Description Juan Magallon 2014-12-18 02:12:05 CET

Using the nVidia propietary driver, I get this error on dmesg:

[   23.911482] No drm_driver.set_busid() implementation provided by nv_drm_driver [nvidia]. Use drm_dev_set_unique() to set the unique name explicitly.

followed by a backtrace.
Possible solution/patch is here:

https://devtalk.nvidia.com/default/topic/796559/linux/kernel-3-18-warning-no-drm_driver-set_busid-implementation-provided-by-nvidia_frontend_exit_modu/

Could you pick the patch ?
TIA

For some reason the patch is incorect, it does not build with current kernel.
The hunks like:

-    return nvidia_ioctl(file->f_dentry->d_inode, file, cmd, i_arg);
+    return nvidia_ioctl(file->f_path.f_dentry->d_inode, file, cmd, i_arg);

should look like

-    return nvidia_ioctl(file->f_dentry->d_inode, file, cmd, i_arg);
+    return nvidia_ioctl(file->f_path.dentry->d_inode, file, cmd, i_arg);

Note the chage from 'f_dentry' to just 'dentry'.
There are 3 of them.

Probably this was introduced in 3.18.1, and patch was born for 3.18.0...

Nope, it was me messing it up with a too quick c/p :/

fixed in nvidia-current-340.65-3.mga5 and confirmed with the kmod-nvidia-current-340.65-5.mga5 build
