[PlanetCCRMA] akmods planetccrma

[Ken Ellinwood]

Juan,

Enable the RPM Fusion repo if you haven't already and install kmod-fglrx in order to get the required dependencies, xorg-x11-drv-fglrx and xorg-x11-drv-fglrx-libs.  This might be best done while running under the stock Fedora kernel.  

Go to the RPM Fusion website and download the source rpm whose version matches the installed kernel module.  Install the source: sudo rpm -i fglrx-kmod-9.3-1.fc9.src.rpm.  This results in  /usr/src/redhat/SOURCE/fglrx-kmod-data-9.3.tar.bz2, which should be extracted in place.

Now boot into the RT kernel, console mode (run level 3)

cd /usr/src/redhat/SOURCES/fglrx
cp ./arch/x86/lib/modules/fglrx/build_mod/libfglrx_ip.a.GCC4 common/lib/modules/fglrx/build_mod/.
cd common/lib/modules/fglrx/build_mod/
edit firegl_public.c and change the text string on line 228 to "GPL"
,/make.sh
cd ..
./make_install.sh

During the next reboot, the /etc/init.d/fglrx will attempt to update xorg.conf to use the driver but will fail because it doesn't look for the driver in the location it was actually installed.  So the init script needs to be updated to expect the driver in /lib/modules/`uname -r`/kernel/drivers/char/drm/fglrx.ko.  Make this change and then reboot.

Thats it.  Hope it helps.

Ken

Yes, I did it a couple months back --  its a PITA.   As it turns out have to do it again because yesterday I let the system (Fedora 9) do a full update of 100 or so packages and now the driver just locks the system up.   I'm currently back on the default radeon driver.

I can't remember the exact details but it was something like this:

I downloaded the source rpm from RPM Fusion and installed it (without a rebuild) into /usr/src/redhat/SOURCES.  I got the same compile error and had to patch the source to get around that.  I think the patch I applied (by hand) is described here:  http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg354750.html.  Next I had to fiddle with symlinks in the source tree until the link succeeded.  Its a two step process.  Compile in one directory, then
 insall from another (or so I seem to remember).  I might rebuild mine tonight - I still have the source tree intact from the first successful build -- so I may have better information tomorrow.

Hi,

I am trying to build fglrx-kmod on Kernel
'2.6.26.8-1.rt16.1.fc10.ccrma.i686.rt' using rpmfusion akmods.

After installing akmods and akmod-fglrx when I boot PlanetCCRMA's 'rt'
kernel, akmods fails to build fglrx-kmod. 

If i try to build fglrx-kmod with,
 
 'akmodsbuild -k
 \
2.6.26.8-1.rt16.1.fc10.ccrma.i686.rt /usr/src/akmods/fglrx-kmod-9.3-1.fc10.src.rpm'

So far I get a build error with the following complain:

FATAL: modpost: GPL-incompatible module fglrx.ko uses GPL-only symbol
'__rcu_read_lock'
make[2]: *** [__modpost] Error 1
make[1]: *** [modules] Error 2
make[1]: Leaving directory
`/usr/src/kernels/2.6.26.8-1.rt16.1.fc10.ccrma.i686.rt'
make: *** [kmod_build] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.m6lAGE (%build)

I am not so sure if akmods doesn't work with 'rt' kernels or if I am
missing something. kernel-rt-devel is also installed.

Has anyone succeed building modules using akmods and PlanetCCRMA.

Main problem with radeon out-of-the-box drivers is that XORG and ACPI
are pretty much unstable on F10.

  Thanks,
