Hi,

I have an asus amd64 PC with a nvidia GeForce 8800 GT graphic card. This
PC is working fine with the gentoo-kernel and the nvidia proprietary
kernel module.

I want to experiment with the rt-kernel. It is 3 modules for the
nvidia card. 

- The nvidia proprietary module, I guess that this is not necessarily a
  good choice because it will not be patched for use with the rt-kernel.
  But I am not sure.

- The 2 others are with the kernel, nv and nouveau.

Which module will be best to use with the rt-kernel?

Ciao,
Dominique

nv only!

You can try nvidia, after faking the license for the kernel-rt by

sed -i \
    's/EXPORT_SYMBOL_GPL(migrate_enable);/EXPORT_SYMBOL(migrate_enable);/' \
    kernel/sched.c
 
  sed -i \
    's/EXPORT_SYMBOL_GPL(migrate_disable);/EXPORT_SYMBOL(migrate_disable);/' \
    kernel/sched.c
 
  sed -i \
    's/EXPORT_SYMBOL_GPL(__rt_mutex_init);/EXPORT_SYMBOL(__rt_mutex_init);/' \
    kernel/rtmutex.c
