No... 1) Bad idea to mix named field initializers with positional Here
you're initializing a nonexistent field 2) The unmap method is gone
from vm_operations_struct because this is now handled generically. Just
remove it.

[non-kernel patch] Re: bug of Nvidia (0.9.5) Drivers in 2.4 Kernel Enviroment
(replies - cc: [EMAIL PROTECTED])
Driver should work after applying the following patch. I'm not a kernel
hacker so I don't know how good a solution this is (especially suspicious
of the work around in os-interface.c) but X works on my machine and it has
not crashed (yet) - have not tried any OpenGL though.
Apply this to the extracted tar.gz version of the driver and compile that.
Don't just try and rebuild the binary rpm from the spec file as it will
extract
the tar.gz again and all changes will be lost (there should be a tar.gz
hanging
around once the src.rpm has been installed).

You can either: 1> Get on irc (Server: irc.openprojects.net, Channel #nvidia) and request the patch from there. (You need to be able to do DCC transfers for this to work). There is patches for 2.4.0-test1[0-3] and for 2.4.0-[prerelease/final], so get what you need that way. The bot to request from is usually iCE-DCC, and you can request a list using '/msg iCE-DCC xdcc list' and request a file using eg: '/msg iCE-DCC xdcc send #10' (if you wanted file 10 that is). 2> Alternatively, if you e-mail me, I could probably forward you the patch or, if people don't mind too much, I could post it to the list (I'll wait for comments on this first!). The patch is about 1k for test10, and about 3k for prerelease/final. Remember, this patches Nvidia's driver shim source code, and not the kernel. You could unpack the .src.rpm and add the patch to the compile process if you were really game, but I did it from the .tar.gz and it works fine for me. YMMV of course. BTW: Common problem is that people complain that the make still gets includes wrong. Make sure you compile the kernel and it's modules completely. I compiled the kernel and modules, rebooted into the new kernel, and then compiled the Nvidia driver. The last step of Nvidia's make process (for the .tar.gz) is to actually insmod the driver to make sure it worked, which will probably fail on any other version of the kernel. Of note: Nvidia have a new driver in the works, that should be much nicer re: kernel interface. -- -=[ Stuart Young (Aka Cefiar) ]=--- | http://amarok.glasswings.com.au/ | [EMAIL PROTECTED] | --- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
