib/modules/2.4.x/kernel/drivers/char/drm/ with:
| Code: | mv /lib/modules/2.4.x/kernel/drivers/char/drm/radeon.o /lib/modules/2.4.x/kernel/drivers/char/drm/radeon.o.bak
cp radeon.o /lib/modules/2.4.x/kernel/drivers/char/drm/
|
You then need to edit /etc/X11/XF86Config. Add the following section at the end of the file:
| Code: |
Section "DRI"
Mode 0666
EndSection
|
Restart X.
To make sure that the DRI is working, just type
And you should see a bit that says:
| Code: | OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa DRI Radeon 20020221 AGP 1x
OpenGL version string: 1.2 Mesa 4.0.3
|
Or similar. If it says:
| Code: | OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 Mesa 4.0.3
|
Then you're DRI isn't setup properly.
Notes:
The M6 (aka Radeon Mobility) does about 420fps in glxgears. Without DRI it does ~100.
The M7 (aka Radeon 7500 Mobility) apparently works with this code. I can't confirm this as I don't have an ATI Radeon 7500 Mobility to test it on.
The Radeon 9000 Mobility in the 867/1GHz PowerBooks do not work with DRI as far as I know.
Hope this helps,
