Description Tom Smith 2009-09-17 04:26:34 UTC

I receive the following error when emerging nvidia-drivers-185.18.31 with my vanilla-sources-2.6.31 kernel with the -rt10 patch applied:

/var/tmp/portage/x11-drivers/nvidia-drivers-185.18.31/work/NVIDIA-Linux-x86_64-185.18.31-pkg2/usr/src/nv/nv.c: In function 'nv_alloc_file_private':

NVIDIA: left KBUILD.
nvidia.ko failed to build!

make: *** [module] Error 2

The init_MUTEX macro has been removed in the latest kernel. The fix seems pretty trivial, a patch is provided here:
http://lkml.org/lkml/2009/7/30/74

Reproducible: Always

Steps to Reproduce:
1. Install and compile a 2.6.31 realtime kernel
2. emerge nvidia-drivers-185.18.31

NVIDIA does not support the real time kernel patchset and so nor can we.

gotta love that "[proprietary company name here] don't support it so nor can we" attitude, !.
