Trying to run linux-3.18 with proprietary nvidia-drivers-340 shows:

Tried this with gentoo-sources-3.18.5 and nvidia-drivers-340.76.
The last part of the patch in nv.c doesn't seem to exist. And even with the patch, I get the kernel panic and a freezing system. |

I don't need the patch either since there is x11-drivers/nvidia-drivers-340.76
Runs well without issues using x11-base/xorg-server-1.16.3-r1 |

After some editing it works even on the kernel 3.19.

This is for patching the linux kernel code, or for patching parts of the nvidia drivers?
Same as musv, i don't have this files in my linux-kernel directory.
The hard part for me is that i need to use the old 340.76 drivers for my now unsupported old nvidia cards. Its a mess that nvidia don't release the "old" part for self unsupported hardware of the old drivers/specifications to the free open source driver team.
Or did they and i could safely use the nv-drivers?
Edit: Got it, this is a patch to apply for the Nvidia-drivers. The line numbers with 340.76 slightly different and the Line with the
| Code: | | return nvidia_ioctl(NV_FILE_INODE(file), file, cmd, i_arg); |
I had to change, as the Patch recommended to:
| Code: | | return nvidia_ioctl(file->f_path.dentry->d_inode, file, cmd, i_arg); |
Did not reboot now but think that this will work, because i had no compiler error. |

The directory
/etc/portage/patches/x11-drivers/nvidia-drivers-340.76
means this only applys to nvidia-drivers-340.76 |
