Nvidia Kernel Modules

When a Nvidia client updates, we must get the kernel drivers to be updated with it. There are two kernel modules that must be updated. If there is a conflict between your Nvidia client and your kernel drivers check with: dmesg | grep "NVRM"
dmesg | grep "NVRM":
API mismatch: the client has the version 352.93, but NVRM: this kernel module has the version 352.79. Please NVRM: make sure that this kernel module and all NVIDIA driver NVRM: components have the same version.
Use lsmod and grep for nvidia to find the actual kernel module names:
-sh-4.1$ lsmod | grep nvidia nvidia_uvm 71483 0 nvidia 8531094 1 nvidia_uvm i2c_core 29132 2 i2c_i801,nvidia
With this information, I see two kernel modules with the name nvidia in them.
We can update them manually by doing:
rmmod nvidia_uvm rmmod nvidia modprobe nvidia_yvm modprobe nvidia
Preferably, we'd have a puppet module automate this task of updating nvidia kernel modules to match the version number of the nvidia client. Puppet Code:
exec {'unbreak-nvidia-after-driver-update': command => '/sbin/rmmod nvidia_uvm ; /sbin/rmmod nvidia ; /sbin/modprobe nvidia ; /sbin/modprobe nvidia', notifyonly => true, subscribe => [Package['nvidia']], }
