Hi all, has anyone patched the nvidia binary installer for 2.6.33-rt?
Would like to have a look. I use nvidia-beta myself, but from previous
-rt kernels I know I can figure out the patch from that given the
patch for any other nvidia installer.

Hello,

I don't think the problem is rt-related, but generally to the vanilla version.

Kind regards,
Xavier Miller.

actually, it is ... atomic_spinlock_t was renamed to raw_spinlock_t, and 
apparently semaphore_init isn't there any more ... 

the first issue is trivial, for the second, i didn't follow the rt patches 
closely enough ...

I have absolutely no idea if this is the best way to handle the semaphore_init
issue, I don't even know what a semaphore is, but I submitted a simple patch at
http://www.nvnews.net/vbulletin/showthread.php?t=148509 anyway. It builds and
appears to be working, but I'd like some verification that sema_init(mutex,1) is
a valid substitute for semaphore_init(mutex).

Works here as well (for nvidia 195.36.08). Many thanks, Jonathan. Such
a simple patch compared to the previous one for 2.6.31-rt.

Would still appreciate information from someone who knows the code
about sema_init(mutex,1) though =).

The patch is much easier now because the spinlock functions are
nicely wrapped in NV_... macros in nvidia's patch.

Well, it should work the same.  Still I wouldn't be surprised if this
should be a mutex instead, I havn't looked.

Best regards
Uwe
