[LAU] ATI Radeon - binary driver - with linux realtime kernel

[Emanuel Rumpf]

Hi

I managed to install the ati-radeon driver on my realtime-kernel driven system.
( Debian GNU/Linux, 2.6.31-rt11 )
For your information, here is how I did.

I downloaded the linux driver from:
http://support.amd.com/us/gpudownload/Pages/index.aspx

This information applys to
"ATI Radeon HD 3xxx Series" only, but other drivers might require
likewise changes.
Installer used: ati-driver-installer-9-10-x86.x86_64.run


---------

1. Start the installer. But don't continue. This will extract the
installer-files to the current directory.
2. Open a new terminal, change to the extracted directory (called
something as fglrx-install.08df92 ).

3. CHANGE THE FILE: firegl_public.c  in
install/lib/modules/fglrx/build_mod/firegl_public.c
(and maybe: common/lib/modules/fglrx/build_mod/firegl_public.c )

AS FOLLOWS:


THIS (LINE ~ 1028):
for (i = 0; i < __KE_MAX_SPINLOCKS; i++)
    dev->spinlock[i] = SPIN_LOCK_UNLOCKED;

CHANGES TO:
for (i = 0; i < __KE_MAX_SPINLOCKS; i++)
    DEFINE_SPINLOCK( dev->spinlock[i] );


THIS (LINE ~ 5001):
init_MUTEX(&(mutex_obj->mutex));

CHANGES TO:
semaphore_init( &(mutex_obj->mutex) );



4. go back to the installation terminal, continue and finish the installation.


good luck.
